A rug can be beautiful on its own and still look completely wrong once it reaches the room. I have seen this happen most often with rugs that are too small. They sit in the middle of the floor like a decorative island while the sofa, chairs, or dining table hover around them. The color may be perfect, the pattern may suit everything, and the room still feels slightly disconnected. It is easy to blame the furniture arrangement when the real problem is simply that the rug does not reach far enough.
Rug sizing is not about following one rigid decorating rule. The right dimensions depend on the furniture, walking paths, door clearance, and shape of the room. A 9-by-12-foot rug might look generous in one living room and undersized in another. I measure the furniture arrangement rather than shopping by the room’s name, but standard sizes are still helpful starting points. This guide explains how I choose rugs for living rooms, bedrooms, dining rooms, kitchens, hallways, offices, nurseries, bathrooms, and outdoor spaces without guessing from a product photograph.
Measure the Furniture Arrangement, Not Just the Room
Room measurements tell me what can physically fit, but they do not tell me which rug will look right. I first measure the furniture grouping the rug needs to connect. In a living room, that means the sofa and chairs. In a dining room, it includes the table and chairs when they are pulled out. In a bedroom, the bed and the amount of rug I want visible at the sides and foot matter more than the distance between all four walls.
I make a quick sketch and write the furniture measurements directly on it. Nothing needs to be drawn beautifully. I include doors, floor vents, fireplace hearths, built-ins, and narrow walkways because a rug should not create trouble in those places. This simple plan is much more useful than relying on a photo taken with a wide-angle lens, which can make both the room and rug look larger than they are.

Use Painter’s Tape Before Ordering
Painter’s tape is the cheapest rug-sizing tool I know. I mark the complete rug outline on the floor and leave it there long enough to walk around the room, open doors, and look at it from the hallway. The taped shape quickly shows whether an 8-by-10 rug will connect the chairs or stop awkwardly in front of them.
Look at the corners as well as the long sides. A rug may clear the fireplace on paper but crowd the hearth at one corner. It may fit beneath the bed but catch the bedroom door. I also take a photograph of the taped area from the main entrance. Seeing the outline flattened in a picture makes undersized rugs especially obvious, and it is much easier than returning a heavy rolled rug.
Understand Common Rug Sizes
The most common rectangular rug sizes include 3 by 5 feet, 4 by 6 feet, 5 by 7 feet, 5 by 8 feet, 6 by 9 feet, 8 by 10 feet, 9 by 12 feet, and 10 by 14 feet. Not every manufacturer follows those dimensions exactly. A rug described as 8 by 10 might be several inches shorter in each direction, which matters when the layout already has tight margins.
Round rugs commonly come in 4-, 6-, 8-, and 10-foot diameters, while runners vary widely in length. Always read the actual measurements rather than trusting the size category alone. Handmade rugs may be slightly irregular, and washable rugs can change subtly after laundering. If the arrangement needs every inch of a 9-by-12 footprint, a rug measuring 8 feet 7 inches by 11 feet 6 inches may not create the result you pictured.
Leave a Deliberate Border of Exposed Floor
A rug usually looks best when some flooring remains visible around it. That border frames the rug and keeps the room from looking carpeted almost to the wall. In many average rooms, 12 to 24 inches of exposed flooring works well. Small rooms may need a narrower border, while a large room can handle more.
Consistency matters more than achieving one exact number. A rug positioned three inches from one wall and two feet from another often looks as though it shifted accidentally. Furniture, doorways, and architectural features may prevent a perfectly even border, but the placement should still feel deliberate. I center the rug within the furniture arrangement first and then judge its relationship to the walls.
What Size Rug Works in a Small Living Room?
A 5-by-7 or 5-by-8 rug may work in a genuinely compact living room when it sits beneath a coffee table and reaches close to the seating. However, a rug that touches none of the furniture often makes the arrangement look smaller. If the room can accommodate it, a 6-by-9 or 8-by-10 rug usually creates a more connected result.
I aim to place at least the front legs of the sofa and main chair on the rug. That small overlap visually ties the seating together. When the furniture has to sit entirely off the rug, I leave a clear, intentional gap rather than allowing the rug to stop an inch short of the sofa. That almost-but-not-quite placement looks like a measuring mistake.
What Size Rug Works in an Average Living Room?
