Stories Ad Format
Stories ads appear between organic Stories in the Facebook and Instagram Stories viewer — the horizontal tap-through strip at the top of the app. Users are in a fast-paced consumption mode: tapping rapidly through friends' Stories, encountering the ad, and either engaging or tapping past within seconds. The creative must immediately signal relevance to earn attention.
Stories ads can be static images (shown for 5 seconds) or videos (up to 60 seconds, though 15 seconds is optimal). The format is exclusively vertical — 9:16 full-screen. There is no "skip after 5 seconds" option for users — they must tap to advance.
Stories Ad Specifications
| Element | Specification |
|---|---|
| Image dimensions | 1080 x 1920 px (9:16); minimum 600 x 1067 px |
| Video dimensions | 1080 x 1920 px (9:16) strongly recommended |
| Supported aspect ratios | 9:16 recommended; 1.91:1 to 9:16 technically supported (non-9:16 shows with coloured borders) |
| Image file formats | JPG, PNG |
| Video file formats | MP4, MOV |
| Maximum image file size | 30 MB |
| Maximum video file size | 4 GB |
| Image display duration | 5 seconds |
| Video length | 1 second to 60 seconds; 15 seconds recommended |
| Headline / text overlay | No dedicated headline field; text can be overlaid on creative directly or added via primary text (not shown in Stories placement) |
| CTA button | Displayed at the bottom; swipe-up or tap-to-open depending on account |
Reels Ad Format
Reels ads appear within the Instagram Reels feed and Facebook Reels — between organic short-form videos as users scroll vertically. Unlike Stories (tap-forward), Reels users scroll — they encounter the ad while in motion and may scroll past in under 2 seconds if the first frame does not hook them.
The native Reels environment is entertainment-first: organic Reels are typically humorous, educational, or surprising. Ads that feel native to this context — using similar editing styles, music, or creator-style presentation — consistently outperform polished commercial-style ads in Reels placements.
Reels Ad Specifications
| Element | Specification |
|---|---|
| Video dimensions | 1080 x 1920 px (9:16) required |
| Aspect ratio | 9:16 only (no landscape/square support) |
| Video file formats | MP4, MOV |
| Maximum file size | 4 GB |
| Minimum length | Tested from 4 seconds; 15 seconds recommended |
| Maximum length | 60 seconds for Instagram Reels ads; 60 seconds for Facebook Reels ads |
| Frame rate | Minimum 23fps; 30fps recommended |
| Audio | Strongly recommended — Reels viewers expect sound (opposite of Feed) |
| Captions | Recommended even with audio — accessibility and for sound-off viewers |
| Primary text | Displayed below the video; 72 characters before truncation |
Safe Zones — Critical for Stories and Reels
Both Stories and Reels have UI elements overlaid on the creative — profile icons, ad labels, CTA buttons, engagement icons — that obscure parts of the image or video. Placing critical content in these zones means it will be covered in delivery. The safe zone is the area guaranteed to be free from UI obstruction.
Stories safe zone
- Top 14% of the frame: reserved for the Stories progress bar, profile picture, and username
- Bottom 20% of the frame: reserved for the CTA button and ad label
- Safe zone: central 1080 x 1282 px (approximately pixels 250–1532 vertically in a 1920px tall creative)
Reels safe zone
- Top 14%: account information, sponsored label
- Bottom 35%: caption text, CTA button, engagement icons (like, comment, share), sound button
- Safe zone: central 1080 x 1000 px (approximately the upper-middle 52% of the frame)
The Reels bottom zone is much larger than Stories because of the additional engagement UI (like, comment, share icons). Product shots, faces, and key text must be in the upper-middle of the frame. Test your Reels creative in the Meta Creative Hub preview to verify nothing critical is obscured before launching.
Stories Creative Principles
- Immediate clarity. Users tap through Stories at speed. Your product or proposition must be clear in the first 1–2 seconds. Do not build up — open on the product or the offer.
- Use the full frame. Stories is full-screen. Design the creative to fill the entire 9:16 frame — not a 16:9 landscape video letterboxed with colour bars. Full-frame creative performs better than pillarboxed or letterboxed content.
- Add text overlays for the muted-majority. Like Feed video, many Stories are watched silently. Add key message text as an overlay directly on the creative (within the safe zone) — not relying on audio for message delivery.
- Direct CTA. Stories users have a clear path: swipe up (or tap the CTA button). Make the desired action explicit — "Swipe up to shop", "Tap to claim offer". Stories is a direct-response placement; the CTA should match that intent.
- Brand early. Place your logo or brand name in the upper-middle safe zone early in the creative — even users who tap past will have seen the brand.
Reels Creative Principles
- Hook in the first 2 seconds. Reels users scroll — if the first frame does not stop the scroll, you have lost the impression. Open with motion, a surprising visual, a direct question, or an immediately appealing product shot.
- Feel native, not commercial. The Reels feed is dominated by authentic creator content. Ads that feel polished and corporate interrupt the experience; ads that feel native (creator-style filming, conversational tone, organic transitions) blend in and perform better.
- Audio is expected. Unlike Feed video, Reels viewers have audio on — it is part of the format. Use sound purposefully: trending audio styles, voice-over narration, product demonstration with natural sound.
- Show, do not just tell. Reels rewards visual demonstration — product in use, transformation results, step-by-step process. Talking-head-only content without visual variety performs poorly in Reels.
- End with a clear next step. The CTA appears at the bottom — keep your closing frame simple, with the product or offer visible, and a spoken or on-screen CTA directing the viewer to swipe or tap.
