For calculating area first of all you need to measure the length and depth of the kitchen countertop using an inch tape in inches.
For example, we take your kitchen length as 110 inches and depth as 30 inches.
Important Considerations when Measuring for Granite Countertops
Choosing granite as the surface for your countertops is an investment. For the most part, you are paying a premium price for this material. It will pay itself in the long run though since granite adds value to your kitchen and the property as a whole. There are a few things to consider when making measurements on your granite countertops.
First, granite is made of natural stone. A very hard and dense material. Once cut, there is no going back. Every decision made on granite is final.
Next, overhang. An overhang is a part of the countertop’s edge that exceeds the base. This allows for a wider countertop area without having to modify the base. It also adds aesthetic value. Too much overhang produces larger areas of the stone that is hanging unsupported. These areas cannot bear too much weight and are prone to chipping and breaking.
Lastly, when measuring for countertop surfaces always keep in mind the entire floor plan. Where you put your fridge or gas range may limit the amount of counter space.
The Average Countertop Square Footage
The average measurement for a kitchen countertop is 30 square feet. However, the variation between kitchen designs is vast. There are kitchens with much smaller or significantly larger countertop measurements. The right size for your kitchen will depend on the floorplan and counterspace you want in your kitchen design.
Depth and Length
The standard depth for cabinets and countertops is about 25 inches. Therefore, the 30 sq-ft average assumes a total countertop length of about 14 feet. However, you can change the profile and square footage of your countertops by choosing to make them (and your cabinets) narrower for a slimmer countertop or shorten your counter for a little more exposed wall in the kitchen.
Islands and Countertop Sections
Measure every section of your kitchen that will be counter-topped. If you have counter sections separated by the fridge, stove, and doors, be sure to include their square footage in your measurements. Measure the island as well, along with any island second-level as some islands have a countertop and bar surface both in beautiful slab.
What Size Slab Do I Need for My Countertops?
The average size of a countertop-ready stone slab is about 115″ by 70″, or 60-70 square feet each – give or take according to the slab, quarry, and shipment. But how much slab do you need to fulfill your countertop needs? Should you buy one or two? Can you buy a half-slab or just as much as you need for the countertops? The question depends on how you want to choose your custom countertop cut, grain, and if you want first pick of the remnant stone.
Countertop Measurements and Your Stone Slab
Many homeowners choose to buy an entire slab to cut their countertops and additional stone surfaces. However, you can also choose to commission your specific countertops and leave the remnant and half-slab concerns to your stone fabricators.
If you want to optimize your slab use, talk to us about how your countertops will fit into the slab cut and how much margin is needed between each cut piece on the slab. Then we’ll talk about the remnants created and how to make the most of them.
Artistic Cuts Along the Grain
As stone fabricators, we are passionate about beautifully cut countertops. Sometimes, that means finding the slab with the perfect grain for your kitchen. We can line up the cutout of your countertops on the slab so that the grain sweeps beautifully over your surface and each seam is nearly invisible. This is an artistic cut, though can often leave larger remnants from the unselected sections of the slab. A creative stone fabricator can often help you build a beautiful multi-surface counter with careful and artistic cuts through each unique grain.
Ways to Use Your Slab Remnants
If you bought a whole slab (or more) and have stone remnants, make use of them! There are some wonderful smaller pieces you can make with granite or marble remnants, and some remnants aren’t that small. Adorn smaller countertops, make a stone-topped table, or cap your mantlepiece. You can also have small items like platters and bowls crafted, use them for outdoor paving, or even have a chess boar etched into a remnant.
How to Measure for Granite Countertops
The main goal of measuring is to get the total square footage of your countertops, islands, and backsplashes. Knowing the square footage total will tell you how much stone to order and an estimate of the cost. Here are the simple steps to get you going:
Measure the length and width of the entire surface you want to be covered with granite in inches using your measuring tape.
Multiply the length by the width. This will give you the total area in inches.
Divide the total area in inches by 144 to get the area in square feet. This conversion is important because most contractors and suppliers will communicate in square feet.
For example, the length of your countertop is 100 inches. Multiply it by the width which is usually around 26” (most cabinet boxes measure at 24”. The extra inches will account for the countertop’s overhang). 100 x 26 = 2,600 in square inches. 2,600 / 144 = 18.056 Square Feet.
Measure for the backsplash. This is done by multiplying the length of the countertop by 4 inches which is the standard backsplash height. Once again divide the product by 144 to get the area in square feet.
Repeat steps 1 to 3 for all countertops, islands, and other surfaces you intend to cover with granite.

Now, you need to convert this to square feet. Divide the total inches by 144, and you will have the final number. It has to be in square feet because most suppliers and contractors use that instead of inches. For example, say your countertop measures 200 x 26 inches including the overhang. Your backsplash is 26 x 4 inches, and the island is 60 x 26 inches. This equates to 5,200 inches + 104 inches + 1,560 inches, equaling 6,864 total inches. Divide that by 144, and you will have about 48 square feet.
You will also want to measure for your kitchen sink, whether you keep the one you have or install something new. If you are getting a new one, you’ll need to know its measurements and account for it when ordering your granite slab. With existing ones, Kitchen & Bath Classics recommends using a straight edge and a ruler. Put your straightedge along the top of the sink, insert the ruler into the depth and put its bottom edge near the drain.
Measure from that bottom point to the straight edge and write down this depth measurement. Then, measure the distance from the left side to the right. Finally, measure and record the distance from the sink’s back opening to its front; this is the total length.
