What are the crucial steps in measuring for kitchen cabinets? The crucial steps involve taking precise measurements of your kitchen walls, noting the location of windows, doors, plumbing, and electrical outlets, and then calculating the exact cabinet dimensions needed for each section. This guide will walk you through the entire process, ensuring your new cabinets fit perfectly.
When you’re ready to update your kitchen with new cabinets, the most important first step is accurate measurement. Getting your kitchen cabinet measurements right is the foundation for a successful renovation. Incorrect measurements can lead to delays, costly mistakes, and frustration. This comprehensive, step-by-step guide will help you confidently tackle measuring for cabinets yourself, whether you’re buying pre-made units or planning custom builds. We’ll cover everything from wall lengths to intricate details like cabinet opening size.
Preparing Your Workspace
Before you grab your measuring tape, take some time to prepare your kitchen. A clear, organized space makes measuring much easier and more accurate.
Clearing the Area
- Remove everything from countertops: This ensures you have unobstructed access to the wall and countertop edge.
- Empty lower cabinets: If possible, empty the base cabinets. This isn’t strictly necessary for wall measurements but is helpful if you need to measure existing cabinet depths or clearances.
- Move small appliances: Temporarily relocate any small appliances like toasters, microwaves, or coffee makers that might be in the way.
Gathering Your Tools
Having the right tools makes the job much smoother.
- Measuring Tape: A good quality, retractable metal measuring tape is essential. A longer tape (25 feet or more) is helpful for longer walls.
- Pencil and Paper or Digital Device: For recording your measurements. It’s a good idea to have a clipboard or a flat surface to write on.
- Notepad or Graph Paper: Graph paper is excellent for drawing a simple layout of your kitchen.
- Level: A level helps ensure you’re measuring straight lines, especially when checking wall plumbness.
- Helper (Recommended): Having a second person to hold the end of the tape measure, especially for longer runs, significantly improves accuracy.
Measuring Your Kitchen Walls
This is where the bulk of your measuring work will happen. Accuracy is paramount here.
Step 1: Measure All Wall Lengths
- Start in a corner and measure from one wall to the next.
- Measure at the baseboard or where the wall meets the floor. This is generally the most accurate starting point for cabinet placement.
- Record each wall length precisely. For example, “Wall 1: 120 inches,” “Wall 2: 84 inches.”
Step 2: Account for Obstructions
This is a critical part of measuring for cabinets. You need to know where you can’t put cabinets and how much space those obstructions take up.
- Windows: Measure the width of the window opening. Also, measure the distance from the floor to the bottom of the window (this is crucial for base cabinet depth clearance) and the distance from the top of the window to the ceiling (important for upper cabinet height planning). Note the distance from the corner to the window and from the window to the next corner.
- Doors: Measure the width of the door opening. Note the distance from the floor to the bottom of the door, and importantly, the swing of the door. You need to ensure cabinets don’t interfere with the door opening fully. Measure the distance from the corner to the door and from the door to the next corner.
- Plumbing: Locate all water supply lines and drains. Note their exact positions on the wall. This is especially important for sink base cabinets.
- Electrical Outlets and Switches: Mark the location and height of all outlets and switches. You’ll need to plan cabinet placement around these. If you’re moving outlets, discuss this with an electrician.
- Vents and Radiators: Note the location and size of any heating or cooling vents, and radiators. You’ll need to ensure cabinets don’t block airflow.
- Ceiling Height: Measure the ceiling height in various spots, as it can sometimes vary. This is important for determining the upper cabinet height.
Step 3: Identify Load-Bearing Walls and Other Features
- Load-Bearing Walls: While not directly impacting cabinet measurement, if you plan any significant structural changes, like removing a wall, you’ll need to consult a professional to identify load-bearing walls.
- Bulkheads and Soffits: These are the dropped sections of ceiling often found above cabinets. Measure their depth and height accurately. You’ll need to account for these when planning your upper cabinet heights.
