Choosing the size of the kitchen chimney is very crucial. A kitchen chimney is not a thing that you can buy every day. So whenever you are going to buy a new chimney it is very necessary that you should know what size is perfect for your needs and kitchen size as well.
Many people just go to the market and buy a kitchen chimney without even knowing what kind of chimney they should buy or even what is the size of their kitchen. If you are one of those people then this guide is only for you.
There are three main points that you should keep in your mind while choosing the size of the chimney:
- The size of your kitchen
- The type of cooker that you have
- The number of burners on your cooker
What Type of Kitchen Chimney is Best for Your Kitchen?

Before you decide on the size of the chimney, you must know what type of chimney you should have for your kitchen. The most common types of chimneys are the wall-mounted chimney and the island chimney.
Wall-Mounted Chimney
The wall-mounted chimney is the most convenient type of chimney to have in your kitchen. It is easy to install and does not require a lot of maintenance. However, it is important to note that this type of chimney is not suitable for all types of kitchens. If your kitchen is small, then the wall-mounted chimney may not be the best option for you.
Island Chimney
This is another type of chimney that is commonly used in kitchens. It is mounted on the island and can be easily moved around. However, it is not advisable to use this type of chimney in small kitchens as it can take up a lot of space.
Moreover, it is important to check the size of the chimney before you buy it. The size of the chimney should be based on the size of your kitchen and the number of burners that you have in your kitchen.

Factors that you should know before buying the chimney
Here are the factors that you should keep in mind whenever you decide to buy a new chimney.
The size of the room
In general, a larger room will require a bigger chimney. But there are other important factors to consider as well.
The height of the ceiling
The taller the ceiling, the more air volume in the room and the more heat that is produced. The rule of thumb is that for every foot of ceiling height, you need 1 square foot of the chimney. So, if you have an 8-foot ceiling, you need an 8-square-foot chimney.
The type of fire
The type of fire you are burning will also affect the size of the chimney. A wood-burning fireplace produces more smoke and needs a bigger flue than a gas fireplace.
The manufacturer’s recommendations
Most chimney manufacturers will have specific size recommendations for their products. Be sure to follow these when choosing a chimney.

Frequently Asked Questions
Is a 60 cm chimney enough for a 3 burner gas stove?
Generally speaking, the 60 cm chimney is enough for the 3 burner gas stove. But to be on the safe side, it is always good to know the output of your stove (in terms of BTUs) and buy a chimney that can move at least that much air every hour.
How do I know what size my stove is?
The size of your stove is generally determined by the BTU output. To find out the BTU output of your stove, check the owner’s manual or consult with the manufacturer.
How do you measure a chimney’s width and depth?
To measure a chimney’s width, use a tape measure to find the distance between the two outermost edges of the chimney. To measure the depth, use a tape measure to find the distance between the top of the chimney and the bottom.
What is the right height for a chimney?
There is no definitive answer to this question, as the right height for a chimney will vary depending on the specific installation. However, as a general rule of thumb, the chimney should be at least two feet taller than the highest point of the roof.
