How to Measure for Kitchen Cabinets: Step-by-Step Guide
What is the most crucial step before ordering kitchen cabinets? The most crucial step before ordering kitchen cabinets is accurately measuring your kitchen space. This ensures you order the correct sizes, avoid costly mistakes, and streamline the cabinet installation process.
Embarking on a kitchen renovation is an exciting endeavor, and one of the most critical phases is ensuring your new cabinets fit perfectly. Accurate kitchen renovation measurements are the bedrock of a successful kitchen makeover. Get them wrong, and you could face delays, increased costs, and a frustrating cabinet installation. This comprehensive guide will walk you through the essential steps of DIY cabinet measuring, ensuring your project goes smoothly from start to finish.
Preparing for Your Measurements
Before you even pick up a tape measure, some preparatory steps will make your measuring process far more efficient and accurate.
Gathering Your Tools
You’ll need a few essential tools for precise kitchen cabinet dimensions:
- Tape Measure: A sturdy, retractable tape measure is your primary tool. Aim for one that’s at least 25 feet long.
- Pencil and Paper: For jotting down all your measurements. A clipboard can be helpful to keep everything organized.
- Graph Paper (Optional but Recommended): This allows you to sketch out your kitchen’s layout and label measurements clearly.
- Level: To check if walls are plumb and floors are level, which can affect cabinet placement.
- Calculator: For any quick calculations you might need to do.
- Helper (Recommended): Having a second person can make measuring walls and awkward spaces much easier and more accurate.
Understanding Your Kitchen Space
You need to measure kitchen space thoroughly, noting not just the obvious dimensions but also potential obstructions and key features.
- Wall Lengths: Measure each wall where cabinets will be installed.
- Window and Door Locations and Sizes: Mark the exact position and dimensions of all windows and doors. Note their height from the floor and their width.
- Appliance Locations: Measure the space for your refrigerator, stove, dishwasher, and any other built-in appliances.
- Plumbing and Electrical Outlets: Note the location of existing plumbing hookups (sink, dishwasher) and electrical outlets.
- Obstructions: Identify anything that might interfere with cabinet placement, such as radiators, vents, soffits, or structural beams.
- Ceiling Height: Measure the distance from the floor to the ceiling. This is crucial for determining cabinet height options.
- Existing Features: Note the location and height of existing features like backsplashes, countertops (if you’re replacing them but keeping the same layout), or anything else that might affect your cabinet layout planning.
Step-by-Step Measuring Process
Now, let’s get down to the actual measuring. Accuracy is paramount.
Measuring Wall Lengths
- Start at a Corner: Begin at one corner of the room.
- Extend the Tape Measure: Stretch the tape measure along the wall to the next corner or significant feature (like a doorway or appliance space).
- Record the Measurement: Write down the measurement accurately. Be precise to the nearest 1/8 inch.
- Measure to Obstructions: If there’s a doorway, window, or appliance space along the wall, measure the distance from the corner to the start of that obstruction, and then from the end of the obstruction to the next feature.
- Repeat for All Walls: Do this for every wall where you plan to install cabinets. It’s a good idea to measure each wall in two places (e.g., at the floor and at waist height) to account for any bowing or irregularities.
Table 1: Example Wall Measurement Sheet
| Wall Identification | Measurement (in.) | Notes |
|---|---|---|
| Wall A (Left of Sink) | 126.5 | 42″ from corner to window start |
| Wall B (Back Wall) | 180.25 | 36″ to doorway, 60″ to window |
| Wall C (Right of Sink) | 98.75 | 24″ for fridge space |
| Wall D (Short Wall) | 60.0 | No obstructions |
Measuring for Windows and Doors
This is critical for cabinet layout planning as cabinets cannot obstruct these openings.
- Width: Measure the width of the window or door opening from stud to stud (or jamb to jamb).
- Height: Measure the height of the opening from the floor to the top of the opening (or header).
- Sill/Header Height: Measure the distance from the floor to the bottom of the window sill and from the top of the door frame to the ceiling.
- Position: Measure the distance from the nearest corner to the edge of the window or door opening.
