What this tool does

Check whether a couch fits through a doorway with a simplified 2D pivot model of its end profile. SIMPLIFIED 2D MODEL: real fits also depend on hallway width, ceiling height, turns at the door, removable legs/feet and cushions. A 'fits on the pivot' result means it is worth attempting with care, not a guarantee.

How to use the Couch Fit Calculator

  1. Enter or select door opening width in in.
  2. Enter or select door opening height in in.
  3. Enter or select couch depth (front to back) in in.
  4. Enter or select couch height (floor to top of back) in in.
  5. Enter or select couch length in in.
  6. Read the calculated result; change any measurement to compare alternatives.

Formula

Simplified 2D pivot model: the couch end profile (depth × height) rotates in the plane of the doorway. Straight fit needs depth ≤ door width and height ≤ door height; pivot fit needs the profile diagonal √(depth² + height²) ≤ door height and the shorter profile side ≤ door width.
doorWidth
Door opening width (in, before metric conversion)
doorHeight
Door opening height (in, before metric conversion)
depth
Couch depth (front to back) (in, before metric conversion)
height
Couch height (floor to top of back) (in, before metric conversion)
length
Couch length (in, before metric conversion)

SIMPLIFIED 2D MODEL: real fits also depend on hallway width, ceiling height, turns at the door, removable legs/feet and cushions. A 'fits on the pivot' result means it is worth attempting with care, not a guarantee.

Worked example

For couch fit calculator, the following measurements illustrate the exact method: Door opening width: 32; Door opening height: 80; Couch depth (front to back): 36; Couch height (floor to top of back): 38; Couch length: 84.

Inputs

  • Door opening width32 in
  • Door opening height80 in
  • Couch depth (front to back)36 in
  • Couch height (floor to top of back)38 in
  • Couch length84 in

Result

  • VerdictUnlikely to fit this doorway (2D model)
  • Couch profile diagonal52.35 in
  • Pivot clearance (door height − diagonal)27.65 in
  • Straight-in depth clearance-4 in

Results explained

Verdict
Verdict from the formula above. SIMPLIFIED 2D MODEL: real fits also depend on hallway width, ceiling height, turns at the door, removable legs/feet and cushions. A 'fits on the pivot' result means it is worth attempting with care, not a guarantee.
Couch profile diagonal
Couch profile diagonal from the formula above, expressed in in before metric conversion. SIMPLIFIED 2D MODEL: real fits also depend on hallway width, ceiling height, turns at the door, removable legs/feet and cushions. A 'fits on the pivot' result means it is worth attempting with care, not a guarantee.
Pivot clearance (door height − diagonal)
Pivot clearance (door height − diagonal) from the formula above, expressed in in before metric conversion. SIMPLIFIED 2D MODEL: real fits also depend on hallway width, ceiling height, turns at the door, removable legs/feet and cushions. A 'fits on the pivot' result means it is worth attempting with care, not a guarantee.
Straight-in depth clearance
Straight-in depth clearance from the formula above, expressed in in before metric conversion. SIMPLIFIED 2D MODEL: real fits also depend on hallway width, ceiling height, turns at the door, removable legs/feet and cushions. A 'fits on the pivot' result means it is worth attempting with care, not a guarantee.

Frequently asked questions

If its depth is under 32 in and its back height under the door height, it goes straight in. Deeper couches can still pivot if the diagonal of the depth × height profile is shorter than the door height — this tool checks exactly that.

Stand the couch on end near the door and rotate ('pivot') it through the opening so the back and seat pass at an angle. The limiting measurement becomes the diagonal of the couch's end profile versus the door height.

Door width and height (frame to frame, not the slab), couch length, depth and back height with legs removed, plus hallway width and ceiling height at any turn.

Remove the couch feet/legs, take cushions off, remove the door from its hinges (gains about an inch), and take off door stops. Each is cheaper than a failed delivery.

If the profile diagonal exceeds the door height and the couch cannot stand up in the hallway (low ceiling or tight turn), look at windows, balcony hoists or a different piece — forcing it damages both couch and frame.
