Pinterest Character Limits: Titles, Descriptions, Alt Text

There are two limits on every Pinterest field: the one the box will let you type, and the much shorter one a real person will actually read.

Most people writing Pinterest titles and descriptions have never seen a number for any of this. They either stuff the field full because it lets them, or they write three words because that is what shows on the pin image, and both mistakes cost clicks. The field limit and the display limit are different numbers, and confusing them is the single most common reason well-designed pins still underperform. This guide lays out every real limit, what actually shows before it truncates, and a counter tool near the bottom so you can check your own copy before you publish it.

The Full List of Pinterest Character Limits

Every text field on Pinterest has a hard maximum the interface will not let you exceed, and a separate, unofficial display maximum that determines what a person browsing the feed will actually read before the text gets cut off with an ellipsis or hidden behind a “more” link. Writers who only know the first number waste characters; writers who only know the second number leave keyword coverage on the table. You need both.

Field limits come from Pinterest’s own pin and profile builders. Practical display figures are approximate, based on standard mobile app rendering and 84Pins’ own client account observations, since exact truncation shifts slightly by device, font size, and app version.

Notice that three fields (pin description, board description, alt text) all share the same 500-character ceiling, but they behave completely differently once you hit publish. That gap between “allowed” and “seen” is the entire subject of this article, and it is why the same 500-character limit calls for three different writing strategies depending on which field it sits in.

Pin Titles: 100 Characters Allowed, 40 Actually Seen

A pin title can run up to 100 characters, but on a phone screen scrolling through a feed, roughly the first 40 characters are what a person actually reads before the title clips. That is not a suggestion, it is a rendering limit: the title box on a pin tile only has so much vertical space, and text past that space either wraps awkwardly or gets truncated with an ellipsis depending on the layout Pinterest is showing that user.

This means every pin title is really two titles stacked on top of each other. The first 40 characters need to work alone, as a complete, scannable promise, because that is the only version most people will ever see. The full 100 characters still matter for a different reason: Pinterest’s search and ranking systems read the entire field, so extra descriptive words after character 40 can still earn you a match on a related search term even though no human will scroll past them. Front-load the specific, high-intent phrase (the thing someone actually typed into Pinterest search), then use the remaining characters for supporting context rather than repeating the same keyword. Our guide on SEO titles versus clickbait titles goes deeper on the wording choice itself; this article is about the character math that constrains it.

A title like “10 Easy 30-Minute Weeknight Dinners for Busy Families Who Hate Meal Prep” is 76 characters. The first 40 characters read as “10 Easy 30-Minute Weeknight Dinners for” which is a clean, complete phrase on its own, and the remaining 36 characters keep adding search relevance without needing to be seen. That is the pattern to copy: make character 40 a natural breakpoint, not a place where a word gets sliced in half.

Pin Descriptions: The 500-Character Field vs the 55-Character Reality

The pin description field allows 500 characters, which is more than four times the length of this paragraph so far. In the feed, though, only about the first 50 to 60 characters display before the text cuts to “… more,” and most people never tap to expand it. The full description only becomes fully visible once someone clicks into the pin’s close-up view, at which point they have already decided the pin is worth a second look.

That changes what the description is for. The first sentence is doing the same job as a meta description snippet: it needs to restate the pin’s value in plain language and work as a stand-alone hook, because for most viewers it is the entire description. Everything after that first sentence is written for the close-up view and for Pinterest’s indexing, which reads the full field regardless of what displays. That is the place for related keywords, a bit more context, and a soft call to action, following the same logic covered in our guide to writing titles and descriptions on Pinterest.

Read that chart as a writing-priority guide. Fields near 100% (board titles, profile bio) can be written straight through since a reader sees the whole thing. Fields near the bottom (pin description, alt text) need their most important words at the very front, because the rest of the field is functionally invisible to a human scrolling the feed even though it still counts for search.

Rewriting titles and descriptions across an entire catalog eats hours a client rarely has: see how 84Pins handles it at scale.

Alt Text: The Limit Nobody Sees but Pinterest Reads

Alt text shares the same 500-character limit as pin and board descriptions, but it plays by completely different rules because it never appears anywhere in the Pinterest interface. No viewer, however long they stare at a pin, will ever see the alt text field. It exists for two audiences only: screen readers, which read it aloud for people using assistive technology, and Pinterest’s own systems, which use it as additional context to understand what a pin shows and where it should rank.

