You already know how to size a duct. This agrees with your wheel, and then answers the part the wheel cannot. Type the airflow and the friction rate. DuctWise gives you a round size the supply house actually stocks, the velocity that size will really run at, and the static the whole run will cost you — off the ASHRAE friction chart for galvanised round duct, the same chart the ductulator in your door pocket is printed from. THE PART A WHEEL CANNOT DO The round size was never the hard part…

What's new
Version 1.2 · 20 Oct 2026 · 2 days ago
New in 1.2: • Fit: see whether the duct fits your joist bay or ceiling space, and the shape to run instead when it doesn't (rectangular, flat oval, or two runs). • Static: turn your blower's available static into the friction rate to size with, and see what's left for the run. • Flex or metal: size flex duct at its real roughness and see the metal equivalent. • Job: save each run, keep the list per job, and share a one-page duct schedule PDF. • The first screen is clearer: one stocked size, the band check, then your inputs.
