Granite Countertop Square Footage Calculator

Enter your runs, island, backsplash and waste to see square feet to order, slabs, likely seams and a planning range.

These tools give planning-level estimates from typical values and the details you enter. They are not quotes, designs or engineering, and results depend on your actual stone, cabinets, the condition of the home, availability and local rules. Only a home visit can confirm what a project needs, and we give you an itemized written estimate before any work begins.

How it works

Four quick steps.

  1. 01

    Measure the runs

    Enter the length of each run of counter and its depth.

  2. 02

    Add the island and splash

    Include the island size and any backsplash length and height.

  3. 03

    Set the waste

    More cuts, seams and pattern matching mean more waste.

  4. 04

    Read the result

    See square feet to order, slabs, likely seams and a planning range.

Tips

  • Measure along the wall, corner to corner, and add overhangs.
  • Standard counter depth is about twenty-five and a half inches.
  • Your installer confirms the slab count after templating.
Questions

About this tool.

How accurate is the slab count?

It is an estimate. Layout, pattern and defects change how a slab yields, so your fabricator confirms it.

Should I include the backsplash?

Yes, if it will be the same stone, so the slab count covers it.

Why add waste?

Cutouts, edges, seams and pattern matching all use material.
