Social media data from 1Post
Five tables built from the same data the 1Post composer uses: text limits, how each network counts characters, media rules, daily posting caps and X API prices. Each cites the network's own page where we read one, with the date, and is free to quote with a link back.
Tables
Social media posting limits by network
Text limits, counting rules and daily posting caps for every network 1Post publishes to, in one table, with sources and read dates.
How each network counts characters
The counting rule behind each network's text limit: X weights links and emoji, Bluesky counts what a reader sees, Threads counts emoji bytes.
Image and video rules by network
Images and videos per post, formats, sizes, shapes and video lengths 1Post checks for every network, with what Threads and Instagram publish.
Daily posting caps by network
How many posts a day 1Post publishes per connected account on each network, beside the ceilings Instagram, TikTok, Tumblr and X publish.
X API prices and posting limits
What X charges to create a post through its API, with and without a link, and the limits on creating posts, from X's own pages.
From one post to every feed
Plan the week in one sitting, keep your team in the loop, and let 1Post publish on time while you get on with the rest of your day.
