Measuring kitchen cabinets correctly is crucial for a successful renovation or replacement project. This guide will walk you through the process of accurately measuring your existing cabinets to ensure new ones fit perfectly.
Why Precise Cabinet Measurements Matter
Fathoming the importance of accurate kitchen cabinet measurements is the first step in any cabinet project. Incorrect measurements can lead to costly mistakes, delays, and frustration. Whether you are ordering custom kitchen cabinet measurements or selecting from standard kitchen cabinet sizes, precision is key. Getting your kitchen cabinet dimensions right from the start prevents issues like cabinets that don’t fit, doors that won’t open, or appliances that can’t be installed. This cabinet measurement guide is designed to equip you with the knowledge to avoid these pitfalls.
Gathering Your Measuring Tools
Before you begin, ensure you have the right tools for the job. A good quality tape measure is essential. Consider a metal tape measure that locks in place for easier one-person use. A pencil and paper, or a digital device for notes, will also be necessary. A step stool might be needed to reach higher areas.
Essential Measuring Equipment:
- Tape Measure: A sturdy, 16-foot or longer metal tape measure is ideal.
- Pencil and Paper: For jotting down all your measurements.
- Notebook or Digital Device: To keep your notes organized.
- Step Stool (Optional): For safely reaching taller cabinets.
- Helper (Optional but Recommended): An extra pair of hands can make measuring easier and more accurate.
Measuring Your Existing Kitchen Cabinets: A Step-by-Step Approach
The process of measuring kitchen cabinet size involves taking accurate readings of the height, width, and depth of each cabinet. This section breaks down how to measure each aspect.
Cabinet Width Measurement:
When measuring width, always measure from the widest point of the cabinet.
- Base Cabinets: Measure the length of the cabinet from the left edge to the right edge. If there’s a toe kick, measure from the outer surface of the cabinet box, not the front of the toe kick.
- Wall Cabinets: Similar to base cabinets, measure the full length from one side to the other.
Tip: Measure the cabinet frame itself, not just the doors. This gives you the true size of the cabinet box.
Cabinet Height Measurement:
Height measurements are straightforward but require attention to detail.
- Base Cabinets: Measure from the floor to the top of the cabinet box. If there’s a countertop, measure up to the underside of the countertop.
- Wall Cabinets: Measure from the bottom edge of the cabinet to the top edge.
Important Consideration: For base cabinets, remember that standard countertop height is usually around 36 inches. Your cabinet height will be less than this, typically around 34.5 inches, to accommodate the countertop thickness.
How to Measure Cabinet Depth:
Depth measurement is critical, especially for wall cabinets, to ensure they don’t protrude too much or get in the way.
- Base Cabinets: Measure from the front of the cabinet box (where the doors attach) to the back. This measurement is usually taken without the countertop.
- Wall Cabinets: Measure from the front of the cabinet box to the back. Be aware of any obstructions behind the cabinet, like pipes or windowsills.
Standard Depth: Most standard base cabinets have a depth of 24 inches, and wall cabinets have a depth of 12-15 inches.
Measuring Specific Cabinet Components
Beyond the overall kitchen cabinet dimensions, you’ll need to measure individual components, particularly doors and drawers. This is especially important if you’re replacing doors or trying to match existing styles.
Measuring Cabinet Doors:
Accurate measuring cabinet doors is essential for a proper fit and appearance.
- Overlay vs. Inset: First, determine if your doors are overlay (they sit on top of the cabinet frame) or inset (they fit inside the frame). Most modern cabinets use overlay doors.
- Overlay Doors:
- Measure the height and width of the door itself.
- Measure the width of the cabinet opening and add the desired overlap (e.g., 1/2 inch on each side).
- Inset Doors:
- Measure the cabinet opening precisely. The door will be sized to fit snugly within this opening.
For Overlay Doors, you generally measure the door’s actual dimensions. For example, if a door covers a 12-inch wide opening and you want a 1/2-inch overlap on each side, the door itself might be 13 inches wide. However, when ordering, you typically provide the opening size and the desired overlay.
Measuring Drawer Fronts:
Similar to cabinet doors, drawer front measurements depend on the overlay style.
- Overlay Drawer Fronts: Measure the height and width of the drawer front.
- Inset Drawer Fronts: Measure the opening where the drawer front will sit.
Measuring for Wall and Base Cabinets: Detailed Breakdown
Let’s delve into the specifics of measuring different types of cabinets.
