I thought it would be a useful idea to post here a guide to the IRCSSA international classes.
Of course you can build to any shape and size you desire but it makes a whole lot of sense (to me anyway) to stay within established guidelines.
Class Length Beam Height
1 750mm 500mm 1m
2 1m 750mm 1.5m
3 1.5m 1m 2m

I will try to post other links here when I can get the hang of doing it.
