A 30-inch door is common for bedrooms. Here's whether a queen mattress will clear it.
Whether it fits depends on measurements most people get wrong.
Mattress thickness (9–14") vs. 30" door clear opening (28–28.5")
Item: Queen mattress: 60" W × 80" L × 9–14" thick
Space: 30-inch door: 28–28.5" clear 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.
Verdicts are calculated by comparing all 6 item orientations against the space dimensions using verified building code standards. See our methodology

1 inch can be the difference between fitting and getting stuck.
“Checked my mattress before ordering. Tight fit, but it worked with the door removed.” — Online shopper
Measurements verified by the ItemFits engineering team · Based on IRC R311.2, IBC Chapter 10, ADA 404 · Our methodology
Standard sizes say it works — but your measurements are what matter.
On its side, a queen (9–14" thick) has 14–19" of clearance in a 30" door opening. This is more than enough — mattresses are never a tight fit through doors on their side.
All-foam queens can be folded or rolled without damage. Innerspring and hybrid queens should not be folded. But folding isn't needed — on its side, the thickness easily clears a 30" door.
The 80" length is the challenge at turns. Tilt the mattress diagonally and feed one end through first. You need at least 36" of hallway width to navigate a 90° turn with an 80" mattress.
