Framing Calculator
Estimate studs, plates, and headers for wall framing.
How It Works
Studs = (ceil((Length × 12) ÷ Spacing) + 1) × Walls. Plate linear ft = 2 × Length × Walls. Plate pieces = ceil(Plate linear ft ÷ 8).
Example
For a 24 ft wall, 16 in spacing, 2 walls: 19 studs each = 38 total, 96 ft of plate → 12 × 8 ft plates.
Frequently Asked Questions
What are plates?
Top and bottom horizontal 2x4s that cap each wall. Each wall needs two runs, hence the factor of 2.
Why 8 ft plate pieces?
Lumber is typically sold in 8 ft lengths, so total plate footage is rounded up to full pieces.
Does this include openings?
No — door and window headers, kings, and trimmers are extra framing beyond the stud count.