Measuring for Appliances
Accurate appliance measurements are vital for a seamless fit.
- Refrigerator: Measure the width, height, and depth of the opening the refrigerator will occupy. Also, consider door swing clearance.
- Stove/Range: Measure the width of the space. If it’s a slide-in range, measure the width and depth of the countertop cutout. If it’s a freestanding range, measure the width and depth, and ensure there’s enough clearance for the back.
- Dishwasher: Measure the standard width (typically 24 inches) and height of the opening. Ensure you know the exact rough opening dimensions needed for installation.
Measuring for Cabinets: Depth and Height
When planning your cabinet layout planning, you’ll need to consider standard cabinet depth and cabinet height options, but you also need to measure your space to ensure they fit.
- Cabinet Depth: Standard base cabinets have a cabinet depth of 24 inches (for the box) and a countertop that extends to 25 inches. Wall cabinets typically come in depths of 12 or 15 inches. You need to ensure these depths don’t interfere with walkways or other features. Measure your existing base cabinets if you’re keeping them for reference, but rely on wall measurements for new installations.
- Cabinet Height: Base cabinets are typically 34.5 inches high without a countertop, allowing for a standard 36-inch finished height once a 1.5-inch countertop is added. Wall cabinets come in various heights, such as 30, 36, or 42 inches. Measure the distance from your countertop (or desired countertop height) to the ceiling or soffit to determine the maximum cabinet height you can accommodate. Also, note the height of windowsills and doorways to ensure wall cabinets don’t interfere.
Measuring Ceiling Height and Wall Irregularities
Don’t assume your walls are perfectly straight or your ceiling is perfectly level.
- Ceiling Height Variation: Measure the ceiling height at multiple points along each wall. Note any significant variations. This is important because if your ceiling slopes, you may need to adjust wall cabinet heights or consider custom solutions.
- Wall Plumbness: Use a level to check if your walls are plumb (perfectly vertical). If a wall is out of plumb, it can create gaps between cabinets and the wall, which may need to be addressed during cabinet installation.
Measuring for Countertop Space
While you’re measuring for cabinets, it’s a good time to also take basic countertop measurements.
- Length: Measure the total length of the countertop space you plan to install.
- Depth: Measure the desired cabinet depth that will accommodate the countertop. Standard is 24 inches for the cabinet box.
Creating Your Kitchen Diagram
Once you have all your measurements, it’s time to put them to use.
- Draw a Floor Plan: On graph paper or using design software, draw a scaled floor plan of your kitchen. Include all walls, doors, windows, and permanent fixtures.
- Mark Wall Measurements: Label the exact length of each wall on your diagram.
- Indicate Obstructions: Mark the precise location and dimensions of all windows, doors, and appliances.
- Plan Cabinet Placement: Start sketching where you envision your cabinets going. Consider your workflow, appliance placement, and desired cabinet layout planning. Think about:
- Sink Base Cabinet: Where will the sink go? This dictates plumbing access.
- Range/Cooktop Area: Ensure adequate landing space on either side.
- Refrigerator Placement: Allow for door swing.
- Dishwasher Location: Typically next to the sink.
- Wall Cabinets: How high will they be? Will they go to the ceiling?
- Base Cabinets: Standard cabinet depth is 24 inches.
Special Considerations for Measuring
Some situations require extra attention to detail.
Measuring for Corner Cabinets
Corner cabinets are often tricky. You need to measure the actual corner space.
- Diagonal Measurement: Measure diagonally from one wall to the other where the corner cabinet will sit. This helps determine the cabinet’s “face” measurement.
- Depth Consistency: Ensure you’re measuring the cabinet depth consistently.
Measuring for Islands and Peninsulas
If you’re planning a kitchen island or peninsula, precise measurements are crucial for flow and functionality.
- Clearance: Ensure adequate clearance around the island for walkways (at least 36 inches, ideally 42-48 inches).
- Dimensions: Measure the desired length and width of the island.
Measuring Existing Cabinets (If Refacing or Replacing Doors)
If you’re refacing cabinets or just replacing doors, you need to measure each existing cabinet door and drawer front.
