About this tool

Welcome to the Online Duct Sizing Calculator!

This free, easy-to-use ductulator helps you quickly calculate duct velocity and pressure drop based on design airflow — no charts, no guesswork, and no physical duct wheel required.

Ductulator.com has been around since 2017. It started as a simple web-based tool created by a recent engineering graduate who wanted a faster way to size ducts without carrying a physical ductulator or installing software on company computers. What began as a personal solution quickly found a wider audience — students, designers, contractors and experienced engineers alike began using the calculator as part of their everyday workflow.

Today, the tool continues to do what it was originally built for: help engineers and contractors get answers quickly and confidently. So they can focus on what matters more!
