How to Measure Your Kitchen Floor for Tile Installation
Measuring your kitchen floor for tile installation sounds like the easy part of the project. Pull out a tape measure, multiply two numbers, and you’re done. But experienced homeowners and WNC flooring contractors know that taking incorrect measurements is one of the most common and costly mistakes in any tile project, especially in small kitchens, where there’s little room for error.
Measuring your kitchen floor for tile installation correctly involves more than basic math. It requires understanding your kitchen’s shape, accounting for waste and cuts, and knowing how your chosen tile size and layout pattern affect the final quantity. Get this step right, and the rest of the project falls into place. Get it wrong, and you’ll either run short of material mid-install or overbuy and lose money on tiles you’ll never use.
This guide walks through the entire measurement process for a small kitchen tile flooring project in Western North Carolina, including tips specific to the irregular layouts and older home construction common throughout Asheville, Hendersonville, Black Mountain, and surrounding communities.
Why Kitchen Tile Measurement Matters More Than You Think
When you’re figuring out how to measure your kitchen floor for tile installation, the stakes are higher than they appear. The box typically sells tile, and each box contains a fixed square footage of material. Order too few and you risk getting tiles from a different production run that won’t match the original exactly in color or shading. Order too much, and you’ve spent money on material sitting in storage.
For small kitchens, precision matters even more. A 90-square-foot kitchen with a diagonal tile layout might need an additional 15-18 square feet of tile just to account for the angled cuts along the walls. That’s nearly 20% more material than the base measurement suggests. Miss that calculation, and you’re making an emergency trip to the showroom and hoping the same tile is still available.

Step-by-Step: How to Measure Your Kitchen Floor for Tile Installation
Step 1: Clear the Space
Before measuring, move any rugs, mats, and portable furniture from the floor. You need a clear view of the entire floor area, including the spaces under the toe kicks of your lower cabinets.
Step 2: Identify Your Kitchen’s Shape
Most kitchens fall into one of these layouts:
- Rectangular/square: Measure length x width
- L-shaped: Divide into two rectangles, measure each separately
- U-shaped: Divide into three rectangles
- Galley with obstacles: Measure the full rectangle, then subtract any fixed island or permanent base that won’t receive tile
If you’re not sure how to break your kitchen into measurable sections, our tile installation team can walk you through it during a free in-home measure visit.
Step 3: Measure Each Section
Use a metal measuring tape; cloth tapes stretch and give inaccurate readings. Measure in feet, recording length and width to the nearest inch. Convert inches to decimal feet for the math (e.g., 10’6″ = 10.5′).
For each rectangular section: Length (ft) x Width (ft) = Square Footage
Add all section totals together for your base square footage.
Step 4: Add the Waste Factor
This is where measuring your kitchen floor for tile installation gets more nuanced. Your base square footage is never your order quantity. You always add a percentage for waste — tiles cut at walls, broken tiles during installation, and reserve stock for future repairs.
- Straight grid layout: Add 10%
- Offset/brick pattern: Add 12%
- Diagonal layout: Add 15-20%
- Older homes with out-of-square walls: Add 5%
So if your kitchen measures 85 square feet and you want a diagonal tile pattern, your order quantity should be 85 + 17 (20%) = 102 square feet.
Step 5: Account for Doorways and Transitions
Measure the width of each doorway entering your kitchen. Tile Installation typically extends to the center of a doorway threshold, where a transition strip meets the adjacent flooring. Add these transition areas, usually 1-2 square feet per doorway, to your total.
Step 6: Subtract Fixed Cabinets (If Applicable)
If your kitchen has a permanent island that sits directly on the floor (not on legs), measure its footprint and subtract that area from your total. Note: Many designers and contractors recommend tiling under islands anyway to allow easier future reconfiguration. Ask our team what approach makes the most sense for your specific layout.
Tile Size and How It Affects Your Measurement Calculations
When you’re planning to measure your kitchen floor for tile installation, the tile size you choose directly affects how your measurements translate into an order quantity.
Larger tiles (18×18 inches and up) cover more area per tile, which means fewer tiles overall. They also mean larger cuts at walls, so your waste percentage stays similar. Large-format tiles in small kitchens can look stunning — fewer grout lines give the floor a cleaner, more open look.
Smaller tiles (4×4 or 6×6 inches) require more tiles and more grout joints. In a small kitchen tile flooring project, this means more precise cutting and longer installation time. However, small tiles in mosaic or hexagonal formats create beautiful focal-point floors without overwhelming a compact space.
12×24 rectangle tiles are currently popular for kitchen floors in Asheville and Hendersonville because they elongate the visual field, making a small kitchen feel larger. Offset brick patterns with 12×24 tiles work beautifully in galley kitchens.

