What is a jumbo slab?
A jumbo slab is a large-format stone slab commonly about 130" × 65" for quartz — roughly 58 gross square feet. Standard slabs run smaller (~119" × 56"); super jumbo runs larger (~136"–140" × 76"–82"). Always verify against the supplier bundle for the color you are buying.
Gross vs usable
Gross SF is length × width. Usable nested yield after kerf, L-shaped blanks, and grain constraints is often closer to 40–45 SF per jumbo slab. Plan slab count from yield, not gross.
From the shop floor
We publish what estimators tell us about these pages, including the parts where the software was wrong. If you run takeoff in a shop and this page got something right — or got it wrong — send it to us and it goes here with your name on it, or without it if you prefer.
