How to Measure Countertops Accurately

Getting accurate measurements is the first step in planning your kitchen countertops. Proper measurements help reduce waste, avoid surprises, and give you a precise estimate for granite, quartz, marble, or quartzite countertops.

Step-by-Step Guide to Measuring Countertops

  1. Measure the length and width of each countertop section from wall to wall.
  2. Include islands, peninsulas, and L-shaped corners as separate sections.
  3. Note overhangs and edge profiles that may add material.
  4. Mark cutouts for sinks, cooktops, and appliances.
  5. Double-check all measurements for accuracy.

Tips for Accurate Measurement

  • Use a long tape measure for large sections.
  • Sketch your layout on graph paper or use a smartphone app.
  • Measure multiple times to ensure accuracy.
  • If unsure, your local fabricator can verify measurements before fabrication.
