Enter your room and furniture sizes. See the footprint to scale, compare both orientations, and find out exactly how much space is left after your chosen clearance.
Your room fit estimate
As entered: furniture + clearance needs 156 in × 74 in.
Space remaining across the room: 12 in in width and 70 in in depth.
Room: 168 in wide × 144 in deep
13.2% furniture area / room area
47.7% furniture + clearance / room area
Required width = 84 in + 36 in left + 36 in right = 156 in.
Required depth = 38 in + 0 in back + 36 in front = 74 in.
Rotation turns the furniture and its clearance together. We prefer an orientation that fits, then the one with the most room left in its tightest dimension. The percentages describe area, not how easy it is to walk through the room.
One piece in an empty rectangular zone. Door swings, other furniture, connected walkways, height and delivery access are not checked. A 36-inch clearance alone does not establish wheelchair access; turning and approach spaces need their own checks.

By ItemFits · Calculation methods and limitations
You’ve found the right piece for your room. Before delivery day, there’s one more thing to check: every doorway, turn and flight of stairs between the truck and its final spot.
A few careful measurements can help you spot problems before they become failed deliveries, damaged walls or unexpected returns. Use the calculator above to explore your fit question, and follow this guide to measure the full route.
Why all three dimensions? A sofa’s width alone cannot determine doorway fit. Its height and depth affect possible orientations, while the space on either side determines whether there is room to turn. A doorway check also does not establish that the remaining delivery route is clear.
01 / The item
Measure the outermost points of the item in the condition it will be moved.
Packaging matters. Measure the actual packaged dimensions if the wrapping or box will stay on; don’t rely on a standard allowance.
02 / The opening
Side-wall clearance matters when rotating a large item. Measure every doorway on the route, including interior doors.
Where possible, plan for 1–1.5 inches of extra clearance on each side for handling. This is a planning allowance, not a fit guarantee. Trim and hardware that reduce the opening must be included.
Between the openings
A wide door can open onto a corner that stops a long piece. Measure both corridors and describe the turn.
Record what you measured: clear space between obstructions or wall-to-wall dimensions plus the obstructions. Do not deduct the same railing or trim twice.
03 / The climb
A landing smaller than the item’s depth may restrict rotation. Landing size alone does not settle the fit: the item’s orientation, railings and overhead space matter too.
04 / The lift
Check both the opening and the interior cabin.
A large cabin does not help if the item cannot clear the door. Check the approach, turning room and the building’s loading rules as well.
05 / The pinch points
The most restrictive point often determines whether the route works. A straight section that fits may still lead to a turn that does not.
06 / Before arrival
Make room to use it
Tape out the piece and the space you need around it. Try opening drawers, pulling out chairs and walking from the door to your seat.
| Space | Starting clearance | What to check |
|---|---|---|
| Main walking path | 36 in / 91.4 cm | Keep a continuous clear route. Turns, doors and passing people can need more room. |
| Sofa to coffee table | 14–18 in / 35.6–45.7 cm | A reach and legroom zone; do not count this gap as your main walkway. |
| Dining table to wall | 36 in / 91.4 cm; try 42–48 in / 106.7–121.9 cm for through traffic | Measure from the tabletop edge. Test your actual chairs with someone seated. |
| Walkable side of a bed | Try 30–36 in / 76.2–91.4 cm | Include the frame, nightstands and the space needed to make the bed. |
| Desk or dresser | Start with 36 in / 91.4 cm in front | Measure the chair pulled back or the drawer fully open, then allow any passing space. |
Sources: Crate & Barrel’s coffee table guide recommends a 14-inch sofa gap; its dining table guidance uses at least 36 inches to walls or furniture. The broader ranges above are planning suggestions to test in your room. For accessibility, consult the U.S. Access Board’s route guidance: a width value alone does not cover doors, turns or approach space.
A 60 × 80 in mattress centered against one wall leaves 30 in on each side and 40 in at the foot in an empty 120 × 120 in room. The bed frame and other furniture use some of that space.
A 76 × 80 in king leaves only 22 in per side in the same arrangement. Physical floor fit and comfortable access are different questions.
For a 72 × 36 in table with 36 in on all four sides, reserve 144 × 108 in: a 12 × 9 ft rectangle. At 42 in clearance, that becomes 156 × 120 in, or 13 × 10 ft.
Seating capacity also depends on chair width, table legs and usable edge space. A table footprint alone cannot promise a seat count.
Understand your result
A rectangular end face carried square to the opening needs both dimensions to clear. For an 84 × 30 × 34 in box carried lengthwise through a 32 × 80 in clear opening, a 30 × 34 in end face leaves 2 in across the width and 46 in vertically.
That establishes clearance at the opening in that pose. It does not establish enough room to bring the 84-inch length into position or turn afterward.
A 40 × 40 in rigid square has a diagonal of about 56.6 in—less than the 86.2 in diagonal of a 32 × 80 in opening. Yet rotating that square within the opening’s plane never makes it narrower than 40 in.
For a face with sides a and b rotated by angle θ in the opening plane:
width = a cos θ + b sin θ
height = a sin θ + b cos θ
Both projections must fit at the same angle. Three-dimensional threading and a sofa’s actual profile are different problems. Comparing diagonals, or adding doorway width to ceiling height, does not prove a delivery path.
The planner above adds the clearance to each open side, then checks the resulting rectangle against the room in both orientations.
An 84 × 38 in sofa against a wall, with 36 in on its left, right and front, needs 156 × 74 in. In a 168 × 144 in room, that leaves 12 in across the width and 70 in across the depth beyond the reserved footprint.
Those are total leftover dimensions, not extra clearance guaranteed on every side. Furniture area and reserved walkway area are shown separately.
For an ideal, zero-thickness ladder moving flat around a right-angle corner, the length limit is (A2/3 + B2/3)3/2, where A and B are the corridor widths.
Furniture has thickness. Stairs add slope, railings, landings and headroom. Multiplying the ladder limit by an arbitrary safety percentage is not a validated furniture fit test. Describe the full turn and check the assumptions in the result.
A cabin diagonal answers none of these on its own. Include the door’s position, the approach, and the cabin’s width, depth and height.

