Formula and methodology
Formula: exact = area*coats/coverage; buy = ceil(exact).
Total area times coats divided by label coverage gives exact gallons; buy whole gallons rounded up since paint sells by the can.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Paintable area — sq ft; Walls minus doors and windows.; minimum 1.0E-6; maximum 1000000000
- Coats — minimum 1; maximum 10
- Coverage per gallon — sq ft/gal; From the paint label; enter your product's figure.; minimum 1; maximum 100000
Worked example
| Input | Value |
|---|---|
| Paintable area | 400 |
| Coats | 2 |
| Coverage per gallon | 350 |
2.29 gal exact; buy 3 gallons.
