Xiao's height is approximately 1.64 meters, which is about 5 feet and 4.65 inches. This measurement is based on in-game comparisons and is considered quite accurate by players since miHoYo has not officially released exact character heights. Some players previously thought he was shorter (around 1.58 meters), but the measured result of 1.64 meters is more widely accepted. Xiao's height is similar to other characters like the female Traveler, Kazuha, and Albedo, and is slightly taller than Razor.
