How Much Paint Does a 10x8 Room Need?
A 10x8 room with 8ft ceilings has 288 square feet of gross wall area. After deducting a door and one window, the paintable area is roughly 253 square feet. At 400 square feet per gallon and two coats, that is only 1.26 gallons — one gallon covers this room for two coats with just enough remaining for touch-ups.
The 10x8 ceiling is just 80 square feet. One quart of ceiling paint is comfortably enough for two coats.
In litres, a 10x8 room needs just 3.8 to 5 litres for two wall coats. A single 5 litre tin is more than enough and gives you a useful amount left over for touch-ups.

Tips for Painting a 10x8 Room
One gallon is genuinely enough for two wall coats in a 10x8 room — one of the few room sizes where this is true.
Use a satin or eggshell finish — the slight sheen reflects light and makes this small room feel brighter and more open than flat paint would.
Light colours are best for small rooms — soft whites, pale greys, and warm creams maximize the sense of space.
A 4-inch foam roller is ideal for the smaller wall sections in a 10x8 room — it gives better control than a full 9-inch roller in tight spaces.
Ventilate the room well throughout painting — small spaces accumulate paint fumes quickly even with low-VOC products.
