I have helped enough people return furniture to know that the most common mistake is buying something without measuring first. The second most common mistake is measuring the room but not measuring the doorways. The third is not measuring the stairwell. These things happen at least a few times a month, and they are completely avoidable.
Here is the measurement process we recommend before any significant furniture purchase.
What to measure before you shop
The room:
- Length and width of the room
- Height of any window sills (furniture placed below a window must not exceed this height)
- Height of the ceiling (matters for tall pieces: armoires, bookcases, entertainment walls)
- Location and swing direction of all doors -- note which way each door opens
- Location of electrical outlets (relevant for placement of powered furniture)
- Location of HVAC vents in the floor or wall (do not block these)
The path from the door to the room:
- Width of every doorway the furniture must pass through (measure the opening, not the door itself)
- Height of each doorway
- Any hallways that furniture must navigate (width and length of the turn)
- Stairwell width and ceiling height at the narrowest point (if applicable)
- Elevator dimensions (if applicable -- note most residential elevators are around 36 by 48 inches, which is smaller than many sofas)
Write everything down in a small notebook or phone notes app before you leave home. Memory is not reliable under showroom lighting.
Key measurements for specific furniture types
Sofas and sectionals
The three measurements that matter: overall width, depth (front to back), and the diagonal of the sofa. The diagonal is often more relevant than the width for getting it through doorways -- a 90-inch sofa may fit through a 36-inch doorway if it can be turned diagonally. The standard way to estimate diagonal clearance is (width squared + height squared, square rooted), but the honest answer is: if you are close to the limit, call us and we can help you work through it before you buy.
Sectionals are the hardest pieces to deliver. They often disassemble into sections, but not always. Ask the showroom specifically whether the sectional you are considering breaks apart, and what each section's dimensions are.
Beds
Beyond the room fit, beds often have a challenging delivery path because the headboard is usually the tallest and most rigid part. A tall upholstered headboard that is 65 inches wide may not turn through a standard 80-inch hallway at the angle required. Measure the hallway width and then consider whether the headboard height (which becomes the headboard width during a horizontal carry) fits the turn.
Bed frames usually deliver as separate components (headboard, footboard, rails) which simplifies delivery significantly. Platform beds and upholstered beds with unified structures are harder to maneuver.
Dressers, armoires, and entertainment centers
Width-first delivery: these pieces typically enter doorways by going through with their narrowest dimension first (depth leading, then rotating to place against the wall). For a standard doorway of 32 to 36 inches, the depth of the piece must clear the opening. Most dressers and armoires have depths of 18 to 24 inches, which clears most doorways. The issue arises with armoires that must go upstairs: the combination of height and depth may make the turn at the landing impossible.
Check the door heights, not just the widths, for tall pieces. An armoire that is 79 inches tall needs a doorway that is at least 79 inches high plus clearance to tilt it through at an angle. Most interior doorways are 80 inches high -- which leaves barely an inch of clearance for tipping a piece through. If the armoire is over 78 inches, confirm the delivery path carefully.
The clearance rules once furniture is in the room
Once you have the room dimensions and the furniture dimensions, check these minimum clearances:
- Traffic lanes: 36 inches minimum for a primary path through a room. 24 inches for a secondary path that sees occasional use.
- Dining table chairs: 36 inches from table edge to wall or other furniture when chairs are pushed in. 48 inches is more comfortable if people walk behind seated guests regularly.
- Bed clearance: 24 to 30 inches on the sides of the bed (22 inches minimum if the space is tight). 36 inches at the foot of the bed to allow the dresser drawer to open.
- Sofa and coffee table gap: 14 to 18 inches between the edge of the coffee table and the sofa cushion edge.
- TV stand placement: The center of the TV screen should be at seated eye level when viewed from your primary seating position (roughly 42 to 48 inches from the floor for standard couch height).
A simple process that catches most problems
- Measure the room and sketch a rough floor plan (does not need to be architectural grade -- just proportional).
- Note every door, window, and vent location.
- Measure every doorway and hallway on the delivery path.
- At the showroom, note the dimensions on the tag before asking whether a piece fits. Many tags include height, width, and depth. Verify those dimensions with a tape measure if you are close to the limit.
- Apply the clearance rules to confirm the piece works in the room.
If you bring your measurements to the showroom and tell us what you are working with, we can help you identify pieces that fit and skip the ones that will not before you fall in love with something that will not make it through your hallway.
