it's been somthing that's bothered me for quite some time. i know ZUN had a small height chart around touhou 7 but i really want to know the height of every character just so i can get some perspective.
so to start with

Sukuna 87 cm or 1 inch tall
marisa is 130 cm
futo is also 130 cm
koishis 132 cm since the satori's are basicly twins im assuming Satori is also around 132 cm
nitroi 134 cm
miko is 142 cm
ichrin 143 cm
reimu 149 cm
Mokou 149cm
Mamazou is 151 cm
usami reinko is 153 cm
Kasen is 154 cm
hata no kokoro is 155 cm
byakuren is 157 cm
rinnosuke 195 cm confirmation needed
Doremy Sweet 243cm (Confirmation needed!)
Reisen is 135 cm (confrimation needed)
now for some guessing
ZUN stated that
Tall: Sakuya, Meiling, Yukari
however it is shown that yukari and sakuya are shorter then rinnosuke
although it might just be yukari using border manip in curiosities of lotus asia
Fairly Tall: Reimu, Yuyuko, Alice, Letty, Ran
so Yuyuko alice letty and ran might be around 149 cm confirmation needed
Fairly Short: Marisa, Youmu, Patchouli, Lunasa, Merlin
Youmu, Patchouli, Lunasa, Merlin 130 cm confirmation needed
Short: Remilia, Lyrica, Chen, Cirno, Rumia, Flandre.
now i plan on going through the offical print work and doing a size comparison to see if i can get some more character sizes down probably getdoremy sweet size down from her sprite for touhou 15.5 soon. as well as reisen
Doremy edit 1

https://pbs.twimg.com/media/DLc1JUMW4AAhmAS.jpgfor some reason doremy is showing up as 243cm when i do the measurements which is 7 feet which is very big i might have to wait for the game to come out that or she really is super big....i i'll double check that later.
Doremy edit 2
ok i did some fixing marisa was around 208[x in that image that was slightly enlarged so i subtracted 130 and got 78 and applied that to the 243px so doremy is around 165 cm now although this might change if she ends up being shorter then byakuren when the game comes out. but for now im leaving it at 165 cm
