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?

CalculatorWhat it needsWhat it gives you
StudWall length, stud spacing (16" or 24" o.c.), plate countStud count including corners, T-walls, and openings
PlywoodWall or floor area to sheathe, panel sizeSheet count with waste allowance
StairTotal rise (floor to floor) and desired tread depthRiser count, actual riser height, tread count, and total run
BaseboardRoom perimeter, door and opening widthsLinear feet of baseboard and piece count for a given board length

Suggested project order

  1. Stud — frame the wall first; every other framing step depends on it.
  2. Plywood — sheathe the framed wall or floor.
  3. Stair — lay out risers and treads for any floor openings.
  4. Baseboard — finish trim once walls and floors are closed in.
