How to calculate duct branch coverage
This calculator finds duct branch coverage by dividing a total area or amount by the coverage provided per unit — useful for planning how many branch runs or diffusers a system needs.
How the calculation works
Coverage = Total area/amount ÷ Coverage per unit.
Example
2,400 sq ft of conditioned space with each branch covering 300 sq ft: Coverage = 2,400 ÷ 300 = 8 branches.
Frequently asked questions

Pro Tips for Duct Branch Coverage
- Confirm your coverage-per-branch figure accounts for your specific diffuser type and airflow rate, since this varies by equipment.
- Room layout and ceiling obstructions often dictate branch routing as much as raw coverage math — use this as a starting planning figure, not a final design.
Common Duct Branch Coverage Mistakes to Avoid
- Treating a rough coverage estimate as a final duct design without checking actual room-by-room airflow requirements.
