On average, the Maine Coon cat is larger than almost all other domestic cats, with the exception of the F1, or first filial, Savannah cat. The F1 Savannah cat is the largest among domestic cats, although it is not recognized as a formal breed. The Maine Coon is the largest domesticated cat breed, but this statement requires clarification.

Comparing the size of the F1 Savannah cat with the large Maine Coon can be misleading, as the Maine Coon depicted below is unusually large for its breed. Conversely, the F1 Savannah cat named Titan above represents a typical size for its breed and filial. This comparison highlights the challenges in assessing the sizes of domestic cats. In this instance, the Savannah cat is smaller than the Maine Coon.

There are many conditions to the claim that the Maine Coon is the largest domestic cat breed. For instance, a small female Maine Coon may be smaller than a large male Ragdoll cat. Similarly, a small female Maine Coon could be outmatched in size by a large male Norwegian Forest cat.
Moreover, some F2 Bengal cats can surpass many Maine Coons in size. The internet often misrepresents the size of Maine Coon cats, focusing on exceptionally large males. At cat shows, the Maine Coons on display are typically of more average size, unlike the oversized examples sometimes seen online from Russia. These are social media stars but not cats competing at cat shows.
However, it’s crucial to note that Maine Coons are generally among the largest of all cat breeds. I’ve discussed this on a page I wrote years ago, which you can visit by following this link. Comparing the smallest female Maine Coons to the largest males, the latter may be twice the size or even larger.
The Ragdoll breed is also quite large, not far behind the Maine Coon in size. The Siberian cat is another large breed, comparable in size to the Ragdoll. F5 Bengal cats are about the size of a standard random-bred, or moggy, cat, while the first filial Bengals are larger, though not as large as the first filial Savannah cats.
Male first filial Savannah cats, due to their size and resemblance to their wild ancestor, the serval, are sometimes mistaken for medium-sized wild cats. This confusion is sometimes echoed in the media, mistaking an escaped serval for a first filial Savannah cat, as they appear quite similar.
These glamorous and exotic domestic cats are wonderful status symbols but very few people are in a position in their life in terms of time, facilities and funding to take care of them to the proper standard.
