Countertop Calculator
Calculate how much countertop material you need.
Enter kitchen dimensions and edge type to get square footage or square meters.
Countertop area is calculated by multiplying the total counter length by the depth (front to back).
Formula:
Total Area = Sum of (each section length × depth)
Standard countertop depth: 25.5 inches (65 cm) including a 1.5-inch overhang.
Countertop material costs (per sq ft):
- Laminate: $10–40
- Butcher block: $40–100
- Granite: $50–200
- Quartz: $50–150
- Marble: $75–250
- Soapstone: $70–120
Add extra for:
- Backsplash (if same material): 4 inches (10 cm) high × counter length
- Edge profiles: No extra material needed, but add $5–30/linear foot for fabrication
- Waste/cuts: Add 10–15% for seams, cutouts (sink, cooktop), and waste
Tip: Measure each straight section separately, then add them together. Don’t forget island countertops.
