How to Measure Your Countertops
Break your countertop area into separate rectangles. Measure the length and width of each rectangle — islands, peninsulas, and L-shaped sections included. Enter your measurements into the calculator above. Cutouts for sinks or cooktops do not affect square footage.
Why Accurate Measurements Matter
- Estimate material needs and reduce waste.
- Get realistic cost estimates for granite, quartz, marble, and quartzite.
- Plan for overhangs and islands accurately.
- Avoid unexpected costs during installation.
