What is the first measurement to check for a sleeper sofa?

Start with the largest rigid dimension, then check the narrowest opening or turning point. A large item can have enough final space but still fail at the route into that space.

Should I measure with packaging or padding included?

Yes. Add the package, moving blanket, mattress bag, appliance dolly, or protective padding when that is how the item will actually be moved.

Whether it fits depends on measurements most people get wrong.

Key Measurement

Item dimensions vs. usable up stairs dimensions

Standard Dimensions

Item: Varies by model; measure the actual item.

Space: Varies by space; measure the usable interior and opening.

Actual clear openings are usually 1–2″ smaller than the labeled size.

Your exact dimensions probably aren't "standard." Small measurement errors cause big problems — 1 inch can be the difference between fitting and getting stuck.

“Wish I'd used this before trying to force a fridge up the stairs.” — Lesson learned

Measure smart

What to measure.

Four numbers decide nearly every fit check. Get these right and the rest follows.

01Measure the sleeper sofa length, width, height, and any protruding hardware or packaging.
02Measure the usable up stairs dimensions at the narrowest point, not the nominal size.
03Check the opening, turn, or access path that the item must pass through before it reaches the final position.
04Leave practical clearance for hands, padding, door swing, walking paths, or packing material.

Don't make these

Common mistakes.

Most “it didn't fit” stories trace back to one of these oversights.

⚠Using catalog dimensions without measuring the actual item, frame, handles, legs, or packaging.
⚠Checking only volume or floor area while ignoring the opening and turn required to place the item.
⚠Forgetting that padding, blankets, boxes, and dollies add thickness during a real move.
