Kitchen Renovation Measurements: Countertop, cabinets, walkway dimensions

Kitchen trends are always changing as our homes and lifestyles are ever-evolving. However, one thing that will always be constant is the need for an efficient, comfortable kitchen. No one wants to have to bend forward too much, tiptoe to reach things or even squeeze through passageways. After you’ve done basic space planning, read on for a breakdown of the key kitchen renovation measurements and spatial requirements you need to know.

Kitchen Walkway Clearance

Minimum and ideal kitchen walkway width: 1 metre for one cook and 1.2 metres for two cooks

There isn’t a strict HDB regulation on walkway width in kitchens, but it must allow for safe movement and accessibility (especially for elderly residents) and adequate space for cabinet and appliance doors to open fully without obstruction.

In a galley-style kitchen in Singapore HDB flats, the recommended walkway clearance ranges from 90cm to 1m for one chef. If you often have two persons cooking and cleaning at the same time, you may need to factor 1.2m to 1.5m walkway clearance instead.

Kitchen Countertop Measurements

• Kitchen Countertop Height: 85 to 90 centimetres
• Kitchen Countertop Depth: 60 centimetres
• Kitchen Sink Countertop Width: 60 centimetres on one side of the sink and 45 centimetres on the other side
• Food Preparation Surface Width: At least 75 centimetres
• Cooking Surface Width: At least 30 centimetres on one side of the hob and 40 centimetres on the other side

When planning a kitchen countertop for an HDB flat in Singapore, several measurement considerations are essential to ensure functionality, comfort, and efficient use of space. The height of the countertop is a crucial factor, as it affects ease of use.

Kitchen Countertop Height

The standard kitchen countertop height in most HDB kitchens ranges between 850mm to 900mm (85cm – 90cm), which is suitable for the average user. For taller homeowners, a height of 900mm to 950mm may be more ergonomic, reducing strain while cooking or washing dishes.

Kitchen Countertop Depth

Another key measurement is the depth of the kitchen countertop, which determines the workspace available for food preparation and storage. The standard depth is 600mm (60cm), as this aligns with standard kitchen cabinets and built-in appliances such as hobs and sinks.

However, if space permits, a slightly deeper kitchen countertop of 650mm to 700mm (65cm – 70cm) can provide more working space without making the kitchen feel cramped. It is also important to ensure that the countertop depth allows for proper clearance of cabinet doors and drawers.

Kitchen Countertop Thickness

The thickness of the kitchen countertop varies depending on the material chosen. Most solid surface, quartz, and granite countertops range from 15mm to 30mm (1.5cm – 3cm) in thickness. For a more premium and durable finish, thicker materials of 40mm (4cm) can be used, especially for countertops that experience heavy use. The thickness also plays a role in the overall aesthetic of the kitchen, with slimmer profiles offering a modern look and thicker profiles providing a more substantial, luxurious feel.

Kitchen Bar Overhang

For kitchens that incorporate a bar counter or dining extension, the overhang measurement is another critical consideration. A typical overhang ranges from 250mm to 300mm (25cm – 30cm), allowing enough space for seating while maintaining balance and stability. If stools are placed underneath, it is important to ensure adequate legroom for comfortable dining.

Kitchen Cabinet Height from Countertop

The standard distance between the kitchen countertop and the bottom of upper cabinets should be around 450mm to 600mm (45cm – 60cm).

A lower height (closer to 450mm) makes items more reachable, while a higher placement (closer to 600mm) allows more room for kitchen appliances like kettles and blenders.

Kitchen Cabinet with Cooking Hood

If a cooking hood is installed, this clearance must accommodate it, with a minimum of 600mm above gas stoves and 450mm above induction cooktops.

The total height of top-hung cabinets typically ranges from 600mm to 900mm (60cm – 90cm), depending on kitchen size and storage needs. Taller cabinets maximise vertical storage, but they may require a step stool for access.

In kitchens with higher ceilings (2.6m and above), floor-to-ceiling cabinets (above 900mm) can be used for extra storage, but ensure they remain functional.

Kitchen Cabinet Depth

The depth of upper cabinets should be between 300mm to 400mm (30cm – 40cm). A depth of 300mm is standard and ensures that the cabinets don’t obstruct movement or make the kitchen feel cramped. For additional storage, 350mm to 400mm can be used, but it should still allow comfortable access to the countertop workspace. The depth must also align with the lower cabinets and appliances like range hoods.

Built-In Microwave Height

When installing a built-in microwave in an HDB kitchen, it is important to consider ergonomics, accessibility, and safety. Proper placement ensures ease of use while preventing strain or accidents when handling hot dishes.

For a built-in microwave, the recommended height from the floor is between 900mm and 1200mm (90cm – 120cm), allowing for comfortable access without excessive bending or reaching. Ideally, it should be positioned at or just below eye level, with a maximum height of 1400mm (1.4m) to ensure safe removal of hot food. If the microwave is placed above a countertop, there should be a clearance of 350mm to 450mm (35cm – 45cm) to provide sufficient workspace below while keeping it within easy reach. Placing the microwave too high can pose a safety risk, as handling heavy or hot dishes at an elevated position increases the chance of spills or burns.

Built-In Oven Height

For a built-in oven, the placement depends on whether it is installed under the counter or at mid-height. When installed beneath a worktop, the standard height is 600mm to 900mm (60cm – 90cm) from the floor. However, for better accessibility, particularly for those who prefer not to bend too much, a mid-height installation between 900mm and 1200mm (90cm – 120cm) is recommended. In some cases, eye-level installation is preferred, but the maximum height should not exceed 1300mm (1.3m) to ensure the oven door and trays remain easy to handle.

If a microwave and oven are stacked within a tall unit, the total height should not exceed 1500mm (1.5m), keeping both appliances within a comfortable and safe reach zone. Proper positioning also ensures a seamless workflow in the kitchen, improving both efficiency and convenience.
