Countertop Size and Slab Planner

Enter your run lengths and depths to see square footage, how many slabs a layout may need and where seams often fall.

These tools give planning-level estimates from typical values and the details you enter. They are not quotes or engineering or safety advice, and results depend on your actual cabinets, their condition, products and local rules. Only a visit can confirm what a project needs, and we give you a written estimate before anything is ordered.

How it works

Four quick steps.

  1. 01

    Pick a starting point

    Each preset loads typical run lengths for a layout.

  2. 02

    Enter your measurements

    Run lengths, depth, island size and backsplash height in inches.

  3. 03

    Choose a slab size

    Standard or jumbo slabs.

  4. 04

    Read the estimate

    See square feet, the number of slabs to plan for and where seams may fall.

Tips

  • Measure each run along the front edge of the cabinets.
  • Remember to include the island and any peninsula.
  • We template your actual cabinets before anything is cut.
