HOW TO CALCULATE

Step 1:
Measure the length, width, and wall height of your room.

Step 2:
Multiply the length by the wall height and multiply by 2.

Step 3:
Multiply the width by the wall height and multiply by 2.

Step 4:
Add the two totals together.

Formula:

(Length × Height × 2) + (Width × Height × 2)

Step 5:
Multiply the total wall area by the number of coats.

Step 6:
Divide the result by 350.

Most paint covers approximately 350 square feet per gallon.

EXAMPLE

Room Length = 12 ft

Room Width = 15 ft

Wall Height = 8 ft

Coats = 2

Calculation:

(12 × 8 × 2) = 192 sq ft

(15 × 8 × 2) = 240 sq ft

Total Wall Area = 432 sq ft

432 × 2 coats = 864 sq ft

864 ÷ 350 = 2.47 gallons

Result:

Recommended Purchase = 3 Gallons of Paint

NOTE

Always round up to the next full gallon.

Buy a little extra paint for touch-ups and future repairs.
