I don't know about those two sizes but I did by a large size jacket. The arm pit to arm pit size on the large is 25 inches. I wear either a 44R or 46R in sport coats and this large jacket is just about perfect size for me. This is not the size you are asking about but it gives you some perspective on one size up from what you are looking for.