Because nobody sees it, alt text is the most skipped field on Pinterest, and also the easiest one to get badly wrong in the other direction, by stuffing it with unrelated keywords since “no one will notice.” Both mistakes cost you. Skipping it wastes free indexing signal your competitors are collecting; stuffing it produces a nonsensical sentence that fails a screen reader user and reads as spam to Pinterest’s ranking systems at the same time. Write alt text the way you would describe the image to someone on the phone who cannot see it: what is in the photo, what it is for, in one or two plain sentences. That single habit is one of the fastest wins in our broader image SEO work, and it is a field most DIY accounts have simply never filled in.

Board Titles, Board Descriptions, and Profile Fields

Board titles have no hard field limit as strict as the pin title, but Pinterest recommends keeping them to around 50 characters, and titles longer than that clip on the board tile itself, the small thumbnail that shows the board name to anyone browsing your profile. A board called “Small Space Living Room Ideas” is clean at 30 characters; a board called “Small Space Living Room Ideas and Inspiration for Apartments and Rentals” runs well past the point where it displays in full, so the effort is wasted on the tile even if it still helps search. This is the same logic covered in our guide to organizing boards on Pinterest: specific and short beats descriptive and long.

Board descriptions share the pin description’s 500-character limit, with roughly the first 160 characters visible before a “more” link appears underneath the board name. Treat the opening line the way you would a pin description’s opening line: state what the board is for, in language someone would actually search, then use the remaining characters for related terms.

Two profile fields round out the list. Your display name has a 65-character limit and shows in full in most placements, so there is little truncation risk there beyond keeping it recognizable as your brand. Your profile about section (often called the bio) is capped at 160 characters and shows in full on the profile page, which makes it one of the only fields on this whole list where the field limit and the display limit are the same number, so you can write it straight through without worrying about a cutoff.

Check Your Own Copy: The Character Counter

The fastest way to internalize all of the numbers above is to test your own writing against them before you hit publish, rather than guessing and finding out later that half your title got clipped. Pick the field you are writing for below, paste or type your copy, and watch where it sits against both the field limit and the practical display limit.

Two patterns show up almost every time someone runs real copy through this. First, titles that felt “complete enough” at a glance are often clipping a key word right around character 38 to 45, which a plain word count would never catch without literally counting. Second, descriptions people assumed were too short at 120 characters are actually well past the 55-character display cutoff already, meaning the extra length is pure keyword coverage for search rather than anything a scrolling viewer reads, which is exactly the trade-off worth making on purpose rather than by accident.

Character-Limit Mistakes and a Pre-Publish Checklist

The same handful of mistakes show up across almost every account we audit and rebuild, and every one of them is fixable in minutes once you know the numbers.

Burying the keyword after character 40. A title that reads “A Blog Post I Wrote About Some Great Ideas for 30-Minute Family Dinners” wastes its entire visible window on filler before the actual topic even appears.

Leaving alt text blank on every pin. It is free indexing signal and a genuine accessibility gap, and it takes fifteen seconds per pin to fill in properly once you have a habit for it.

Stuffing descriptions with repeated keywords to fill all 500 characters. Pinterest’s systems and human readers both recognize the pattern, and it reads as spam rather than as thoroughness. A tight 200-character description that says something real usually outperforms a padded 500-character one, and pairing it with real keyword research beats guessing at synonyms to fill space.

Writing board titles like blog post headlines. A board is a category, not an article; “Weeknight Dinners” beats “The Ultimate Collection of Weeknight Dinner Ideas for Every Family” because the short version displays in full and reads as a real destination rather than a stuffed folder.

Before publishing a batch of pins, run each one through this checklist:

• The most important word or phrase sits within the first 40 characters of the title.
• The first sentence of the description makes sense entirely on its own, with no dependence on the rest of the field.
• Alt text describes the image in a full plain sentence, not a keyword list.
• Board titles are short enough to display without clipping on the board tile.
• Nothing in any field is repeated more than once purely to add length.

What This Means for Your Business

1. Write for the display limit first, the field limit second. Forty characters of title and roughly fifty-five of description do the real persuading; the rest is search coverage.

2. Alt text is free and almost always skipped. Filling it in properly is one of the fastest, lowest-effort wins available on an existing account.

3. Longer is not more optimized. A field stuffed to its 500-character ceiling with repeated keywords underperforms a shorter, specific description almost every time.

4. Board names are a display problem too. A board title that clips on its own tile loses the clarity it was supposed to add to your profile.
