Is this large enough/tall enough?

I just took in a hedgie today after a friend decided that she wasn't getting enough attention at her own house. I plan on acquiring a sheet of coroplast and folding a cage for her. It's dimensions would be 50" long, 20" wide, and 14" tall. Would this provide enough room for a single 2 year old, petite, active hedgie to roam as well as contain her?



Thank you for any advice. She is currently being housed in a 20 gallon tank but I don't like the poor ventilation or the small foot print. I also plan to use fleece bedding in the majority of the cage and give her a small 14" long, 14" wide, 1" tall tray of bedding to potty/play/whatever in.
