Dude 6’2" is not quite tall- or at least nothing to prevent you from squatting. A buddy of mine is 6’8" and could not squat for shit when he first started out, he’d basically fall over if he tried to get anywhere near parallel. When he finally put the concerted effort into trying to master the squat, he was able to do so in a couple of months and now squats below parallel with great form.
You most likely have:
-very tight hip flexors
-very tight calves
-very weak hamstrings
Stretch your hip flexors and hip rotators several times a week or even every day if you are so inclined and really work on getting your hamstrings stronger. Good mornings and RDLs will really help here. Also, Bulgarian split squats can help strengthen your legs while at the same time providing an active stretch to the hip flexors while getting you used to getting deep as possible.
And beyond all of that, one of the best things you can do is just grab a broomstrick or empty bar and practice going as deep as possible until you can consistantly get to the depth you need.
