Box and Case Making Calculations

Box and case making is one of the most rewarding areas of woodworking, combining precise joinery with decorative techniques. Getting the dimensions right is critical — a box that is too tight won't close properly, and one that is too loose looks sloppy.

When designing a box, you need to work backwards from the desired internal dimensions to calculate the material sizes. Our box dimension calculator converts your target internal size into cutting dimensions for sides, base, and lid, accounting for material thickness and joint type.

Mitred corners give boxes a clean, elegant look but require precise cuts and careful sizing. Our mitre box calculator works out the exact material lengths needed so your mitres close perfectly.

Veneering adds beautiful figured wood to box surfaces without the cost of solid timber. Our veneer calculator estimates the number of veneer sheets needed, including allowance for trimming and matching.
