How much paint do you need?
Enter the room’s length, width and height, then doors and windows. RoomFit estimates wall area, applies coats and a little extra, and suggests a can size to buy. In the iOS app you can also mark a wall in AR and calculate from that surface.
You need
8.8 L
Buy 10 L
39.8 m² wall area · 2 coats · 10% extra included
What the estimate includes
Walls only: 2 × (length + width) × height, minus doors and windows. Default coverage is 10 m² per litre, two coats, and 10% extra. A 4.5 × 3.8 × 2.6 m room with one door and one window comes out to about 8.8 L — so buy 10 L.
Paint brands, colours and surfaces vary. Treat this as a planning number, then confirm with the tin in your hand.

Questions, answered.
How much paint do I need for a room?
RoomFit estimates wall area from length, width and height, subtracts doors and windows, then applies coats, coverage and a little extra. A 4.5 × 3.8 × 2.6 m room with one door and one window is about 8.8 L — so buy 10 L.
Can I measure the wall with AR instead of typing dimensions?
Yes, in the RoomFit iOS app. You can mark a wall in AR and RoomFit uses that surface to estimate paint. It is still a planning aid — confirm coverage with the tin before you buy.
Why is this only an estimate?
Coverage varies by brand, colour, surface and how you apply the paint. Confirm can sizes with the retailer and keep a little extra for touch-ups.
