Pocket Hole Spacing Calculator

Calculate pocket hole spacing for a board: end holes plus evenly spaced middle holes.

Pocket Holes
— holes
End holes plus middles.

Usage Tip

Keep holes back from the very end so the screw does not blow out; clamp the joint before driving to stop it from shifting.

THE MATH
end holes sit 2 in from each end
middle holes fill the span at the target spacing
Pocket holes join boards edge to edge or to a frame. A hole sits about 2 inches in from each end, with evenly spaced holes filling the middle.
Enter the board length and a target spacing (6 to 8 inches for face frames, 8 to 12 for cabinet boxes).
The result is the total hole count and the actual even spacing.
