Framing Calculators
Estimate studs, plywood, stair parts, and baseboard trim for framing and finish carpentry.
Calculators
Which measurement should I take first?
Start with wall length and stud spacing (16" or 24" on center) for framing counts — most other framing calculators build on the same wall dimensions. If you're sheathing the wall, measure the same span for plywood panel counts. Stair and baseboard calculators instead key off total rise/run and room perimeter, so take those measurements separately once the surrounding walls are framed.
Which calculator do I need?
| Calculator | What it needs | What it gives you |
|---|---|---|
| Stud | Wall length, stud spacing (16" or 24" o.c.), plate count | Stud count including corners, T-walls, and openings |
| Plywood | Wall or floor area to sheathe, panel size | Sheet count with waste allowance |
| Stair | Total rise (floor to floor) and desired tread depth | Riser count, actual riser height, tread count, and total run |
| Baseboard | Room perimeter, door and opening widths | Linear feet of baseboard and piece count for a given board length |
