Square feet and slab count
Slab calculator
Add your counters, island, vanity or walls. You’ll see the square footage, the finished edge, how many slabs you need, and every cut laid out on the slab you choose.
01
What are you covering?
Tap to add the usual sizes, then change them below. Add as many as you need.
02
Sizes and edges
Length runs left to right. Width is front to back for a counter, or the height of a wall. For each edge, choose whether it sits against a wall, shows as a finished edge, or drops to the floor as a waterfall.
03
Your cuts on the slab
Pick a slab to see every cut laid out on it. The faded areas are offcuts.
Drag a cut to place its pattern where you want it. On a phone, tap Move cuts first. Turn swaps its direction on the slab.
A planning guide, not a cut list. Each slab is 5′ 3″ × 10′ 6″ (1600 × 3200 mm) and 12 mm thick. We keep ½ in off every slab edge and allow ¼ in for each saw cut. Your fabricator confirms the final layout.
