Squaremetry is an online floor plan and measuring tool. You draw a floor plan in your browser, without an account, and every room shows its area by the measuring standard of your country (ANSI Z765, NEN 2580, WoFlV, loi Carrez, RICS). The same model shows the home in 3D and exports a PDF. Squaremetry is based in the Netherlands.
Start with the floor plan maker, see how we calculate every number, or read the ANSI Z765 square footage rules in our own words. Coming from another floor plan app? See what changes when you switch.
HOW IT WORKS
In three steps. Type what you measured, and the plan and the numbers follow.
Or trace a photo or PDF of a floor plan.
Every room and floor, with what counts and what doesn’t.
Or a square footage report with the ANSI calculation.
Quick answers
Multiply the length by the width in feet. Three sizes people ask about most:
144 sq ft
12 × 12 ft = 144 sq ft, or 13.4 m². A bedroom with a queen bed.
400 sq ft
20 × 20 ft = 400 sq ft, or 37.2 m². A two-car garage.
1,200 sq ft
30 × 40 ft = 1,200 sq ft, or 111.5 m². A small house or a large garage.
WHAT YOU GET
Both come from the same measurements, so the plan and the report always agree.
Room names, dimensions and the total, ready for your listing or your contractor.
