Countertops are priced by the square foot, so an accurate measurement is the first step to a realistic quote. The calculator above does the math as you draw, but here is how it works if you want to check it by hand.
Run 1: 120″ × 25.5″ = 3,060 sq in
Run 2: measure it from the wall to the edge of run 1 so the corner isn’t counted twice: (96″ − 25.5″) × 25.5″ = 1,798 sq in
Island: 72″ × 36″ = 2,592 sq in
Countertops: 3,060 + 1,798 + 2,592 = 7,450 sq in ÷ 144 = 51.7 sq ft
4″ backsplash on both walls: (120″ + 96″) × 4″ = 864 sq in ÷ 144 = 6 sq ft
Fabricators cut your countertops from full slabs, so the number of slabs your layout needs also affects the price. That’s why a final quote is confirmed when we template your space.
Measure each section’s length and depth in inches, multiply them, divide by 144, and add the sections together. The calculator above does this automatically as you draw your layout.
Standard kitchen countertops are about 25½ inches deep, which covers 24-inch base cabinets with a small overhang at the front. Bathroom vanity tops are usually shallower.
Measure it separately. A standard 4-inch backsplash is usually cut from the same slab, so it adds to the material you need. Full-height backsplashes add much more.
Split it into rectangles. Measure one run at full length, then measure the next run from the wall to the edge of the first one so the corner square isn’t counted twice.
No. The countertop is cut from a full piece of stone, so square footage is measured before cutouts. Cutouts are usually priced separately.
