Corner overlap is subtracted once. Slabs use a typical 120 × 55 in size at 80% yield. Your fabricator templates the job and sets the final count.

Get square footage from your layout and an early slab count, so you can compare stone before you pay for a template.

How it works

Sums each run × depth, subtracting corner overlap, and adds any stone backsplash. Slabs assume 120 × 55 in at 80% yield.

Before you order

  • Have the fabricator template after base cabinets are installed.
  • Plan seams away from the sink and cooktop where possible.
  • Check that the delivery route can handle a full slab.

Common questions

How deep is a standard counter?

Base cabinets are typically about 24 in deep, and a finished top with overhang runs about 25.5 in.

How many slabs will I need?

A typical slab has about 45 sq ft, and layout, seams and vein matching often bring usable yield near 80%. Your fabricator decides.
