Overhang. If you plan to include seating at the island, provide a comfortable overhang for legroom. A typical overhang for seating is around 12 to 18 inches (30 to 46 cm) from the edge of the countertop to the outer edge of the seating area.
Recommended Island Overhang Lengths
For standard barstools with a seat height of 30 inches, a 12 to 15-inch overhang is recommended. For counter-height barstools with a seat height of 24 inches, a 15 to 18-inch overhang is ideal.
How much overhang do you need for a kitchen island? Most islands require a slight countertop overhang to ensure diners have plenty of legroom when seated. 12 inches is the ideal rough size for an overhang, but the clearance around the island is your first priority.
Generally speaking, a countertop overhang of 12-18” is a good place to start. It's worth noting that 12” likely won't allow your bar stools to tuck in all the way.
The standard island overhang countertop is 12 inches. However, you can have a longer overhang provided you add support that extends half the distance of the overhang. The 12 inches island overhang countertop is generally utilized for a bar seating area around the island.

40" Minimum Clearance Between all Counters, Base Cabinets, Appliances, and Walls In more elaborate kitchens where an island is planned, the 40-inch clearance must be maintained between the face of the island and all opposing features.
The most common countertop overhang measurement seen in homes today is one and a half inches. This is considered the ideal measurement because it creates the perfect place for people to rest their forearms while preparing food.
According to the National Kitchen & Bath Association guidelines, having at least 36 inches of clearance space around the kitchen island allows for ease of movement and access to kitchen cabinets and appliances.
Large island overhangs up to 18” can be supported with large corbels, a welded steel frame of 1”x2” rectangular steel tubing with a wall thickness of ⅛”, or a series of COUNTERBalance™ IslandBrackets™.
So, what's replacing the kitchen island? One popular trend is the rise of multifunctional dining tables. These tables can serve as both a dining area and additional prep space. Imagine a beautifully crafted table that can accommodate family dinners or function as a workspace for meal prepping.
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.
4-6 ft (48″—72″): This size range balances workspace and storage while allowing enough room for comfortable movement around the island. Over 8ft (96″): This is best for large kitchens that need extensive workspace, storage, and even a dedicated seating area.
1- How much overhang do you have
Amount of overhang you have is the most important factor to consider in deciding whether you need support brackets. Most granite fabricators will recommend support brackets on overhangs over 12″ however, solely based on the overhang amount.
The standard size for an island bench is 900mm deep, this allows for 600mm deep cabinetry and a 300mm over hang for seating. If the overhang is more than 300mm it does require additional support! Ideally, we would also allow a 600mm width per person for maximum comfort.
For the eaves, which are the lower edges of the roof, the overhang should be between 12 and 18 inches. This means the roof should stick out 1 to 1.5 feet past the walls. For the rakes, which are the sloped edges of the roof at the gable ends, the overhang should be about 8 inches.
The standard 12-inch overhang is ideal for most people, providing a comfortable and practical seating area. A 10-inch overhang can work if space is limited, but it might not be as comfortable. An 18-inch overhang offers plenty of legroom but requires additional support.
To comfortably fit three stools, it is recommended that the island should be at least 72 inches long, allowing for 24 inches of space per stool. This spacing ensures everyone has enough elbow room, making meals and gatherings more enjoyable.In addition to length, the width of the island is equally significant.
The typical measurement for island overhang is up to 12 inches, which should provide sufficient space for people to fit their knees comfortably underneath. If you feel you need more room, you could extend the overhang even further.
Generally, for comfortable seating, you'll need at least 12 inches of overhang. This allows enough space for legs and knees without feeling cramped. If you want to tuck your bar stools completely under the countertop, you'll need a larger overhang, typically around 15-18 inches.
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.
The general rule of printing slopes (overhangs) is that they shouldn't exceed 45-degrees. The idea behind this is to ensure each successive layer has enough support to build up on. At 45 degrees, every layer is in about 50% contact with the layer below it and hence prints well.
The industry standard is that you need at least 36 inches of space around each edge of the kitchen island. Three feet of clearance is enough so that you can comfortably walk between the island and countertops and should provide enough clearance for cabinet doors.
Receptacle outlets for islands and peninsulas are no longer able to be installed below the countertop and work surface level.
Counter height stools are around 24 to 27 inches from the floor to the seat. This height is ideal for kitchen islands or counters that are around 36 inches in height. Counter height stools have become increasingly popular in recent years due to the rise in counter height kitchen islands and the seating they bring.
