Thai Size
There is no size class on this page, and that is deliberate. Dog breeds have a widely used small/medium/large/giant convention; we found no equivalent published classification for cats. So the honest answer to how big a Thai gets is the weight above — around 11 lb — and nothing more precise than that.
Common questions
How much does a full-grown Thai weigh?
A Thai weighs about 11 lb (5 kg) as an adult. That is the mass Wikidata publishes for the breed under a CC0 license, re-checked here every week.
Why is there one weight instead of a range?
Because that is what the source publishes for this breed — a single adult mass, not a span. Real Thais still vary with sex, genetics and health, so read about 11 lb as the middle of a spread this source does not put numbers on. We don't invent the edges.
Does this page say what size class the Thai is?
No, and that is deliberate. Dog breeds have a widely used small/medium/large/giant convention; we found no equivalent published classification for cats. Rather than invent one, this page gives the weight and stops there.

Weight varies within the Thai by sex, genetics and health, and mixed-breed cats fall between their parents. This is a typical range, not a guarantee.
