Question

Is the square footage in Squaremetry accurate?

Yes, the square footage is accurate: the math is exact, as Squaremetry keeps full precision and rounds only the totals you see, to the nearest square foot or 0.1 m². How close the result is to your home depends on your measurements and, when you trace, on the scale you set. The rules of the standard come with a version, and every number shows its reason.

In short: Is the square footage in Squaremetry accurate?

  • Exact math, rounded only at the end
  • The rule behind every room, with the version of the rule set
  • Rules tested against the worked examples in the standard
  • Where every length comes from: measured, laser, drawing or assumed

Do you round the areas?

We keep full precision while you draw and round only the totals you see, to the nearest square foot or 0.1 m².

Who checks the rules?

The Squaremetry team writes each rule from the official text, in its own words, and tests it against the worked examples in the standard. Each rule has a version and a date.

Which standard should I use?

For a listing or an appraisal in the US, ANSI Z765. In the Netherlands, the meetinstructie, based on NEN 2580. For your own planning, the sum of the rooms is enough.
