Quartz Slab Sizes, Thickness and Weight: A Buyer’s Guide
Standard and jumbo slab sizes, 2 cm and 3 cm thickness, and how much a quartz slab weighs, with LIVEN’s four slab sizes in millimeters and inches.
Standard, jumbo and larger formats
There is no single standard size for quartz slabs, but most fall into two formats. Standard slabs are around 3000 × 1400 mm (about 118 × 55 in). Jumbo slabs are around 3200 × 1600 mm (126 × 63 in) and are now the usual choice for kitchen countertops, because a larger slab covers an island or an L-shaped run with fewer seams. Some manufacturers also make larger formats, often called super jumbo.
| Size (mm) | Size (in) | Area per slab | Approx. weight at 20 mm |
|---|---|---|---|
| 3000 × 1400 | 118.1 × 55.1 | 4.20 m² (45.2 sq ft) | 220 kg (490 lb) |
| 3200 × 1600 | 126.0 × 63.0 | 5.12 m² (55.1 sq ft) | 270 kg (595 lb) |
| 3200 × 1800 | 126.0 × 70.9 | 5.76 m² (62.0 sq ft) | 300 kg (670 lb) |
| 3500 × 2000 | 137.8 × 78.7 | 7.00 m² (75.3 sq ft) | 370 kg (810 lb) |
Weights are estimates scaled from about 270 kg for a 3200 × 1600 × 20 mm slab. Confirm the size you need for each color code in your inquiry.
Choosing a slab size
Start from the largest single piece in the project, usually the island top or the longest countertop run, and add the overhang and edge details. If that piece fits on one slab, it needs no seam. A jumbo slab of 3200 × 1600 mm, for example, can take an island top of up to about 3 m by 1.5 m in one piece, depending on the edge and fabrication allowances.
Larger formats such as 3500 × 2000 mm suit wide islands, feature walls, and waterfall islands where the top and the ends are cut from one slab so the veining continues around the corners. For vanity tops, backsplashes and other small pieces, a standard slab can leave less waste. Lay out every piece on the slab dimensions before you order, allowing for sink and cooktop cut-outs and for vein matching.
Thickness: 2 cm, 3 cm and thinner slabs
Thickness depends on the application and the local market. In North America, 2 cm (about 3/4 in) and 3 cm (about 1 1/4 in) are the usual countertop thicknesses. 3 cm is widely used for kitchen countertops set directly on the cabinets; 2 cm is common for vanity tops and backsplashes, and for countertops installed on a supporting subtop or with a built-up edge. Thinner slabs are lighter, which suits wall cladding, shower walls and furniture.
| Thickness | Approx. weight | Common uses |
|---|---|---|
| 12 mm (0.47 in) | 32 kg/m² (6.5 lb/ft²) | Wall cladding, backsplashes, shower walls, furniture |
| 15 mm (0.59 in) | 40 kg/m² (8.1 lb/ft²) | Wall cladding, furniture, tabletops |
| 18 mm (0.71 in) | 48 kg/m² (9.7 lb/ft²) | Vanity tops, countertops on a subtop |
| 20 mm (2 cm, about 3/4 in) | 53 kg/m² (10.8 lb/ft²) | Kitchen countertops, islands, vanity tops, commercial flooring |
LIVEN quartz slabs are made in 12, 15, 18 and 20 mm. If your market needs 3 cm slabs, ask LIVEN’s sales team about availability.
How much does a quartz slab weigh?
Weight scales with area and thickness. A LIVEN 3200 × 1600 mm slab at 2 cm weighs about 270 kg (595 lb), about 53 kg per square meter (about 11 lb per sq ft). The tables above scale this figure to the other sizes and thicknesses. Actual weight varies slightly with the color and the batch, and the packing list states the weight of each shipment.
Weight matters at every step: container loading, handling in the warehouse, and installation. Slabs travel and are stored upright on A-frames or racks, are lifted with slab clamps, and the cabinets and supports under a countertop must be sized for the load.