An 8-by-10 rug is a useful starting point for many average living rooms. It often allows the front legs of a standard sofa and two chairs to rest on the rug while leaving a visible floor border. A 9-by-12 gives the arrangement more breathing room and may allow all the seating to sit fully on it.
The correct orientation depends on the room. In a long living room, the rug’s longest side will usually follow the sofa and the room’s length. Rotating it the other way can leave the chairs disconnected and create narrow strips of rug in unhelpful places. I line up the rug with the main furniture arrangement rather than automatically centering it between the walls.
Use an All-Legs-on Rug in a Large Living Room
A large living room often looks more settled when the sofa, chairs, and side tables sit entirely on the rug. A 9-by-12 or 10-by-14 rug may be needed, depending on the furniture. This approach defines the seating zone and prevents the pieces from appearing scattered across a broad floor.
Leave enough rug behind each piece that the back legs are not balancing at the edge. Six to 12 inches beyond the furniture often looks more comfortable than a rug that ends directly beneath the legs. I also check side-table placement. A table half on and half off a thick rug may wobble, even if the sofa itself sits correctly.
Use the Front-Legs-on Arrangement When Space Is Tighter
The front-legs-on arrangement is practical because it connects the furniture without requiring a room-size rug. The front legs of the sofa and chairs rest several inches onto the rug, while the back legs remain on the floor. This commonly works with an 8-by-10 rug in an average seating area.
Place enough of each piece on the rug that the overlap looks intentional. Resting only the front half-inch of a sofa leg on the edge creates an unstable, pinched appearance. I like the rug to extend beneath at least the front portion of the furniture and continue beyond each side of the sofa. If it is narrower than the sofa, the whole grouping can look top-heavy.
Size a Rug for a Sectional Sofa
Sectionals create a large visual footprint, so they usually need a larger rug than expected. An 8-by-10 can work with a compact apartment sectional, but many standard sectionals look better with a 9-by-12. A large U-shaped sectional may need a 10-by-14 rug or a custom size.
The rug should reach beneath the front legs of every sectional component rather than connect only one side. I also want it to extend into the open seating area, giving the coffee table and any accent chair a shared foundation. A small rug tucked into the empty center of an L-shaped sectional can look like a mat rather than part of the room.
Position a Rug in a Narrow Living Room
Long, narrow living rooms require more attention to proportion than standard size charts can provide. A rug that is too wide may crowd the walls, while one that is too short can divide the seating arrangement awkwardly. I follow the direction of the room and choose a rug long enough to connect the sofa with the chairs or console at the opposite end.
A 6-by-9 or 8-by-10 may work, but the furniture measurements should make the final decision. Avoid placing the rug halfway beneath a doorway or allowing one corner to obstruct the main path. In some very narrow rooms, using a long vintage-style rug beneath only the central seating zone can look more natural than forcing in a broad conventional size.
How Much Rug Should Show Around a Coffee Table?
A coffee table needs enough rug around it that the table does not consume the entire pattern. As a rough guide, I like to see 12 to 18 inches of rug between the coffee table and the surrounding seating. This leaves legroom and prevents the rug from looking like it was purchased only as a pad for the table.
The exact distance depends on the room and the depth of the sofa. A narrow space may need a smaller gap, while a large seating arrangement can handle more. The coffee table should sit completely on the rug. If its legs fall near a raised rug edge, the table may rock and the arrangement will look poorly measured.

What Size Rug Works Under a Dining Table?
The rug under a dining table must account for moving chairs, not just the table itself. I add at least 24 inches to every side of the tabletop. Thirty inches is even more comfortable when the room allows it. This gives chair legs room to remain on the rug when someone sits down or gets up.
For a rectangular table measuring 40 by 72 inches, adding 24 inches to each side creates a minimum rug footprint of about 88 by 120 inches. That points toward an 8-by-10 rug, although a 9-by-12 may feel better in a generous room. Measuring the table alone is the most common reason dining rugs end up too small.
Choose an 8-by-10 or 9-by-12 Dining Rug
An 8-by-10 rug often works beneath a dining table that seats four to six people. A 9-by-12 is usually more suitable for a table seating six to eight, particularly when chairs occupy the ends. Large tables may require a 10-by-14 rug.
These are starting points, not guarantees. A six-seat table with unusually deep chairs might need more room than a narrow eight-seat table with compact seating. Pull every chair out to a comfortable sitting position and measure the complete occupied area. If the rear legs fall beyond the taped rug outline, increase the size.
