Formula or decision rule
sum of (piece width × height × painted-face count) × coats ÷ 400 to 350 ft²/gal- A door painted front and back has a face count of two.
- Edges and detailed profiles are not reliably represented by flat face area; the optional allowance is user-controlled.
- Use the finish label spread rate if it differs from the typical planning range.
Cabinet piece schedule
| Piece | Measure | Face count |
|---|---|---|
| Door | width × height | 1 or 2 |
| Drawer front | width × height | usually 1 |
| Exposed box end | width × height | 1 |
| Face frame | sum rail and stile faces | painted faces only |
Work through the project
Number every removable piece
Pair the area worksheet with a hinge-side label so doors and hardware can return to the same opening.
Define the painted boundary
Decide whether backs, interiors, shelves, toe kicks, and exposed ends are included before measuring.
Make a sample panel
Follow the coating system instructions on one representative surface before committing the full kitchen.
Safety and scope
- Ventilate and follow product instructions for cleaners, primers, and coatings.
- Treat unknown older finishes as a testing question before abrasion.
