About SqftMeter

SqftMeter is a small, independent website that makes free area calculators for homeowners, renters, DIYers and anyone planning a project. We built it because most calculator sites are slow, cluttered and hard to use on a phone, and because measuring a real room usually means more than one simple rectangle.

What we offer

• Calculators for square footage, rooms, whole houses, flooring, square yards, acreage and square metres.
• Guides that explain how to measure correctly, written in plain English.

How our calculators work

Every calculation runs entirely in your browser. Nothing you type is sent to us or stored on our servers. The share link you can copy simply puts your numbers into the page address, so only people you send it to can see them.

We use standard geometric formulas and exact conversion factors (1 foot = 0.3048 metres; 1 acre = 43,560 square feet). Each calculator shows the formula and your own numbers, so you can check the working.

Accuracy

We test every calculator against hand-worked examples, but results can only be as good as the measurements you enter. For purchases, sales, legal boundaries or appraisals, please confirm figures with a qualified professional. See our terms of use.

Advertising

SqftMeter is free to use and is supported by advertising. Ads are clearly labelled and kept away from the calculator inputs. Read our privacy policy to learn how ads and cookies work on this site.
