Wall-area calculator from a floor plan

For renovation companies, estimators, and site supervisors: calculate wallpaper, plaster, and paint without copying dimensions from a plan into a spreadsheet by hand.

Vs manual count: difference ≈ 1–2%
Format: online + CSV

Wall-area calculator: project totals and estimate table with a real-project preset — Online version with a real-project preset and CSV export.

What I built

A calculator: enter rooms and openings — get wall area with material allowance. There is an online version with a real-project preset and CSV export. A newer version reads a PDF plan, finds rooms and contours on its own; tricky spots can be fixed by hand.

What you get

Wall area in m² accounting for openings and reveals
Material allowance
CSV export for Excel
A separate version — calculation from a PDF plan, verified on a real project
