I say around 5'0

She's shorter, but I don't know the height.

How do you know she's shorter?

How about who cares!

That, and no one has even said.

Well those two reasons for starters, but I believe Misty is 5'0 and she is taller than Ash who is taller than May. Although Ash and Misty may be the same height now, but they are still taller than May anyway. Plus Brock has a good two feet over her and he's not 7'0. Like I said the first two reasons are good enough.

Misty seems like 5'2

She is also just 10 or 11, so she would be around 4'

Exactly.

Naah most  10-11 people are around 4'10 or 4'11

No they're not, I remember when I was 10, most people were around 4', usually withing 6 inches
