- Feed ads appear between organic posts in the main scroll and support square, portrait, and carousel formats.
- Stories ads run full-screen at 9:16 between user stories and display for 5 seconds by default.
- Feed recommended resolution is 1440×1800 px (4:5) or 1440×1440 px (1:1), max 30 MB.
- Stories recommended resolution is 1080×1920 px, with safe zones at top 14% and bottom 20% of the frame.
- Stories often cost less per impression. Feed often holds attention longer. Test both before committing budget.
- Coinis Campaign Launcher lets you pick placements manually or use automatic optimization, then publish directly to Meta.
Placement determines format. Format determines how your creative must look, how long it has to make an impression, and how users interact with it. Get this wrong and your ad underperforms before the copy is ever read.
What Are Instagram Feed and Stories Placements?
Where your ad appears shapes everything about how you build it.
Feed placement basics
Feed ads appear in the main Instagram scroll. They sit between organic posts from accounts users follow. Users browse at their own pace. A strong feed ad stops the scroll and holds attention for several seconds. That dwell time is valuable.
Stories placement basics
Stories ads appear full-screen between user stories. Per Meta's documentation, each image ad displays for 5 seconds by default before advancing automatically to the next story. Users can tap to skip or tap the CTA to follow through. The window is short. First impressions are everything.
Why placement choice matters for advertisers
Each placement has different creative requirements, viewing behavior, and typical costs. The wrong creative format in the wrong placement gets auto-rejected or ignored. Knowing the difference before launch saves budget and time.

Key Differences. Feed Ads vs Stories Ads
Placement shapes format. Format shapes results.
Format and creative requirements
Feed ads support aspect ratios from 1.91:1 to 4:5. The 4:5 portrait format takes up the most screen space in the feed scroll. Stories ads require 9:16 vertical, full-screen. A square feed image will not fill a Stories placement. These are hard requirements from Meta, not suggestions.
User engagement patterns
Feed users are in a browsing mindset. They scroll at their own pace and pause when something catches their eye. Stories users are in a rapid-tap mindset. They move fast. Your message must land in the first second, or you lose them.
Visibility and scroll behavior
Feed ads can hold attention for several seconds when the creative is strong. Stories ads get 5 seconds by default and no more. Put your product and CTA front and center in Stories. In feed, you have room for a slightly longer story arc or a carousel that users swipe through.
Performance characteristics
Stories placements typically carry lower CPMs than feed placements. More impressions per dollar. But those impressions are shorter. Feed ads tend to drive higher engagement volume. Stories can drive stronger swipe-through rates for direct-response offers. Both vary by audience, product category, and creative quality. Test before you conclude anything.

Feed Placement. When to Use It
Feed works best when you want users to study your creative.
Ideal use cases for feed ads
Use feed for carousel product showcases, before-and-after transformations, multi-benefit messaging, and brand awareness campaigns where dwell time matters. If your product needs context, feed gives you that space. High-consideration purchases and new brand introductions fit well here.
Creative best practices for feed
Use strong visual contrast to stop the scroll. Put your product in the first frame. Keep primary text under 150 characters, per Meta's current recommendation. Headline copy should land under 27 characters for clean display across placements. Avoid text-heavy images. Let the visual do the heavy lifting.
Recommended image and video specs
Per Meta's Ads Guide for image ads in Instagram and Facebook Feed:
| Spec | Value |
|---|---|
| Supported aspect ratios | 1.91:1 to 4:5 (3% tolerance) |
| Recommended resolution (1:1) | 1440 × 1440 px |
| Recommended resolution (4:5) | 1440 × 1800 px |
| Minimum resolution (1:1) | 600 × 600 px |
| Minimum resolution (4:5) | 600 × 750 px |
| File formats | JPG, PNG |
| Max file size | 30 MB |
---
Stories Placement. When to Use It
Stories ads reward speed and simplicity.
Ideal use cases for stories ads
Use Stories for flash sales, limited-time offers, app download campaigns, and any CTA that asks for a fast tap or swipe. Time-sensitive messaging fits the short-format viewing window naturally. If your offer is clear in two seconds, Stories is your placement.
Creative best practices for stories
Fill the full screen. Keep all text and logos out of the top 14% and bottom 20% of the frame. Those zones are covered by the profile handle and the CTA button. Lead with your offer in large, readable text. Motion or animation captures attention faster than a static headline in the first second.
Vertical format and specs
Per Meta's design requirements for Instagram Stories ads:
| Spec | Value |
|---|---|
| Aspect ratio | 9:16 full-screen vertical |
| Recommended resolution | 1080 × 1920 px |
| Minimum resolution | 600 × 1067 px |
| File formats | JPG, PNG |
| Max file size | 30 MB |
| Default image display duration | 5 seconds |
| Safe zone top | ~14% of frame (~250 px) |
| Safe zone bottom | ~20% of frame (~340 px) |
Keep critical elements inside the safe zones. Anything outside risks being hidden by the UI.

