Some male adults may actually exceed this and could range up to 6 feet in length. Females are typically larger than males, which can help you distinguish between the sex of the snake. But obviously this is not always accurate.
How big do corn snakes get you ask. Well, this can vary with every snakes. And there seems to be a big debate online about which species is bigger, male or female. Unlike most animals, male corn snakes will commonly be smaller than the female species. This is because snakes live by themselves, rarely in a couple. So they have no means for defending territory or fending off any competing males, as they don’t commonly express typical male behaviours. However, of course, this isn’t always the case and male are sometimes bigger than the females.

How Big Can Adult Corn Snakes Get?

An adult corn snakes usually weighs around 900 grams and can take up to 2 years to reach this weight, with a diameter of roughly 2.5cm. So a corn snake is a very slender species.
New born corn snakes will be no longer than a foot long, and will commonly take about 2 years to reach their full growth and length. Please remember, that as your corn snake grows, so should the size of their enclosure. The size of a corn snakes enclosure can have an affect on their natural growth if too small.

Enclosure/ Vivarium Size Relation
Obviously the bigger the enclosure, the better, so please assess your living space before purchasing a corn snake. If you look at the enclosure and think that it looks too small for the size of your snake, then it most probably is. At a very minimum, the smallest tank for a corn snake is 20 gallons. For example a 40 gallon tank would give your adult corn snake a much happier life, which more space for it to roam around freely. The happiness of a corn snake should be at the forefront of every owners mind.
A 36” x 18” x 17” enclosure would be an ideal size for your adult corn snake. This would give the snake twice as much room as the recommended minimum and has the space to incorporate come branches for your snake to climb up and along.
The size of cage has no limit really. However the problems come when trying to keep the enclosure clean, and at a suitable temperature for your corn snake. Monitoring temperature can then become a struggle as the enclosure needs to sty at a constant. You also don’t want an enclosure that will take all day to properly clean out. No one realistically has that much time on their hands, or the patients .So more than likely it will be rushed, and not up to the standard that it should be.
How Fast Do Corn Snakes Grow?

This is due to the snake commonly being more active, and therefore eating more, in turn, growing also. The colder months through winter your corn snake may not be as active and will likely not grow at the pace it does through the warmer months.

How Long Do Corn Snakes Live In Captivity
Corn snakes can live for many years in captivity, usually between 15-20, although there are many differences between their natural environment and what the environment they would have in captivity is like.
