Paint Calculator
Trusted baseline: 1 liter covers about 9.2 sq m per coat (about 10.8 L per 100 sq m).
Measure wall area, subtract major openings, and adjust coats to get a practical estimate for liters, gallons, and bucket counts.
Openings on main walls (optional)
Add each window or door as width × height (m × m). We subtract that area from the main wall group. Trim and frames still need paint—leave a buffer if you want extra material.
Additional wall sections
Use this when some walls have different sizes.
No extra walls added yet.
