This doesn't include Alolan forms or Mega Evolutions.

What about Pumpkaboo/Gourgeist and alternate forms? I would assume that you would want alternate forms to be treated like any other Pokemon, but Pumpkaboo's/Gourgeist's other forms change both the height and weight, despite it looking the same.
With Pumpkaboo and Gourgeist it would only be their average height and weight  and as for other Pokemon I was only asking for the Pokemon in their original form. So in other words no cosplay Pikachus or Castform affected by the weather.

This might help you: Sizedex.

Your question was answered in this post: Click here.

I calculate the average height to be 4'1", the average weight to be 149.3 lbs.

This doesn't answer the question, as the sizedex doesn't show the average weight and height of all Pokemon put together. Also, the question you linked was slightly different, as it asked for the average weight and height of all Pokemon and their alternate forms, AND was asked a day after this question.
I edited this slightly so the answer is there in this post, hope you don't mind.
actually this answer is straight from the other answer which includes alternate forms and megas so this answer isn't correct
