A Pinterest Pin title is 100 characters and the description shown on organic Pins is 500. Video Pins run from 4 seconds to 15 minutes. The number Pinterest does not publish is how many Pins you can create per day, which is the one people searching for “Pinterest limits” usually want.
Pinterest media limits
These come from Pinterest’s own creative specifications. Note that the specs page covers ad creative, so a few figures (notably the 800-character description) apply to the ads surface rather than to an ordinary Pin description.
| Limit | Value |
|---|---|
| Video duration | 4 seconds to 15 minutes |
| Recommended video length for ads | 6 to 15 seconds |
| Video file size | Up to 2 GB |
| Video formats | MP4, MOV, M4V (H.264 or H.265) |
| Image file size | 20 MB desktop, 32 MB in app |
| Image formats | PNG or JPEG, converted to 8-bit RGB JPEG |
| Recommended image ratio | 2:3 |
| Carousel images | 2 to 5, up to 10 for a sales objective |
| Title | 100 characters, roughly the first 40 display |
| Ads description field | Up to 800 characters, used algorithmically rather than displayed |
Note: Figures here were verified against Pinterest’s product specifications page in the Pinterest Business help centre as of September 2026. Platforms change these without notice.
The display truncation is worth more attention than the cap. Pinterest shows roughly the first 40 characters of a title in feeds, and only 30 for double-byte languages, so a title written to fill 100 characters is mostly invisible.
For the organic Pin description and board field limits, see Pinterest character limit and the Pinterest character counter.

Daily pinning limits: what Pinterest actually says
Pinterest confirms that accounts have limits on how many Pins they can save and create, and that hitting them results in a temporary restriction. It does not publish the thresholds.
Community figures for daily Pin creation circulate widely and are usually quoted as a round number in the low hundreds to low thousands. They are unofficial and unverified. The behaviour they describe is real: Pinterest does throttle heavy pinning, and it is one of the platforms most sensitive to repetitive saving of the same link. The number attached to it is not something Pinterest has ever confirmed.
The signals that appear to matter:
- Account age and standing. New accounts are throttled hardest, which is the standard pattern.
- Repetition. Saving the same URL to many boards in a short window is treated as spam behaviour more readily on Pinterest than on most platforms.
- Domain reputation. Pinterest maintains a view of the sites Pins point to, and a flagged domain limits the Pins that reference it regardless of the account saving them.
- Speed. Bursts of saves in seconds are the fastest route to a temporary block.
Pinterest’s guidance to publishers has long favoured a steady daily rhythm over batching, and that advice reads better as a description of the throttling than as engagement folklore.
The API side
Pinterest’s v5 API requires a business account for content creation, and access to the API is granted per app rather than being open by default. That gating, rather than a published per-day cap, is the practical constraint on automated pinning. We could not retrieve Pinterest’s developer rate limit tables in this session (the developer docs blocked automated fetching), so we are not going to state per-endpoint numbers we could not read.
The short version
- Pin title 100 characters, though roughly 40 display. Description 500.
- Video 4 seconds to 15 minutes, up to 2 GB.
- Images up to 20 MB on desktop, 32 MB in app, 2:3 recommended.
- Carousels 2 to 5 images, up to 10 for sales campaigns.
- Daily Pin creation limits exist, are enforced, and are not published. Repetition of the same link matters more than raw volume.
Scheduling Pins at a steady pace
BulkPublish schedules Pins through Pinterest’s official API, which means the account has to be a business account and the same platform rules apply. The more useful part for Pinterest specifically is spreading a batch out: queueing 200 Pins to go out over a month at a set daily rate is both closer to Pinterest’s own advice and much less likely to trip a temporary restriction than saving them all in an afternoon.
Repeat posts handles the other Pinterest habit, which is re-sharing evergreen Pins on a schedule rather than manually.
