Frequently Asked Questions (10)

Common questions and answers regarding this tool.

This reference guide (doubled 2x8 ≈6 ft, 2x10 ≈8 ft, 2x12 ≈10 ft max span) is a starting estimate only — final beam sizing depends on joist span, spacing, species, and local code tables.
Sistering (doubling/tripling) dimensional lumber increases the beam's load capacity and span rating beyond what a single board can safely carry.
