Quartz is one of the best materials for those looking to create a countertop overhang. The strength and durability ensure it can support up to a 14-inch overhang without extra support. However, 70% of your
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.
The typical measurement for island overhang is up to 12 inches, which should provide sufficient space for people to fit their knees comfortably underneath.
A typical overhang for a comfortable seating area should be around 25-30cm (10-12”), this should leave enough knee room and adequate space between the countertop edge and the person seated. Therefore, as the depth of the overhang increases, so does the comfort and usability of the bar.
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.
If your island has seating, the counter should overhang at least 15 inches. An island with a taller height for bar stool seating should be 42 inches high and the overhang should be at least 12 inches.
Standard countertop overhang is 1 ½ inches.
Keep in mind that this is 1 ½ inches over the front edge of the base cabinet. While some countertops may have different overhang measurements, this is the number that is seen as standard for homes.
Homes in milder areas have typical overhangs of 12-18 inches, while 18-24 inches if more common in wet or extreme climates.
A standard countertop usually has an overhang of 1½ inches. Although some countertops may have a longer or shorter overhang, this number is generally the standard length for an overhang in homes.
Quartz Countertop Support Options
Corbels. Corbels are support fixtures that protrude from your primary support. They can support up to 24 inches of overhang provided that they are mounted on studs and that they've installed three feet apart from each other, no more, no less. Substrates and Posts.
You might want to rethink standing or sitting on your quartz countertop. While a quartz countertop is strong and durable, do not use it as a sitting or standing tool.
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.
The maximum allowable overhang is no more than 1/3 of the depth of the countertop and not to exceed 15” total. 2. Overhangs greater than 15” require the installation of corbels. Corbels must be designed to support the weight of the countertop and be mounted to studs or an equivalent load bearing structure.
Things to consider when planning an island or breakfast bar
The usual maximum for an unsupported overhang in granite or quartz is between 250mm-300mm depending on the thickness. Larger overhangs will require extra support by way of breakfast bar leg or some sort of downstand/end support panel or brace.
Almost certainly, yes. Generally speaking, unless your kitchen units are very old, it is highly unlikely that they will be too weak to handle the weight of any solid stone worktops, including quartz.
Pounds Per Square Foot
The load for normal shingled or wooden roofs follows the same code. With that in mind, the code typically starts out at 20 pounds per square foot. Residential roofs can hold a minimum of around 20 pounds per square foot then top out at 100 pounds per square foot.
Ideal Overhang Length
Once the drip edge is installed, the shingles should extend ½ inch to ¾ inch past the drip edge. If the shingles are allowed to extend too far, then they can be caught by the wind and damaged. If they do not extend far enough, driving rain can get under them and damage the roof deck.
The underside of this overhang, when given a finished appearance, is known as the soffit, which means “something fixed underneath”. The soffit is basically, any finishing material, such as wood or fiber cement, that is installed to cover the underside of your roof overhang.
You can get away with no overhang to just sit near the counter (sitting sideways) but it's standard to use 12 to 15" to be comfortable.
Like granite, quartz is sold in slabs; however, all slabs max out at a certain length. The most common maximum slab length for both granite and quartz is 125” L x 65” W. This means if your lower cabinets are longer than 125” in length that your countertops will have to be seamed.
The minimum countertop overhang for seating is 10″, but we recommend at least 12″ for ideal comfort. You could choose a tiered countertop, which will have multiple heights for seating.
In general, the recommended countertop overhang is between 1 and 1.5 inches. 'The standard overhang measurement is based on the fact that most people find this distance be the perfect place to rest their forearms while food prep is taking place,' notes Chris Alexakis, founder of CabinetSelect.
The standard countertop overhang is mere inches long and averages from 1 to 1½ inches long. However, if you want to extend your overhang to accommodate seating, you'll need the measurement to account for legroom.
