Countertops
Countertop and Slab Calculator
Estimate how many slabs your countertops need from the linear run, counter depth, and backsplash, with seams and waste.
Countertop / Slab Calculator
Counter run to square footage to slabs, including backsplash, seams, and waste.
— slabs
Assumes a typical usable yield per slab; final yield is confirmed at template. Estimate only. Confirm with our team before ordering.
How it works
Three steps to your estimate
01
Measure your run
Add up the linear feet of every counter section, including islands.
02
Add depth and backsplash
Standard counters run about 25 inches deep; add your backsplash height.
03
Read your slabs
The calculator converts the run into square footage and the number of slabs, with seams and waste.
Common Questions
Countertop and Slab Calculator FAQ
How many slabs do I need?+
Enter your total linear run, counter depth, backsplash, and a waste factor, and the calculator estimates the slabs you need from a typical usable yield per slab. Final yield is confirmed at template.
How much waste should I plan for?+
Plan about 10 percent waste for a standard layout and 15 percent for L-shapes or complex runs with more seams. Set the waste factor in the calculator to match your layout.
How is usable yield decided?+
A typical slab yields a set amount of usable square footage after edges and cutouts. Final yield is confirmed at template for your specific project.
Do you template and fabricate?+
Yes, we offer template, fabrication, and install options for your project. Talk to our team and we will walk you through the right path.
