Hey there! Oxdarock here!
This is a bit of a late post here, but I’ve recently finished another size scale! This one is for Weight Gain. I call it: The BLIMP Scale!
I may not consider myself an expert when it comes to weight gain, but I’m confident enough to draw it decently. Because of a lot of different factors though, this isn’t an all encompassing size chart (mainly since it utilizes an generally even weight gain sequence). It’s pretty much a general guide and in most cases, a starting point. At the end of the day, I made it just cause. XD
Hope this helps you folks out!
