Run a check
Will it fit?
On moving day
Moving tips.
- 01A king mattress is unwieldy due to size, not weight — use mattress handles or straps for a better grip.
- 02Always use a mattress bag. King mattresses collect dirt easily due to their large surface area.
- 03For tight stairways, carry the mattress lengthwise on its side with one person above and one below.
- 04Split king mattresses (two Twin XLs) are much easier to move — check if yours separates.
Measure smart
What to measure.
Four numbers decide nearly every fit check. Get these right and the rest follows.
- 01Your king mattress's width, height, and depth at their widest points — including handles, feet, and any fixed trim. A standard king mattress runs about 80" deep, but compact and oversized versions vary by several inches, so measure yours rather than trusting the label.
- 02The smallest face of the king mattress and its diagonal. Many pieces only clear a tight opening when tilted, and that turns on the diagonal, not the flat width.
- 03Every opening on the route, not just the destination room — the door, the hallway and any turn, the stair width, and the elevator. "Through a Door" is the check people run most for a king mattress, but the tightest point on the whole path is what decides the move.
- 04The king mattress's weight, especially for solid-wood pieces, so you know how many people and what equipment the move needs.
Don't make these
Common mistakes.
Most “it didn't fit” stories trace back to one of these oversights.
- ⚠Measuring the room the king mattress is headed for but forgetting the doorway, hallway turn, or stair landing it has to pass through first.
- ⚠Ignoring the diagonal. A king mattress that looks too wide for a door often clears it tilted — but only if you measured the diagonal, not the flat face.
- ⚠Leaving legs, doors, drawers, or cushions on. Removing them often saves the few inches that decide the fit for a king mattress.
- ⚠Assuming a published size matches your exact king mattress. Apartment, compact, and oversized models differ by several inches.
Frequently asked
Questions we keep getting.
Will a king mattress fit through a doorway?
Yes. Even though a king mattress is 76 inches wide, it is only 10-14 inches thick. When stood on its side, it easily passes through standard 32-36 inch doorways.
01Can you fit a king mattress in a pickup truck?
A king mattress (76 x 80 inches) fits in a full-size pickup bed (typically 79 x 66 inches for a 6.5-foot bed) with some overhang. It fits completely flat in an 8-foot bed.
02What is the difference between a king and California king?
A standard king is 76 x 80 inches (wider). A California king is 72 x 84 inches (narrower but longer). The Cal king is better for tall individuals but has less total area.
03How heavy is a king mattress?
A king mattress weighs 90-200 pounds depending on the type. This is 30-50 pounds heavier than the equivalent queen. Always use two people to move a king mattress.