- Pipes and Ducts: Look for any visible pipes or ducts that might intrude into your cabinet space. Measure their dimensions and locations.
Measuring Existing Cabinetry (If Applicable)
If you’re replacing existing cabinets, you’ll want to measure them to get a sense of standard cabinet dimensions and how they fit your space.
Measuring Base Cabinets
- Width: Measure from the outside edge of one cabinet to the outside edge of the next. If you have a single base cabinet, measure its width.
- Depth: Measure from the front of the cabinet face frame to the back. Standard base cabinet depth is usually around 24 inches (not including the countertop).
- Height: Measure from the floor to the top of the cabinet box (before the countertop). Standard height is usually around 34.5 inches.
- Opening Size: For specific appliances like a dishwasher or trash pull-out, measure the cabinet opening size precisely.
Measuring Upper Cabinets
- Width: Measure the width of each upper cabinet.
- Depth: Measure from the wall to the front of the cabinet. Standard upper cabinet depth is usually around 12 inches.
- Height: Measure from the top of the cabinet box to the bottom.
- Upper Cabinet Height: Crucially, measure the distance from the top of your base cabinets (or countertop) to the ceiling or any obstruction like a soffit. This will dictate your upper cabinet height. Standard upper cabinets are often 30, 36, or 42 inches high.
Sketching Your Kitchen Layout
A visual representation is invaluable.
Creating a Floor Plan
- Draw a simple outline of your kitchen: Use graph paper and draw your walls to scale.
- Add in all obstructions: Mark the exact locations and dimensions of windows, doors, plumbing, outlets, vents, and bulkheads.
- Mark wall lengths: Label each wall with its precise measurement.
Marking Cabinet Locations
- Place your proposed cabinets on the plan: Start with large items like the sink base and refrigerator.
- Measure the linear feet of each wall: This helps you understand the total cabinet space you can utilize.
- Consider clearances: Ensure you have adequate space for appliance doors to open, walkways, and seating areas.
Calculating Cabinet Sizes
Now, translate your wall measurements into cabinet sizes.
Base Cabinet Calculations
- Wall Runs: For a continuous run of base cabinets, start with the total wall length and subtract any un-cabineted areas (like for a dishwasher or refrigerator). Divide the remaining length into sections that correspond to standard cabinet widths (e.g., 30 inches, 36 inches).
- Corner Cabinets: These are tricky. You’ll need to decide on a corner cabinet style (e.g., lazy susan, blind corner) and measure the wall lengths leading into the corner. This determines the “face” dimensions of the corner cabinet.
- Toe Kick Space: Remember that standard base cabinets have a toe kick recess at the bottom. This is typically about 3 inches high and 4 inches deep.
Upper Cabinet Calculations
- Wall Runs: Similar to base cabinets, measure wall runs and divide into sections based on standard upper cabinet widths.
- Backsplash Height: The distance between the countertop and the bottom of your upper cabinets (the backsplash area) is crucial. Standard backsplash height is often 18 inches, but this can vary. Ensure your upper cabinet height plus this backsplash height doesn’t exceed your wall height or hit an obstruction.
- *Pantry Cabinet Size*: If you’re planning a tall pantry cabinet, measure the full wall height available, subtract the toe kick space, and account for any header or crown molding space. This will determine the overall height of your pantry cabinet size**.
Essential Measurements for Cabinet Components
Beyond the overall cabinet, specific measurements are key for hardware and functionality.
Cabinet Door Size
- Overlay: This refers to how much the cabinet door covers the cabinet frame. Full overlay doors cover almost the entire frame, while partial overlay doors leave some of the frame visible. Your measurement will depend on the overlay style you choose.
- Hinges: If you’re reusing hinges or buying new ones, you’ll need to measure the hinge type and the cabinet opening size where the hinge mounts.
