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.
