Let me make myself clear, 13 cm IS INDEED a great amount. But thinking logically, if 13 is so good, just make another mock of you with +2/+3 more cm. It won't make THAT much difference in the eye BUT a huge difference around people or for your own mental being. Also, yes, shorter people 90% can add 13-15(maybe 16 if u cna pull it off) and be acceptable and tbh normal looking.
Just go around the metro/buss or any bussy area and look around and find short men. I guarantee you every one of em can add 13-15cm(just imagine em). The ONLY times thwy can't is they are extremely skinny/narrow/too short(for example a guy 5'5-5'8 could add 13cm whereas i have yet to see sb 5'0 being okat with that lengthening.)
Last thing I wanna say, in the real world no one notices proportions. Legit no one. I have shown pics of apo(the ones where he looks weird) to 24 people(friends and family members) not a SINGLE one of em say smth. All they said was *he looks handsome and strong* or the other end of the spectrum *abit feminine*. So all in all if you have basic muscle+wide(dont stress this enouph u know what i mean) + a minimum height of 5'4-5'8 go for it.
