Posting limits for every network

One table of what each network accepts: text limit, how it counts, images and videos, thread and first-comment support, and the daily cap 1Post applies per connected account. Network figures cite the network's own page with the date we read it; caps marked 1Post are set by 1Post.

How it works

01
The table is read from the same data the composer uses, so it matches what the composer enforces.
02
See the per-network pages for each rule with its source: platform specs and limits.
03
Copy a link to the result, or open it in the composer with 1Post and schedule it to every network.

It runs in your browser. Nothing you type or choose is uploaded, and the page works without an account. To publish what you made, start a trial and open it in the composer.

Questions

Are the daily caps the networks' limits?

They are the caps 1Post applies per connected account. Some networks publish their own ceiling, which we cite on the network's page; others publish none, and then the cap is ours.

How current is the table?

Each row cites its sources with a read date. When a network changes a rule, the table and the network's page are updated together.
