A duct size calculator, commonly known as a ductulator, depends on factors like the size of the space you’re heating or cooling, air flow velocity, friction loss, and available static pressure of the HVAC system.
Time Saver:If you’re looking for a quick & easy calculation and already know the principles of CFM and ACH, use the Navigation tool to jump to thePick HVAC CFM Calculatorwhich gives CFM needed based on the number of ACH your space requires. OK, for most of us, let’s take it a li...
This is a simple duct size calculator where you can specify the total airflow in CFM (or L/s), the aspect ratio, and either the total velocity of air or the friction loss per 100 feet (30 meters). The results include both the exact and rounded height and width (or diameter) dimensio...
