Coat & Measure helps turn room measurements into a practical starting point for your shopping list. The calculators are free, require no account, and show the assumptions behind their results.
Practical, transparent estimates
We calculate paint from surface area and coats, flooring from area and box coverage, and wallpaper from full-height strips. You supply product coverage and prices because every project and retailer is different.
These are planning tools, not professional surveys. Check the label, installation instructions, and actual room conditions before buying.
