How do you see my subs on youtube?

on a computer there's also a Manage button on the Subscriptions page, it gives you the full list in one scrolling page with an unsubscribe button next to each. much quicker if you're doing a cleanout.

depends which you mean. channels you're subscribed to = Subscriptions tab, then All at the top right for the full list. your own subscribers = YouTube Studio, the count is on the dashboard and there's a Recent subscribers card with See all. it only shows people whose subscriptions are public though, so the list will always be shorter than the number.
