calculatorYou can use our Paint Calculator to ESTIMATE how many Gallons of Paint you will need for a particular job (for each coat of Paint). Type in the required demensions, and type in how many Square Feet per Gallon the Paint is supposed to yield (we recommend using a conservative value of 300 sq. ft. per Gallon). If you have a Door or Window or both on any one or two of the Walls, type in the approximate dimensions of them also... NEXT click the "Calculate" button for your results!

NOTE: For rough surfaces like Block, Brick or Stucco, use 20% LESS for the Coverage Value ... so 300 - (.2 X 300) = 240 sq. ft. per Gallon!

NOTE: To Calculate requirements for a CEILING, use the Calculator again and type in the dimensions for the CEILING into the WALL dimension's Width and Height boxes!

Keep in mind that our Calculator presents only an Approximate Value, and of course it is always WISE to buy a little MORE Paint than you expect to use!!!
