Diego’s height was estimated by scaling his height difference relative to another character in the game named Faith, and also to a sitting bench in this Youtube The Guardians of Peace Gameplay Walkthrough (Android, iOS) – Part 1 Video.
Faith is an adult female who has physical features hinting her being African-American. Faith is very likely to have an estimated height range of around 5 feet and 4 inches since according to Medicine Net Article, African-American females will measure somewhere will 5’4.
Another point of reference would a sitting in the gameplay video. The bench should have a standard height of around 20 inches (50.8cm).
By observing Diego in the Gameplay Video, the bench’s height seems to be in the same line as the hip height of Diego [6:26] while also at the same time his maximum height peaks at Faith’s upper chest [8:17]. By using Hikaku Sitatter Height Comparison Chart Tool, we were able to figure out a rough scaling estimate for Diego based on his height relativity towards the bench and Faith.
A young male teenager who has a hip height of 20 inches and a maximum height relative to the upper chest of a 5’4 woman should be somewhere around the height of 130cm or 4’3.
