Tenon: Woodworking Calculator
Carpentry Cut List, Board Foot
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Free woodworking calculators that get the math right — board feet, cut lists, fractions, miters. Now price your builds for profit & track your shop stock with Pro.
Tenon is the woodworking calculator that gets the math right — so you cut once, buy the right amount, and charge what your work is worth.
EIGHT WOODWORKING CALCULATORS — ALWAYS FREE
• Cut List — pack your cuts onto the fewest boards, saw kerf included
• Sheet Optimizer — a real 2D cut map for every sheet of plywood
• Board Foot — lumber volume & cost, nominal or actual
• Fraction — feet-and-inches tape math with real fractions
• Miter — angles for any corner
• Stair — risers, treads & stringer with an instant code check
• Framing — stud & plate layout
• Board Spacing — even gaps, every time
IMPERIAL OR METRIC — NEVER MIXED
Every result reads the way wood is actually bought and cut. Switch between feet-and-inches (fractions or decimal) and millimetres anytime — Tenon never mixes units on one screen.
