All 166 ITI sections in the Calcs.com library, with the section properties and characteristic values used to design them.
These are section properties and characteristic values, not allowable spans. A span depends on your loads, member spacing, and deflection limit, so it has to be calculated.
Every section below is built into the calculator. Enter your span and loads to see whether the section passes, and by how much.

Frequently asked questions
What sizes does ITI glulam, I-joist, LVL and sawn timber come in?
Calcs.com carries 166 ITI sections across Spec Joist®, Prolam®, Spec Frame®, Design Pine®, F7, Swelite®, Design Pine®, Prolam® Post, Spec Beam®, Flame Fixx dxf® BAL-40, Spec Chord®, eXtreme Beam®, eXtreme Joist®, Design Pine® Post, eXtreme Post®, Form Spec®, Cypress Gold® and Spec Lam®. Depths run from 44 mm to 400 mm (44, 65, 66, 68, 70, 88, 90, 95, 96, 100, 112, 115, 120, 130, 135, 138, 140, 150, 170, 180, 185, 190, 200, 230, 240, 255, 265, 280, 290, 300, 320, 330, 360, 400 mm), in breadths of 30, 32, 35, 42, 44, 45, 47, 51, 53, 58, 63, 65, 69, 70, 75, 80, 88, 89, 90, 95, 96, 97, 100, 112, 115, 120, 135, 140, 150, 185, 190 mm. Every one of those sections is selectable in the calculators listed on this page.
Is there a span table for ITI glulam, I-joist, LVL and sawn timber?
This page publishes section properties and characteristic values, not allowable spans. A span is not a property of the section: it depends on the loads you apply, the member spacing, and the deflection limit you design to, so the same section spans different distances on different jobs. Rather than reading a span off a generic table, select the ITI section in a Calcs.com calculator and enter your actual loads. The calculator checks bending, shear, bearing, and deflection and reports the governing limit.
