How to Measure Your Kitchen for New Cabinets
Accurate cabinet measurements are the hinge on which every successful kitchen remodel swings. A tape-measure error of even ⅛ inch can snowball into crooked fillers, mis-hung doors, or countertops that don’t seat flush against the wall. This guide walks you through the exact steps for measuring your Florida kitchen like a pro. It covers the tools you’ll need, NKBA-recommended clearances, standard cabinet dimensions, and smart tips for squaring up rooms that humidity has nudged out of plumb. Follow the sequence and you’ll hand your designer rock-solid numbers that prevent expensive re-orders and weeks of project delays.
Why Getting It Right Matters
Standard base cabinets are 34½ inches tall and 24 inches deep, dimensions that set the height of every other surface in the kitchen. If your linear footage is off by just an inch, the factory can’t cut toe-kicks, fillers, or countertops accurately, and installers will spend billable hours scribing parts on-site. Precise measurements also reveal walls that bow or floors that slope, a common issue in older Gulf-Coast homes where humidity swells the framing lumber. Catching those quirks early allows you to order shims and trim kits instead of wasting lead time on unexpected fixes.
Gather Your Tools
- 25-foot steel tape
- 6-foot level (or laser level)
- Pencil, blue painter’s tape, fine-tip marker
- Graph paper
- Straightedge or ruler
- Smartphone or camera for reference photos
Most national retailers provide free downloadable worksheets you can print on letter paper to sketch the space
The Step-by-Step Measurement Process
Create a Rough Floor-Plan Sketch
Stand in the doorway and hand-draw each wall in clockwise order. Don’t worry about scale yet; note doors, windows, radiators, soffits, and obstructions.
Record Overall Wall Lengths
Measure wall A from the left corner to the right. Write the number both on your sketch and on a piece of blue tape stuck to that wall so you don’t mix up readings later
Measure Ceiling Height
The standard ceiling height is 96 inches, but remodels often reveal surprises—bulkheads and older homes may vary by an inch either way. Record the distance from the finished floor to the finished ceiling in at least three locations.
Document Doors and Windows
For each opening, record the width, height, and distance from the nearest corner or intersecting wall. Note the swing direction of the doors so that new drawers don’t collide.
Capture Appliance Footprints
Your fridge, range, and dishwasher dictate minimum cabinet clearances. The NKBA recommends at least 15 inches of landing space on both sides of a cooktop and 18 inches on the pull side of a refrigerator. Measure appliance width, depth (including handles), and ventilation requirements.
Locate Utilities
Mark the centerlines of sink plumbing, gas lines, and electrical outlets. Measure from the same datum—usually the left corner of the wall—to maintain consistency
Verify Squareness
Take diagonal measurements from opposite corners of each wall segment; equal diagonals confirm that the shape is a square. If numbers differ, flag that wall as out of square so filler strips can be ordered. Use a 6-foot level to check floors for slope.
Photograph Everything
Snap photos of each wall with the tape visible on key dimensions. Installers rely on these images when interpreting hand-drawn plans
Common Measurement Mistakes to Avoid
- Measuring unfinished framinginstead of finished drywall—wait until the walls are closed.
- Reading the tape upside-down—double-check every number.
- Ignoring trim thickness, baseboard, and window casing eat into cabinet clearances
- Forgetting ceiling obstructionslike pendant lights or HVAC grilles.
- Rounding numbers—record to the nearest 1⁄16 inch; the factory will do any needed rounding.
Converting Measurements Into a Cabinet Plan
Transfer field numbers onto graph paper, using one square to represent either three or six inches. Add annotations for appliance landing areas in accordance with NKBA guidelines. Highlight any walls that are more than ⅛ inch out of square; your designer will adjust the fillers accordingly. Finally, total each cabinet run in linear feet to obtain a starting quote—many retailers price doors and drawers by the foot.
When to Bring in the Pros
If your home is more than 30 years old, expect at least one wall to lean out of plumb due to framing settlement or seasonal moisture. Professional measurers use laser transits to map inconsistencies down to 1⁄32 inch and can set finished-height targets for countertops relative to sloping floors. In coastal zones, they also inspect for hidden water damage behind sink bases—an early warning that replacement boxes, rather than refacing, may be a smarter option.
Final Thoughts & Next Steps
Meticulous measuring sets the foundation for flawless Florida cabinet installations. With the numbers in hand—and a smartphone album full of reference photos—you’ll empower your designer to draft accurate elevations, order the right fillers and panels, and coordinate countertop templating without the need for costly back-and-forth.
