# Instagram specs and limits: text, media, daily cap

Every text, media and posting rule 1Post checks for Instagram, with the network's own page cited and the date read where we read one.

Instagram text is limited to 2,200 characters, counted by code points. This page lists every text, media and posting rule 1Post checks for Instagram: counts, sizes, lengths, threads and the daily cap. Where Instagram publishes a figure on its own page we cite it with the date we read it.

## What 1Post checks for Instagram

| Rule | What 1Post checks |
| --- | --- |
| Text limit | 2,200 characters, counted by code points |
| Media accepted | Images, Video |
| Images per post | 10 |
| Videos per post | 10 |
| Image formats | JPEG; PNG, WEBP are converted to JPEG |
| Image shape | 4:5 to 1.91:1 |
| Carousel | 2 to 10 items |
| Threads | No |
| First comment | Yes, up to 2,200 characters |
| Posts per day, per connected account (1Post) | 50 |

These are the limits 1Post applies in the composer, so a post that passes is not refused for them when it is sent. A network can still refuse a post for reasons outside these rules, such as its content policies.

## Questions

**How is Instagram text counted?**

Instagram text is counted by code points. The [character counter](https://get1post.com/tools/character-counter.md) applies the same rule.

**Where do these Instagram limits come from?**

They are the limits 1Post checks before a post is sent. Figures the network publishes on its own page are cited above with the date read; the rest are checks 1Post sets.

**How often is this page updated?**

When a network changes a rule or we read a newer figure, the page changes with it. The date at the top shows the last change.
