Welcome to the Truss Material Calculator Hub

Building a roof involves more than just timber and nails—it requires precision, planning, and the right materials in the right quantities. Whether you're a builder, designer, or an owner-builder planning your own project, our collection of easy-to-use calculators is here to simplify the process.

This site provides a range of practical tools designed to help you estimate the materials required to erect roof trusses for residential construction. From calculating the number of bottom chord runners to working out valley boards, saddle restraints, or ridge lengths, each calculator is tailored for real-world jobsite needs. Simply enter a few measurements or selections, and get clear, usable results to help with ordering, quoting, and planning.

You won’t need to sift through complex engineering documents or waste time on guesswork. Our tools are built with Australian construction standards in mind and are regularly updated to reflect best practices. Most importantly, they’re free to use and accessible from any device—whether you're in the office, at home, or on site.

If you're just getting started, head over to one of the calculators in the menu above. Each tool includes clear instructions and optional working breakdowns, so you can double-check the logic if you want. We’re continually adding more calculators and features, so check back regularly—or reach out if there's a specific tool you'd like to see!
