Instagram posting rules — the cheat sheet

The limits and formats that decide whether a post lands or bounces.

Caption limit

2,200 characters — but the first 125 are what show before “more”

Hashtags

Up to 30; 3–8 well-chosen tags outperform tag walls

Images

JPEG preferred; 1080px wide; 4:5 portrait gets the most feed space

Account type

Publishing via the official API needs a Professional (Business/Creator) account

Tokens

Access is a revocable 60-day token that PostAdmin refreshes automatically

What PostAdmin does for Instagram

Hashtag intelligence

PostAdmin learns which tags have historically performed on your account and suggests them per post — plus AI discovery tags matched to your exact caption.

Per-platform captions

Keep one master caption and hand Instagram its own version — longer, hashtag-rich, line-broken the way IG rewards.

History import

Pull your existing posts with their like and comment counts, so best-time and what-works analytics start on day one.

Questions people ask

Can PostAdmin post to a personal Instagram account?

No — Instagram's official publishing API only accepts Professional (Business or Creator) accounts. Switching is free in the Instagram app settings.

Will scheduled posts get less reach?

Posts go through Instagram's own official publishing API — the same route every major scheduler uses. Instagram does not penalize API-published content.

Are my Instagram passwords stored?

Never. You authorize through Instagram's own login page; PostAdmin holds only a revocable token.

Post once. Publish everywhere.
