Measuring a corner base cabinet might seem like a daunting task, but with the right tools and steps, you can ensure a perfect fit in your kitchen or bathroom. This guide will walk you through the process, from gathering your materials to calculating the dimensions, ensuring a precise measurement every time.
Gather Your Materials
Before you begin, make sure you have the following tools and materials:
- Tape measure
- Pencil
- Paper or a notepad
- Calculator (optional)
Understand Corner Cabinet Types
Corner base cabinets come in two main types: diagonal and blind. Understanding the difference between the two will help you measure correctly:

- Diagonal cabinets: These cabinets are designed to fit into a 90-degree corner, with the doors opening diagonally. They are typically 36 inches wide.
- Blind cabinets: These cabinets are designed to fit into a 90-degree corner, with one door opening normally and the other door opening at a 90-degree angle. They are typically 24 inches wide.
Measure the Available Space
Before you measure for your cabinet, ensure the space you have is suitable. Measure the width and depth of the area where the cabinet will go, and make sure it matches the dimensions of the cabinet you want to install.
Width
Measure the width of the space where the cabinet will go. This should match the width of the cabinet you want to install. For diagonal cabinets, this is typically 36 inches, and for blind cabinets, it's typically 24 inches.
Depth
Measure the depth of the space where the cabinet will go. Standard base cabinets are 24 inches deep, but some spaces might require a shallower or deeper cabinet. Make sure the depth of the cabinet you choose matches the depth of the space.

Height
Measure the height of the space where the cabinet will go. Standard base cabinets are 34.5 inches tall, but some spaces might require a taller or shorter cabinet. Make sure the height of the cabinet you choose matches the height of the space.
Measure the Cabinet Opening
Once you've confirmed the space matches the cabinet's dimensions, it's time to measure the opening where the cabinet will go. This is especially important if you're replacing an existing cabinet.
Width
Measure the width of the opening. This should match the width of the cabinet you want to install. If the opening is too wide, you might need to install a filler strip to make it the correct width.

Depth
Measure the depth of the opening. This should match the depth of the cabinet you want to install. If the opening is too deep, you might need to install a filler strip to make it the correct depth.
Calculate the Cabinet Dimensions
Once you've measured the space and the opening, you can calculate the dimensions of the cabinet you need. If the measurements match the dimensions of a standard cabinet, you can use that. If not, you might need to order a custom cabinet.
Consider Other Factors
Before you order your cabinet, consider other factors that might affect the measurement:
- Plumbing: If you're installing the cabinet near plumbing, make sure the cabinet's height and depth will accommodate the pipes.
- Countertops: If you're installing countertops, make sure the cabinet's height and depth will accommodate the countertop material you've chosen.
- Doors and Drawers: Make sure the cabinet's doors and drawers will open fully in the space you have.
Measuring a corner base cabinet might seem complex, but with these steps, you can ensure a perfect fit every time. Happy measuring!
