Granite Countertop Square Foot Calculator

Plan your granite countertop project with confidence. Break your countertop into rectangles, measure each one, and get an instant square footage estimate. No complex calculations required.

How to Measure Your Granite Countertops

Divide your countertop into rectangular sections. Measure the length and width of each rectangle and enter the values into the calculator. Remember:

  • Cooktop and sink cutouts do not affect square footage.
  • Include all islands, peninsulas, and L-shaped corners.
  • Measure carefully to reduce waste and avoid ordering extra material.

Why Accurate Granite Measurements Matter

  • Plan your project efficiently and reduce material waste.
  • Get a realistic cost estimate before contacting a fabricator.
  • Ensure your slabs cover the full area with minimal seams.
  • Prevent surprises during installation that could increase costs.

Granite-Specific Tips

  • Granite is natural stone; each slab is unique, and yield varies with veining.
  • Edge profiles and corner details may slightly increase square footage.
  • Larger islands or unusual layouts may require multiple slabs—our calculator accounts for this.
  • Consider ordering a little extra for matching patterns or future repairs.
