I'd like to take this moment to mention that using Pokemon Lets Go and Eevee's metric for pokemon sizes. A pokemon can vary in height and weight.
Height can deviate at about 40% of the average for the Pokemon
Weight can deviate at about 60% of the average for the pokemon.
A Gardevoir for example at their tallest could be 7'3" and weight at their maximum 77.4 KG or 170 lbs using this metric.
