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

And as for as wall painting is concerned we need 2 coats of paint for better finishing. Most of the paint covers a 100 square foot area or less for 2 coats with 1 liter of paint approximately.

So, let’s move to the next part and discuss How much paint is needed for a 12×12 room in detail.

The size of the room- 12 ft x 12 ft

Let’s consider the height of the room-10ft

Area of one wall- 12ft x 10 ft=120 sq. ft

Area of 4 walls- 120 sq . ft x 4=480 sq. ft

Area of the ceiling or roof- 12 ft x 12 ft= 144 sq. ft

Total area= Area of 4 walls+Area of the ceiling or roof

ie: 480 sq. ft+144 sq. ft= 624 sq. ft

The room must have a door and the mostly the size of the door is -7 ft x 3 ft= 21 sq. ft

Let’s consider the room has 1 window and the size of the window (in general) is- 4 ft x 4 ft= 16 sq. ft

The total area of the door and the window is- 21 sq. ft + 16 sq. ft= 37 sq. ft

So, the actual area to be painted is- (Total area – the area of the door and the window)

ie: 624 sq. ft-37 sq. ft= 587 sq. ft (the actual area to be painted in a 12×12 room)

As discussed above for fresh painting 1-liter covers 100 sq. ft area in approx.

Hence the paint needed for a 12×12 room is 587 sq. ft ÷ 100 sq. ft= 5.87 liters or 6 liters for 2coats for fresh painting approximately.

And the paint needed for a 12×12 room for repainting (same as the previous color) is 3.5 liter approximately.
