How much paint do I need for a 10×10 room with 8 ft ceilings?
For a 10×10 room with 8 ft ceilings, 1 door(s) and 1 window(s), you need approximately 2 gallons of paint for 2 coat(s). The total paintable wall area after subtracting openings is 287.00 square feet. For 2 coat(s), that's 574.00 square feet of coverage needed. Use our interactive Paint Calculator to customize your room dimensions and compare paint types.
How do you calculate paint for a 10×10 room?
The formula is: Wall Area = 2 × (Length + Width) × Height, minus openings. For your 10×10 room: perimeter = 2 × (10 + 10) = 40.00 ft. Gross wall area = 40.00 × 8 = 320.00 sq ft. Subtract 21 sq ft for 1 door(s) and 12 sq ft for 1 window(s) to get 287.00 sq ft net. Divide by 350 (sq ft per gallon) and multiply by 2 coat(s): 574.00 ÷ 350 = 2 gallons.
How many gallons for 1 coat vs 2 coats in a 10×10 room?
For a 10×10 room, one coat of paint requires 1 gallon(s). For two coats, you would need 2 gallons total. Most rooms require two coats for even coverage, especially when painting over darker colors or using lighter shades. Dark colors like deep reds or blues may need three coats. Use our calculator to adjust coats and compare total paint needed.
Do I need to paint the ceiling in a 10×10 room?
The ceiling area for a 10×10 room is 100.00 square feet. Ceiling paint is typically sold separately and a gallon covers 350-400 square feet. For this room, one gallon of ceiling paint should be sufficient for one or two coats. Using a slightly different sheen (eggshell or flat) for the ceiling compared to the walls (satin or semi-gloss) is standard practice. Use our Paint Calculator to include ceiling paint in your estimate.
