Range Hood Duct Size Complete Guide (With Examples!) (2022)
While a duct sizing calculator built for a specific type of ductwork is the best possible method for sizing ducts, the attached chart can be used in most single story homes with a centrally located unit, and reasonable length duct runs. Most technicians are skeptical about these numbers, especially on the Return air side of the system.

1. Calculate the CFM for Each Room Most HVAC units are designed to have a 400 CFM of airflow for every 12000 BTU or 1 ton of cooling capacity and 12000 BTU divided by 400 CFM is 30. So, identify the BTU needed for each room and divide it by 30 to get the required CFM for the respective room.

How to Use: Enter the airflow in CFM. Enter the air velocity in FPM. Click the "Calculate" button to find the recommended duct size. Example: For instance, if the airflow is 1200 CFM and the air velocity is 800 FPM, the calculation would be: (1200 / 800) * 144 = 216. Therefore, the recommended duct size is 216 square inches.
