How to calculate final height

I was wondering where I could go to get an X-ray to estimate my final height, and if I actually need a doctor's referral for that kind of thing.

For context, I'm 17 years old and currently 5'4".
My dad is about 6'0" and my mom is 5'5".
I take after my father, and he was a late bloomer—he didn't really hit his stride until his junior or senior year of high school.
Since I'm finishing up my junior year and most of my physical development seems pretty standard (my beard is just starting to come in, though it isn't full yet), I'm curious if there's still a chance for me to gain a few more inches.
I actually have an X-ray of my wrist, and you can see a tiny gap—maybe 1 or 2 mm—in the area where the bone grows (I think it's called the epiphyseal plate). This suggests my growth plates haven't fully closed, but I have no idea what size that gap needs to be to guarantee I'll still grow.

It’s not like this is the most important thing in the world to me; I’m mostly just asking out of curiosity.

Thanks so much!

As far as I am aware, a hand X-ray is the only way to determine if someone still has growth potential. You might still grow according to those results, though nobody can predict how much.
There is growth hormone therapy, but it is only effective before bone maturation is complete—which, in your case, is cutting it close—and the cost is astronomical.

I understand where you're coming from...
I'm not interested in hormone therapy at all; it feels like I'd be forcing my body into something it isn't ready for, and given my height, those treatments wouldn't really serve my purposes anyway.

My main focus right now is just finding out how to estimate my potential final height. I've heard it's possible to get an accurate reading through X-rays of certain bone areas.

If anyone knows of a clinic or a specialist that offers this kind of assessment, I would truly appreciate the help!
