Most of them are 5/16 with a few 1/4 thown in the mix. Length is how anal you are about having too many threads stick out of the nut after it is tight.

Some guys like to use 1 inch long bolts because it is easier to get a nut an washer on if the metal isn't all up real close together but it looks rather crude workmanship wise with way too many threads showing.. You don't need anything more than the grade 2 plated bolts out of the bulk bins that sell by the pound at ACE and a lot of other places. I'd just buy a a hand full of 1/2 inch long, 3/4 inch long and 1 inch long and fit the to work and look the best as I went.
