I think Robert just kick started the idea that we start submitting big pitcher dimensions. Unfortunately we all greed that we need to be specific in the measurement or what we call "big".
So ideally we can do as what Robert did.
1. Measure height and width.
2. Measure how much water it can hold
3. Take a photo with references for size
Maybe we can also agree to distinguishing between pitchers in the wild and pitchers cultivated. Also maybe a contest, who cultivated the largest pitchers of each species?
We can subumit to the guiness book of world record
