Countertop calculator
Choose your counter shape, enter the run lengths, and add an island or peninsula. You'll get square footage, finished edge length, a real slab layout with seams, and installed cost for every material, including cutouts and edge profile.

Slab layout
4 pieces · about 2 seams
Tip: with jumbo slabs (130 × 65 in) this layout needs 2 slabs instead of 3, often with fewer seams. Ask your fabricator.
Corners count once. L and U shapes need a seam at each corner unless the fabricator cuts an L from one slab.

How the calculator works
Runs are split into countertop pieces with corners counted once. Pieces longer than the chosen slab get a seam. The pieces are then packed onto slabs of the material you pick (for example 120 × 55 in for standard quartz) to estimate how many slabs a fabricator will need. Real fabricators also consider vein matching and defects, so treat the count as a minimum.
Frequently asked questions
- How do I measure for countertops?
- Measure each run along the wall from end to end. In an L or U, measure every run to the outside corner; the calculator removes the overlap at corners automatically. Standard depth is 25–25.5 in including the overhang.
- How many slabs do I need?
- It depends on the slab size and how the pieces fit. Standard quartz slabs are about 120 × 55 in and jumbo slabs about 130 × 65 in. The slab layout above packs your actual pieces onto slabs, so the count reflects seams and offcuts.
- How much does a countertop cutout cost?
- Sink and cooktop cutouts typically add $150–$350 each, depending on the material and whether the sink is undermount.
- What's the most durable countertop?
- Quartzite, granite, and porcelain resist heat and scratches best. Quartz is the most stain-resistant and needs no sealing, but it should be protected from very hot pans.
- Is quartz or granite cheaper?
- They overlap: both commonly run about $55–$120 per sq ft installed. Entry-level granite can be cheaper; premium quartz designs can cost more.
