Countertop Thickness and Seams Explained

Standard thicknesses, mitered edges, slab sizes and seam placement explained in plain language.

Slabs come in common thicknesses, usually about 2 centimeters or 3 centimeters for stone and quartz, with thinner and thicker options in porcelain and sintered stone. Thickness affects the look, the weight, the strength and the cost, and a mitered or laminated edge can make a thinner slab look thick. Slabs also come in limited sizes, which is why many kitchens have a seam where two pieces meet.

A good seam is planned and almost invisible. It sits over solid cabinet support, away from sinks and cooktops, and it lines up the pattern as well as the material allows. A poor seam is wide, uneven or stained. We discuss thickness, edge buildup and seam placement before cutting, and we show you the layout. In Nashville, many kitchens use 3 centimeter stone and one or two seams. We explain the options for your layout.

The details

What defines Thickness and Seams

Standard thickness

About 2 or 3 centimeters is common.

Built-up edges

Questions

Thickness and Seams FAQ

Is thicker stone better?

It looks more substantial and handles overhangs better, but it weighs and costs more.

Where do seams usually go?

Often at corners or near the sink, away from direct stress and fixtures.

Can seams be hidden?

Seams show as a thin line. Patterned stone hides them better than plain colors.
