Countertop area formula

Countertop area = length × depth in feet × number of equal sections. Add waste if you need a purchasing allowance.

Planning notes

Countertops are often fabricated from larger slabs or sheets, so final material ordering can depend on seams, cutouts and slab layout as well as square footage.

  • Measure each different countertop section separately when sizes vary.
  • Fabrication layouts, seams and slab sizes can affect material ordered.
