Series overview
W12 series
The W12 series groups AISC W-family shapes that share the same nominal-depth designation prefix. Weights and actual depths still vary within the series, so use the table below to compare candidates before analysis.
The AISC W12 series contains 29 published sections ranging from 14.00 to 336.00 lb/ft . Actual depths range from 11.90 to 16.80 inches, despite the shared W12 nominal designation .
- Lightest W12
- W12X14
- Highest Ix
- W12X336
- Shallowest actual depth
- W12X14
- Widest flange
- W12X336

Questions & answers
W12 FAQs
What is the W12 series?
It is the set of published AISC W shapes whose designation begins with W12. Members share a nominal-depth label but can differ in weight, actual depth and properties.
Why do actual depths differ within W12?
The number in the designation is nominal. Published overall depth varies by weight. Always use the tabulated depth for clearance and detailing.
How should I choose among W12 weights?
Compare weight, Ix, Sx, flange geometry and project constraints, then analyze finalists under the same span and loads. There is no universal “best” section.
Can I analyze a W12 section in Optimal Beam?
Yes. Select a designation above and choose Analyze to load its properties into the beam calculator.