Wall Cabinets:
Wall cabinets are mounted above the counter.
Width Measurement for Wall Cabinets:
- Measure the horizontal length of the cabinet box from one side to the other.
- Important: If you are measuring an existing wall cabinet that is already installed, measure the cabinet box itself. Do not include any filler strips or decorative molding in your primary width measurement.
Height Measurement for Wall Cabinets:
- Measure the vertical dimension from the bottom edge of the cabinet box to the top edge.
- Consider Ceiling Height: When planning for new wall cabinets, always consider your ceiling height. Standard wall cabinet heights are 30, 36, or 42 inches, but custom options are available. The space between the countertop and the bottom of the wall cabinet is also crucial, typically 18 inches.
Depth Measurement for Wall Cabinets:
- Measure from the front face of the cabinet box to the back.
- Check for Obstructions: Ensure there are no pipes, electrical outlets, or other fixtures that might interfere with the depth of your chosen cabinets.
Base Cabinets:
Base cabinets sit on the floor and support countertops.
Width Measurement for Base Cabinets:
- Measure the horizontal length of the cabinet box from left to right.
- Account for Toe Kick: The measurement should be taken from the outermost vertical surface of the cabinet box, excluding the toe kick projection.
Height Measurement for Base Cabinets:
- Measure from the floor to the top of the cabinet box.
- Standard Countertop Clearance: Remember that standard base cabinets (typically 34.5 inches high) are designed to be used with a countertop that brings the total height to around 36 inches.
Depth Measurement for Base Cabinets:
- Measure from the front of the cabinet box to the back.
- Standard Depth: Most base cabinets are 24 inches deep to accommodate standard countertop overhangs.
Measuring for Special Cabinet Types
Some kitchen layouts include specialized cabinets that require slightly different measurement approaches.
Corner Cabinets:
Corner cabinets are often L-shaped or have a diagonal front.
- L-Shaped Corner Cabinets: Measure the width of the cabinet along each wall it occupies. For example, if the cabinet extends 36 inches down one wall and 36 inches down the adjacent wall, your measurements would be 36″ x 36″.
- Diagonal Corner Cabinets: Measure the width of the cabinet from the front corner to the edge along each adjacent wall.
Sink Base Cabinets:
These cabinets are designed to house a kitchen sink.
- Width: Measure the width of the cabinet box. For sink base cabinets, you’ll need to know the width of your sink to ensure it fits.
- Depth: Measure the depth of the cabinet box.
- Consider Plumbing: Ensure you have enough clearance for plumbing behind the sink.
Refrigerator Wall Cabinets:
These are often wider cabinets designed to surround a refrigerator.
- Measure the overall width, height, and depth of the space where the refrigerator will be. Include any surrounding cabinet structures.
Determining Cabinet Space and Layout
Beyond measuring individual cabinets, it’s important to measure the entire kitchen space to plan your layout effectively and understand how your cabinets will fit. This involves determining cabinet space for both wall and base cabinets.
Measuring Wall Space:
- Horizontal Measurement: Measure the total length of each wall where cabinets will be installed.
- Vertical Measurement: Measure the height from the countertop to the ceiling or the underside of any upper cabinets/shelving.
- Obstructions: Note the location and size of windows, doors, vents, electrical outlets, switches, and plumbing. These will affect where cabinets can be placed.
Measuring Floor Space:
- Kitchen Footprint: Measure the length and width of the entire kitchen floor area.
- Appliance Locations: Mark the dimensions and placement of existing or planned appliances like the refrigerator, dishwasher, and stove.
Understanding Standard Kitchen Cabinet Sizes
While custom cabinets offer limitless possibilities, knowing standard kitchen cabinet sizes is beneficial, especially for budget-conscious renovations or when working with pre-made units.
Common Standard Sizes:
- Wall Cabinets:
- Widths: 9″, 12″, 15″, 18″, 21″, 24″, 27″, 30″, 33″, 36″, 42″, 48″
- Heights: 12″, 15″, 18″, 24″, 30″, 36″, 42″
- Depths: 12″, 15″ (standard is usually 12″)
- Base Cabinets:
- Widths: 9″, 12″, 15″, 18″, 21″, 24″, 27″, 30″, 33″, 36″, 42″, 48″
- Heights: 34.5″ (without countertop)
- Depths: 24″ (standard is usually 24″)
- Sink Base Cabinets:
- Widths: Typically start at 30″ and go up to 60″ or more to accommodate various sink sizes. The width will be dictated by the sink.
