Framing Calculator

Estimate studs and total cost for a stud wall.

Section 1 — Dimensions

Common spacings: 400 mm (≈16″), 486 mm (≈19.2″), 600 mm (≈24″).

Section 2 — Pricing
%

Waste accounts for offcuts, defects, and mistakes. Many builders use ~10–15%.

Results
Studs needed
Rounded to a whole stud (no waste).
Total cost
Includes selected waste %.
Step-by-step derivation
  1. Convert inputs to meters.
  2. Compute base studs: N = ⌊L / s⌋ + 1 (stud at both ends).
  3. Apply waste to cost: Cost = N × (1 + w) × price, where w is waste in decimal.
References
  • Stud count along a wall with on-center spacing uses N = ⌊L / s⌋ + 1 so both ends are studded.
  • Typical on-center spacings: 16″, 19.2″, 24″ (≈ 400 mm, ~486 mm, 600 mm).
  • Total cost commonly includes a waste margin to cover offcuts and defects.
