Average Maine Coon Size
While not every Maine Coon becomes a viral giant, even the average ones are notably larger than regular house cats.
Weight
Male Maine Coons: 18–22 lbs (some reach 25–30+ lbs depending on genetics)
Female Maine Coons: 12–15 lbs
Our own boys at Aspen Maine Coons demonstrate this beautifully:
Ranchcat has the textbook heavy, muscular male build — long, broad, and thick-boned.
Carbon is a prime example of the “tall + long” Coon type with an extra-long frame and show-stopping presence.
Both fall into the upper range of the breed standard, representing the kind of size people dream of when they picture a Maine Coon.
Height
Maine Coons aren’t always the tallest cats, but they have impressive body depth and structure.
Maine Coon height: 10–16 inches
Domestic Shorthair height: 10–12 inches
Even if a Domestic Shorthair is tall, it lacks the bone mass and muscular frame of a Coon.
Length — The True Signature of the Maine Coon
This is where Maine Coons dominate.
Average Maine Coon length: 19–40 inches (nose to tail)
Domestic Shorthair length: 15–25 inches
A well-bred male like Ranchcat or Carbon often looks twice the size of a typical house cat simply because of length, tail fullness, and bone structure.
Record Holders for Length
Stewie: 48.5 inches — still the longest domestic cat ever recorded.
Ludo: 46.6 inches — another enormous Maine Coon.
Barivel: Nearly 4 feet long.
Almost every Guinness World Record for longest cat belongs to a Maine Coon — further proof of their unmatched size.

2. Strong Working Origins
Early Maine Coons were farm and ship cats, requiring strength and stamina.
3. Long Growth Timeline
Most breeds stop growing in one year.Maine Coons grow slowly until age 3–5, giving them time to develop:
heavier bones
broader chests

longer frames

exceptional length
