All sheds need to be painted occasionally in order to protect them from the elements. Painting a shed is easy enough to do, but it can be hard to figure out how much paint to buy to do the job. Most experts recommend buying one gallon of paint to cover up to 400 square feet of surface. Using this recommendation, along with the length and width of your shed, allows us to calculate how many gallons of paint you will need.

If your shed has trim, estimate the amount of paint you’ll need by determining the length of total trim. If the average trim width is six inches, multiply the total trim length by 0.5 feet.  To estimate the gutter, determine the total length of the gutter.  One linear foot of gutter approximates one square foot.
