Fire Door Dimensions

Fire doors are critical structural elements in buildings, ensuring safe evacuation in emergency situations. Designing these doors with the correct dimensions is extremely important for people to exit quickly and safely in case of a fire. In Türkiye, fire door dimensions are determined within the framework of the Regulation on Fire Protection of Buildings (BYKHY). The dimensions of fire exit doors vary according to their area of ​​use.

2. Fire Door Dimensions for Special Areas

Some special use areas may require fire doors of smaller or larger dimensions. Dimensions for these areas can be determined as follows:

Narrow Spaces: In small offices or low-density areas, the door width can be at least 70 cm. However, suitability for escape routes should be checked in such areas.

Accessibility for People with Disabilities: In areas suitable for use by people with disabilities, door widths should be at least 90 cm to allow wheelchair access.

3. Importance of Fire Door Dimensions

Choosing the correct fire door dimensions directly affects several important factors:

Ease of Evacuation: Wide dimensions allow crowds to exit quickly in case of fire. This plays a critical role in ensuring people’s safety.

Regulatory Compliance: Fire door dimensions must comply with the fire escape plan specified in the architectural projects. This is necessary to ensure both building safety and compliance with regulations.

Fire Door Price: Standard-sized fire doors are generally more affordable. However, custom-made doors can increase costs due to increased sheet metal and paint consumption.

Installation and Usage Area: Custom sizes may be preferred for narrow spaces, but this requires project designer approval.

Fire doors vary in price depending on their dimensions. In general:

Standard Size Doors: More affordable and can be delivered quickly from stock.

Custom Size Doors: Prices may increase by 10% – 25% due to the increased amount of sheet metal used depending on the desired width and length.

Double Leaf Fire Doors: These doors are more expensive than single-leaf models due to the larger number of materials and accessories required.

5. Fire Door Size Selection

When selecting a fire door, not only the price but also the dimensions and certification suitability should be considered. The most commonly preferred standard sizes in Turkey are 80×200 cm, 90×210 cm, and 100×210 cm. For buildings requiring larger passage areas, double-leaf fire doors in sizes 120×210 cm and 140×210 cm are preferred.
