What is the best way to measure kitchen cabinets? The best way is to be thorough and meticulous, measuring every inch of the space where your cabinets will go, including height, width, and depth. This comprehensive guide will help you achieve perfect cabinet measurements for your kitchen renovation or new build. Accurate cabinet dimensions are crucial for everything from ordering stock cabinets to getting precise quotes for custom cabinet measurements.
Why Precise Measurement Matters
Getting your cabinet measurements right is the bedrock of a successful kitchen project. When you are measuring for cabinets, even a small error can lead to significant problems down the line. Imagine ordering beautiful new cabinets, only to find they don’t fit the space as intended. This could mean costly returns, delays, or even the need for custom adjustments that weren’t in your initial budget.
The Impact of Inaccurate Measurements
- Wasted Money: Incorrect cabinet dimensions can lead to buying too much or too little material, requiring you to purchase more or dealing with unusable pieces.
- Installation Headaches: Cabinets that are too big, too small, or oddly shaped will make cabinet installation measurements a nightmare. This can increase labor costs and frustration for your installer.
- Aesthetic Compromises: Poorly fitting cabinets can disrupt the visual flow and functionality of your kitchen, making it look cluttered or unfinished.
- Appliance Fit Issues: Incorrect measurements can prevent your appliances, like refrigerators or dishwashers, from fitting flush or operating correctly.
Gathering Your Tools
Before you even think about touching a tape measure, ensure you have the right tools. Having the correct equipment will make the process smoother and more accurate.
- Metal Tape Measure: A sturdy metal tape measure is essential. Avoid fabric tapes as they can stretch. Ensure it has a lock feature to hold your measurement.
- Paper and Pencil/Pen: For recording your measurements. It’s wise to have extra paper on hand.
- Notebook or Clipboard: To keep your measurements organized.
- A Helper: Having someone to hold the end of the tape measure can prevent inaccuracies, especially for longer spans.
- Level: To ensure your measurements are taken from true vertical and horizontal lines, which is critical for accurate cabinet installation measurements.
- Optional: Laser Measure: For very large spaces or hard-to-reach areas, a laser measure can be a useful addition, but always double-check with a manual tape measure.
Measuring Your Kitchen Space: A Step-by-Step Guide
This is where the real work begins. We’ll break down the process of taking cabinet measurement guide for your kitchen, covering all essential aspects.
Measuring Existing Cabinets (If Applicable)
If you are replacing existing cabinets, you can use them as a starting point. However, always measure your space, not just the cabinets. Cabinet boxes can sometimes be slightly smaller than the overall footprint they occupy.
How to Measure Existing Cabinet Boxes:
- Cabinet Width: Measure the front of the cabinet box from the left edge to the right edge.
- Cabinet Height: Measure from the bottom of the cabinet box to the top.
- Cabinet Depth: Measure from the front of the cabinet box to the back. Don’t forget to account for any face frames or doors that extend beyond the box itself.
Important Note: When ordering new cabinets, you’ll typically order based on the cabinet dimensions of the space you want to fill, not necessarily the exact cabinet dimensions of your old, existing cabinets.
Measuring Your Kitchen Walls for New Cabinets
This is the most critical part of measuring for cabinets. You need to capture the precise dimensions of the walls where your cabinets will be placed.
Step 1: Wall Width
This refers to the total length of the wall where you plan to install cabinets.
- How to Measure:
- Start at one corner of the wall.
- Extend your tape measure to the opposite corner.
- Record this measurement.
- Crucially, measure the width in at least three places: at the floor, at the typical countertop height (around 36 inches), and near the ceiling. Walls are rarely perfectly straight. Take the smallest of these measurements. This ensures your cabinets will fit without any gaps.
- Also, note any existing features on the wall that will affect cabinet placement, such as windows, doors, vents, electrical outlets, or plumbing fixtures. Measure the distance from the corner to these features.
Step 2: Wall Height
This is the vertical measurement from the floor to the ceiling.
- How to Measure:
- Place one end of your tape measure at the floor in the corner where you’ll start your cabinet run.
- Extend the tape measure straight up to the ceiling.
- Record this measurement.
- Like width, measure the height in a few different spots along the wall, especially where cabinets will be installed. Ceilings can have slight variations. Use the shortest height measurement for your calculations to ensure your upper cabinets don’t hit the ceiling.
Step 3: Cabinet Depth Considerations
While you measure the wall space, you also need to think about the depth of your cabinets.
- Standard Cabinet Depth: Most base cabinets have a standard depth of 24 inches (for the box) plus about 1-1.5 inches for the door/drawer front and countertop overhang. Wall cabinets typically have a depth of 12 inches.
