Pinterest behaves like a visual search engine, so the pin title and description are doing SEO work. You get generous limits — but only the first words show in the grid.
A Promoted Pin's title can run to 100 characters and its description to 500, but the feed only surfaces roughly the first 40 of the title. Because Pinterest is search-driven, the title and description double as keywords — front-load the terms people actually search.
| Field | Limit | Notes |
|---|---|---|
| Pin title | 100 characters | About 40 show in the grid — front-load keywords. |
| Pin description | 500 characters | First ~50 show; full text aids Pinterest search. |
| Destination URL | No character cap | Where the pin sends clicks. |
Pin titles allow up to 100 characters, but only about the first 40 appear in the feed grid. Because Pinterest is a visual search engine, lead with the keywords people search.
Up to 500 characters. Only the first ~50 show by default, but the full text helps your pin rank in Pinterest search, so use it.
