Calacatta Linear Quartz Countertops GQ-T308 for Wholesale

A standard jumbo quartz slab typically measures around 108 inches by 54 inches, which equates to about 40.5 square feet. That’s roughly twice the size of a regular slab, making it ideal for large kitchens or commercial spaces where you want to minimize seams. But here’s the catch—actual dimensions can vary slightly depending on the manufacturer. Some brands might go a bit larger or smaller, so always confirm the exact specs before ordering. Also, keep in mind that while jumbo slabs reduce seams, they’re heavier and trickier to handle, which means you need a fabricator experienced with big pieces. If you’re planning a long run, like an island or waterfall edge, jumbo slabs can be a game-changer, but only if your space and layout allow it.

The largest quartz slab you can typically buy is a super jumbo slab, which can measure up to 136 inches by 77 inches—roughly 85 to 90 square feet. Some manufacturers, like Grand Quartz Tech, offer even custom sizes for commercial projects. These are engineered for projects where seam minimization and visual continuity matter most: large open-plan kitchens, hospitality spaces, and institutional builds. Unlike standard or jumbo slabs, super jumbo sizes require specialized handling equipment and experienced fabricators familiar with oversized material logistics. Weight, structural support, and cabinet layout all need careful evaluation before specifying. GQ—our factory in Chonburi, Thailand, with 37 years of stone experience—produces super jumbo slabs on dedicated lines, including low-silica and full-body printed options, all SGS and NSF certified. Availability depends on color, finish, and production scheduling, and lead times typically run 20–30 days. Most fabricators will tell you: if your project calls for this scale, confirm slab dimensions early and verify installation readiness—not just aesthetics.

The difference between jumbo and super jumbo quartz slabs comes down to size, application, and logistics. A jumbo slab is typically around 126 inches by 63 inches (about 40.5 sq ft), which is roughly double the size of a standard slab. It’s great for reducing seams in large kitchens or islands. A super jumbo slab, on the other hand, is much bigger—usually 136 inches by 77 inches or larger (85–90 sq ft). That extra size means fewer seams and a more continuous, seamless appearance, especially useful in commercial or luxury residential projects. But with size comes complexity: super jumbo slabs are heavier, harder to transport, and require specialized equipment to cut and install. They’re also more expensive and less common. So while both are designed to minimize seams, super jumbo is for big, bold projects where every detail matters—and where you’re willing to pay extra for the look and logistics.