Match a Round Rug to a Round Dining Table
A round rug can beautifully echo a round dining table and soften a square breakfast room. Measure the table’s diameter and add at least 48 inches. A 48-inch table generally needs an 8-foot round rug to provide 24 inches of clearance on all sides.
Do not size the rug based on the tabletop before checking the chair depth. Upholstered dining chairs can require more space than slim wooden ones. I pull the chairs out as they would be during a meal and measure across the entire arrangement. A round rug that barely clears the table base will cause the rear chair legs to catch every time someone sits down.
Use a Rectangular Rug With an Oval Table
An oval dining table usually sits comfortably on a rectangular rug because both shapes share a long direction. The rug should follow the table’s length and extend evenly beyond both rounded ends. This creates enough space for the end chairs without forcing the rug to mimic every curve.
An oval rug is another option, though sizes and patterns are more limited. I would choose it because it suits the room, not because an oval table supposedly requires one. A well-proportioned rectangular rug is easier to find, often less expensive, and usually simpler to position with nearby walls and doorways.
Avoid a High-Pile Rug in the Dining Room
Size is only half the dining-room decision. A thick or shaggy rug makes chairs difficult to move and collects crumbs deep in the fibers. A low-pile wool rug, flatweave, or durable synthetic construction is easier to use beneath a table.
The rug should also have enough weight to lie flat. Lightweight corners that curl beneath chair legs become irritating and unsafe. A suitable rug pad keeps the surface stable and protects the floor, but the combined thickness should still allow chairs to slide without catching.
What Size Rug Works Under a King Bed?
A king bed usually needs a 9-by-12 rug for a balanced arrangement. Positioned perpendicular to the bed, it can extend beneath the lower two-thirds and leave a comfortable amount visible at the sides and foot. A 10-by-14 rug creates a more generous look and may also support the nightstands.
An 8-by-10 rug can work in a tight king bedroom, but it may provide only a narrow landing strip at the sides. Before buying, mark the bed’s width and rug outline on the floor. Remember that most of the rug will disappear beneath the mattress, so the amount visible matters more than the impressive dimensions printed on the label.
What Size Rug Works Under a Queen Bed?
An 8-by-10 rug is the dependable choice for a queen bed. It can sit beneath the lower two-thirds of the bed and extend beyond both sides. A 9-by-12 provides more coverage and may reach beneath the nightstands, making it suitable for a larger bedroom.
A 6-by-9 rug is possible when the room is small and the rug begins in front of the nightstands. The visible side sections will be narrower, so use painter’s tape to make sure they still feel useful when stepping out of bed. A 5-by-7 rug placed crosswise beneath a queen usually looks lost and provides very little functional coverage.
What Size Rug Works Under a Full Bed?
A 6-by-9 rug works well under many full-size beds, particularly when it begins below the nightstands. An 8-by-10 creates a more spacious border and is a good choice when the room has enough floor area.
A 5-by-7 may work in a very compact room, but placement becomes important. It should extend from beneath the lower portion of the bed and show at the foot rather than disappear almost completely underneath. If the larger size crowds the walls, two runners along the sides may be a more practical solution.
What Size Rug Works Under a Twin Bed?
A 5-by-7 or 5-by-8 rug can sit beneath a twin bed and extend beyond its side and foot. In a child’s room, a 6-by-9 may cover more of the play area and help connect the bed with a small dresser or reading chair.
If two twin beds share a room, one large rug can unite them. Depending on the spacing, an 8-by-10 or 9-by-12 may fit beneath the lower portions of both beds. Another option is one runner between the beds, though it should be wide enough to feel intentional rather than like a narrow strip covering the center seam.
Decide Whether the Nightstands Sit on the Rug
Both arrangements can work. Beginning the rug in front of the nightstands uses less rug and concentrates the softness where bare feet land. This is often the easiest approach in an average bedroom.
Placing the rug beneath the bed and nightstands creates a more luxurious, fully grounded look but requires a larger size. Make sure all four legs of each nightstand sit on the same level. A nightstand with front legs on a thick rug and back legs on bare flooring may tilt, which is especially annoying when it holds a lamp or glass of water.