| Item | Inches | Centimeters | Measure before moving |
|---|---|---|---|
| Example sofa | 84 × 38 × 34 | 213 × 97 × 86 | Outer back, arms and fixed legs; ask for a delivery drawing. |
| Example loveseat | 60 × 36 × 34 | 152 × 91 × 86 | Removable parts only if confirmed for this model. |
| US queen mattress | 60 × 80 × model thickness | 152 × 203 × model thickness | Frame and packaging add size. Follow the maker’s bending instructions. |
| US king mattress | 76 × 80 × model thickness | 193 × 203 × model thickness | Do not substitute mattress dimensions for the bed frame. |
| Example rigid queen foundation | 60 × 80 × 9 | 152 × 203 × 23 | A rigid frame cannot be assumed to flex; check each split section separately. |
| Example wardrobe | 40 × 22 × 75 | 102 × 56 × 191 | Assembled and flat-packed dimensions can be very different. |

Important disclaimer · Please read carefully
This furniture fit calculator helps estimate whether an item can pass through a measured doorway, staircase, elevator, hallway or other space. Results are guidance only and are not guaranteed to be 100% accurate.
Verify measurements before purchasing or moving furniture, and consult your retailer, delivery provider or a qualified professional where appropriate. Applicable retailer delivery and return policies remain controlling; check them directly with your provider.
Before you measure
They are separate checks. Use the delivery calculator for openings, stairs, elevators and turns. Use the room planner for one rectangular furniture footprint plus clearance in an empty rectangular zone. Passing either check does not establish the other.
The room planner accepts inches or centimeters and converts entered values when you switch units. The delivery calculator accepts dimensions with units written in your question. Always label which measurement belongs to the item and which belongs to the space.
In an empty 120 × 120 in room, a 60 × 80 in queen mattress centered against one wall leaves 30 in per side and 40 in at the foot. A 76 × 80 in king leaves 22 in per side. Add the actual bed frame, nightstands and door swings before deciding whether the layout works.
Start with 36 in from the tabletop edge to the nearest obstruction and test your actual chairs. Try 42–48 in where people pass behind seated guests. A 72 × 36 in table with 36 in on every side needs a 144 × 108 in rectangle, before accounting for other obstacles.
Measure the actual rigid foundation, every stair flight, the landings and the available headroom. Do not assume it can bend like a mattress. A split foundation can make a move easier, but each section still needs its own route check.
Measure a clear rectangular zone within an L-shaped room. For a sectional, enter the full outer footprint including the chaise; this reserves its bounding rectangle and does not reclaim the empty space inside the L. The planner does not combine multiple furniture pieces or verify connected walking paths.
Measure the item’s full width, depth and height, then the door’s usable opening with the door open. Include packaging, handles and other fixed protrusions. Measure the space on both sides of the doorway so you can check whether the item has room to turn. Door width alone cannot establish that the whole move will work.
The nominal door size is not enough to tell. Measure the actual clear width and height, the couch’s outer dimensions, and the approach and exit space. Orientation can change which dimensions need to clear the opening, but tilting also requires sufficient room and headroom. Use the measured opening rather than assuming a standard door guarantees a fit.
Confirm with the manufacturer or retailer whether the sectional separates into modules. If it does, measure each module in its delivery configuration, including fixed connectors, arms and legs. Check every module along the full route. Do not assume a sectional separates or that its legs can be removed.
Results depend directly on the dimensions you provide. Measure critical spaces twice, use the same units throughout, and pay particular attention to the narrowest points in the route. Include packaging if it will stay on during delivery.
A rectangular bounding box is a useful starting point. Measure the widest, tallest and deepest fixed points, including curved arms, protrusions and angled legs. An irregular shape can move differently from its bounding box, so verify tight clearances with your delivery provider.
Interior doors, hallway turns, stair railings, low lighting fixtures, sloped ceilings, baseboards, trim and thresholds are common misses. Also measure the maneuvering room on both sides of an opening.
Real spaces can contain conditions that were not included in the measurements, and safe handling can require more room. ItemFits is a planning aid, not a delivery guarantee. Verify the complete route with your retailer or delivery provider; their delivery and return policies still apply.
