To pick the correct duct measurement for your property, you'll want to take into account the capacity within your HVAC unit, the selection and placement within your vents, as well as the friction decline brought on by bends, fittings, and obstructions as part of your ducts. You can utilize this on line calculator to assist you to figure out the ideal duct sizing for the system: Alternatively, You need to use this chart down below as being a reference:
