The maximum overhang for a quartz countertop with no additional support is no more than 1/3 of its depth and can not exceed 15” total. Overhangs greater than 15” require the installation of corbels. The corbels must be designed to support the weight of the quartz countertop and be mounted to studs.
The maximum overhang is no more than 1/3 of the total dimension of the countertop – not to exceed 15”. Overhang greater than 15” requires corbels or flush mounted steel supports. Supports must be designed to bear the weight of the countertop and be mounted to studs or equivalent load bearing structure.
An island overhang of over 12 inches will require proper reinforcement to securely brace the supplemental countertop material. Thankfully, there are a number of decorative and stylish manners to provide this additional support. Countertop overhangs that extend past 12 inches can be supported with columns.
You should use a countertop bracket that extends within four inches of the countertop edge. This prevents too much pressure and weight on the countertop without proper backing. Fasten these brackets with fasteners to keep them securely in place.
Different countertop materials have different requirements. Solid Surface countertops can overhang 6 inches without additional support (e.g. plywood decking). 3 cm Quartz (engineered stone) can handle a 14 inch overhangs and 3 cm Granite overhangs should not exceed a 10 inch overhang without additional support.
1- How much overhang do you have
Most granite fabricators will recommend support brackets on overhangs over 12″ however, solely based on the overhang amount. Final determination on bracket requirements and spacing should be recommended by your fabricator based on the following factors.
Quartz countertops are heavy, and not all cabinetry is strong enough to hold it. In addition, you may have unsupported areas, such as desks or overhangs that may need some support. If your cabinets cannot hold the weight of the quartz, plywood or backer board may be used beneath the countertop to help.

Plywood is necessary when you need it to absorb pressure and prevent cracks. That will directly depend on the thickness of the quartz.
Quartz can be more expensive than other countertops but is generally cheaper than natural stone and other luxury options. It does require professional installation and can discolor when exposed to high temperatures and extensive heat for long periods.
Quartz is made up of mostly quartz mixed with resin. The resin in the quartz is highly affected by heat, and this is why placing a hot pan on quartz is so strongly discouraged. If you were to put such high heat on quartz, the resin is very likely to burn and the countertop's coloration would be significantly impacted.
While quartz countertops can be placed directly on top of cabinets, their weight shouldn't be underestimated. Take a look at your countertop design and look for areas that have the least amount of cabinet support.
Corbels: These are functional supports that jut from a wall. Corbels can support quartz countertop overhangs from a 15 inch to a 24-inch overhang. Whether you opt for a decorative or basic functional corbel, ensure they fully support the weight of the quartz countertop overhang.
