Key Planning Principles

Functionality Matrix

When planning a kitchen island, understanding the functionality matrix is crucial. Different types of kitchen islands are tailored to various needs and spaces.

Function Type Suitable Scenarios Typical Configurations
Meal Preparation Compact kitchens (<8㎡) Double sink + Built-in food processor
Social Interaction Open - plan spaces (>12㎡) Lift - up sockets + Wine cabinet + USB charging ports
Comprehensive Luxury kitchens (>20㎡) Integrated steam oven + Induction cooker + Refrigerated area

Space Optimization Formula

To ensure the kitchen island does not overcrowd the kitchen space, it’s essential to follow the space optimization formula. The ideal size of the island should follow the rule: Island area ≤ Kitchen total area × 10% + 2㎡ (reserved for the social area).

For example:

In a 15㎡ kitchen, the maximum size of the island is 15×10% + 2 = 1.7㎡.

In a 25㎡ kitchen, the maximum size of the island is 25×10%+2 = 2.5㎡.

Seating Ergonomics

Ergonomic Triangle Area

In the design of a kitchen island, creating an ergonomic work triangle is crucial. The work triangle, composed of the sink, stove, and island, is the key to efficient kitchen operations. According to ergonomic principles, the distance between each side of the triangle should be between 1.2 - 2.7 meters.

Compact Layout (1.5 meters): In a compact layout where the sides of the work triangle are around 1.5 meters, the efficiency of movement is reduced by about 30%. This is because the limited space restricts the smooth flow of movement between different work areas. For example, when cooking, the cook may have to constantly squeeze between the stove and the sink, wasting time and energy.

Standard Layout (2.4 meters): A standard layout with sides of the work triangle at around 2.4 meters can increase the smoothness of operation by 55%. With a more reasonable distance, the cook can move freely between the stove, sink, and island, improving cooking efficiency. For instance, it becomes easier to transfer ingredients from the sink to the stove for cooking, and then to the island for plating.

Height Differential System

Standard Operation Area: The standard height for the operation area of a kitchen island is 91 cm. This height is designed to match the natural height of a person’s arms when standing, allowing for comfortable chopping, mixing, and other food - preparation tasks without excessive bending or stretching.

Bar Dining Area: For the bar - style dining area on the kitchen island, the height is usually set at 107 cm. This height is coordinated with 65 - cm high stools, ensuring that when people sit, their feet can rest comfortably on the footrest of the stool, and the height of the tabletop is suitable for eating and drinking, providing a relaxed dining experience.

Dining Table Extension Area: If the kitchen island serves as an extension of the dining table, the height is typically 75 cm. It is important to maintain an 18 - cm drop compared to the main island surface. This height difference not only creates a visual distinction between the two areas but also ensures that the dining experience is comfortable, with enough knee space for diners.
