: Round ducts are generally the most efficient shape as they have the least surface area for friction. Key Formulas Used in Duct Sizers

Most digital duct sizers utilize the following core relationships to determine size based on required CFM (Cubic Feet per Minute): is airflow rate and is velocity). Circular Duct Area: Rectangular Duct Area: Ductsize - HVAC Duct Sizing and Analysis - Elite Software

: Offers a Ductulator Chart & Guide for those who prefer visual charts or manual calculation formulas over software. Why Accurate Sizing Matters Download Duct Sizer zip

While modern engineers often use mobile apps like Duct Sizer Lite or Duct Sizer , several established desktop programs are available for deeper analysis:
