Kitchen Chimney Size in Feet, Inches & CM – Complete Conversion Chart

What is the Ideal Size for a Kitchen Chimney?

Choosing the right size for your kitchen chimney is crucial for effective ventilation. The size of the chimney depends on the stove you use and your kitchen’s size. Here’s a quick overview of the most common sizes:

For 2-burner stoves: A 60 cm chimney is ideal.
For 3-burner stoves: A 90 cm chimney is the best option.
For 4-burner or larger stoves: You may need a 90 cm or 120 cm chimney.

The goal is to match the chimney width with the width of your stove for optimal suction and air circulation.

Still unsure, in this guide, we’ll help you determine the ideal kitchen chimney size with a comprehensive size chart, explain how to calculate the required suction power, and provide practical tips for choosing the best chimney for your needs.

Let’s dive in!

Why Kitchen Chimney Size Matters

A chimney that’s too small won’t cover the entire stove area, leading to poor suction. On the other hand, an oversized chimney may be inefficient or look awkward in a small kitchen.

Choosing the right size helps:

Improve air quality by capturing smoke and grease
Enhance energy efficiency
Prolong chimney life
Improve kitchen aesthetics

Kitchen Chimney Size Chart (Based on Stove Size)

The ideal kitchen chimney size typically depends on the size of your stove. Here’s a simple reference to help you choose the right size:

Stove Size	Recommended Chimney Size
2-burner	60 cm
3-burner	90 cm
4-burner+	90 cm or 120 cm

Matching your chimney width with your stove width ensures optimal smoke extraction and air circulation.

Chimney Size (cm)	In Feet	In Inches
60 cm	2 feet	24 inches
75 cm	2.5 feet	30 inches
90 cm	3 feet	36 inches
120 cm	4 feet	48 inches

How to Calculate the Suction Power Needed for Your Kitchen Chimney

The suction power of a kitchen chimney is essential to ensuring it effectively removes smoke, grease, and odors. Here’s how to calculate the suction power based on your kitchen size:

Find the volume of your kitchen (in cubic meters): Volume=Length×Width×Height
Calculate the recommended suction power: The ideal suction power for your chimney is usually 10 times the volume of your kitchen (in cubic meters). For larger kitchens or more intensive cooking, you can increase this value by 10-25%.

Example:

For a kitchen measuring 3x4x3 meters:

Volume = 3 × 4 × 3 = 36 cubic meters.
Recommended suction power = 36 × 10 = 360 CFM.
For heavy cooking, increase by 10-25%: 360 × 1.25 = 450 CFM.

How to Choose the Right Kitchen Chimney Size: A Simple Guide

Cooking Type	Kitchen Size	Burner Number	Recommended Chimney Size
Light Cooking (boiling, reheating)	Small (up to 8×8 ft)	2-burner	60 cm
Moderate Cooking (Indian cooking, stews)	Medium (8×8 ft to 10×10 ft)	3-burner	90 cm
Heavy Cooking (frying, tadka)	Large (10×10 ft or more)	4-burner or more	90 cm to 120 cm
Intensive Cooking (daily frying, heavy spices)	Any size	3-4-burner or more	120 cm

How to Use This Table:

Light Cooking: If you mostly do boiling, reheating, or light cooking with minimal smoke, you can opt for a 60 cm chimney.
Moderate Cooking: If you cook regularly with a 3-burner stove and have a medium-sized kitchen, a 90 cm chimney is ideal.
Heavy Cooking: For large kitchens or intense cooking styles like frying, using a 90 cm to 120 cm chimney ensures proper ventilation.
Intensive Cooking: If you cook with heavy spices and use the stove daily for frying, a 120 cm chimney is recommended regardless of kitchen size.

Comparison: 60 cm vs 90 cm vs 120 cm Chimney

Chimney Size	60 cm	90 cm	120 cm
Ideal For	Small Kitchens (≤100 sq. ft)	Medium–Large Kitchens (100–200 sq. ft)	Large Kitchens/Commercial (200+ sq. ft)
Burners	2–3	3–5	5+
Suction Power	700–1000 m³/hr	1000–1250 m³/hr	1200–1500 m³/hr
Mount Type	Wall-mounted	Wall/Island	Island/Built-in
Best For	Light frying, occasional Indian meals	Regular Indian cooking, tadka	Heavy frying, open kitchens
Popular Brands	Faber, Glen, Elica	Hindware, Elica, Bosch	Kutchina, Kaff, Faber
Price Range	₹6,000–₹10,000	₹9,000–₹18,000	₹15,000+

Wall-Mounted vs Island Chimneys: Do Sizes Differ?

Wall-mounted chimneys are ideal for traditional Indian kitchens with stoves against the wall. Most are 60–90 cm wide.
Island chimneys (for stoves in the middle) require wider sizes (90–120 cm) and higher suction because they’re exposed from all sides.

Does a Big Hood Size Mean Better Smoke Ventilation?

A bigger hood doesn’t always mean better smoke ventilation. The suction power of the chimney is the key factor that determines how well it removes smoke and fumes. So, while the hood size should match your cooktop, it’s the suction power that should be your main focus when choosing a chimney.

Choosing Hood Size vs. Suction Power Based on Cooking Style

It’s important to understand that your cooking style matters more than the size of your hood. For example, if you use a two-burner cooktop but do heavy frying, a larger hood won’t solve your ventilation issues. What you need is a chimney with high suction power to handle the smoke.

For light cooking on a small cooktop, you can go for a chimney with lower suction power. The key is to match the chimney’s suction power to your cooking habits, not just the size of the hood.

Key Takeaways

Hood size should match your cooktop, but suction power is the most important factor for effective ventilation.
A larger chimney hood is not necessary for light cooking. Focus on getting the right suction power for your needs.
For small kitchens, a compact chimney with high suction is ideal.

Conclusion

Selecting the right kitchen chimney size is crucial for ensuring your kitchen stays smoke-free and comfortable.

By matching the chimney size to your stove width and calculating the correct suction power based on your kitchen’s volume and cooking habits, you’ll enhance both the effectiveness and efficiency of your kitchen chimney.

Frequently Asked Questions (FAQs)

How do I calculate the right chimney size for my kitchen?

To determine the ideal chimney size, consider your stove size and kitchen layout. Here’s a quick reference:
2-burner stove: 60 cm chimney
3-burner stove: 90 cm chimney
4-burner stove: 90 cm or 120 cm chimney

What is the ideal suction power for my chimney?

The ideal suction power depends on your kitchen’s volume and cooking habits. As a general rule, multiply your kitchen’s volume (in cubic metres) by 10 to determine the required suction power in CFM. For more intensive cooking (frying, tadka), increase the suction by 10-25%.

How do I choose between a 90 cm and a 120 cm chimney?

A 90 cm chimney is sufficient for most kitchens with 3 or 4-burner stoves. If you have a very large stove or a spacious kitchen, a 120 cm chimney will provide better airflow and efficiency.