Choosing Between Feed and Stories in Campaign Launcher
Placement selection happens at the ad set level. It takes about 30 seconds.
How to select placements in Meta Ads Manager
In Meta Ads Manager or Coinis Campaign Launcher, navigate to the ad set. Under Placements, switch from Advantage+ Placements to Manual Placements. Then check or uncheck Instagram Feed, Instagram Stories, and any other placements you want. Only the checked placements will serve your ad.
Manual placement selection vs automatic
Advantage+ Placements (automatic) spreads your budget across Feed, Stories, Reels, Messenger, and Audience Network. This can lower your average CPM and let Meta's algorithm find efficiency. The tradeoff is that your creative needs to work across every format it touches. Manual placement gives you control. Use manual when you have placement-specific creatives built for Feed or Stories separately. Use automatic when you want Meta to allocate spend where it performs best.
Testing both placements
The cleanest test uses two separate ad sets with identical targeting. One runs Feed only. One runs Stories only. Run both for at least 7 days with equal daily budgets. Compare cost per result, not just CPM. The placement with a lower cost per result gets more budget in the next round.

Performance and Cost Considerations
Numbers matter. Context matters more.
CPM and CPC differences
Stories placements typically carry lower CPMs than Feed. More impressions per dollar. But a 5-second impression that gets tapped past in 1 second is worth less than a 4-second dwell in Feed from a high-intent user. CPM is a cost metric. It does not measure value delivered.
Conversion rates by placement
Conversion performance varies by vertical, audience, and creative quality. Ecommerce and direct-response brands often see strong results from Stories when the offer is clear and the CTA is prominent. Brand-awareness and high-consideration products often perform better in Feed where dwell time enables more persuasion. Neither placement wins universally.
How to measure which works better
Track cost per purchase, cost per lead, or cost per landing page view. Not just CTR or CPM alone. Use Meta's placement breakdown report inside Ads Manager to split results by placement. Export after your test period. Let the data decide, not assumption.

Frequently Asked Questions
What is the main difference between Instagram Feed and Stories ads?
Feed ads appear in the main scroll between organic posts and stay visible as long as users pause on them. Stories ads play full-screen between user stories for 5 seconds by default before advancing automatically. Each placement has different creative requirements, viewing behavior, and typical costs.
Do Instagram Feed and Stories ads require different creative sizes?
Yes. Feed ads support aspect ratios from 1.91:1 to 4:5, with 1440×1800 px recommended for portrait format. Stories ads require 9:16 vertical at 1080×1920 px recommended. Using the wrong size can cause auto-rejection or poor display. Per Meta's documentation, Stories also have safe zones covering the top 14% and bottom 20% of the frame.
Should I use automatic or manual placement in Meta Ads Manager?
Use automatic (Advantage+ Placements) when you want Meta to find cost efficiency across Feed, Stories, Reels, and other placements, and when your creative works across formats. Use manual placement when you have placement-specific creatives built to different aspect ratios and want full control over where your budget goes.
Which placement typically has lower CPMs, Feed or Stories?
Stories placements typically carry lower CPMs, meaning more impressions per dollar. But Stories impressions are shorter (5 seconds by default), so each impression is less engaged. Measure cost per result, not just CPM, to find which placement actually drives better outcomes for your campaign.
