Measuring for a Perfectly Fitted Corner Shelf
Installing a corner shelf can enhance your space's functionality and aesthetics, but accurate measurement is crucial for a seamless fit. This guide will walk you through the process, ensuring your corner shelf is both secure and visually appealing.
Understanding Your Corner
Before you start measuring, understand the type of corner you're dealing with. Corners can be inside (where two walls meet) or outside (where a wall meets the ceiling). This guide focuses on inside corners, as they are the most common for installing shelves.
Gather Your Tools
- Tape measure
- Pencil
- Level
- Corner shelf bracket kit
- Drill (if not using a hammer and nails)
Measure the Corner's Depth
The depth of your corner will determine the size of the shelf you need. Use your tape measure to find the distance from the outer edge of one wall to the outer edge of the other wall. This is your corner's depth.

Consider the Shelf's Depth
When choosing a shelf, consider its depth. A deeper shelf will hold more items but may protrude into the room more. A shallower shelf will be less obtrusive but hold fewer items.
Measure the Height
Decide on the height at which you want your shelf to sit. Use your tape measure to mark this height on both walls. Ensure the marks are level using your level tool. The distance between these marks is the height your shelf will span.
Account for the Shelf's Thickness
When measuring the height, don't forget to account for the thickness of the shelf itself. Most shelves are around 1" thick, but this can vary.

Measure the Width
The width of your shelf will be determined by the length of the wall you want it to span. Use your tape measure to find the distance from the corner to the point where you want the shelf to end. This is your shelf's width.
Consider Support Brackets
Most corner shelves require support brackets. These will add to the width of your shelf. Make sure to account for their width in your measurements.
Installing the Shelf
Once you've measured and purchased your shelf, it's time to install it. Start by marking the location of the shelf brackets on the walls. Use your level to ensure these marks are level.
Attach the brackets to the walls using the hardware provided. If your kit doesn't include screws, use nails. Ensure the brackets are securely attached to the studs in the wall for maximum support.
Place your shelf onto the brackets, ensuring it's level and flush with the wall. Secure it in place using the provided hardware or screws.
Finishing Touches
Once your shelf is installed, you can paint it to match your walls or leave it as is. Now you're ready to fill your new shelf with books, decor, or whatever you like!
