3 Tips for Determining How Long of a Bracket You Need (1)

Using shelf brackets is a great way to set up décor and organizational pieces at home. However, knowing how long of a bracket you need can be a challenge. You don’t want a bracket that’s too short and unstable, and you also don’t want one that’s too long and unsightly. Determining the correct size bracket for your project can be overwhelming, but we can help. We’ll share three tips for determining how long of a bracket you need.

Measure the Ledge or Shelf

The first step in determining how long of a bracket you need is to measure the ledge or shelf you’re setting up. The size of the shelf will determine the length of the bracket necessary to support it. The bracket should be at least 2/3 the length of the shelf to support it. For example, if your shelf is 36 inches long, then a 24-inch bracket will be sufficient.

Consider the Weight Limit

The weight of the objects you’ll put on the shelf will also determine the bracket size you need. You can choose a smaller bracket if you’re using the shelf to hold lightweight items like dolls or books. However, if you plan on storing heavier objects, like kitchen appliances or woodworking tools, a larger bracket is necessary. Always check the weight capacity of the bracket before purchasing.

Consider the Aesthetics

It’s also important to consider the aesthetic of the bracket. The bracket’s style and size can impact the room’s look. A bracket that’s too long can make the shelving look awkward and unattractive, so consider the style of the bracket in conjunction with the style of the room when making your selection.

Selecting the right size bracket for your shelf may seem daunting, but it doesn’t have to be. Check out Right On Bracket’s selection of modern shelf brackets today, and find a bracket that meets your needs.
