Pinterest limitations
Every pin needs a board and an image, with tight text limits. Pinterest's analytics are rich for engagement but arrive with processing delay.
Publishing limits
The limits Pinterest applies to posts published through its official API. Posty checks every one of these while you compose.
| Limit | Value |
|---|---|
| Title | 100 characters |
| Description | 800 characters |
| Image | JPEG or PNG, up to 20.0 MB Pinterest recommends 2:3 ratio - taller images may be cropped in feeds (not rejected). |
| Images per pinPosty | 1 image Pinterest also supports 2–5 image carousels and video pins; Posty publishes single-image pins today. |
| Board | required for every pin |
Rows marked Posty are current Posty product choices rather than hard platform rules.
Analytics
Impressions, saves, pin clicks, outbound clicks, reactions and comments per pin, plus pin-driven profile visits and follows.
- Pinterest analytics settle over ~48 hours; recent days are provisional.
- Audience demographics require a Pinterest ad account.
- Analytics history is limited to a rolling 90-day query window.
Inbox & messaging
Pinterest provides no comment or DM access to third-party tools.
Good to know
- No native scheduling - Posty's scheduler publishes at the chosen time.
These limits apply to every tool
They come from Pinterest's official API, so no scheduler can exceed them. Posty validates against every limit on this page while you compose - if your post passes, Pinterest will accept it.
