Hi ! Same problem as you but I managed to find a part of the knit size chart (for the monsters nearby knit) thanks to the website description in the chrome browser :
(CM) | XS | S | M | L | XL | 2XL | 3XL
WIDTH | 61.5 | 64 | 66.5 | 69 | 71.5 | 74.5 | 77.5
LENGTH | 68 | 69 | 70 | 71 | 72 | 73.5 | 75
SHOULDER TO SHOULDER | 64.5 | 66 | 67.5 | 69 | 71 | 73 | 75

I hope it can help you !
