Trim is not part of the wall — it is a separate, slower line of work, and painters price it by the linear foot. Measure the run of baseboard, crown, or casing, multiply by a per-foot rate, and keep it off the wall-area bid.
Sixty feet of baseboard at $2.50 a foot is $150 for that room's trim.
The example
Three rooms, each with a run of trim in linear feet and a per-foot rate for that trim type.
| A | B | C | D | |
|---|---|---|---|---|
| 1 | Room | Lin ft | Rate/ft | Trim $ |
| 2 | Living | 60 | 2.50 | 150 |
| 3 | Kitchen | 42 | 2.50 | 105 |
| 4 | Hall crown | 30 | 3.50 | 105 |
The formula
Linear feet, straight into a per-foot rate:
How it works
Just two inputs:
B2is the run of trim in linear feet — measure the perimeter for baseboard, the top of the wall for crown, around openings for casing.C2is your per-foot rate for that trim type; crown and detailed casing carry a higher rate than plain baseboard.- Keep each trim type on its own row with its own rate, since they paint at different speeds.
- Sum the rows for the room's total trim charge, and keep it as a line separate from the walls.
Add a coats factor if the trim needs two coats plus a primer — multiply the rate or the linear feet accordingly.

Enter the run of trim in linear feet and your per-foot rate.
Variations
Two coats
Roughly double the per-foot rate for a second finish coat.
Whole-house trim total
Sum every room's trim charge for the job line.
Pitfalls & errors
Do not subtract trim from the wall area and do not roll it into the per-square-foot wall price. Trim is slower per unit and belongs on its own linear-foot line.
Crown and multi-piece casing take longer than flat baseboard. Use a separate, higher rate for those rather than one blended trim rate.
