Span calculator for joists and rafters!

This seems to be pretty handy, it helped me pick out some lumber sizing...

...thought since it helped me, it might be of use to someone else too!

Thanks, gen2600.
Bookmarked that one. That may be a Godsend when I get to that point. Just took the class in Vegas June 4-5 so I'm not at the joist or rafter stage just yet...

Great job! You are likely in the planning stage, so, it's always the time!

You may want to get a set of plans that has all this info and get it engineered... I see some dangers in just using this table and going for it.
