How to Use This Calculator
- Enter Number of doors, Door height (ft), and Door width (ft).
- Set Casing width (in), Reveal (in), and Sides per door.
- Adjust Cost per linear ft ($), Waste factor (%) as needed.
- Review the Total linear feet result.
- Use Linear ft per door and Linear ft (with waste) to inform your decision.
How the result changes with Number of doors
| Number of doors | Total linear feet |
|---|---|
| 11 | 361.85 |
| 36 | 1,184.22 |
| 65 | 2,138.17 |
| 90 | 2,960.55 |
What each input means
- Number of doors
- Total doors needing casing.
- Door height (ft)
- Height of the door opening (standard is 6 ft 8 in = 6.67 ft).
- Door width (ft)
- Width of the door opening (standard is 2 ft 8 in = 2.67 ft).
- Casing width (in)
- Width of the casing profile in inches.
- Reveal (in)
- Setback from jamb edge to casing edge (typically 3/16 in).
- Sides per door
- 1 for one-sided (closet) or 2 for both sides.
- Cost per linear ft ($)
- Price per linear foot of casing material.
- Waste factor (%)
- Extra material for cuts and waste.
What each result means
- Linear ft per door
- Casing material needed per door (both sides if applicable).
- Total linear feet
- Total casing material for all doors.
- Linear ft (with waste)
- Total footage including waste factor.
- Total miter cuts
- Number of 45-degree miter cuts at header corners.

How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersNumber of doors = 5, Door height (ft) = 6.67, Door width (ft) = 2.67, Casing width (in) = 2.25 = 8 input(s) provided
- Calculate Total linear feetTotal linear feet = lfPerDoor * doorCount164.47 = 164.47
- Calculate Linear ft per doorLinear ft per door = lfPerSide * sidesPerDoor32.89 = 32.89
- Calculate Linear ftLinear ft = totalLinearFt * (1 + wastePct / 100)180.92 = 180.92
