What is the size of a double built-in induction hob? Will it fit in your kitchen space? Choosing the wrong size means having to cut the countertop again or being unable to install the hob in the prepared position. Therefore, this article will summarize all the overall measurements, the corresponding sizes of the double built-in electric hob that need to be cut into the stone, and the most important notes before installation.
Common sizes of double built-in induction hobs on the market
The sizes of double built-in induction hobs on the market today are not uniform among brands but are divided into many groups depending on the number of cooking zones and product segments. Understanding these size groups helps you compare them immediately with the actual countertop area before making a purchase decision. In addition to checking the measurement specifications, you also need to equip yourself with notes when buying induction hobs to ensure you choose a product with suitable power and features for your cooking needs.
The most common size of double built-in electric hobs today is the 2 cooking zone type, divided into 3 main groups based on the length of the glass surface:
- Small double induction hob with 2 cooking zones (approximately 600 x 360mm): Suitable for small kitchens, studio apartments, or limited cabinet space. With a length of only 60cm, this type can fit on many standard kitchen countertops without needing to cut or expand. The cooking zone diameter is usually smaller, suitable for medium-sized pots and pans from 20-24cm.
- Standard double induction hob with 2 cooking zones (730 x 430mm): This group of double built-in electric hobs is standardized and most popular among manufacturers in the Vietnamese market. The 73cm glass surface allows two cooking zones to have a large enough diameter to use 28-30cm pans. Most double induction hobs from Bosch (except for the large model), Electrolux, Beko, and domestic brands like Sunhouse, Pramie fall into this group.
- Large double induction hob with 2 cooking zones (750 x 450mm): This group of high-end double built-in electric hobs is commonly found in imported European models. With a width of 45cm, this type requires the kitchen countertop to be deep enough — usually from 60cm upwards — to ensure ventilation space and safe installation. Bosch PPI82560MS is a typical example with dimensions of 780 x 450mm.
The size of built-in induction hobs also follows the common sizes mentioned above.
In addition to the size factor, the large hob segment often comes with strict requirements for durability and component standards. If you are aiming for high-end imported products, referring to experience in buying German induction hobs will help you understand more about quality certifications as well as how to identify genuine E.G.O circuit boards or Schott Ceran glass surfaces to make the best choice.
Size of the cutout for double built-in induction hobs
One of the most common mistakes when installing built-in hobs is confusing the overall size of the hob with the size of the cutout in the stone. This is an important distinction – cutting incorrectly once on a granite or high-quality artificial stone countertop is very difficult and costly to fix.
How to calculate the cutout size from the overall size
The edge of the glass surface or the hob frame needs to rest on the stone surface to keep the hob stable, so the cutout must always be smaller than the overall size. The most common practical formula is:
| Cutout size = Overall size – (40mm – 60mm) for each dimension |
For example: a hob with an overall size of 730 x 430mm typically has a standard cutout size of about 680-695mm x 370-395mm, depending on the specific model. The allowable error when cutting stone is a maximum of 1 – 2mm – cutting too wide beyond this limit causes the hob to be unstable or may crack the glass surface during installation and use.

Common mistakes when measuring and cutting stone
The most common mistake is measuring the size according to the catalog and then cutting exactly that overall measurement, overlooking the edge that needs to rest on the stone surface. Some workers who are not familiar with installing built-in induction hobs may confuse these two parameters, leading to a cutout that is too large, causing the hob to be unstable. Additionally, it is necessary to place the hob into the cutout before applying adhesive to ensure a snug fit. Each manufacturer has a technical specification sheet (installation guide) that accompanies it – this is a document that should be referenced beforehand, and one should not rely entirely on the general formula.
Below is a table of cutout sizes for double built-in induction hobs and built-in electric hob sizes according to common overall dimensions:
| Size of double built-in induction hob | Cutout size for double built-in induction hob |
| 600 x 360mm | 560 x 320mm (±2mm) |
| 730 x 420mm | 680 x 370mm (±2mm) |
| 730 x 430mm | 695 x 395mm (±2mm) |
| 750 x 450mm | 685 x 385mm (±2mm) |
| 780 x 450mm | 720 x 395mm (±2mm) |
Frequently asked questions about the size of built-in induction hobs and built-in electric hobs
What is the standard size of a double built-in induction hob?
The most common size of double built-in electric hobs in Vietnam is 730 x 430mm (length x width). There is also a small size of 600 x 360mm for small apartments and a large size of 750 – 780 x 450mm for high-end imported models.
What is the cutout size for a double built-in induction hob 730 x 430mm?
The standard cutout size is 695 x 395mm (±2mm), not cut according to the overall dimensions. The edge of 17 – 18mm on each side needs to rest on the stone surface to keep the hob stable.
What space is the small double built-in electric hob size 600 x 360mm suitable for?
Suitable for studio apartments, kitchens under 6m², cabinets with a depth of less than 55cm. These hob models have smaller cooking zone diameters, not suitable for using large pans over 26cm frequently.
What is the allowable error when cutting stone ?
A maximum of 1 – 2mm. Cutting wider causes the hob to be unstable on the stone surface, which may lead to cracking of the glass surface over time due to uneven pressure when placing heavy pots.
Understanding the size of double built-in induction hobs – both the overall measurements and the corresponding cutout sizes – is an essential step before installation or purchasing a hob. The standard size group of 730 x 430mm is suitable for the vast majority of Vietnamese kitchen cabinets and is supported by many brands; the large size group of 750 x 450mm is more suitable for wider hobs and higher cooking needs. Regardless of which type you choose, always compare the technical specifications according to the specific model with the actual space before cutting the stone – one correct measurement can avoid many hassles later.
