Measure the furniture's final location and the entire delivery route before you buy, because an item can fit comfortably in the room and still be too large for a doorway, hallway, stairwell, or elevator.
Start with the product dimensions, then walk the same path the delivery team will use. Record the narrowest opening, tightest turn, and lowest overhead clearance along the way.
What should you measure before buying furniture?
| Area | Measurements to record | What can reduce the usable space |
|---|---|---|
| Furniture | Overall width, depth, and height; diagonal depth when the seller provides it | Packaging, attached legs, arms, hardware, or moving parts |
| Final room | Available floor space, ceiling height, and walking clearance | Baseboards, vents, outlets, doors, existing furniture, and moving parts |
| Doorways | Clear width and height with each door fully open | Handles, hinges, trim, security screens, and fixed thresholds |
| Hallways and turns | Narrowest width, ceiling height, and space on both sides of every turn | Railings, light fixtures, wall corners, and items that cannot be moved |
| Stairs and elevator | Stair width, landing size, elevator door opening, and inside cab dimensions | Handrails, low ceilings, call panels, and doors that do not open completely |
Check the item as well as the room
Different types of furniture create different delivery problems. Measure the exact model and configuration you plan to order.
- Sofas and sectionals: Check the arms, back height, diagonal depth, removable legs, and the orientation of every sectional piece.
- Dining tables: Find out whether the top, leaves, or base arrive separately. Measure the assembled table for the room and the largest individual piece for delivery.
- Beds and mattresses: Measure the longest frame component and the mattress. A rigid foundation may need more turning room than a flexible mattress.
- Dressers, cabinets, and bookcases: Check the height, depth, and longest diagonal. Tall case goods need enough ceiling and floor space to move from a tilted position to upright.
- Recliners and adjustable furniture: Include the full open position, nearby wall clearance, power cord location, and any removable backs or bases.
How to check the delivery path
- Confirm the product dimensions. Use the exact size, configuration, and variant you plan to order.
- Ask about delivery dimensions. The carton can be larger than the assembled furniture. Ask which parts can be removed or delivered separately.
- Measure the clear doorway opening. Measure the space the item can actually pass through with the door open. Include handles, hinges, trim, and anything else that projects into the opening.
- Follow the route from the truck to the room. Check gates, entry doors, hallways, corners, stairs, landings, and the final doorway.
- Check every turn. A doorway may be wide enough on its own while the wall or railing opposite it leaves too little room to rotate the item.
- Find the tightest point. Share close measurements with the retailer before ordering and ask whether the furniture can be delivered through that route.
Will the furniture work in the room?
Mark the full footprint on the floor with painter's tape. Leave room to walk, open doors and drawers, pull out dining chairs, and use any reclining or adjustable parts. For sectionals and modular furniture, mark each piece in its intended position. Check the product orientation so a chaise, return, or corner unit faces the correct direction.
Can you measure a room with your phone?
Yes. A phone measurement app can help you make a quick room plan and record straight edges. Apple's Measure app can detect rectangular objects or let you set the start and end points yourself. On supported devices, edge guides can make it easier to measure furniture and other straight surfaces. Apple states that these measurements are approximate, so use a tape measure to confirm tight doorways and delivery clearances before placing an order. See Apple's Measure app instructions.
A LiDAR-equipped phone or tablet can scan the shape of a room more quickly than measuring each wall by hand. Scan from several positions, keep the camera pointed at clear edges, and save screenshots or a floor plan for reference. LiDAR may miss small obstructions or the extra space needed to tilt and turn a large item. Confirm door hardware, trim, packaging, and narrow clearances with a physical tape measure.
Online furniture buying checklist
- Exact product width, depth, and height
- Carton or delivery dimensions, when available
- Largest component if the item arrives in separate pieces
- Removable legs, backs, drawers, shelves, bases, or connectors
- Every doorway's clear width and height
- Narrow hallways, sharp corners, stairs, and landings
- Elevator door width and interior dimensions
- Final placement, walking space, and operating clearance
- Building delivery rules, reservation times, and elevator protection requirements
Frequently asked questions
Does furniture have to be narrower than the doorway?
Not always. Some items can pass through upright, on their side, or at an angle. The answer depends on the item's width, depth, height, shape, removable parts, and the turning space around the door. Ask the retailer for delivery guidance when the measurements are close.
Do product dimensions include the packaging?
Product dimensions generally describe the assembled furniture. Packaging can add width, depth, or height, so request carton or delivery measurements when they are available.
Is a phone measurement accurate enough to order furniture?
Use the phone scan to plan the room and catch obvious problems. Confirm narrow openings and close clearances with a physical tape measure before ordering.
