Measuring a corner wall cabinet accurately is crucial for ensuring a perfect fit and a polished look in your space. Whether you're installing a new cabinet or replacing an existing one, this guide will walk you through the process step-by-step, providing clear instructions and helpful tips to make your project a success.
Understanding Corner Wall Cabinets
Corner wall cabinets, also known as L-shaped cabinets, are designed to fit snugly into the corner of a room. They are typically used in kitchens and bathrooms to maximize storage space in often underutilized corners. Before you start measuring, it's essential to understand the different types of corner cabinets to ensure you're measuring correctly.
- Diagonal Cabinets: These are the most common types, featuring a diagonal back that fits into the corner.
- Blind Corner Cabinets: These cabinets have a blind back, meaning they don't extend into the corner. They are often used with a pull-out mechanism to access the back of the cabinet.
Gather Your Tools
Before you start measuring, gather the necessary tools to ensure the process goes smoothly. You'll need:

- A measuring tape
- A level
- A pencil
- Paper and a calculator
Measure the Cabinet Opening
The first step in measuring for a corner wall cabinet is to determine the size of the cabinet opening. This will help you choose the right cabinet size and ensure a proper fit.
- Using your measuring tape, measure the width of the wall space where the cabinet will be installed. This is the total width of the cabinet you'll need.
- Next, measure the depth of the wall space. This is the depth of the cabinet you'll need.
- Finally, measure the height of the wall space. This is the height of the cabinet you'll need.
Record these measurements and use them to determine the cabinet size you need. Keep in mind that cabinet sizes are typically measured in width by height by depth.
Measure the Cabinet Itself
Once you've determined the size of the cabinet you need, it's time to measure the cabinet itself to ensure it fits into the space. This is especially important if you're replacing an existing cabinet.

- Measure the width of the cabinet. This should match the width of the wall space you measured earlier.
- Measure the depth of the cabinet. This should match the depth of the wall space. However, keep in mind that the depth of the cabinet may be slightly less than the depth of the wall space to account for the cabinet's thickness.
- Measure the height of the cabinet. This should match the height of the wall space.
If the measurements don't match, you may need to adjust the size of the cabinet or the size of the wall opening.
Consider Other Factors
Before you finalize your measurements, consider other factors that could impact the fit of your corner wall cabinet.
- Plumbing and Electrical Fixtures: If your cabinet is going in a kitchen or bathroom, you'll need to consider the location of plumbing and electrical fixtures. Make sure the cabinet won't interfere with these fixtures.
- Doors and Windows: Ensure the cabinet won't block any doors or windows.
- Base Cabinets: If you're installing the corner wall cabinet above base cabinets, make sure the height of the wall cabinet is compatible with the height of the base cabinets.
Conclusion
Measuring for a corner wall cabinet may seem daunting, but with careful planning and accurate measurements, you can ensure a perfect fit. By following the steps outlined in this guide, you'll be well on your way to installing a corner wall cabinet that maximizes your space and enhances the look of your room.
