Why 165 cm and not 160?

Because a threshold copied from a cis-female catalogue left the page nearly empty. Trans performers run taller on average, so the line sits where this roster actually splits.

Is petite the same as small build?

Here it means height and only height. Cup size, weight and build are separate filters in the sidebar, and they move together less than the word suggests.

Why are some obviously short performers not on this page?

Because no source states their height. Anyone without a recorded figure stays off the page rather than getting an estimate.

Petite trans pornstars (94)

Under 165 cm, from height fields on outside profiles. The cut-off is higher than a cis-female database would use and that is deliberate: trans rosters skew tall, and a 160 cm line left the page nearly empty when the threshold was set.

Who you get: Brittney Kade, Emma Rose and Khloe Kay on the American side with the deepest catalogues here, Leilani Li at 152 cm as the shortest of the names with a real filmography, Celeste Fuentes working since the early 2000s, and Kimberlee, one of the few post-op performers indexed anywhere on the site. The Latina end of the page runs Yasmin Dornelles out of Sao Paulo and Vanessa Jhons, who is Venezuelan and works out of Spain. It is a mixed page by nationality and by era, which the taller categories are not.

One pattern shows up in the scenes: those with a cis woman in them are a larger share here than on most pages, while everything else sits near the American average. Whether that is a casting habit or coincidence on a small group, we would not claim to know.
