Wood Joints for Beginners: 7 Joints Explained Simply

A joint is how two pieces of wood connect. Picking the right one makes a project stronger, better looking and easier to build.

1. Butt joint

One board meets another end-to-face, held with screws or nails. Fast and simple, but weak with glue alone because end grain glues poorly. Fine for boxes, shelves and rough projects.

2. Pocket hole joint

A jig drills an angled hole so a screw pulls two boards together. Very fast and strong enough for face frames, cabinets and most furniture for beginners. The holes go on the hidden side.

3. Dado

A groove cut across a board so another board sits inside it. Classic for bookcase shelves; the groove carries the load.

4. Rabbet

An L-shaped notch along an edge. Used for box corners and to set in cabinet backs.

5. Lap joint

Half the thickness is removed from each board where they overlap, so they sit flush. Strong and simple for frames and tables.

6. Dowel joint

Wooden pins glued into matching holes. A dowel jig keeps holes aligned. Good for edge joints and simple frames.

7. Mortise and tenon

A tongue (tenon) fits into a slot (mortise). One of the strongest traditional joints, used for tables, chairs and doors. More skill required, but worth learning.

Which joint for which project?

Project	Good joint
Shop shelving	Butt + screws, or dado
Bookcase	Dado + rabbet back
Face frame	Pocket hole
Picture frame	Miter (with splines)
Table legs and aprons	Mortise and tenon or pocket hole

Gluing tips

Glue bonds best long grain to long grain. Apply a thin, even coat, clamp until you see a small bead squeeze out and clean up the excess before it dries.
