The Man United away shirts do not allow for 25 cm numbers. Thus the 16 cm junior size numbers come in handily. In the below example the letters are the standard adult size though, 5 cm.
In the case of the home shirt well, there is plenty of room so it is all about the proportions. Which size has the better proportions for the youth size shirt. 128 cm is definitely worthy of the 16 cm numbers. 140 cm is kind of the border line. It can swing both ways. 152 cm and up well adult size numbers actually fit quite well. Even on the youth 11-12 years kit.
