As a rule of thumb, one gallon of paint covers approximately 350 to 400 square feet of wall area with a single coat. Our paint calculator subtracts windows and doors to compute exact gallons needed.
Multiply length (ft) × width (ft) × thickness (ft) to get cubic feet, then divide by 27 to convert into cubic yards. Always add 10% for spillage and uneven grade.
For standard square or rectangular layouts, add 10% extra for waste and cuts. For diagonal patterns, herringbone, or rooms with complex angles, add 15% extra.
One roofing square equals 100 square feet of roof surface. Shingles and underlayment are ordered by the square, factoring in roof pitch multiplier.
