Just saw your update and wonder if I missed this in the plans - going to look shortly -- but should I be planning 2x10 loft joists instead of 2x8's? It's a 'sleeping' loft.
Thanks
Here's a handy calculator that gives you maximum spans. Just plug in the info and it spits out the answer. [cool]

Cool thanks!
13'11" for 2x8 with a live load of 30 and a dead load of 10 -- I think I read somewhere you need a live load of 30 in order to walk on.
So, my span is 13' -- any reason I should not use 2x8's then?

John? I went looking again and the plans show the loft materials list with 2x8's which using the calculator (assuming I'm doing it right) indicates can span the 13' I need to span with loads of 30 psf -- if that's correct for a sleeping loft let me know.
I've got a 2x10 band joist in so can put in 2x10's but obviously don't want to ;) unless there is a risk of failure using the 2x8's.
Thanks

Bump
Bueller, Bueller?
Elsewhere it was confirmed that DF#2 2x8's spanning 13' on 16" centers would be fine for a sleeping loft -- I cam back today only to remind myself -- thanks!
