Enter your mattress size and hallway corner measurements — the app calculates whether you can bend or pivot the mattress around the turn.
Whether it fits depends on measurements most people get wrong.
Mattress width (on edge) and length vs. corridor widths at the turn
Item: Twin: 38" × 75". Full: 54" × 75". Queen: 60" × 80". King: 76" × 80"
Space: Standard hallway corner: 42–48" wide per corridor. Building code minimum: 36" per corridor
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

Standard sizes say it works — but your measurements are what matter.
When the hallway is 36 inches and the furniture is 34, you have 1 inch per side. Here's how professionals move large items through tight corridors without damage.
A 36-inch hallway doesn't mean 36 inches of turning space. At corners, the geometry shrinks dramatically. Here's how turning radius actually works.

Multi-step guides for real-world moves
Twin (38" × 75") and full (54" × 75") mattresses fit around most hallway corners when stood on edge — they are narrow enough to pivot in 36–42" corridors. Queen (60" × 80") mattresses require 42"+ corridors and careful angling. King (76" × 80") mattresses are the hardest — they often need 48"+ corridors or must be bent/compressed to clear the turn.
Memory foam and all-foam mattresses can bend 15–20° without damage, which significantly helps at tight corners. Innerspring and hybrid mattresses bend less (5–10°) and risk spring damage if forced. Never fold a mattress more than 30° or leave it bent for more than a few minutes. Use ratchet straps to hold the bend temporarily.
Yes — always stand the mattress on its long edge for corner navigation. This makes the mattress thickness (8–14") the dimension facing the wall, not the width (38–76"). On edge, even a queen mattress only needs 14" of pivot clearance plus the 80" length to swing through.
Compressed mattress-in-a-box packaging (typically 19" × 19" × 42–45") fits through any hallway corner easily. If you are buying new and have a tight hallway, a bed-in-a-box eliminates the navigation problem entirely. The compressed roll weighs 60–100 lbs depending on size.
