# What size shelf bracket do I need?

**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**.

Keeping this in view, what size brackets for 300mm shelf?

Wooden **brackets** Choose from **brackets** that can be used on **shelves** from 150mm to **300mm**, or ones that can be used on **shelves** from 250mm to 450mm. **Brackets** are reversible, so they can be used in 2 different positions and have a maximum load of 40kg.

Subsequently, question is, how much can a shelf overhang a bracket? If your studs are spaced 24 inches apart, plan to attach a standard to each stud. **Shelves** should **overhang** the side **brackets** by no more than 6 inches.

Also Know, how wide can shelves be without support?

**Bookshelf** width is typically no more than 12 inches. If the space is limited, the **shelf can** be reduced to 9 inches. Single **bookcase** units with two sides, top and bottom should be no wider than 36 inches **without** a center **support**.

Can shelf brackets be used upside down?

The top-most screw holding the **bracket** in would be supporting the most weight. If the **bracket** was **upside down**, all the weight would be going straight **down**. The corner of the **bracket** would be a fulcrum point and the angled piece would then be pulling all the weight out from the wall.
