Would a male ball python reach 5 feet

[Regius_049]

My 4 years and 10 months old male ball python is currently 4 feet long or almost 4 feet long. Would he reach 5 feet in the future or he will continue to grow in girth only? I,m asking because i just built for him a new enclosure, size in feet: 2 long, 2,62 deep, 3,30 high. I am wondering if this enclosure size would be enough for him forever or i will have to upgrade in the future?

You should tilt it on it's side. The 3.3 ft in length would do your snake more good considering you'd still have 2' high.
