What Size Cut Out for a Gas & Induction Hob? A Comprehensive Guide

 

To help you navigate the specifications of your new appliance, here is a quick guide to common hob dimensions:

  • Overall Dimensions: The total physical size of the hob, including its height, width, and depth. For example, the FUJIOH FH-ID5125 induction hob has overall dimensions of W288 x D520 x H60, while the FH-GS7030 SVGL gas hob is W880 x D520 x H171.
  • Cut-out Dimensions: The precise size of the opening in your countertop required for the hob to be installed. For example, the FH-ID5125 hob requires a cut-out of W268 x D500, while the FH-GS7030-SVGL needs a W700 x D400 cut-out.
  • Overlap/Clearance: The space around the cut-out that the hob’s surface extends over, which is necessary for a seamless and secure fit. The difference between a hob’s overall dimensions and its cut-out dimensions accounts for this overlap.

Deciding on a new cooktop for your kitchen involves several important considerations beyond just its appearance. 

Unlike a freestanding stove, which is a single combined unit, a separate hob allows for significant flexibility. Because the hob is independent of the oven, you can integrate it into your countertop at a location and height that precisely suits your cooking preferences, allowing you to create a kitchen layout tailored to your needs. Whether you’re simply replacing an existing cooktop or undertaking a full kitchen remodel, a critical step is understanding the appliance’s specific dimensions, particularly the cut-out size needed in your countertop. 

This precision is vital for both gas hobs and induction hobs since knowing the exact cut-out required for an induction hob, or the dimensions for a gas hob, ensures a seamless installation, optimal performance, and safety for your new kitchen appliance.

So, what is the standard cut-out size for both gas and induction hobs?

Why Hob Size and Dimensions Are Important

But first, why is understanding hob size and dimensions so important when choosing a new cooktop? 

The answer lies in both efficiency and how well your new appliance integrates into your daily kitchen routine. 

Selecting the right size ensures your gas and energy are used optimally; you won’t waste gas and power on an unnecessarily large hob, nor will you struggle with limited space on a smaller one. For instance, for induction hobs, choosing a unit with the correct number of zones and power draw (amperage) prevents unnecessary energy consumption and ensures that the power you do use is channelled efficiently without overloading your system. For example, a 2-zone induction hob typically requires around 15 amperes (based on 230V), whereas a larger 3-zone model might require around 30 amperes. A precisely sized hob also guarantees a seamless fit within your existing kitchen layout, contributing to a cohesive and attractive appearance. 

Ultimately, getting these measurements right makes cooking easier and more enjoyable, enhancing the overall functionality of your kitchen space.

Understanding Standard Hob Sizes for Kitchen Integration

Hobs for kitchen integration come in various configurations for both gas and induction models

For FUJIOH induction hobs, for instance, popular dimensions include space-saving options like the FH-ID5125. This compact domino induction hob features two cooking zones (W288 x D529 x H60) for smaller counters. For those requiring three or more zones, we offer larger options (W590 x D520 x H60 or W590 x D520 x H62). Larger options are probably available in the market for those needing five or six cooking zones.

Similarly, gas hobs vary in size based on their burner count. A single-burner unit like our Domino Gas Hob with 1 Burner FH-GS2515 SVGL is W310 x D520 x H158; a two-cooking zone Domino Gas Hob model is W310 x D520 x H149; and a three-cooking zone option, like the FH-GS7030 SVGL, is W880 x D520 x H171.

However, we strongly recommend that you consult individual product manuals for precise measurements.

Key Considerations for Cut-Out Dimensions and Installation

Installing any hob requires precise attention to the cut-out dimensions in your countertop. This opening’s exact size must meticulously match the manufacturer’s specifications for your chosen gas or induction hob, ensuring a proper and secure fit. It’s helpful to note that the hob’s overall appliance dimensions typically differ from the cut-out, as the cooking surface is designed to extend slightly beyond the opening. This design allows for seamless integration and a clean finish with your countertop.

For example, the FUJIOH FH-ID5125 induction hob measures W288 x D520 x H60 but needs a W268 x D500 cut-out. Similarly, the FH-ID5120, with overall dimensions of W650 x D430 x H65, requires a W570 x D375 cut-out.

In addition, installation requirements vary depending on the hob’s edge design. Some hobs might be designed with a raised metal trim that secures the unit and covers the edge of the cut-out for a finished look. Others feature a frameless design, like FUJIOH hobs with bevelled edges, where the glass surface sits directly on the countertop. If replacing an existing unit, ensure compatibility with the current cut-out and any former frame.

How Much Space Does Your Hob Require?

Creating a comfortable and safe cooking zone means ensuring adequate space around your hob, which also helps your appliance last longer.

You’ll want clear areas on both sides for effortless cookware handling and food preparation; for instance, induction hobs like the FH-ID5120 typically need at least 5cm around the cut-out. Your work surface should also be sturdy, with a minimum thickness of 30mm, and made from a heat-resistant material.

For gas hobs, specific clearances are also necessary. Ensure installation in a well-ventilated room, complying with local regulations, and avoid placing near anything flammable like curtains. A gas hob like the FH-GS7030 SVGL, for instance, requires at least 200mm from the side walls and 70mm from the rear. Underneath, a thermal protection barrier, providing about 10-15cm of clearance from any underlying unit, is advisable for air circulation and protection. Overhead, allow sufficient space between the hob and any wall cupboard or extractor hood (e.g., 750mm for FH-GS7030 SVGL) for proper ventilation and to prevent heat damage. 

And for island installations, remember that specific requirements might differ. As such, always refer to your hob’s user manual for precise, model-specific measurements to guarantee safety and longevity.

Selecting the Right Hob Size for Your Household

When it comes to selecting the ideal hob size for your household, it truly comes down to your personal cooking habits, the available space in your kitchen, and your preferred culinary style. 

Think about how often you cook, whether you prepare large family meals, or if you simply need a compact solution for occasional use. You should also consider whether you live in an HDB or a private home. For example, a powerful induction hob like the FH-ID5230, which requires a 30-ampere rating, may not be suitable for some HDB flats due to the risk of overloading. For more information on this, check out our induction hob buying guide.

Of course, understanding what the standard dimensions of a hob are, and whether hob cut-outs are standard sizes, becomes crucial here. While there are common ranges, precise measurements vary by model and manufacturer. 

Considering these factors will guide you toward a hob that perfectly complements your kitchen, ensuring you have the right number of cooking zones and adequate workspace.

Once you’ve determined the ideal size and type of hob for your kitchen, choosing a brand that delivers on quality and ease of use becomes the final step. With FUJIOH hobs, you can cook with confidence, knowing you’re investing in an appliance designed to simplify your culinary tasks.

Our induction hobs, for example, feature high-quality SCHOTT CERAN ® Ceramic Glass surfaces that are not only remarkably easy to maintain. Since heat is only generated at the bottom of the pot, you’ll never see the severe, baked-on stains that occur on conventional stoves. Major and minor spills can also be cleaned up immediately, ensuring your cooktop maintains its pristine appearance for years. 

Beyond durability, FUJIOH hobs boast a minimalist design equipped with user-friendly features, complementing any modern kitchen aesthetic.
