How Much Paint Do I Need for a Room?

Room dimensions set the wall area, doors and windows are deducted, coats multiply the paintable area, and coverage per liter converts it to liters. Larger rooms, more coats and thirstier surfaces all raise the quantity.

How to Calculate Paint Required

Wall Area = 2 × (Length + Width) × Height

Paint Required = Paint Area × Coats ÷ Coverage per Liter

Deduct doors and windows, then add ~10% wastage on top.

How Much Does It Cost to Paint a House in Nepal?

Total cost depends on paint brand and type, surface condition, coats, area, primer and labor — there is no fixed national price, so this calculator estimates material quantity and cost from your own inputs.

Before You Buy Paint

  • Check the manufacturer's stated coverage.
  • Account for the surface condition.
  • New plaster or highly absorbent surfaces may require primer.
  • Dark-to-light color changes may require additional coats.
  • Keep a small amount of leftover paint for future touch-ups.
  • Actual consumption can vary from the calculator estimate.

Frequently Asked Questions

How much paint is needed for a 10×12 room?

It depends on height, openings, coats and coverage — but as an example, a 12×10 ft room with 10 ft walls, 1 door, 2 windows, 2 coats at 120 sq ft/L needs about 7.1 liters including wastage. Enter your exact room above.

How do I calculate wall paint area?

Wall area = 2 × (length + width) × height, all in feet. Measure each wall if the room is not rectangular, add them up, then subtract doors and windows.

Should I subtract doors and windows?

Yes, for an accurate estimate. Doors and windows are not painted, so deducting them avoids overbuying. Use “Skip doors & windows” only for a rough upper-bound figure.

How many coats of paint should I use?

Two coats are commonly used for better coverage, but actual requirements depend on the paint, surface condition and color change — dark-to-light changes may need an extra coat.

How much area does 1 liter of paint cover?

It varies by product — 120 sq ft/L is a common planning figure, but always check the manufacturer’s label for your chosen paint and surface.

New plaster or highly absorbent surfaces usually benefit from primer for adhesion and even finish. Enable the primer option above to estimate primer quantity and cost separately.
