Measuring Your Natural Stone Countertops

There’s a well-known saying that should be kept top of mind during every home renovation project: “Measure twice, cut once.” In other words, it’s pretty darn important to get measurements right the first time in order to avoid costly errors! Determining how much granite you need for a countertop is no exception. Here’s how to take the right measurements to make the right call on how much granite to order.

How to Measure the Amount of Stone You Need 

First, grab your tape measure, pencil and paper, a calculator, and your thinking cap — yes, there is math involved, but don’t worry, we promise it’s not too hard! What you’re looking for is total square footage. This will tell you how much stone to order as well as give you a good idea of how much your granite countertop will cost. A drawing to-scale of your space and floor plan is helpful, but not totally necessary.


Step 1: Measure the Length and Width


Measure in inches the length from end-to-end of the surface you want covered in granite, then measure the width (typically this is around 26 inches with overhang). Pssst…here’s a little secret: don’t worry about trying to figure out how to exclude the size of your sink from the measurements. It will simply be cut out from the total slab.


Step 2: Measure Again! 


In case you didn’t hear us the first time — measure twice, cut once. Got a different number the second time? Go for a third!


Step 3: Multiply the Length by the Width


Plug your numbers into your handy-dandy calculator to multiply the length by the width. The result gives you the total area in inches. 


Step 4: Convert Your Answer into Square Feet


Now, don’t panic! You don’t have to dig out your old math textbooks or break into a sweat because of math class flashbacks. You just have to divide your total area in inches by 144.


Step 5: Measure for Your Backsplash


If you’re planning for your countertops to include a backsplash, you’ll need to calculate for that as well. The standard height of a backsplash is 4 inches, so multiply your countertop length in inches by 4 to get your backsplash measurement. Then, once again, divide that answer by 144 to convert it into square feet. 


How to Measure Non-Rectangular Countertops


While most countertops tend to be rectangular, you might have some curves or other shapes going on, but don’t fret  — you’ve got this! If you are working with non-rectangular shapes, the easiest way to take measurements is to partition the surface into boxed sections, follow the formula above to measure the length and width of each section, then add your answers together. For curved areas, measure from the flat end to the farthest point on the curve. 


How to Estimate Costs for Your Stone Project


Now that you have your measurements in hand and know the square footage you need, you can easily collect some estimates on how much your countertops are going to cost. Prices can vary depending on the type (or grade) of granite you choose, edging, color, and other factors. 


Be sure to include the cost of installation when making decisions and determining what works best for your budget. Also, know that you may not necessarily have to invest in a full slab. Sometimes, you can get lucky and find a remnant that fits your size requirements, and that can save some big bucks!
