Types of Framing Joints

Updated April 17, 2017

A framing joint is essentially the method of joining two pieces of timber together. In the building industry, framing is the term given to the woodwork that's required to build a house. There are various methods of joining wood because different angles require different measures to make the joint as strong as possible.

Half Lap Joint

A half lap joint is very common in building construction. It's usually used for joining two pieces of wood at a right angle by taking away an equal amount of wood from each piece. When the two pieces meet, they should do so seamlessly.

Mitred Half Lap

The mitred half lap is similar to the half lap; however, the perpendicular joint is mitred at a 45-degree angle. This joint is commonly used in doors and cabinets because it uses the strength of the half lap joint but has elegance.

Cross Lap Joint

This joint is exactly the same as the half lap joint, except this is used for joining one or both pieces in middle of the wood rather than at the end. This is a simple framing or bracing joint that's common in wooden support frames of any size.

Dovetail Lap Joint

The dovetail joint is one of the most complicated joints to manufacture because the pieces of wood have been cut at angles. Both the accepting hole and the joining wood are shaped like a dove's tail to resist any excess force pulling on the joint.
