Quartz countertops have become an increasingly popular option for kitchen and bathroom renovations in recent years. But if you’re considering quartz for your next project, you may be wondering – how big are the slabs? Here’s a detailed overview of standard quartz slab sizes to help you plan your space.
What is Quartz?
Before diving into slab sizes, it’s helpful to understand exactly what quartz countertops are. Quartz is an engineered stone made from roughly 90% ground natural quartz crystals and 10% polymer resins and pigments.
The quartz crystals make the material extremely hard and durable, while the resins bind everything together into a cohesive slab. The pigments allow quartz to come in a wide array of colors and patterns that mimic natural stone.
Compared to natural stone like granite or marble, quartz offers superior resistance to stains, scratches, heat, and cracks. And unlike more porous natural stones, quartz rarely needs to be sealed. This makes it an ideal low-maintenance option.
Standard Quartz Slab Sizes
The majority of quartz slabs on the market today come in one of these standard sizes:
Full Slabs
- 30 inches x 120 inches – This is the largest standard size available. A full slab this size provides approximately 30 square feet of coverage.
- 30 inches x 108 inches – Very similar to the size above, but 12 inches shorter. This size gives you about 27 square feet of coverage.
Half Slabs
- 30 inches x 60 inches – Half slabs are, as the name implies, half the size of a full slab. This size provides around 15 square feet.
- 30 inches x 54 inches – A slightly smaller half slab coming in at 13.5 square feet.
Third Slabs
Some manufacturers also offer third-size slabs:
- 30 inches x 40 inches – Third slabs give you 10 square feet of coverage.
- 30 inches x 36 inches – The smallest standard size at 9 square feet.
So in summary, quartz slabs range from roughly 9 to 30 square feet, with 30 x 120 inches being the maximum.
Why Standard Sizing Matters
These standard slab dimensions allow quartz manufacturers, fabricators, and installers to streamline the process. They can cut and polish slabs very efficiently without too much material waste.
Standard sizing also makes planning quartz countertops much easier on the consumer end. If you know the general size of your space, you can figure out how many slabs you’ll need without too much hassle.
That said, quartz fabricators can sometimes join together multiple slabs for larger custom projects. So don’t be constrained by thinking one slab must accommodate your entire space.
Quartz Countertop Thickness Options
Beyond just the length and width, you also have some options when it comes to slab thickness:
- 1.2 cm – The thinnest option, providing a very low profile.
- 2 cm – The most popular standard thickness, giving you a slim but sturdy profile.
- 3 cm – A thicker slab that’s more resistant to warping or cracks over time.
Thicker slabs tend to be more durable and sturdy. But thinner options work fine for most home kitchens and bathrooms.
How Many Slabs Will You Need?
Now that you know the common quartz slab sizes, you can start estimating how many you might need. Here are some pointers:
- Carefully measure the linear dimensions of your countertop spaces. Remember inside corners and irregular edges.
- Factor about 1.5 inches of overhang into your measurements for standard counter depths.
- Divide your total linear inches by 120 inches or 108 inches to estimate full slabs needed.
- Similarly, divide by 60 or 54 inches for half slabs.
- Round up to the nearest whole number to give yourself some wiggle room.
- Have your fabricator confirm your estimate to be sure.
Most standard home kitchens require 2-3 full slabs total. But precise needs vary case by case.
Added Costs Beyond the Slabs Themselves
When budgeting for quartz countertops, keep in mind you’ll need to account for more than just the slabs:
- Fabrication – Professional cutting, edging, and installing.
- Demolition and disposal – Removing old countertops.
- Backsplashes – Cutting and installing backsplash tile or panels.
- Plumbing – Disconnecting/reconnecting sinks, faucets.

Frequently Asked Questions
What are the different quartz slab sizes?
The standard sizes are 30 x 120 inches, 30 x 108 inches, 30 x 60 inches, 30 x 54 inches, 30 x 40 inches, and 30 x 36 inches. 30 x 120 inches is the largest at 30 square feet.
What is the thickest quartz countertop available?
Quartz slabs can be ordered in 1.2 cm, 2 cm, 3 cm, and sometimes up to 5 cm thickness. 3 cm is generally the thickest option for residential use.
What size quartz slab do I need for a 10 foot counter?
For a 10 foot long straight counter, you would likely need a 30 x 108 inch slab to allow for overhang. A 30 x 120 inch slab would also work.
How many slabs for a 10×10 kitchen?
A 10×10 foot kitchen would likely require 2-3 standard size slabs depending on the layout. An L-shaped kitchen may need 3+ slabs to accommodate all spaces.
How do you calculate how many quartz slabs you need?
Measure total linear inches of counter space needed, factoring 1.5 inch overhangs. Divide by slab widths of 120, 108, 60, or 54. Round up to estimate slabs needed.
Can quartz countertops be cut to size?
Yes, quartz fabricators will cut and polish slabs to precisely fit your countertop layout. They can even join multiple pieces for custom looks.