Try Runners Beside the Bed
Two matching runners can provide softness on both sides of a bed without covering most of a beautiful wood floor. They are useful when a large rug would interfere with doors, floor vents, or closely positioned furniture.
The runners should be long enough to relate to the bed rather than sit like small bath mats beside it. Begin them around the nightstand area and let them continue toward the foot. Exact symmetry is not always possible, but similar spacing on both sides creates a finished look.
What Size Rug Works in a Nursery?
An 8-by-10 rug often works in a nursery because it can connect the crib, chair, and dresser while leaving a comfortable play surface. In a smaller room, a 5-by-7 or 6-by-9 may sit in the central open area without running beneath every piece.
Choose a low or medium pile that is comfortable on knees but not difficult to clean. Long loose fibers can hide small objects, and strongly raised patterns may make wheeled storage or furniture wobble. The crib must remain stable, with all of its feet on the same level. I never use rug placement to solve an unsafe furniture arrangement.
What Size Rug Works in a Home Office?
The office rug should be large enough for the desk and chair to function together. When a rolling chair moves backward, it should remain on the rug rather than drop over the edge. For a standard desk, a 5-by-7 may be too short; a 6-by-9 or 8-by-10 often provides better chair clearance.
Low-pile rugs are far easier beneath office chairs. A thick rug can make rolling difficult and may show deep wheel marks. If the desk faces into the room, consider how the rug looks from the doorway and whether it also needs to connect a bookcase or guest chair.
What Size Rug Works in a Kitchen?
A 2-by-3 or 3-by-5 rug works in front of a sink, while a runner suits a galley kitchen or the aisle between cabinets and an island. The runner should be several inches narrower than the walkway so it does not curl against the toe kicks.
Length depends on the cabinet run. I prefer a runner that relates to the working area rather than one that stretches awkwardly from wall to wall. Leave clear space at both ends, and avoid blocking appliance doors. A washable, low-profile rug with a secure pad is much easier to live with around food and water.
Size a Runner Between the Island and Cabinets
Measure the clear floor between the island and the opposite cabinet fronts. Subtract enough width to leave a visible border on both sides. A 2½- or 3-foot-wide runner often works, but every kitchen aisle is different.
Open the dishwasher, oven, and refrigerator before finalizing the size. A thick rug edge can prevent an appliance door from opening smoothly, while an unsecured runner may shift whenever someone turns at the sink. In a hardworking kitchen, practical clearance matters more than extending the rug to every cabinet.
What Size Rug Works in an Entryway?
A 3-by-5 rug is a common choice for a modest entry, while a larger foyer may accommodate a 4-by-6, 5-by-7, or round rug. The door must open freely over the rug and pad. Measure the clearance beneath the door before choosing a thick construction.
The rug should feel related to the entrance architecture. In a long narrow entry, a runner may guide the eye inward. In a square foyer, a round or rectangular rug centered beneath the light fixture can feel more balanced. Leave enough flooring visible that the rug does not resemble wall-to-wall carpet cut slightly too short.
Choose the Correct Hallway Runner
A hallway runner should leave several inches of flooring visible on both sides. Many runners are 2 to 3 feet wide, but the right width depends on the hallway. A runner that nearly touches both walls makes a narrow passage feel tighter and may curl against the baseboards.
At the ends, I generally leave 6 to 12 inches of visible floor, adjusting for doors and transitions. The runner does not need to fill every inch of the hallway. If the hall is exceptionally long, two coordinated runners may be easier to find than one custom length, but leave a deliberate gap rather than placing them almost together.
What Size Rug Works in a Bathroom?
A small 2-by-3 rug may be enough in front of a vanity or tub. A double vanity often looks better with a 2-by-6 runner than with two unrelated bath mats. In a larger bathroom, a 4-by-6 rug can occupy the open floor without interfering with doors or plumbing fixtures.
Bathroom rugs need frequent washing and quick drying, so I do not select them on size alone. Check that the rug does not slide on tile and that doors clear its pile. It should sit outside the shower’s main splash area unless it is designed to handle regular moisture.
Use a Round Rug in a Square Room
A round rug can soften a boxy room and highlight one central feature, such as a round dining table, pedestal table, or reading chair. It also works in a square entry where a rectangular rug creates awkward corners.
The furniture still needs to relate to the circle. A round rug beneath a table should extend beyond every chair, while one in an entry should leave a visible floor border around its full circumference. Do not choose a small round rug merely because it is decorative. If it cannot connect anything, it may look like an oversized coaster.
