You can do this by measuring the area that needs to be cooled or heated and then calculating the volume of air that needs to flow through it. You can begin designing the ductwork once you have that information.

You’ll need to consider the type of material you’re using, the airflow, and the bends and curves in the duct. You’ll also need to ensure that the duct is adequately supported so it doesn’t sag or fall.

If you’re unsure how to do all this, don’t worry—plenty of software programs can help you out. And once you’ve got your design finalized, you can create a shop drawing that will show your contractor exactly what needs to be built.
