Wall Framing Calculator

Estimate studs, top plates, bottom plates, and headers for any wall layout. Supports 16" and 24" on-center spacing per IRC requirements.

Wall framing estimates depend on wall length, stud spacing, and wall height. At 16" on-center, you need roughly one stud per linear foot of wall plus one. At 24" OC, the count drops but requires 2×6 lumber in many load-bearing applications. This calculator also estimates top plate (double) and bottom plate quantities, plus basic header material for standard openings.

Frequently Asked Questions

When can I use 24-inch on-center spacing?

IRC Section R602.3 allows 24" OC for load-bearing walls with 2×6 studs and certain single-story conditions. Always verify with your local building department and structural engineer.

How many extra studs should I order?

A 10–15% overage is standard for wall framing. Warped or damaged studs are common — having extras on site prevents delays.

Does this include corner and intersection assemblies?

The calculator estimates standard studs and plates. Add 2–3 extra studs per corner and wall intersection for backing and bracing per standard practice.

Estimates are for planning purposes only. Verify quantities with your supplier and confirm code requirements with your local building department.