Size a Rug for an Open-Plan Room
In an open floor plan, rugs can define the living and dining zones without constructing walls. Each rug should be large enough for its own furniture group. The living-room rug connects the seating; the dining rug supports the table and pulled-out chairs.
The rugs do not need to match, but they should not compete. I look for a connection in color, texture, or pattern scale. Leave a visible stretch of flooring between them so each zone has a clear boundary. Two rugs that almost touch can look like an unsuccessful attempt to create one larger rug.
Layer a Small Vintage Rug Over a Larger Base
A special vintage rug may be too small for the room but too beautiful to ignore. Layering it over a larger neutral rug gives it the footprint it lacks. A jute or quiet flatweave can connect the furniture, while the smaller patterned rug adds color and character.
The top rug needs to look deliberately positioned. Centering it beneath the coffee table is often the easiest approach, although a slightly offset placement can work in a relaxed room. Use a suitable rug pad or gripper between layers so the smaller rug does not wrinkle or slide. Too many thick layers can become a tripping hazard.
Account for Doors, Vents, and Fireplace Hearths
A rug can be the correct size for the furniture and still fail the room. Entry doors may scrape over it, floor vents can disappear beneath it, and raised fireplace hearths may prevent it from lying flat. I mark these obstacles before deciding on dimensions.
Do not cut off airflow from a floor vent or force a rug edge beneath a heavy door. Sometimes moving down one standard size solves the problem; in other rooms, an unusual or custom size is worth considering. The best-looking rug arrangement is not successful if the door has to be lifted every time it opens.
Choose the Rug Pad After Choosing the Rug
A rug pad keeps the rug from shifting, protects the floor, and adds comfort. It should be slightly smaller than the rug so it remains hidden beneath the edges. A pad that sticks out looks unfinished, while one that is far too small may allow the corners to move.
Thickness depends on location. A plush pad can make a living-room rug feel luxurious, but it may raise the rug too much beneath a door or dining chair. Thin nonslip pads are useful in kitchens and hallways. Check that the pad material is compatible with the flooring, particularly with certain vinyl, laminate, and finished wood surfaces.

Common Rug-Sizing Mistakes
The most common mistake is choosing a rug based on price before measuring the furniture. Smaller rugs are less expensive, which makes them tempting, but an undersized rug may never make the room feel finished. Replacing it later costs more than waiting for the appropriate size.
Other mistakes include ignoring pulled-out dining chairs, placing a rug only beneath the coffee table, buying a bedside rug that vanishes under the bed, and forgetting door clearance. I also avoid arranging furniture with one leg barely touching the rug. Either place the piece meaningfully on it or keep it clearly off.
Quick Room-by-Room Rug Size Chart
The following sizes are useful starting points, but furniture measurements should make the final decision.
| Room or arrangement | Common starting rug size |
|---|---|
| Small living room | 5 × 7, 5 × 8, or 6 × 9 feet |
| Average living room | 8 × 10 feet |
| Large living room | 9 × 12 or 10 × 14 feet |
| Compact sectional | 8 × 10 feet |
| Standard sectional | 9 × 12 feet |
| Four-seat dining table | 6 × 9 or 8 × 10 feet |
| Six-seat dining table | 8 × 10 or 9 × 12 feet |
| Eight-seat dining table | 9 × 12 or 10 × 14 feet |
| King bed | 9 × 12 feet |
| Queen bed | 8 × 10 feet |
| Full bed | 6 × 9 or 8 × 10 feet |
| Twin bed | 5 × 7, 5 × 8, or 6 × 9 feet |
| Nursery | 5 × 7, 6 × 9, or 8 × 10 feet |
| Home office | 6 × 9 or 8 × 10 feet |
| Small entry | 3 × 5 feet |
| Kitchen sink area | 2 × 3 or 3 × 5 feet |
| Galley kitchen | 2 × 6, 2½ × 8, or 3 × 10 feet |
| Bathroom vanity | 2 × 3 or 2 × 6 feet |
Use the table to narrow the options, then tape the likely sizes onto the floor. A standard chart cannot account for an extra-deep sofa, oversized dining chair, off-center fireplace, or bedroom door that swings into the only available rug position.
Frequently Asked Questions
Is an 8-by-10 Rug Big Enough for a Living Room?
