Size Distribution

How Size Works

The size distribution of wild Pokémon is best represented as a bell curve, with the scale of 1 in the middle as the most common value.

Realistically, you're more likely to end up with something in the range of 0.9–1.1, favouring values closer to 1. The peak is less of a point and more of a plateau.

The further away you get from the centre "1", the less common the size will appear. The extremes (0.5 and 2) have approximately a 1/1,000,000 rate.

Normal Size Distribution

Standard bell curve — sizes near 1.0 are the most common, extreme sizes (0.5 or 2.0) are extremely rare.

Easy Random Size Fragment Event

The Size Fragment event expands the range of common sizes, allowing rarer sizes to be found more easily compared to regular rates. The curve flattens, making unusual sizes more accessible.
