This link has a detail of Jump Gates not always seen. It is a profile view and as close as you can get to a plan or cross section and provides detail of the sections making up the jump gate. Unfortunately even B5Tech.com is vague regarding the size of Jump Gates but the Cortez Jump Gate constructor or Explorer Class could fit through a Jump Gate, which is why I gave you the previous link.
Using the B5ccg view and the Largest EA ship profile you should get a rough scale for your design. I think that even JMS is unable to tell you the dimensions although the special effects guys might, but I've had no luck down that route.
