About MGP10 Span Tables
MGP10 Span Tables is an independent, plain-English guide to understanding and using MGP10 timber span tables — built for owner-builders, apprentices, carpenters and anyone trying to size framing timber correctly.
Span tables are one of the most useful tools in residential construction and one of the most misunderstood. Our goal is to demystify them: what the MGP10 grade actually means, which variables drive a lookup, and how to read the tables without falling into the common traps that undersize a frame.
What we are
- A clear set of educational guides on MGP10 and span tables.
- A Span Spec Builder that assembles the exact parameters for your lookup.
- Hand-picked framing tools and reference recommendations.
What we are not
We are not engineers, and this site is not engineering advice, structural design, or a substitute for the official standards. We do not publish allowable spans, because the correct figure depends on the current AS 1684 tables for your exact situation and must be confirmed by a qualified professional. Think of us as the guide that helps you ask the right questions and arrive prepared.
Our approach to accuracy
We ground our explanations in the recognised Australian timber-framing framework — AS 1684 (Residential Timber-Framed Construction), the engineering standard AS 1720.1, and the National Construction Code. Standards are revised, and your situation is unique, so always work from current documents and professional advice.
