# What angle do I cut shelf brackets?

## What angle do I cut shelf brackets?

The diagonal support for the wood shelf brackets is cut at 45 degrees on each end.

How do you calculate the angle of a shelf support?

Find the two missing angles of the shelf support (angles “A” and “B”) using the inverse trigonometric functions for sine, cosine and tangents. For example, to find angle “A,” use the measurements for sides “b” and “c,” which are adjacent to angle “A.” Cos A = b/c. So in the example, cos A = 8/14.42, or 0.55.

### What angle supports the most weight?

45 degrees is the strongest brace angle for a right-angle triangle, but the absolutely strongest is an equilateral triangle with three 60 degree angles.

How big should a bracket be for a shelf?

Shelf brackets range in size from 5 inches deep (for shelves holding paperback books) to 24 inches (for desktops and other large spaces). Plan to use brackets that are just a bit shorter than the depth of the shelves. For example, if you want shelves that are 8 inches deep, use 7-inch brackets.

How do you make a wood shelf?

Here’s a simple set of wood shelf brackets you can start with. Cut the 2- by 6-inch boards with a chop saw, table saw or hand-held crosscut saw into two pieces so that each has a square end. Sketch the bracket design on a piece of paper, cut it out with scissors, then trace the design on your 2- by 6-inch board with a pencil.

### What are shelf brackets?

Shelf brackets, also sometimes called corbels, are basically just dressed up right triangles – having one 90-degree angle – and are generally made of wood.
