About Will It Fit?

Will It Fit?is a free visual tool that shows whether a given mattress size fits in a bedroom of a given size — to scale, with the walking clearance you'd actually have around the bed. We built it because most answers to "will a king fit in a 10×10 room?" are buried in text articles; a quick visual is far clearer.

How it works

We use standard US mattress dimensions and add a typical bed-frame allowance (about 3 inches around the mattress). The bed is placed against the headboard wall and centered, and we measure the clearance on each side and at the foot. We flag fit against the common interior-design guideline of at least 24 inches of walkway on the sides you use to get in and out.

Limitations

These are planning estimates. Real-world fit also depends on door and closet swings, windows, radiators, and outlets, and on your specific bed frame, which this tool doesn't model. Always measure your actual room and furniture before buying.