- Obstructions: Measure the depth of any obstructions that might interfere with your cabinet placement. This could include protruding pipes, electrical boxes, or existing windowsills.
- Measure from the wall to the front of the obstruction. This tells you the maximum cabinet depth you can accommodate.
Step 4: Measuring for Appliances
The placement and dimensions of your appliances are integral to your cabinet layout.
- Refrigerator:
- Measure the width, height, and depth of the appliance itself.
- Also, measure the clearance needed around the refrigerator for ventilation and to allow the doors to open fully.
- Dishwasher:
- Measure the standard width (usually 24 inches, but 18-inch models exist).
- Measure the height and depth, paying attention to where the plumbing and electrical connections are.
- Range/Oven:
- Measure the width, height, and depth of the unit.
- Note the location of gas or electrical hookups.
- Consider the required clearances around the cooktop for heat and ventilation.
Step 5: Windows and Doors
These architectural features significantly impact where and how cabinets can be placed.
- Window Measurements:
- Width: Measure the width of the window opening.
- Height: Measure the height from the windowsill to the top of the window opening.
- Distance from Corners: Measure the distance from each adjacent corner to the edge of the window opening.
- Sill Depth: Measure the depth of the windowsill. This is important if you plan for a countertop to extend to the window.
- Door Measurements:
- Width: Measure the width of the door opening.
- Height: Measure the height from the floor to the top of the door frame.
- Distance from Corners: Measure the distance from each adjacent corner to the edge of the door frame.
- Door Swing: Note which way the door swings and if it will interfere with cabinet placement.
Step 6: Obstructions and Utilities
You must account for anything that might get in the way of your cabinets.
- Outlets and Switches: Measure their exact location on the wall (height from the floor and distance from the corner). This is crucial for cabinet installation measurements to ensure your cabinets don’t cover them.
- Vents and Grilles: Measure their size and location. You may need to plan cabinet sections around them or consider relocating them.
- Plumbing: Note the location of sink drains, water supply lines, and any other plumbing that might affect base cabinet placement.
- Radiators: Measure their height, width, and depth, as they will likely require clearance or custom cabinetry solutions.
Calculating Your Cabinet Needs
Once you have all your raw measurements, it’s time to translate them into cabinet orders. This is where understanding kitchen cabinet sizes and how to plan your layout comes in.
Base Cabinets
Base cabinets sit on the floor and typically support a countertop.
- Measuring for Base Cabinets:
- Wall Width: Take your wall width measurements and divide them by standard cabinet widths (e.g., 12″, 15″, 18″, 21″, 24″, 30″, 36″). Remember to account for corner cabinets.
- Corner Cabinet Planning: Kitchen corners are tricky.
- Blind Corner: If you have a run of cabinets that ends at a corner with no other cabinets on the adjacent wall, you’ll likely use a “blind corner” cabinet. These have a wider opening on one side, with a “filler” panel on the other. You need to measure the total width of both walls that meet at the corner to determine the correct blind corner cabinet size.
- Lazy Susan/Corner Carousel: If you have cabinets on both walls meeting at a corner, you might use a corner lazy susan or a corner sink base cabinet. Measure the total width along each wall leading into the corner to determine the size needed for these specialized units.
- Appliance Alcoves: If you are installing a dishwasher or range, you will need specific sized cabinet openings for them. Measure the appliance and add a small amount of clearance (e.g., 1/4 inch) for installation.
- Sink Base Cabinet: This is a crucial cabinet. Measure the width of your sink and add space for plumbing and cabinet support. Standard sink base cabinets are often 3 inches wider than the sink itself.
Wall Cabinets
Wall cabinets are mounted above countertops.
- Measuring for Wall Cabinets:
- Wall Width: Similar to base cabinets, use your wall width measurements and divide by standard cabinet widths.
- Vertical Space: You need to decide on the cabinet height you want.
- Standard Heights: Wall cabinets come in common heights like 30″, 36″, and 42″.
- Countertop to Ceiling: Measure the distance from your countertop to the ceiling. Subtract your desired cabinet height and any necessary filler space above the cabinet. This will tell you if your chosen height fits.
- Standard Wall Cabinet Height: Most people aim for upper cabinets to reach within a few inches of the ceiling, or have a bulkhead above them.
- Clearance Above Countertop: The standard clearance between a base cabinet countertop and the bottom of a wall cabinet is 18 inches. Measure this space accurately, noting any exceptions due to windows or other obstructions.
- Cabinet Depth: Standard wall cabinet depth is usually 12 inches. Ensure this depth doesn’t interfere with windows or other wall features.