- Door Measurement: Measure the width and height of each door and drawer front. Measure them when they are removed from the cabinet box for the most accurate results.
- Cabinet Box Depth: Note the cabinet depth of the boxes themselves.
Double-Checking Your Measurements
This is arguably the most critical step after the initial measurement.
- Re-measure Everything: Go back and measure every single dimension again.
- Compare Your Notes: Compare the first set of measurements with the second. If there are discrepancies, re-measure until you get consistent numbers.
- Walk Through Your Layout: Mentally (or physically on your diagram) place each cabinet. Does everything fit? Are there any conflicts? Does it allow for comfortable movement?
What to Do With Your Measurements
Once you have accurate kitchen renovation measurements, you can:
- Create a Detailed Cabinet Order List: Use your measurements and cabinet layout planning to create a precise list of the cabinet types, sizes, and configurations you need.
- Get Quotes from Cabinet Suppliers: Provide your detailed measurements and layout to cabinet makers or showrooms.
- Prepare for Installation: Knowing your measurements helps anticipate potential challenges during cabinet installation and allows you to communicate effectively with your installer.
Common Measuring Mistakes to Avoid
Even with the best intentions, mistakes can happen. Being aware of these common pitfalls can help prevent them.
- Not Measuring Wall Lengths in Multiple Places: Walls aren’t always perfectly straight.
- Forgetting Obstructions: Ignoring vents, pipes, or electrical boxes can lead to significant problems.
- Assuming Standard Dimensions: While many things are standard, your kitchen might have unique features.
- Not Accounting for Door Swings: Ensure appliances and doors can open fully without hitting cabinets.
- Inaccurate Diagonal Measurements: Especially critical for corner cabinets.
- Not Measuring Ceiling Height Variations: Can impact wall cabinet placement.
- Rushing the Process: Take your time and be meticulous.
Frequently Asked Questions (FAQ)
Q1: How precise do my measurements need to be?
A1: You need to be as precise as possible, aiming for measurements to the nearest 1/8 of an inch. Even small inaccuracies can lead to problems during cabinet installation.
Q2: Can I measure my old cabinets instead of the walls?
A2: If you are replacing cabinets with identical layouts, you can use old cabinet dimensions as a reference. However, for new cabinet layout planning or if your old cabinets were poorly fitted, it’s always best to measure kitchen space (walls, windows, doors, appliances) directly.
Q3: What if my walls aren’t straight?
A3: If your walls are out of plumb, you may need to account for this during installation. Cabinet installers can often shim cabinets to make them plumb, but knowing the extent of the issue beforehand is crucial. Measure the deviation with a level.
Q4: Do I need to measure for the countertop at the same time?
A4: Yes, it’s highly recommended. Countertop measurements are directly related to cabinet dimensions, especially the overall height and cabinet depth. It’s best to have all these measurements coordinated.
Q5: How do I account for baseboards when measuring for cabinets?
A5: Baseboards can add thickness to the wall. Measure from the corner to the edge of the baseboard, then measure the depth of the baseboard itself. This measurement helps determine how much the cabinet might need to be set out from the wall or if the baseboard needs to be removed. For standard base cabinets, you measure the wall space behind the baseboard, and the cabinet box will typically sit flush with the wall, with the baseboard potentially needing to be trimmed or removed.
Q6: What is the standard kitchen cabinet depth?
A6: Standard base cabinet boxes have a cabinet depth of 24 inches. Wall cabinets commonly come in 12-inch or 15-inch depths.
Q7: How do I measure for a corner cabinet?
A7: You need to measure the dimensions of the wall space where the corner cabinet will sit. Measure the length of each wall segment leading into the corner. The actual cabinet size will be based on these wall measurements and the cabinet’s construction (e.g., a standard lazy susan corner base cabinet might have a 36″ x 36″ face, fitting into a corner where two walls meet).
Accurate measurements are the foundation of a beautiful and functional kitchen. By following these steps diligently, you’ll set yourself up for a successful DIY cabinet measuring project and a smooth cabinet installation, bringing your dream kitchen one step closer to reality.
