The beginner hoops are made with 3/4″ id 100 psi tubing at about a 37-39″ diameter. This is a great size and great weight to get you started. People who swear that they cannot hoop should give this hoop a try because it will surprise you with how easy it is!!
They collapse down to about a quater of their original size for each shipping and traveling! There is a blog post and video showing how to collapse and uncollapse the hoops.
