In the actual quote from wikipedia regarding the above mentioned apocryphal book. He was described as 'middling', not short. ,,,
"Paul is given a full physical description that may reflect oral tradition: in the Syriac text "he was a man of middling size, and his hair was scanty, and his legs were a little crooked, and his knees were projecting, and he had large eyes [8] and his eyebrows met, and his nose was somewhat long, and he was full of grace and mercy; at one time he seemed like a man, and at another time he seemed like an angel.""
fwiw.