Common Measuring Mistakes to Avoid
Knowing how to measure your kitchen floor for tile installation also means knowing what not to do.
Measuring only once. Always measure twice and confirm your numbers. A single incorrect measurement can cascade into ordering the wrong quantity.
Forgetting the waste factor. This is the most common error. Base square footage is never your order quantity.
Ignoring out-of-square walls. In older WNC homes — particularly Craftsman bungalows and mountain cabins — walls are rarely perfectly square. When you’re tiling against an out-of-square wall, the cuts are larger and less uniform, which increases waste. Add 5% extra for older homes.
Not measuring under appliances. Refrigerators, dishwashers, and stoves are movable. Tile should run under them so that future appliance replacements don’t expose the raw subfloor. Include these areas in your measurement.
Assuming tile size from photos. A tile Installation that looks like a 12×12 in a showroom photo might be a 16×16. Always confirm the actual tile dimensions before measuring, as they affect your layout calculations.
Professional Measurement vs. DIY Measurement
There’s nothing wrong with measuring your own kitchen floor. For a simple rectangular kitchen, it’s genuinely straightforward. But for small kitchens with irregular shapes, permanent obstacles, or older WNC construction with out-of-square walls, a professional measurement saves money and aggravation.
Leicester Flooring offers free in-home measurements for homeowners throughout Asheville, Hendersonville, Buncombe County, and Henderson County. Our installers measure the way they install — accounting for your specific tile size, layout direction, doorway transitions, subfloor condition, and waste factor. The measurement visit also gives you a chance to ask questions about subfloor prep and installation timeline.
If you’re comparing ceramic and vinyl tile options, our team can also walk you through how each material affects your measurements and layout planning. Learn more about vinyl flooring options as a comparison.
Measurement for Different Tile Layouts in Small Kitchens
One of the most practical aspects of learning how to measure your kitchen floor for tile installation is understanding how layout direction affects your calculations.
Straight grid: Tiles run parallel to the walls: simplest layout, lowest waste, easiest to measure.
Offset/brick pattern: Each row of tiles is offset by half a tile length from the row above. Popular with 12×24 tiles. Adds about 10-12% waste.
Diagonal/45-degree: Tiles are rotated 45 degrees to the walls. This is the layout that most dramatically expands the visual size of a small kitchen — but it demands the highest waste factor (15-20%) and the most precise measurement. Every edge tile against the wall requires a diagonal cut.
Herringbone: Two tiles form a V-shape. Common with subway-style rectangular tiles. Adds 15-20% waste and requires careful layout planning to center the pattern symmetrically in the kitchen.

Frequently Asked Questions
How do I calculate square footage for an L-shaped kitchen?
Divide the L-shape into two separate rectangles. Measure each rectangle’s length and width, calculate each section’s square footage, then add the two totals together. Don’t forget to add your waste factor (10-15%) to the combined total.
Should I include the area under my kitchen island when measuring my tile?
Yes, in most cases. Even if your island currently sits on a tile, placing a permanent island under the tile protects your subfloor and allows future layout flexibility. Include the island’s footprint in your gross measurement unless your contractor specifically advises otherwise.
What waste percentage should I use for a small kitchen with diagonal tiles?
Use 15-20% for diagonal tile layouts. For kitchens with out-of-square walls — common in older Asheville and Hendersonville homes — add 5%. So a 75-square-foot kitchen with diagonal tile in an older home should target 90-95 square feet of material.
