Best Kitchen Chimney Size for Modular Kitchens

A modular kitchen looks clean and organised until the chimney does not cover the cooktop properly. Smoke escapes from the sides, grease settles on new cabinets, and the walls start yellowing within months. Most of this happens because the chimney is the wrong size for the cooking setup.

Kitchen chimney size depends on how wide your cooktop is, how your kitchen is laid out, and how intensely you cook. In Indian modular kitchens, where tadka, frying, and pressure cooking happen daily, getting the size right is the difference between a kitchen that stays fresh and one that constantly smells of last night's dinner.

Why Does Chimney Size Matter More in a Modular Kitchen?

Modular kitchens are built differently from traditional kitchens, and the wrong chimney size causes problems that go beyond poor ventilation.

Here is why size deserves more attention than most buyers give it:

• Cabinets are the first casualty. They sit close to the cooktop. Smoke and grease that escapes a narrow chimney settle directly on surfaces, damaging laminates, warping edges, and clogging hinges.
• Closed layouts trap everything. Most modular kitchens are enclosed. The chimney is the only exit for smoke, steam, and oil particles. An undersized chimney leaves fumes circulating inside.
• Multiple burners spread the smoke wide. Indian dinner prep often means 2 to 4 burners running simultaneously. A chimney that does not span the full cooktop width misses the outer burners entirely.
• Replacement is expensive. Changing a chimney in a modular kitchen means dismounting, modifying cabinet cutouts, and reinstalling. Getting the size right the first time saves money and rework.

How to Choose the Right Kitchen Chimney Size

The simplest rule: the chimney should be equal to or wider than the cooktop. Never narrower.

Here is how each standard size maps to common Indian cooktop configurations.

60cm: For 2 to 3 Burner Cooktops

A 60cm chimney covers most 2-burner and compact 3-burner gas stoves. It fits well in I-shaped, L-shaped, and parallel modular layouts where counter width is limited. Handles daily cooking with moderate smoke, including tadka, rotis, dal, sabzi, and occasional frying.

Best for: Small to mid-sized modular kitchens, budget-conscious households, and kitchens where wall space between cabinets is limited.

75/76cm: For Wider 3 to 4 Burner Setups

A 75cm chimney bridges the gap for 3-burner cooktops with wider burner spacing, or compact 4-burner hobs. It suits U-shaped and L-shaped modular layouts where 60cm feels tight, but 90cm looks oversized.

Best for: Medium-sized modular kitchens, families of 3 to 5 who cook daily with multiple burners.

90cm: For 4 to 5 Burner Cooktops and Large Kitchens

A 90cm chimney is designed for wide cooktops, built-in hobs with 4 to 5 burners, and open or island layouts where smoke travels further. Handles heavy Indian cooking with simultaneous frying, boiling, and grilling, plus festival and batch cooking.

Best for: Joint families, large modular kitchens, and island cooktop setups. A detailed comparison of how 60cm and 90cm chimneys perform in Indian kitchens helps clarify which size matches your cooking habits.

What Should You Check in Your Kitchen Before Deciding?

Before picking a size, walk through these checks with a measuring tape:

• Cooktop width: Place a tape across the full width, including the frame. A 3-burner stove is typically 60cm to 70cm. A 4-burner hob runs 70cm to 90cm. The chimney should match or exceed this.
• Gap between overhead cabinets: The chimney sits between two cabinet units. If the gap is exactly 60cm, a 60cm chimney fits. Wider gaps accommodate 75cm or 90cm without modification.
• Kitchen layout shape: I-shaped and galley kitchens suit 60cm. L-shaped and U-shaped layouts often need 75cm or 90cm. Island kitchens almost always need 90cm.
• Ducting distance: Measure from the cooktop to the nearest external wall. Shorter duct runs mean less suction loss. Optimal chimney placement guidance covers positioning and height in detail.
• Simultaneous burner use: If you regularly run 3 or more burners at once, the chimney must cover the full span. A 60cm chimney on a wide 4-burner hob leaves outer burners exposed regardless of suction strength.

What Other Factors Affect Performance at Each Size?

Chimney width gives you the right coverage. These additional specs determine how well it performs daily:

• Suction power: 1000 to 1200 m³/h for 60cm with moderate cooking. 1200 m³/h or higher for 90cm with heavy cooking.
  Matching suction to your kitchen and cooking style prevents under-performance and energy waste.
• Mounting height: 24 to 26 inches (60 to 65cm) above a gas cooktop. Too high reduces suction. Too low causes heat damage.
• Filter type: Filterless chimneys maintain consistent suction without clogging. Baffle filters need cleaning every 2 to 3 weeks.
• Motor type: BLDC motors draw less power and run quieter. For chimneys running 30 to 60 minutes daily, energy savings and noise reduction matter.
• Ducted vs ductless: Ducted performs better for heavy Indian cooking. Ductless suits apartments where external ducting is not possible.

What is Available Across Each Chimney Size?

All three standard sizes come with models suited for different cooking intensities and budgets.

Here is what you can expect at each width:

• 60cm: Pyramid, straight-line, curved glass, vertical glass, filterless auto-clean, and BLDC variants. Suction from 1000 to 1500 m³/h. Motor warranties range from lifetime (baffle) to 15 years (BLDC).
• 75/76cm: Filterless auto-clean with 1200 to 1400 m³/h, motion sensor controls, and 7-year motor warranty. Heat sensor variants that auto-adjust speed. BLDC models with inverter technology and a 15-year warranty.
• 90cm: Pyramid (1250 m³/h), straight-line (1000 m³/h), filterless auto-clean (1200 to 1500 m³/h), and BLDC (1400 m³/h with inverter). All major chimney types are available in this width.

All models use energy-saving LED lighting (1.5W to 2W). Select models support ductless recirculation with carbon filters.

Which Chimney Size Fits Your Kitchen?

The right chimney size protects your modular kitchen investment. Cabinets stay grease-free, walls stay clean, and the kitchen stays fresh even after heavy cooking. A 60cm covers most compact Indian kitchens with 2 to 3 burners. A 75cm fills the gap for wider 3 to 4-burner setups. A 90cm handles large cooktops, built-in hobs, and open layouts.

Start with your cooktop width, check your cabinet spacing, and pick from Glen's chimney range to find the right fit for your modular kitchen.
