Measuring for a corner cabinet can be a tricky task that requires precision and a clear understanding of your space. Whether you’re renovating your kitchen, adding storage to a tricky nook, or simply upgrading your cabinetry, knowing how to accurately measure for a corner cabinet is essential to ensure a perfect fit. Getting this step right not only maximizes your storage potential but also enhances the overall functionality and aesthetic of your room.

Corner cabinets often come with unique shapes and dimensions that differ from standard cabinetry, making the measuring process a bit more complex. It’s not just about length and width; depth, angles, and clearances all play a crucial role in determining the right size and style of cabinet for your corner space. Understanding the basics of how to approach these measurements will save you time, money, and frustration down the line.

In this article, we’ll explore the fundamental concepts behind measuring for a corner cabinet, helping you gain confidence before you dive into the specifics. With the right preparation and know-how, you’ll be well on your way to creating a seamless, efficient corner storage solution that perfectly complements your home.

Measuring the Dimensions of the Corner Space

Accurately measuring the corner space is essential to ensure your corner cabinet fits perfectly and functions well. Start by measuring the two adjoining walls that form the corner. Use a tape measure to determine the length of each wall from the corner point to where the cabinet will end. This will give you the maximum potential width for your cabinet on each side.

Next, measure the depth from the corner along each wall to the front edge where the cabinet door will sit. This depth measurement is critical for both accessibility and aesthetics. Keep in mind that corner cabinets often have a diagonal front, so understanding the space available along the walls and into the room helps in selecting the correct cabinet style.

When measuring height, consider the distance from the floor to the bottom of any overhead obstructions, such as countertops, windowsills, or upper cabinets. This ensures that the cabinet height complements adjacent cabinetry and allows for proper installation.

Determining the Cabinet Opening Size

The cabinet opening size refers to the actual space the cabinet will occupy once installed, which may differ from the raw corner dimensions due to wall irregularities or trim. To measure the opening size:

  • Measure from the inside edge of one wall to the inside edge of the adjoining wall at the base.
  • Measure the height from the floor to the underside of any overhead structure.
  • Check for any obstructions or protrusions, such as electrical outlets or plumbing, that might affect installation.

These measurements help in selecting or customizing a cabinet that fits securely and leaves enough clearance for doors to open fully.

Measuring for Specialized Corner Cabinet Types

Different corner cabinet styles require unique measurements depending on their design:

  • Lazy Susan Cabinets: Measure the width and depth of the corner space, noting that these cabinets often occupy an L-shaped footprint with a rotating shelf inside. Ensure there is sufficient room for the door to swing and for the lazy Susan mechanism to rotate freely.
  • Diagonal Corner Cabinets: These cabinets have a front face set at a 45-degree angle. Measure the wall lengths, then measure the diagonal distance across the corner to verify that the cabinet will fit flush.
  • Blind Corner Cabinets: These extend deeper into the corner and typically have one side that is partially inaccessible without pull-out shelves. Accurate depth measurement is crucial, as well as noting the wall construction behind the cabinet.

Essential Tools for Accurate Measurement

Using the right tools ensures your measurements are precise and reliable. Essential tools include:

  • Tape measure (preferably 25 feet or longer)
  • Carpenter’s square for checking wall angles
  • Laser distance measurer for long or awkward spaces
  • Pencil and notepad or digital device for recording measurements
  • Level to check for even floor and wall surfaces

Measurement Checklist for Corner Cabinets

To avoid missing critical details, use the following checklist during measurement:

  • Measure length of both walls forming the corner
  • Measure depth from corner to front edge along each wall
  • Measure height from floor to underside of overhead structures
  • Check for obstructions (plumbing, electrical, trim)
  • Verify wall angles with carpenter’s square
  • Record measurements clearly and double-check accuracy

Preparing to Measure a Corner Cabinet

Before taking any measurements for a corner cabinet, it is essential to gather the right tools and understand the cabinet layout. Accurate measurements ensure the cabinet will fit perfectly and function as intended.

  • Tools Needed: Tape measure (preferably metal), pencil, notepad, level, and possibly a laser measure for more accuracy.
  • Clear the Area: Remove any items or obstructions inside and around the cabinet space to allow unobstructed access.
  • Identify Cabinet Type: Determine whether the corner cabinet is a diagonal, lazy Susan, blind corner, or angled cabinet, as this influences the measuring approach.
  • Check for Irregularities: Inspect walls and adjoining cabinets for uneven surfaces or out-of-square conditions which may require adjustment during installation.

Measuring the External Dimensions of the Corner Cabinet

Accurately measuring the external dimensions of a corner cabinet is crucial for ensuring it fits within the designated space in your kitchen or room.

Dimension How to Measure Notes
Width (along each wall) Measure from the inside edge of one adjoining wall to the inside edge of the other adjoining wall where the cabinet will sit. Record both walls separately as corner cabinets typically span two walls.
Depth Measure from the corner point (inside corner) straight out to the front edge where the cabinet face will be. Depth may vary depending on cabinet style; note maximum depth available.
Height Measure from the floor (or countertop if upper cabinet) to the top of the cabinet space. Include allowance for toe kicks or molding if applicable.

Measuring Internal Dimensions and Clearances

Understanding the internal dimensions and clearances ensures the cabinet provides adequate storage and operates without obstruction.

  • Internal Width: Measure from the inside wall of the cabinet box on one side to the inside wall on the other side.
  • Internal Depth: Measure from the back wall inside the cabinet straight to the front edge of the cabinet box.
  • Opening Width: Measure the width of the cabinet door or opening to ensure accessibility.
  • Clearance for Door Swing or Shelves: Account for clearance needed for hinged doors, lazy Susan rotation, or pull-out shelves.

Measuring for Specialized Corner Cabinet Features

Corner cabinets often include specialized features that require precise measurements to accommodate their functionality.

  • Lazy Susan: Measure the diameter of the circular shelf space, ensuring it clears the cabinet walls and door openings.
  • Blind Corner Pull-outs: Measure the depth and width of the pull-out mechanism space to confirm smooth operation.
  • Diagonal Cabinets: Measure the diagonal front face width and the depth from the corner to the front edge.
  • Corner Sink Cabinets: Measure the cabinet’s internal dimensions ensuring plumbing space is sufficient and that the sink will fit.

Tips to Ensure Accurate Corner Cabinet Measurements

  • Always double-check measurements by measuring twice to reduce errors.
  • Use a level to confirm walls and floors are even, as uneven surfaces can affect cabinet fit.
  • Take notes of any irregularities such as wall bumps, baseboard thickness, or molding that could impact the cabinet placement.
  • Consider adding small allowances for clearance, especially when dealing with doors and moving parts.
  • When measuring inside corners, use a framing square or combination square to verify angles are 90 degrees or note deviations.
