Introduction: Efficient duct sizing is paramount for maintaining optimal airflow in HVAC systems, ensuring peak performance and energy efficiency. The Online Duct Size Calculator, tailored for airflow and velocity considerations, provides personalized recommendations to assist HVAC professionals and enthusiasts in selecting the ideal duct size. By incorporating the required airflow in cubic feet per minute (CFM) and desired velocity, this online tool aids users in achieving effective ventilation and climate control.

Formula: The calculator employs the airflow in CFM and velocity parameters to calculate the recommended duct size. This calculation involves dividing the airflow by the velocity, resulting in a duct size that maintains the desired airflow velocity for efficient ventilation.

How to Use:

- Enter the required airflow in cubic feet per minute (CFM).
- Enter the desired velocity in feet per minute.
- Click the “Calculate” button to obtain the recommended duct size in square inches.

Example: For instance, if the required airflow is 1200 CFM and the desired velocity is 400 feet per minute, the online calculator will instantly calculate and display the recommended duct size.
