How to Calculate Paint Needed
Paint coverage varies by product, surface texture, and number of coats. Using too little leaves uneven coverage; buying too much wastes money. This calculator gives you an accurate estimate based on your room dimensions and paint specifications.
Calculation Steps
- Calculate total wall area: (2 x (length + width)) x ceiling height
- Subtract doors and windows (avg door: 2 m2, window: 1.5 m2)
- Multiply by number of coats (typically 2 for new walls)
- Divide by paint coverage (typically 10–12 m2 per liter)
Example
Room: 4 m x 3.5 m, ceiling 2.5 m, one door, one window, 2 coats.
- Wall area: (2 x (4 + 3.5)) x 2.5 = 37.5 m2
- Less openings: 37.5 - 2 - 1.5 = 34 m2
- For 2 coats: 34 x 2 = 68 m2 coverage needed
- At 10 m2/L: 6.8 liters needed (buy 7–8 L to be safe)
Paint Coverage by Type
| Paint Type | Coverage per Liter |
|---|---|
| Emulsion / Latex | 8–12 m2 |
| Gloss / Satin | 14–16 m2 |
| Primer | 8–10 m2 |
| Masonry paint | 4–6 m2 |
Tips for Accurate Coverage
- Always add 10–15% extra for waste and touch-ups
- Porous or rough surfaces require 20–30% more paint
- Dark colors covering light walls may need 3 coats
- Keep leftover paint in an airtight container for future touch-ups
