One of the most crucial steps in planning a successful kitchen remodel is accurately measuring for your new cabinets. Whether you’re working with a designer or planning a DIY installation, precise measurements are the foundation of your entire project. This guide will walk you through how to measure kitchen cabinets for a remodel to ensure a perfect fit and a smooth installation process. Taking the time to do this correctly can save you from costly errors and significant delays.

Tools You’ll Need
Before you begin, gather a few essential tools:
- A 25-foot metal tape measure
- A notepad and pen or a digital tablet
- A step ladder
- A level to check for wall and floor straightness
Step 1: Sketch Your Kitchen Layout
Start by drawing a rough sketch of your kitchen’s floor plan from a bird’s-eye view. It doesn’t need to be perfect, but it should include all walls, windows, doorways, and any permanent fixtures that will not be moving (like a gas line or plumbing). Label each wall (e.g., Wall A, Wall B) to keep your measurements organized.
Step 2: Measure the Overall Wall Dimensions
Begin by measuring the total length of each wall, from one corner to the other. It’s a good practice to take this measurement at three different heights—near the floor, at countertop height (36 inches), and near the top of where your upper cabinets will be (84 inches). Walls are rarely perfectly straight, and these three measurements will reveal any significant variations. Record the smallest of the three measurements for each wall on your sketch.
Step 3: Mark and Measure Obstructions
Next, you need to locate and measure every item that will interrupt your cabinet runs. This includes windows, doors, pipes, and electrical outlets.
Windows and Doors:
For each window and door, measure from the corner of the wall to the outer edge of the trim. Then measure the width of the window or door itself, including the trim. Finally, measure from the other side of the trim to the next corner. The sum of these three measurements should equal your total wall measurement from Step 2. Also, measure the height of each window from the floor to the bottom of the sill.
Centerlines for Appliances and Plumbing:
You need to mark the centerline of your sink base, range, and refrigerator. Measure from the corner of the wall to the center of the plumbing for your sink, the center of your gas line or 220v outlet for your range, and the center of the water line for your refrigerator. Record these centerlines on your sketch. This is critical for ensuring your new custom kitchen cabinets align perfectly with your utilities.
Step 4: Measure Vertical Space
Measure the total height of your ceiling from the floor. Again, take this measurement in a few different spots in the kitchen, as ceilings can also be uneven. Record the lowest measurement. This will determine the maximum height for your wall cabinets and any tall pantry cabinets. For more tips on maximizing vertical space, consider these floor-to-ceiling cabinetry ideas.
Step 5: Double-Check Everything
Accuracy is paramount. Once you have recorded all your measurements, go back and double-check every single one. It’s helpful to have a second person assist with this step. Confirm that your individual measurements for windows, doors, and centerlines add up to your total wall measurements. Reputable resources like This Old House also offer excellent guides to cross-reference.
Working with a Professional
While taking your own initial measurements is a great way to start planning, it is highly recommended to have a professional kitchen designer verify everything before you place a cabinet order. A professional has the experience to spot potential issues you might miss, such as uneven floors or bowed walls, and they will ensure your final design is both beautiful and functional. A designer can also create a detailed 3D rendering, allowing you to visualize the entire space before making any final decisions.
Frequently Asked Questions
What is the standard height for base and wall cabinets?
Standard base cabinets are 34.5 inches tall (which becomes 36 inches with a countertop). Standard wall cabinets are typically 30, 36, or 42 inches tall, depending on your ceiling height.
How much space should be between the countertop and the bottom of the wall cabinets?
The standard space is 18 inches. This provides ample room for small appliances and workspace.
Do I need to account for the thickness of drywall?
You should always measure from the finished wall surface (the drywall). If you are remodeling down to the studs, your designer will account for the future thickness of the drywall in their final plans.
