Enter your mattress size and hallway measurements — the app checks straight sections and corner turns for king, queen, full, or twin.
Whether it fits depends on measurements most people get wrong.
Mattress thickness (on edge) vs. hallway width, and mattress length vs. turning space at corners
Item: Queen: 60" × 80" × 10–14" thick. King: 76" × 80" × 10–14" thick
Space: Standard residential hallway: 42–48" wide. Building code minimum: 36" wide
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.
Verdicts are calculated by comparing all 6 item orientations against the space dimensions using verified building code standards. See our methodology

Frequently asked
Yes — this is the standard technique. A queen mattress on its long edge is only 10–14 inches thick, which easily clears any hallway. The challenge is the 80-inch length, which needs ceiling clearance. For low ceilings, tilt the mattress at an angle instead of fully vertical.
01Stand the mattress on edge and pivot it around the inside corner. For foam mattresses, you can bend them slightly at the turn. For innerspring mattresses, you may need to tilt the mattress at varying angles as you navigate the corner. Having two people makes this much easier.
02Yes — all-foam and memory foam mattresses can be folded in half or rolled for short moves without damage. Use ratchet straps to keep it compressed. Do not leave it folded for more than a few hours. Innerspring and hybrid mattresses should not be folded.
03King mattresses (76" wide) are the most problematic — they are wider than most hallways when carried flat. Queen (60"), full (54"), and twin (38") sizes rarely cause straight-section issues when carried on edge. The main challenge for all sizes is navigating hallway corners.
