How to Use This Calculator

Enter Total trim linear ft, Average trim width (in), and Number of coats.
Set Finish type (0=paint, 1=stain, 2=clear), Cost per quart ($), and Primer needed? (0=no, 1=yes).
Adjust Sanding grit cycles as needed.
Review the Finish needed (quarts) result.
Use Surface area (sq ft) and Finish needed (gallons) to inform your decision.

How the result changes with Total trim linear ft

Total trim linear ft: Combined linear feet of all trim to finish (baseboard, casing, crown, etc.).
Average trim width (in): Average face width of your trim profiles.
Number of coats: Number of finish coats to apply.
Finish type (0=paint, 1=stain, 2=clear): 0 = Paint, 1 = Stain, 2 = Clear coat / polyurethane.
Cost per quart ($): Price per quart of your chosen finish.
Primer needed? (0=no, 1=yes): 1 if primer coat is needed (recommended for paint on bare wood).
Sanding grit cycles: Number of sanding passes (e.g., 2 = 120-grit then 220-grit).

Surface area (sq ft): Total trim surface area to be finished.
Finish needed (quarts): Quarts of paint, stain, or clear coat for all coats.
Finish needed (gallons): Same quantity in gallons for easier purchasing.
Primer (quarts): Quarts of primer needed (if selected).
Sandpaper sheets: Estimated sandpaper sheets for all sanding passes.
Finish cost: Estimated cost for finish and primer.

Identify Input Parameters
4 parameters
Total trim linear ft = 200, Average trim width (in) = 3.5, Number of coats = 2, Finish type (0=paint, 1=stain, 2=clear) = 0 = 7 input(s) provided
Calculate Finish needed
Finish needed = quartsPerCoat * coats
1.34 = 1.34
Calculate Surface area
Surface area = totalLinearFt * trimWidthFt
58.33 = 58.33
Calculate Finish needed
Finish needed = totalFinishQuarts / 4
0.34 = 0.34
