Changing size from Medium to anything else

[nuncle]

Greetings, Folks!
Hopefully this is a question with a simple answer and I'm just an idiot for missing it
When designing a character, how do you change his size listing? On the Abilities tab it shows the listing for Medium. But even if I change his size under the Personal tab, his Medium size doesn't change. I tried increasing his size to over 20 feet tall and he's still listed as "Medium"
Any clues about how to update that listing? Also, I was creating a NPC, in case the settings for those make a difference. Thanks tons in advance, Smart Ones!

Try adding growth and that should change it to the size you want.

Ah ha! I think my first statement is the true one in this case. Simple and idiot
Thanks much!

NP herolab takes some getting use to plus you need to look at the core rules to find the right level of growth you need for 20 feet. In 2E i think its like 8 or 9, not sure about 3E as im still learning how it works for that power.

They play a bit loose with Size/Growth and specific heights in 3e. Medium size is rank -2 Distance of height on the Ranks and Measures table, which is "up to 6 feet." 4 ranks of Growth adds +1 Size to Large, which makes you rank -1 Distance of height, or "up to 15 feet." 8 ranks would be Huge, rank 0 height at "up to 30 feet."

I put all of those in quotes because there's really no formal rule for heights or ranks in between, so for 20 feet you're technically in the Huge range, but it's up to you whether that means your PC has the full 8 ranks of Growth or maybe only 6 ranks to reach 20 feet or something.

The specific height and weights in the Personal Tab are all for flavour and aren't really connected to any of the other parts of the rules mechanics like size.