An 8-by-10 rug works well in many average living rooms. It often allows the front legs of the sofa and chairs to rest on the rug while leaving a visible floor border.
A large sectional or wide furniture arrangement may need a 9-by-12. Measure the complete seating group rather than assuming the standard size will work.
Should a Rug Go Under the Sofa?
The rug should normally extend beneath at least the sofa’s front legs. This anchors the sofa to the rest of the seating arrangement and prevents the rug from floating beneath the coffee table.
In a large room, the entire sofa may sit on the rug. If the sofa remains completely off, leave an intentional gap instead of letting the rug stop almost beneath it.
How Far Should a Rug Extend Beyond a Sofa?
I like a living-room rug to extend at least 6 inches beyond each side of the sofa. A wider extension can look more generous and may be necessary to connect nearby chairs or tables.
A rug narrower than the sofa often makes the arrangement look top-heavy. Tape the outline before ordering so the side margins are easy to judge.
Can a Living-Room Rug Be Too Big?
Yes. A rug that nearly touches every wall can make the room look like it has poorly fitted carpet. It may also block doors, vents, or a fireplace hearth.
Leave a visible border of flooring wherever possible. The rug should define the furniture grouping rather than fill the entire room automatically.
Should Dining Chairs Stay on the Rug When Pulled Out?
Yes. Keeping all four chair legs on the rug prevents the rear legs from catching on its edge. Add at least 24 inches of rug beyond every side of the tabletop.
Thirty inches provides more comfort for deep or upholstered chairs. Test the size by pulling the chairs into a realistic seated position before measuring.
Is an 8-by-10 Rug Large Enough for a Dining Table?
An 8-by-10 often works beneath a table seating four to six. The exact result depends on the table dimensions and chair depth.
Measure the tabletop and add at least 48 inches to both its length and width. If the total exceeds the rug dimensions, move up to a 9-by-12.
What Size Rug Goes Under a Queen Bed?
An 8-by-10 is the most dependable choice. It usually provides a useful strip at both sides and the foot when placed beneath the lower two-thirds of the bed.
A 6-by-9 can work in a smaller bedroom, while a 9-by-12 creates a more generous arrangement and may accommodate the nightstands.
What Size Rug Goes Under a King Bed?
A 9-by-12 works for most king beds. A 10-by-14 offers more coverage and is better suited to a large bedroom or an arrangement including nightstands.
An 8-by-10 may fit beneath the bed but often leaves only narrow strips visible. Mark the outline before deciding whether those strips are wide enough to be useful.
Does the Rug Need to Go Under the Nightstands?
No. Starting the rug in front of the nightstands is a common and practical arrangement. It places more of the rug where people step out of bed.
A larger rug can include the nightstands for a fully grounded appearance. Keep each nightstand level by placing all of its legs either on or off the rug.
Can You Put a Round Rug Under a Rectangular Table?
Yes, provided the rug is large enough for the table and pulled-out chairs. However, matching the shapes is generally easier because the furniture uses the rug area more efficiently.
A round rug may work when the room itself is square and the contrast is intentional. Tape the full circle on the floor to make sure the corners of the table do not appear cramped.
Should a Hallway Runner Cover the Entire Hall?
No. A runner usually looks better with flooring visible on both sides and at each end. It should guide movement without resembling narrowly cut carpet.
Leave enough room for doors to open and for flooring transitions to remain clear. In a long hallway, choose a suitable standard length or use two rugs with an obvious gap.
Do You Need a Rug Pad?
A rug pad is usually worthwhile. It helps prevent movement, protects the flooring, and can make a thin rug more comfortable.
Choose the pad according to the rug, location, and floor material. Trim it slightly smaller than the rug so it remains invisible beneath the edges.
Final Thoughts
The right rug size is the one that supports the furniture arrangement instead of sitting apart from it. Living-room rugs should connect the seating, dining rugs must allow chairs to move, and bedroom rugs need to provide a comfortable landing beside the bed. Standard dimensions help narrow the choices, but they cannot replace measuring the actual furniture.
Before ordering, mark the rug with painter’s tape and use the room normally. Open doors, pull out chairs, walk around the bed, and look from the hallway. That small test catches most sizing mistakes before a heavy rug arrives. A rug does not need to fill the entire room, but it should be generous enough to make everything around it feel as though it belongs together.
