Pinterest Pin size, video specs and text limits (2026)

Pinterest spreads its Pin numbers over a few pages: one for regular Pins, one for ads that also covers regular Pins, and developer docs for apps like schedulers. This guide puts them together as checked in October 2026, says where each number comes from, and points out the few places where Pinterest's own pages don't agree.

Sizes are width x height in pixels. "In the Pinterest app" means what you can do by hand on pinterest.com or in the mobile app. "From a scheduling app" means what Pinterest's API accepts, which is what every scheduler has to follow.

Pinterest Pin size at a glance

The text limits are the same for both kinds of Pin:

The best image size for a Pin: 1,000 × 1,500

Pinterest's Pin specs page doesn't name a shape for image Pins. The shape comes from its specs page for standard Pins and ads, which says the standard image format works for ads and for regular Pins from business accounts. It recommends 2:3, or 1,000 × 1,500 pixels, and warns that Pins taller than 2:3 might get cut off in people's feeds. So 1,000 × 1,500 is the size to aim for, and a taller canvas risks losing the top or bottom.

Some file details to know:

• File types: BMP, JPEG, PNG, TIFF and WebP.
• File size: up to 20 MB on the web. For the mobile app, Pinterest's two spec pages disagree: the Pin specs page says 1 GB recommended and the ad specs page says 32 MB. Keep photos under 20 MB and they work everywhere.
• Color: Pinterest converts every upload to a standard 8-bit RGB JPEG and doesn't support custom color profiles, so colors can shift slightly. Its ad specs suggest uploading PNGs in sRGB to avoid losing quality.
• Backgrounds: a white or near-white background gets a faint dark layer (black at 4% opacity) in light mode, and a black or near-black one gets a faint white layer (10%) in dark mode. Pinterest adds these to separate Pins from the app background. They don't apply to videos.

If you're cropping one photo for several networks, see social media image sizes, or check a file against every network at once with the free size checker. The file stays on your device. The free image resizer makes a 1,000 × 1,500 Pin, and the other networks' sizes, from one photo.

Video Pin size, length and file type

Pinterest's Pin specs page recommends a 9:16 ratio, or 1080 × 1920 pixels, for full-bleed video, meaning video that fills the whole screen. It also accepts 1:2, 2:3, 3:4, 4:5 and 1:1.

• Length: at least 4 seconds and at most 5 minutes.
• Encoding: H.264 or H.265.
• File types: MP4 or M4V on the web, and MP4, MOV or M4V in the Pinterest app.
• File size: the Pin specs page lists no maximum for video Pins.

The ad specs page lists a longer range for standard video: 4 seconds to 15 minutes and up to 2 GB. That page is written for ads, even though it says the format can also get organic impressions. The Pin specs page is the one for regular Pins, so we'd keep videos to 5 minutes.

The Pin specs page also lists safe-zone margins for text and key elements, the same for image and video Pins: 270 pixels at the top, 65 on the left, 195 on the right and 790 at the bottom. It doesn't say which canvas size they're measured on or show them in a picture, so treat them as a guide and check the preview before you post.

Video covers

In the Pinterest app, choose Edit cover to pick a frame as the thumbnail for a video Pin. From a scheduling app, a video Pin needs a cover image sent with it: Pinterest's developer guide says a valid image has to be provided or the request is rejected. After creation, Pinterest may take a few seconds to process the video.

Titles, descriptions, alt text and links

• Title: up to 100 characters. Depending on the device, about the first 40 may show in feeds, and only the first 30 in Chinese, Japanese, Korean, Arabic and other double-byte languages. Put the key words first. The free post preview marks where a long title is cut.
• Description: up to 800 characters. It doesn't show when someone views the Pin in the home or search feed, but Pinterest's algorithm uses it to judge who should see the Pin, so Pinterest recommends writing one.
• Alt text: up to 500 characters, for standard Pins and video Pins. It's read aloud only to people using a screen reader.
• Link: the page people reach when they click the Pin. The API reference allows up to 2,048 characters. Pinterest's help center says it doesn't allow certain redirects or URL shorteners, so link straight to the page. You can only edit links on Pins you created.

Pinterest's help pages and its developer reference agree on the title, description and alt text limits, so there is no app versus API difference there. That includes the 800-character description, which is the limit Unisenda's counter uses. For how other networks count, see social media character limits.

What scheduling apps can send

Most of the rules match, but a few details differ between the Pinterest app and its API:

Pinterest's own scheduling option is for business accounts and reaches up to 30 days ahead. A scheduling app holds the Pin and posts it at the time you choose.

How to schedule Pins in Unisenda

Unisenda posts image and video Pins to the board you choose. To schedule one:

1. Open Connections, choose Connect for Pinterest, and approve access on Pinterest's own screen.
2. Click Create post and add one image or one video from the Media library. Each Pin holds one image or one video, so Unisenda doesn't post Pinterest carousels.
3. Select your Pinterest account and open its tab. Choose the board, then add a title, description, link and alt text. For a video, choose Cover to pick a frame or upload an image.
4. Check the preview and the character counter (800 for the description).
5. Pick a date and time in Schedule for and click Schedule, or click Post now or Save draft.

Some details that help:

• Photos: upload JPG, PNG or WebP files of up to 20 MB. Unisenda sends Pinterest a JPEG under Pinterest's 20 MB limit. iPhone HEIC photos need to be exported as JPEG first, and GIFs can't be published.
• Shape: use Edit to crop the photo to the shape you want. Your original never changes.
• Videos: upload MP4, MOV or WebM files of up to 500 MB. Videos that aren't H.264 MP4 (phone videos in MOV or HEVC, or WebM) get an H.264 MP4 copy automatically, and your original stays in your library.
• Checks: Unisenda flags what a network would reject before you schedule, so you can fix it first.

Posting the same photo to other networks too? The post to all social media at once guide shows how to give each network its own version. You can try the composer with sample accounts in the demo, where nothing is ever published. Plans and the 7-day free trial are on the pricing page.