Drawer Slide Measurements
- Drawer Box Width: The width of the drawer box itself will determine the drawer slide measurements you need. Slides are typically specified by their length and load rating.
- Cabinet Interior Width: You’ll need to know the interior width of the cabinet carcass to fit the drawer slides.
Final Checks and Considerations
Before you finalize your order, do a thorough review.
Double-Checking Measurements
- Measure twice, order once. This old adage is especially true for cabinetry.
- Have someone else check your measurements: A fresh pair of eyes can catch mistakes.
- Confirm all dimensions: Ensure you’ve accounted for every inch of wall space and every obstruction.
Standard Cabinet Sizes vs. Custom
- Standard Sizes: Most cabinet manufacturers offer a range of standard widths (e.g., 9″, 12″, 15″, 18″, 21″, 24″, 27″, 30″, 33″, 36″). Base cabinets typically come in 24″ depth, and upper cabinets in 12″ depth. Base cabinets are usually 34.5″ high (before countertop), and upper cabinets have varying heights.
- Custom Sizes: If your measurements don’t align with standard sizes, you may need custom cabinets. Be prepared for a higher cost and longer lead time.
Considering Installation Measurements
- Cabinet Installation Measurements: Beyond the initial layout, think about the actual installation. You’ll need to account for shims to ensure cabinets are level and plumb. This means having a little extra wiggle room, not exact wall-to-cabinet measurements that are too tight.
- J-boxes for lighting: If you plan under-cabinet lighting or recessed lighting, note the location of electrical junction boxes.
Common Pitfalls to Avoid
Being aware of these common mistakes can save you a lot of trouble.
- Not accounting for door swings: Ensure cabinets don’t block essential doors.
- Ignoring obstructions: Overlooking a vent or outlet can be a costly oversight.
- Measuring from the wrong point: Always measure from a consistent reference, like the floor or the edge of an existing cabinet.
- Not allowing for plumbing or electrical rough-ins: If you’re moving utilities, get the final rough-in measurements before ordering cabinets.
- Assuming walls are perfectly straight or plumb: Walls can bow in or out. Use a level and measure at multiple points.
- Forgetting about appliance clearances: Refrigerators, dishwashers, and ovens need specific clearances to function correctly.
Frequently Asked Questions (FAQ)
Q: How accurate do my kitchen cabinet measurements need to be?
A: Your measurements need to be highly accurate, down to the 1/8th of an inch. Even small errors can significantly impact the fit and appearance of your new cabinets.
Q: What if my walls aren’t perfectly straight?
A: Most walls have some imperfection. Measure at several points along the wall and use the smallest measurement. You can use shims during installation to account for minor deviations. Always use a level during the installation process to ensure cabinets are plumb and level.
Q: Do I need to measure the inside of my existing cabinets?
A: It’s helpful to measure the inside of existing cabinets for reference, especially for drawer slide measurements or to see how certain components were installed. However, the most critical measurements are of the walls and obstructions where the new cabinets will go.
Q: What is a standard base cabinet depth?
A: A standard base cabinet depth is typically 24 inches. This measurement is for the cabinet box itself and does not include the countertop, which will add an additional 1.5 to 2 inches.
Q: How do I determine the correct upper cabinet height?
A: The upper cabinet height is determined by the distance between your countertop (or base cabinets) and the ceiling or any soffits or bulkheads. You must subtract standard backsplash height (often 18 inches) from this total wall height to find the maximum possible height for your upper cabinets.
Q: What should I do about corner cabinets?
A: Corner cabinets require careful planning. Measure the lengths of both walls that meet at the corner. You’ll then need to choose a corner cabinet style (like a lazy susan or a blind corner cabinet) and its specific cabinet dimensions will be based on these wall measurements.
By following these detailed steps, you can confidently measure your kitchen for new cabinets. Accurate kitchen cabinet measurements are the cornerstone of a beautiful and functional kitchen renovation. Happy measuring!
