What Is a Countertop Overhang?
Countertop overhang varies against walls, next to appliances, and for bars or countertop seating.
With countertop seating, an even greater overhang distance is needed because the users legs are bent while seated.

Be sure to look at the wall side of the straight item, not the room side.
This figure is your countertop overhang distance.
70% of the overhang should be supported by the cabinets underneath it.
In cases where you require more than the 30% overhang rule (i.e.
kitchen islands, bar countertops, and peninsula countertops), various support options can help.
Brackets
A countertop measuring 6 inches or longer should have brackets to support it.
These simply install on the underside of the countertop.
you could purchase countertop overhang kits or bracket kits online.
Posts
Posts are the only support option for countertop overhangs that would exceed more than 24 inches.
Posts can lessen the amount of leg room available for seating, however, so keep this in mind.
Corbels
Corbels can support a countertop overhang of up to 24 inches.
Corbels stick out from the wall.
Forkitchen island seating, the minimum countertop overhang required would be 36 inches.
In this case, you will need extra support to make this possible.
