# Reels ads vs Stories ads > Reels ads sit between organic Reels and run up to 15 minutes. Stories ads sit between Stories and may split from 16 seconds. Specs checked 20 Oct 2026. - **Author**: Marxx - **Published**: 2026-11-16 - **Category**: Meta - **URL**: https://marxx.ai/library-compare/reels-vs-stories-ads --- Both are full-screen, vertical placements, so one 9:16 video can serve both. Reels ads appear between organic Reels. Stories ads appear between organic Stories. Run both through Advantage+ placements, then cut a separate version if a test shows one placement needs it. ## Side by side This is Instagram, from Meta's Ads Guide video specs, checked 2026-10-20. | | Reels ads | Stories ads | |---|---|---| | Where it shows | Between organic Reels, in a viewer that scrolls vertically | Between organic Instagram Stories | | Ratio | 9:16 | 9:16 | | Recommended size | 1440 x 2560 pixels | 1440 x 2560 pixels | | Video length | 0 seconds to 15 minutes | 1 second to 60 minutes | | Plays in full | Not stated | Under 16 seconds. 16 seconds or longer may split into 1 to 3 cards | | Primary text | 44 characters | 125 characters | | Viewers can | Comment, like, save, share and skip | Not stated | | Sound | Optional, strongly recommended | Optional, recommended | | File types | MP4, MOV | MP4, MOV, GIF | | Do not include | Licensed music, face or camera effects, GIFs, product tags | Not stated | Specs change, so check the limit in Ads Manager when you upload. Sources: Meta's Ads Guide pages for [Reels video](https://www.facebook.com/business/ads-guide/update/video/instagram-reels) and [Stories video](https://www.facebook.com/business/ads-guide/update/video/instagram-story). ## The three differences that matter **1. Length.** A Stories ad under 16 seconds plays in full. One of 16 seconds or longer may be cut into separate cards, and Instagram decides how many each viewer sees. Meta's Reels spec mentions no such split. **2. Text.** Reels ads allow 44 characters of primary text. Stories allow 125. Write the Reels line short, or put the message in the video itself. **3. Viewer actions.** Meta says people can comment on, like, save, share and skip Reels ads. A Reels ad has to earn attention from the first second. ## The safe zone is the same Meta advises leaving about 14% of the top, 35% of the bottom and 6% on each side free of text and logos. The profile icon and the call-to-action button sit there. A worked example. Your frame is 1440 x 2560 pixels. - Top: 2,560 x 14% = about 358 pixels - Bottom: 2,560 x 35% = 896 pixels - Each side: 1,440 x 6% = about 86 pixels Your safe box is about 1,268 pixels wide (1,440 - 2 x 86) and 1,306 pixels tall (2,560 - 358 - 896). Keep the hook and the offer inside it. ## How to run both - Meta's [Instagram help page](https://www.facebook.com/help/instagram/546362593027755) says that when Advantage+ placements is on, Meta includes Reels ads in your campaign (checked 2026-10-20).

For Stories, trim it under 16 seconds so it plays in full. ### Do Reels ads need sound? Sound is optional, but Meta's ads guide strongly recommends it for Reels. Its help page also recommends music or sound to fit the Reels placement (checked 2026-10-20). --- - [More Meta articles](https://marxx.ai/library-compare/category/meta) - [All articles](https://marxx.ai/library-compare)
