Trim and Baseboard Paint Estimate
Estimate trim paint from linear feet, trim width, doors, windows, coats, and paint coverage.
Measure linear feet
Measure baseboards, door casing, window casing, crown molding, and other trim separately.
Convert width to feet
A 4 inch baseboard is 0.33 feet wide. Multiply linear feet by width in feet for square footage.
Account for sides and profiles
Detailed trim profiles can use more paint than a flat board of the same face width.
Use smaller containers
Trim paint is often bought in quarts or gallons depending on the total linear feet.
FAQ
Do doors count as trim?
Door slabs are usually estimated separately from trim casing.
How many coats for trim?
Two coats are common, especially with semi-gloss paint.
Should I sand before painting trim?
Light sanding helps adhesion on glossy or previously painted trim.
