Floor Span Tables: I-Joist Simple Span Applications
1. Select the appropriate table based on the project design loads
2. Find a span that meets or exceeds the design span.
3. Read the corresponding joist series, depth, and spacing.
Caution: For floor systems that require both simple and continuous span joists, it is a good idea to check both tables before selecting a joist. Some conditions are controlled by simple span deflection rather than continuous span strength.