- Heights: 34.5″
- Depths: 24″
Note: These are general guidelines. Always confirm specific dimensions with the manufacturer.
Working with Custom Kitchen Cabinet Measurements
When you opt for custom kitchen cabinet measurements, you have more flexibility, but the measuring process becomes even more critical.
Custom Cabinet Considerations:
- Precise Fit: Custom cabinets are built to your exact specifications. Even a slight error in measurement can result in a cabinet that doesn’t fit.
- Material and Style: Your measurements will inform the size and placement of doors, drawer fronts, and cabinet boxes, influencing the overall aesthetic.
- Professional Consultation: For custom cabinets, it’s often wise to have a professional designer or installer take the measurements. They have the experience to account for subtle nuances in your kitchen’s structure.
Tips for Accurate Measuring
Follow these tips to ensure your measurements are as accurate as possible.
Measurement Best Practices:
- Measure Twice, Order Once: This old adage is particularly true for kitchen cabinets.
- Measure from the Wall: For base cabinets, measure from the wall to the front edge of the cabinet box.
- Measure from the Studs (if exposed): If you’re working with an unfinished space, measure from stud to stud for width.
- Account for Grout Lines and Tile: When measuring existing cabinets, factor in any tile or backsplash that might affect the overall dimensions.
- Use the Same Unit of Measurement: Stick to either inches or centimeters for all your measurements.
- Document Everything: Keep a detailed diagram of your kitchen with all measurements clearly labeled.
- Take Photos: Photos of your existing cabinets can be helpful when discussing your project with suppliers or installers.
Common Measuring Mistakes to Avoid
Being aware of common errors can help you prevent them.
Potential Pitfalls:
- Measuring Over Existing Countertops: Always measure the cabinet box itself, not the top surface with the countertop included, unless specifically for ordering countertop-inclusive units.
- Ignoring Obstructions: Failing to note windows, doors, pipes, or electrical outlets can lead to cabinets that don’t fit or function properly.
- Not Measuring Door/Drawer Gaps: For existing cabinets, if you’re not replacing the entire unit, measure the gaps between doors and drawers to ensure consistent styling.
- Assuming Uniformity: Not every kitchen is perfectly square. Measure each wall and cabinet location individually.
- Forgetting Base Cabinet Height: Remember that the 34.5″ standard height for base cabinets is before the countertop is added.
Frequently Asked Questions (FAQ)
Q1: Do I need to measure the inside of my cabinets?
A1: Generally, no. Unless you have very specific needs for internal organizers or shelves, you’ll primarily be measuring the exterior dimensions for ordering new cabinets. However, knowing the internal dimensions can be helpful for determining cabinet space for specific items.
Q2: What if my kitchen walls are not straight?
A2: This is common! Measure the cabinet location at several points along its width and use the smallest measurement. When installing new cabinets, installers will use shims to compensate for uneven walls.
Q3: How do I measure for a cabinet that fits into a corner?
A3: For L-shaped corner cabinets, measure the width along each wall from the corner. For diagonal corner cabinets, measure the front edge width.
Q4: Should I include the toe kick in my base cabinet width measurement?
A4: No, measure the cabinet box width. The toe kick is usually a separate component or part of the cabinet frame’s projection.
Q5: What is a typical cabinet depth for wall cabinets?
A5: The standard depth for wall cabinets is usually 12 inches. However, you can find shallower or deeper options depending on your needs and space.
Q6: How much space should be between the countertop and the wall cabinets?
A6: The standard space between the countertop and the bottom of wall cabinets is typically 18 inches. This allows for comfortable working space and accommodates most common backsplash heights.
Q7: Do I need to measure my appliances before ordering cabinets?
A7: Yes, absolutely. You need to know the dimensions of your refrigerator, dishwasher, and stove to ensure your cabinets are sized correctly around them. This is crucial for appliance garages, filler panels, and overall kitchen flow.
Q8: What’s the difference between overlay and inset cabinet doors in terms of measurement?
A8: For overlay doors, you measure the door’s actual dimensions, and they overlap the cabinet frame. For inset doors, you measure the cabinet opening precisely, and the doors fit within it. When ordering overlay doors, you typically specify the opening size and the desired overlay amount.
By following this comprehensive guide, you can confidently measure your kitchen cabinets, paving the way for a smoother and more successful renovation experience. Accurate measurements are the foundation of a beautiful and functional kitchen.
