Pocket Screw Calculator - Sizing and Placement for Pocket-Hole Joinery
Pocket screws are one of the fastest ways to join cabinet face frames and boxes, using an angled pilot hole to drive a self-tapping screw invisibly into the mating piece. This calculator recommends screw length, angle, and spacing based on your material thickness and joint type.
How to Use the Pocket Screw Calculator
- Material Thickness: Choose from 1/2" up to 1.5"
- Screw Type: Coarse thread, fine thread, or self-tapping
- Joint Orientation: Face frame, edge-to-edge, or end-to-face
- Pocket Hole Angle: 15 degrees (standard) or 7 degrees (low-profile, for tight spaces)
Screw Selection Reference
The 15-degree angle is the standard jig setting and works for almost all cabinet and furniture joinery; the 7-degree low-angle option is used when the pocket hole would otherwise be too close to an edge or visible surface. Coarse-thread screws grip better in softwood and plywood, while fine-thread screws are the better choice in dense hardwoods where coarse threads can split the material. As a rule of thumb, use a screw roughly 1 inch longer than your material is thick - 3/4" stock typically pairs with a 1-1/4" coarse-thread pocket screw. Space screws every 6-8 inches along a face-frame joint for solid holding power without overdoing it.
