ANALYSIS OF THE UPPER MOON DEMONS’ HEIGHTS

Only five of the Upper Moon Demons were disclosed by the Kimetsu No Yaiba Fandom Wiki. The tallest Upper Moon that the Wiki revealed is Kokushibo, which has a height of 6 feet and 2 inches. Next, Kokushibo has a 1-inch height advantage over Doma.
Akaza was revealed to bear a 5 feet and 8 inches frame. Gyokko overpasses Hantengu’s height by two inches whenever Gyokko activates his True Form. But, Gyokko’s normal height is 4 feet and 11 inches.
Only Daki and Gyutaro’s heights were not revealed. With that said, we estimated their heights based on their appearance in the second season of the anime.
Based on the physical fight between Daki and Tanjiro, Daki is taller than Tanjiro’s 5 feet and 5 inches frame. If we disregard Daki’s Geta footwear, Tanjiro is on Daki’s eye level, giving Daki a 3-inch advantage.
In terms of Gyutaro’s height, we estimated his height based on his interaction with Tengen Uzui. Tengen is one of the tallest Pillars for his 6 feet and 6 inches frame.
Both of them were squatting in their battle, but it is evident that Tengen has a 1-inch height advantage over Gyutaro.
ANALYSIS OF THE UPPER MOON DEMONS’ AGES
All of the Upper Moon Demons’ ages were revealed by the Kimetsu No Yaiba Fandom Wiki. Kokushibo is the oldest demon since he bears an age of 480 years. He is followed by Hantengu, who is a 200-year-old Upper Moon Demon.
Both Doma and Akaza are 133 years old. In a similar case, Daki and Gyokko are both 113 years old. That said, they are the youngest Upper Moon Demons.
Last but not least, Gyutaro and Daki have a 13-year age gap; hence, Gyutaro is 126 years old.
