Frequently asked questions

Why calculate in feet on a metric-first site?

"Square footage" is a specific, commonly searched term (especially in real estate) that conventionally means the area in square feet — this calculator gives that figure directly, alongside the metric equivalent.

I have my room's dimensions in meters — is there a metric version?

Yes — see the Room Area Calculator, which takes length and width directly in meters.

How do I convert an odd-shaped room's area?

Split the room into rectangular sections, calculate each one's area separately, and add them together.
