Range of numbers?

Question

How would one express a range of numbers regarding an action? Example: I usually study anywhere between 2 to 4 hours a day. Would the からーまで grammar structure be appropriate here? 一日に普段２から４時間までを勉強する。 This is my attempt at it, but something feels off.

Answer 1

I would double the counter if we're saying "from point A until point B": 一日に普段２時から４時までを勉強する。

For your sentence, I would say "between X and Y": 一日に普段２,４時間(ぐらい)勉強する。Patterns like this are very common when speaking
