Mortise and Tenon Calculator
Calculate the perfect dimensions for mortise and tenon joints. Determine woodworking joint specifications based on material thickness, joint type, and wood species.
Step 1: Material & Joint Type
Understanding Joint Proportions
Traditional mortise and tenon joints typically use a 1:3 ratio: tenon thickness = 1/3 of material thickness. This provides optimal strength while maintaining structural integrity.
Step 2: Wood & Measurement
About Wood Selection
Hardwoods typically allow for thinner tenons due to their strength. Softwoods may require slightly thicker tenons. Always consider wood movement and grain direction when designing joints.

Mortise & Tenon Formula
Tenon Thickness = Material Thickness × Tenon Ratio
To calculate tenon dimensions: Multiply your material thickness by the tenon ratio. Mortise width should be 0.5-1mm larger than tenon thickness for proper fit.
