Framing Calculators is an independent educational website. We build free, fast calculators and plain-language reference pages about carpentry and framing math: stairs and stringers, board feet and lumber, roof pitch and rafters, wall studs, decks, drywall and tile.
What we do
- Calculators you can check. Every tool shows its formula and works in feet-inches or metric, so you can verify any result with a tape and a pencil.
- Code numbers with section references. Stair, guard, roof-slope, framing and deck limits are quoted from the model codes (IRC, Approved Document K, the National Building Code of Canada, the NCC) with their section numbers. Lumber sizes and design values come from the American Softwood Lumber Standard and the American Wood Council.
- No selling. We do not sell products, we do not link to sellers, and we do not accept payment for reviews or placements.
Who we are
Framing Calculators is run by a small independent editorial team based in Türkiye. We are not affiliated with any lumber yard, home centre, manufacturer, code body or contractor.
