How to Estimate DIY Projects

Calculating Concrete

Concrete is measured in Cubic Yards. One cubic yard is 27 cubic feet. The formula is:
(Length x Width x Depth in feet) ÷ 27.

Tip: Always order 10% more than you think you need to account for spillage and uneven ground.

Calculating Paint

One gallon of paint typically covers 350 to 400 square feet with one coat. To get an accurate number, you must subtract non-paintable areas:

Standard Door: Subtract ~20 sq ft.
Standard Window: Subtract ~15 sq ft.