Standard vs. Custom Cabinet Measurements
Understanding the difference is key to making informed decisions.
-
Standard Cabinet Sizes: Most manufacturers offer a range of standard cabinet sizes in increments (often 3 inches). This makes them more affordable and readily available. However, they might not perfectly fit every space, potentially leaving awkward gaps or requiring fillers.
- Common Base Cabinet Widths: 9″, 12″, 15″, 18″, 21″, 24″, 27″, 30″, 33″, 36″
- Common Base Cabinet Depths: 24″ (box)
- Common Base Cabinet Heights: 34.5″ (to fit standard 36″ countertop height)
- Common Wall Cabinet Widths: 12″, 15″, 18″, 21″, 24″, 27″, 30″, 33″, 36″
- Common Wall Cabinet Depths: 12″
- Common Wall Cabinet Heights: 18″, 30″, 36″, 42″
-
Custom Cabinet Measurements: For kitchens with unusual layouts, unique appliance needs, or very specific aesthetic desires, custom cabinets are the way to go. Custom cabinet measurements allow for cabinets to be built to exact dimensions, maximizing storage and ensuring a seamless fit.
- Benefits of Custom: Perfect fit, tailored storage solutions, unique design possibilities.
- Considerations for Custom: Higher cost, longer lead times, requires precise measurements provided by you or a professional.
Creating a Measurement Diagram
A visual representation of your measurements is invaluable.
- Sketch Your Kitchen Layout: Draw a bird’s-eye view of your kitchen. Include all walls, doorways, windows, and appliance locations.
- Add Measurements: On your sketch, carefully label all the dimensions you’ve taken: wall lengths, heights, distances from corners to windows/doors/outlets, appliance dimensions, and any obstruction measurements.
- Mark Cabinet Locations: Indicate where you envision your base cabinets, wall cabinets, and any special units (like sink bases or corner cabinets) to go.
- Use a Scale (Optional but Recommended): Drawing to scale can help you visualize the space better, but ensuring accurate numerical labels is paramount.
Example Measurement Diagram Elements:
- Wall 1: 120 inches (from corner A to corner B)
- Window: 36 inches wide, starts 30 inches from corner A, ends 66 inches from corner A. Sill height 34 inches.
- Outlet: 48 inches from corner A, 48 inches from floor.
- Wall 2: 96 inches (from corner B to corner C)
- Range: 30 inches wide, centered on the wall. Requires 6 inches clearance on each side.
- Base Cabinet Run: 66 inches available next to the range.
Common Pitfalls to Avoid
Even with the best intentions, mistakes can happen. Here are some common traps to sidestep:
- Not Measuring Walls in Multiple Spots: Assuming walls are perfectly straight is a common error. Always check for bowing or out-of-plumb conditions.
- Forgetting About Obstructions: Small things like electrical boxes, pipes, or radiator valves can throw off your entire plan if missed.
- Not Accounting for Door Swings: Ensure that your cabinet doors, appliance doors, and entry doors don’t collide.
- Ignoring Appliance Clearances: Refrigerators and ovens need space to breathe and operate. Factor this in.
- Not Measuring Existing Structures Precisely: If you’re working around existing features, measure them accurately.
- Rushing the Process: Take your time. Accuracy is more important than speed.
- Not Double-Checking: Measure, then measure again. A second pair of eyes can be helpful.
Frequently Asked Questions (FAQ)
Q1: Do I need to measure the inside or outside of my cabinets?
A: When planning a kitchen, you measure the space where cabinets will go, focusing on wall dimensions (width, height) and any obstructions. If you’re measuring existing cabinets to replicate them, you’d measure the outer box dimensions.
Q2: What is the standard space between base cabinets and wall cabinets?
A: The standard clearance between the countertop of base cabinets and the bottom of wall cabinets is 18 inches.
Q3: What if my wall measurements aren’t standard sizes?
A: If your wall dimensions don’t perfectly align with standard cabinet sizes, you have two main options:
1. Use fillers: These are thin strips of wood that can fill small gaps between cabinets or between a cabinet and a wall.
2. Consider custom cabinets: For a truly seamless fit in non-standard spaces, custom cabinet measurements ensure every inch is utilized perfectly.
Q4: How do I measure for corner cabinets?
A: For corner cabinets, you need to measure the linear footage of both walls that meet at the corner. This helps determine the size of the corner cabinet unit (e.g., a lazy susan cabinet or a blind corner cabinet).
Q5: What’s the most important measurement to get right?
A: All measurements are important, but wall width and height are critical for ensuring cabinets fit the overall space. Precise measurements of windows, doors, and obstructions are also vital to avoid installation problems.
