The bike you linked has 26" wheels, that is not the frame size. I would contact the seller and ask the actual frame size. I'm 5'4" and, when I ride a 26" wheeled bike, I need a small frame, 15-17 inch size.
Can I ask why you want a full sized folding bike instead of one with 20" wheels? It is probably going to be pretty heavy and only fold in half so not all that space-saving.
