Why creators use this
600-1000 characters with deliberate line breaks, so the caption keeps its structure instead of collapsing into one block on paste.
8-12 hashtags on their own line, deliberately mixed between high- and low-volume so you're not only competing in tags with tens of millions of posts.
Opens on a hook line, because Instagram cuts the caption at roughly 125 characters in the feed and the rest sits behind “more”.

FAQ
How long should an Instagram caption be?+
600-1000 characters works well for value-led posts. Instagram truncates at about 125 characters in-feed, so the hook has to do its work before the “...more” cut.
How many hashtags should I use on Instagram?+
Eight to twelve, at mixed volume. Instagram has publicly said relevance matters more than quantity, and a block of 30 broad tags mostly signals automation.
Why put hashtags on a separate line?+
Readability. Inline tags break the flow of the sentence they're sitting in; on their own line at the end they stay functional without interrupting the copy.
Does this work for Reels captions too?+
Yes, though Reels captions generally perform better shorter — take the hook and the first block, and drop the rest.
