Method and assumptions
Figur converts the measurements you enter into area, volume, or material quantity using standard geometry formulas.
- Surfaces and depths are uniform unless you divide the project into separate sections.
- Waste allowance, manufacturer coverage, and package sizes should be checked before purchasing.
- Site conditions and installation requirements can change the final quantity.

Frequently asked questions
Should I subtract doors and windows?
For small openings, keeping them in the estimate provides useful matching and repair material. Subtract only large openings after checking the installer’s and manufacturer’s guidance.
Why is pattern waste important?
A repeating pattern may force each strip to start higher on the roll. Larger repeats, tall walls, and complex layouts need more than the basic allowance.
