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

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

Tumblr text is limited to 4,096 characters, counted by code points. This page lists every text, media and posting rule 1Post checks for Tumblr: counts, sizes, lengths, threads and the daily cap. Where Tumblr publishes a figure on its own page we cite it with the date we read it.

## What 1Post checks for Tumblr

| Rule | What 1Post checks |
| --- | --- |
| Text limit | 4,096 characters, counted by code points |
| Media accepted | Images, GIFs, Video |
| Images per post | 30 |
| Videos per post | 1 |
| Threads | Yes, as a chain of replies |
| First comment | No |
| 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.

## What Tumblr publishes

## Questions

**How is Tumblr text counted?**

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

**Where do these Tumblr 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.
