## How It Calculates

- **Formula:** Liters = area × coats ÷ coverage

**Inputs:**

- Paintable area
- Coats
- Coverage (m²/L)

All calculation runs locally in your browser; results update as you type and include the substituted working.

## Stop Guessing at the Paint Store

A liter of emulsion covers roughly 10 m² per coat, but rooms, coats and surfaces differ. AiLoveKit's **paint calculator** turns your measured area, coat count and can coverage into exact liters for finish paint and primer - so you buy enough without carting home surplus tins.

## Estimating Wall Area Fast

- **Room rule of thumb** - floor area × 3 for walls plus ceiling.

- **Deduct openings** - subtract doors and large windows.

- **New plaster** - always budget a primer coat.

## Frequently Asked Questions

**How do I measure paintable area?**

Multiply each wall length by its height, add ceilings, and subtract large openings. Quick rule: room floor area × 3 approximates walls plus ceiling.

**Why two coats?**

One coat rarely hides the old color evenly. Two coats give uniform finish and durability; going over a dark color may need three.

**Does surface texture matter?**

Yes - rough plaster and unpainted putty absorb more paint, reducing effective coverage by up to 20%. Primer helps on new surfaces.
