What size enclosures should I get??

You're welcome! Glad the dimensions work out for you. I'm jealous of all y'all that have a dedicated snake rooms... maybe at my next place.

If your boa's a standard BI I'd anticipate her finishing up around around seven or eight feet. Three feet at two years old seems kinda small for a standard BI, though -- a standard BI fed on the typical 7-10 day regimen can approach four feet by the end of their first year. Either your girl was slow-grown by her previous owner (a good thing!), has more Central American influence in her background, or is actually a yearling. Make of that what you will.

Side note: if you'll be keeping your boa and your royals in the same room, I'd highly recommend having a boid panel and/or IBD test run on your boa. IBD can quickly wipe out a python collection if you're not careful. It's more of a problem on the morph-y to standard boa side of the market, where your girl likely came from. At the very least, a test should be able to give you peace of mind that your girl's healthy.

Snake room = 3 bedroom house, need a room for me, one for my daughter, and with a bunch of snakes no one visits so they get the 3rd bedroom
I've actually been ask how can I sleep in a house with snakes in it

I feed Cheyenne (the Boa) every 2 weeks and she gets a Rat 60g+

I'm guessing the IBD test is a blood test? (did some reading). When she was in for her check up, they check, eyes, mouth, heartbeat, mite test, and with her they had me bring in a stool/urate sample to test, But no blood test were done

Here's an older pic of Cheyenne
