Wall Framing, Drywall, Paint & Wallpaper Calculators
Plan the wall from structure through finish. Choose the stage you are working on—framing, drywall, or the finished wall surface—and calculate the materials for that part of the project.
Calculate wall studs and framing materials
For a measured wall, use the dedicated Wall Framing Calculator to estimate stud count, plates and opening framing from your actual dimensions and on-center spacing.
Wall project reference guides
Use crawlable formulas and common-size tables for a fast answer, then use the calculators for your exact dimensions and openings.
Wall Framing Calculator Guide
Stud-count formulas, 16- and 24-inch spacing examples, openings and framing takeoff guidance.

Framing establishes the wall geometry and openings. Drywall covers that structure, while paint or wallpaper finishes the surface. PlanDIYBuild keeps these as separate takeoffs so structural assumptions, sheet quantities and finish coverage remain clear. Verify structural member sizing, header requirements, fastening schedules and local code requirements before construction.
