Factors That Affect Corner Cabinet Dimensions

Several factors come into play when determining the ideal size for a corner cabinet in your space.

  • Wall vs. Base: Wall corner cabinets are mounted above countertops, while base units sit directly on the floor. Wall cabinets are generally smaller.
  • Available Space: Take measurements of the full diagonal corner space to ensure the cabinet will fit. Also measure any existing cabinets or appliances adjoining the corner cabinet.
  • Design Elements: Angled cabinet doors can provide fuller access to the cabinet interior than straight doors. Diagonal cabinet doors are a way to achieve this.
  • Access Needs: Consider pull-outs, blind corner organizers, and lazy susans to maximize usable space in the corner. Allow for clearance.
  • Appliances: If housing a refrigerator or other appliance, measure it to coordinate cabinet sizes.
  • Usage: Larger dimensions for a pantry or appliance garage; smaller for a cleaning supply cabinet.

Consider these factors when figuring out the best corner cabinet size for your unique space and needs.

Planning Your Corner Cabinet Design

Careful planning and measurement are crucial. They are key to successfully incorporating corner cabinets into your space. Here are some tips:

  • Use a tape measure to measure the full diagonal corner. Measure from the inner edges of the adjoining walls. This will help you find the maximum available space.
  • Consider traffic zones in the room layout. Don’t size corner cabinets too large if they will impede movement.
  • Maximize storage capacity by selecting the largest size the corner space will allow. For example, a 36×36 inch cabinet rather than 24×24.
  • Ensure cabinets are accessible. Lazy susans, pull-outs, and other interior organizers can help.
  • For especially angled corners, you may need to use an angled filler panel to square-off the space. Custom cabinets can also be angled specifically.
  • To select a manufactured corner cabinet, have the corner measurements on hand. Or for a custom cabinet, provide your designer or carpenter with the full dimensions.
  • Use your planner’s 3D design visuals or room templates. Test out various corner cabinet sizes. Do this before finalizing decisions.

Mapping out corner spaces maximizes awkward corner storage. It pays dividends in maximizing capacity.

Customized Corner Cabinets

For unique storage needs, customized corner cabinets can be the perfect solution. Here’s an overview:

  • Benefits: Custom cabinets are built to your exact specifications. You can get a tailored fit for your space and storage requirements.
  • Ordering: Work with a cabinet maker or carpenter to design the customized corner cabinet. Provide them with your measurements and usage needs. Expect a 4-6 week timeline for production. Costs vary widely based on materials and complexity.
  • Design Options: Consider details like cabinet depth, divider panels, roll-outs, vertical storage additions, and custom drawer configurations. Decide if you want an angled or straight cabinet shape.
  • Modifying Existing Cabinets: You may be able to modify existing corner cabinets. Add new depths, heights, shelves, etc. to better suit your space. This can be more practical than installing completely new customized cabinets.
  • Materials: Custom cabinets can be constructed from wood, MDF, metal, high-pressure laminates, and more. Discuss options with your carpenter.

The customized approach takes more time and costs more. However, the end result is a high-functioning, tailored corner storage solution.
