Weight and Height

Each different Pokémon species and their forms can vary in weight and height. The Pokémon entry in the Pokédex records the standard weight in kilograms (kg) and height in meters (m).

Based on the standard values, the acquired Pokémon can be labeled:
 * XXS half of standard height/weight
 * XS 0.75 times the standard height/weight
 * XL 1.25 times the standard height/weight
 * XXL 1.5 times the standard height/weight

XXS and XXL
XXS and XXL Pokémon were released in December 2022. The following Pokémon can appear in these sizes:
 * Poochyena
 * Mightyena
 * Mawile

When Trainer encounter an XXS or XXL Pokémon, they have a different glow, and the size is reflected on encounter screen.

Pokédex records
Once the Trainer catch at least three of any one Pokémon, their Pokédex starts to showcase the records for the largest, smallest, heaviest, and lightest specimens them have caught. Trainers who catch XXS or XXL Pokémon or find smaller XS- or XL-sized Pokémon than they caught previously can enjoy a new celebratory message when they break their record. Trainers need to catch at least three of any particular Pokémon to set a record for that Pokémon.
