Wood Glue Coverage Calculator

Estimate how much wood glue you need for a joint, by joint length and type.

Glue Needed
ml
Approximate volume.

Usage Tip

Apply a thin even film to both surfaces and clamp until you see a light squeeze-out bead; too much glue just makes cleanup harder.

THE MATH
volume (ml) = linear feet × 12 × 0.5 × joint multiplier
Wood glue is applied along a joint at roughly half a milliliter per inch of joint. Joints that glue both faces use more; a single face uses less.
Enter the total linear feet of joint and the joint type.
Edge-to-edge glue-ups coat both faces, single-face joints use less, and mortise-and-tenon joints use more for the extra surface.
