Maine coon 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 Maine coon gets is the weight above — 10–24 lb — and nothing more precise than that.
Common questions
How much does a full-grown Maine coon weigh?
A Maine coon weighs 10–24 lb (4.5–11 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 a range instead of one weight?
Because the source publishes a range. Weight varies within any breed with sex, genetics and health, and a mixed-breed cat usually falls between its parents' breeds. Narrowing 10–24 lb down to a single number would look more precise while being less true.
Does this page say what size class the Maine coon 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.
