Pinterest Video Ad Specs Guide: Sizes, Length, and Setup

If you are prepping creative for Pinterest, getting the specs right before you upload saves you a round of re-exports and a rejected ad review. This Pinterest video ad specs guide walks through aspect ratios, length, file basics, safe zones, and sound design, so you can brief or build a video pin that looks right in feed and in the ad manager.

Pinterest Video Ad Specs at a Glance

Pinterest is a visual discovery platform, and its ad specs reflect that: the feed is mostly vertical and square cards scrolling in a grid, not a horizontal timeline. A solid Pinterest video ad specs guide starts with three things you need to lock down before anything else — aspect ratio, length, and file format — because getting any one of these wrong means a reshoot or re-render, not just a tweak.

At a high level, Pinterest ads commonly support:

• Square video (1:1) for a balanced card that works across most placements
• Vertical video (2:3) for maximum feed real estate on mobile
• Standard widescreen video (16:9) mainly for repurposed content, not recommended as your primary format
• MP4 or MOV as the common file types, encoded with standard web-friendly codecs
• Video pins that can run from a few seconds up to a few minutes, though shorter cuts generally perform better for ads

Treat the numbers above as a starting point, not gospel. Pinterest periodically refines its specs page, so before you export a final batch of ads, open the current specs in Pinterest's own ad manager and double check aspect ratio, maximum file size, and length limits for the exact placement you are buying.

Aspect Ratios: Which One to Pick and Why

Pinterest's grid is built around vertical and square cards, so horizontal 16:9 video tends to get cropped, letterboxed, or simply underperform because it occupies less visual space in feed. If you are building new creative specifically for Pinterest, default to vertical or square and save widescreen for repurposing content you already have.

A practical workflow for teams running ads across several platforms: build your master edit vertical first, then export square and widescreen versions from the same project rather than starting over for each. If you are already juggling specs for other channels, our Instagram Story Ad Size and Format Guide covers the same logic for Stories and Reels placements, and the two guides pair well if Pinterest is one of several platforms in your media plan.

Video Length, File Size, and Format Basics

Pinterest allows video pins to run fairly long, but ad performance usually rewards brevity. As a rule of thumb to test, keep your core message complete within the first 15 seconds, and consider a 15 to 30 second total runtime as a strong starting point for paid placements. Longer videos can work for storytelling or tutorial-style pins, but for direct-response e-commerce ads, shorter tends to hold attention better in a scrolling grid.

On format basics:

• Export as MP4 with a standard codec rather than an unusual container format, since this reduces the chance of a processing error on upload.
• Keep frame rate consistent and avoid mixing frame rates within the same project; 30 fps is a safe, widely supported default.
• Compress for web delivery so your file size stays reasonable without visibly degrading quality — test the compressed version on a phone screen before finalizing.
• Avoid embedded subtitles burned at the very edge of the frame; leave margin so captions survive any platform-side cropping.

If you manage exports across several ad platforms at once, it helps to keep one reference sheet of settings per channel. Our Video Ad Export Settings for Social Platforms guide is a useful companion resource if Pinterest is just one line item in a broader checklist that also covers TikTok, Meta, and YouTube Shorts.

Safe Zones and Text Placement for Pinterest

Pinterest overlays its own interface elements on top of video pins — profile info, save button, and sometimes a title or description — which means the edges and lower portion of your frame are at risk of being covered. Treat the outer margin of your video as a buffer zone, not a place for your call to action, logo, or offer text.

A few practical placement rules:

• Keep your primary hook or headline in the upper two-thirds of the frame, not tucked into the bottom strip.
• Center your most important visual (product, price, offer) rather than pushing it to a corner.
• Leave consistent margin on all sides — a simple habit is to design as if the outer 10 percent of the frame on each edge could be covered.
• Test your export by viewing it at actual mobile size before publishing, since safe zones that look fine on a desktop preview can feel cramped on a phone.

If text placement across platforms is a recurring headache for your team, our Video Ad Safe Zone Guidelines for Text piece breaks down safe-zone thinking in more depth, including how it differs between feed, story, and full-screen placements.

Sound Design for Pinterest Video Ads

Many people scroll Pinterest with sound off, especially in public or shared spaces, so your ad needs to communicate its hook and offer visually before you ever rely on audio. Design the opening few seconds assuming no sound will play, then layer voiceover and music as reinforcement rather than the primary carrier of your message.

Good habits for sound-off-first Pinterest ads:

• Put your hook in on-screen text, not just in a voiceover line.
• Use word-by-word or short-burst captions timed to match a voiceover, so the ad reads clearly even muted.
• Reserve sound effects and music for pacing and polish, not for delivering information the viewer needs.
• Test your ad with the volume down before you ship it — if the message disappears, the edit needs more on-screen support.

For a deeper playbook on this exact problem, see Boosting Engagement for Muted Video Ads and Visual Storytelling for Sound Off Video Ads. Both apply directly to Pinterest, since its scroll behavior rewards the same muted-first thinking as Stories and Reels.

Building a Pinterest Video Ad Checklist Before You Upload

Before you push a new Pinterest video ad live, run through a short checklist rather than relying on memory. Specs are easy to get wrong when you are juggling multiple platforms in the same afternoon.

1. Confirm aspect ratio matches the placement you are buying (vertical or square, not widescreen, for most campaigns).
2. Check runtime against your target — short for direct response, longer only if the format calls for it.
3. Preview the ad at phone size to confirm text and logo sit inside the safe zone.
4. Watch the ad muted first, then with sound, to confirm it works in both states.
5. Verify file type, codec, and file size against Pinterest's current ad specs page, since these details can shift.
6. Check that your call to action and offer are legible in the first few seconds, not buried near the end.

Teams that run ads across TikTok, Meta, YouTube Shorts, and Pinterest at the same time often standardize on one master vertical edit and then adapt crop and safe zones per platform, rather than rebuilding from scratch each time. That single-source approach is also where tracking what actually moves the needle matters — if you are not yet measuring which versions perform, our guide on Metrics to Track for Video Ad Performance is a useful next read once your specs are sorted.

How FrameNotion Fits Into a Pinterest Workflow

FrameNotion is built for the exact repurposing problem described above. You paste a product or website link, and FrameNotion AI writes and renders a custom 30-second vertical video ad from scratch — no templates, with a hook, problem, benefit, proof, offer, and call to action structured in. Every ad also comes out as 4:5, 1:1, and 16:9 versions alongside the 9:16 original, which gives you a square option and a widescreen option to adapt toward Pinterest's preferred formats without starting over. A quick crop to Pinterest's exact vertical or square dimensions is usually all that's left once you have the 1:1 or 9:16 export in hand.

Because Pinterest ads need to hold up with sound off, it helps that FrameNotion ads are designed to work on mute by default: word-by-word captions, on-screen copy, and a beat-matched music track are included, with voiceover and sound effects layered in only where they add value. If you need to adjust copy, colors, or swap a hook variant after reviewing the first render, the AI takes a limited number of change requests per ad depending on your plan, so you are not re-briefing from zero for a platform-specific tweak. You can see finished examples on the examples page or check exactly how the process works on features before trying it on your own product link.

Keeping Your Pinterest Specs Current

Specs pages change, and the safest habit is to treat any written guide — including this one — as a strong starting framework, then do a five-minute check of Pinterest's current ad specifications before a big send. Build your creative with vertical-first thinking, muted-first sound design, and generous safe zones, and you will be close to compliant even if a minor number shifts between your last check and your next campaign.
