If you look on the outside of the pack on the lid, it will say if it is a terraplane, etc. It might help to list the size, can be found on the left side of the pack where the back of the pack meets the packbag as it sits facing away from you in a little whit tag. Will say M or L or some such. They are not fit based on height but by torso length corresponding to the frame size. The hip belt is also sized and can be found where the padded section meets the Velcro.
They are great packs!
