Pin titles take 100 characters and descriptions 800. Descriptions do not show in the home feed, so put your keywords in the title too. Paste a description below to count it.

## The short answer: Titles: 100 characters. Descriptions: 800. Bio: 500.

A Pin title holds 100 characters, and Pinterest says the first 40 are the most likely to show. The description holds 800 characters, in the app and through the API. It does not appear in the home feed or search feed, but Pinterest says "Descriptions are used by our algorithm to determine relevance for delivery."

Your profile bio takes up to 500 characters and your username 3 to 30. Through the API, alt text takes 500 characters and a link 2,048. In the app you can also tag up to 10 related topics on a Pin.

- **Pin title**: 100 (About the first 40 show)
- **Description**: 800 (Not shown in the feed)
- **Bio**: 500 (Username: 3 to 30)

## Count a Pin description against Pinterest's 800 characters

- Description: up to 800 characters.
- Hashtags: no fixed limit.

## Every Pinterest text limit in one table. With where each number comes from.

| Field | Limit | Source |
|---|---|---|
| Pin title | 100 characters | Pinterest Help Center and API |
| Title shown first | About 40 characters | Pinterest's ad best practices |
| Pin description | 800 characters | Pinterest Help Center and API |
| Text box on the Pin | 250 characters | Pinterest Help Center |
| Alt text | 500 characters via the API | Pinterest API; no app limit found |
| Destination link | 2,048 characters | Pinterest API |
| Tagged topics | 10 per Pin | Pinterest Help Center |
| @mention stickers | 5 per Pin | Pinterest Help Center |
| Question sticker | 70 characters | Pinterest Help Center |
| Bio | 500 characters | Pinterest Help Center |
| Username | 3 to 30 characters | Pinterest Help Center |
| Name | Not published | The Help Center states no limit |
| Board name and description | Not published | The Help Center states no limit |
| Boards per account | 2,000 | Pinterest developer docs |

Checked on October 17, 2026. "Not published" means Pinterest states no number. Pinterest's ad best-practices page still lists 500 characters for descriptions; its Pin specs and API say 800.

## What the app allows, and what a scheduled Pin can carry. Schedulers publish through Pinterest's API.

| Field | Pinterest app | Schedulers (the API) |
|---|---|---|
| Title | 100 characters | 100 characters |
| Description | 800 characters | 800 characters |
| Alt text | Not published | 500 characters |
| Destination link | Not published | 2,048 characters |
| Tagged topics | Up to 10 | No field for them |
| Text box on the Pin | 250 characters | No field for it |

Every scheduler, OmniSocials included, publishes through Pinterest's API (version 5.28.0, read on October 17, 2026). Tagged topics and on-Pin text are added in the Pinterest app.

## Write Pins that get found. The title shows, the description ranks.

1. **Put the keyword early in the title** Pinterest says the first 40 characters are the most likely to show. In Tailwind's 2024 data, about 80% of the most viral Pins had a target keyword in the title.
2. **Always write a description** It does not show in the feed, but Pinterest uses it "to determine relevance for delivery". Describe what the Pin shows and where it leads.
3. **Shorter descriptions are fine** The most viral Pins in Tailwind's study averaged 220 to 232 characters. You do not need all 800.
4. **Add alt text** Pins with alt text earned 25% more impressions in Tailwind's data, though Tailwind could not confirm the cause. Through the API, alt text takes 500 characters.
5. **Use the bio for keywords** 500 characters is room for who you are, what people will find on your boards and the words they search for.
6. **Tag topics in the app** You can add up to 10 related topics to a Pin. The API has no field for them, so add them in the Pinterest app if you want them.

## Sources and method

Each limit comes from Pinterest's Help Center, its ad best practices or its API reference (version 5.28.0), read on October 17, 2026. Where Pinterest publishes no number, the table says "Not published" instead of repeating a figure from another guide. Pinterest's own pages disagree on the description limit (800 in the Pin specs and API, 500 on the ad best-practices page), so the page uses 800 and notes the other. Tailwind's figures are vendor data.
