What Are Instagram Story Ads and Why They Matter
Story ads run fullscreen between a viewer's organic Stories. No competing feed content. No sidebar. Just your creative and the screen.
The Story format advantage
The fullscreen vertical format removes every distraction. The viewer either watches or taps forward. That creates a high-stakes, high-reward environment. Get the creative right and you own the entire screen for the duration of the ad.
How Story ads differ from Feed ads
Feed ads sit inside a scrolling content stream. Story ads live in the Stories bar and auto-advance one after another. Feed viewers scroll slowly. Story viewers tap fast. The pace of consumption is completely different. Your hook has to land in the very first frame.

Instagram Story Ad Specifications You Need to Know
Per Meta's design requirements, these are the specs to get right before you build anything.
Dimensions and aspect ratio
Use 1080×1920 px at a 9:16 aspect ratio. That fills the screen on every modern phone. The minimum accepted resolution is 600×1067 px, but lower-resolution creatives look soft in the feed. Stick to 1080×1920 px. Accepted file formats are JPG and PNG. Maximum file size is 30 MB.
Video length and file size limits
Image ads display for 5 seconds by default, per Meta's documentation. For video Story ads, Meta recommends keeping videos in the 5–15 second range for best engagement. Tight, fast creative performs better. Attention drops sharply after the 15-second mark.
Image vs. video ad options
Both formats work. Images are faster to produce and great for retargeting. Video supports narrative and works well for awareness. Story carousel ads support up to 5 cards, letting you build a sequential story across swipes. For most advertisers testing Story ads for the first time, a single strong image or a short 6–10 second video is the right starting point.

Step-by-Step: How to Create a Story Ad
Step 1: Start in Meta Ads Manager and choose your objective
Open Meta Ads Manager. Click "Create." Pick a campaign objective. Awareness, Traffic, Engagement, Leads, and Sales all support Instagram Stories placement. Your objective determines what Meta optimizes for, so match it to your actual goal.
Step 2: Define your audience and budget
Set your audience at the ad set level. Use age, location, interests, or a custom audience built from your customer list or website visitors. Set a daily or lifetime budget. A daily budget of $10–20 is enough to test creative performance before scaling.
Step 3: Upload or create your creative
At the ad level, select Instagram Stories as a placement or let Advantage+ Placements optimize across eligible formats. Upload your 1080×1920 px creative. Confirm the file is under 30 MB and saved as JPG or PNG for image ads.
Step 4: Set up your CTA and destination link
Pick a specific CTA button. Generic options like "Learn More" underperform specific ones tied to a clear offer. Match the CTA text to what your landing page actually delivers. Add your destination URL and confirm the page is mobile-optimized.
Step 5: Review and launch
Preview the ad in the Stories preview panel inside Ads Manager. Check that no text or CTA is cut off at the top or bottom of the frame. When everything looks clean, hit Publish.

Design Best Practices for Story Ads That Convert
Hook in the first frame
Users decide to watch or skip in under a second. Lead with a visual pattern interrupt, a bold text statement, or a face looking directly at the camera. The first frame carries the entire weight of your ad.
Keep text in safe zones
Meta's design requirements define a safe zone of approximately 250 px from the top and 340 px from the bottom of the frame. Profile names sit at the top. The reply bar and swipe-up prompt sit at the bottom. Any text or CTA placed inside those zones will be covered by UI elements. Build all your key content in between.
Use native 9:16 format
Repurposing a square or landscape Feed creative into Stories format consistently hurts performance. Native vertical content fits the context. It looks intentional. Build Stories creatives from scratch rather than cropping down Feed assets.
Add captions for sound-off viewers
A notable share of Instagram users watch Stories with the sound off. Text overlays and captions keep your message landing regardless of audio. If your ad relies entirely on voiceover or music to communicate the offer, you are losing a meaningful slice of your audience.
Match the creative to your funnel stage
Cold audiences need context and awareness. Warm audiences need a reason to act. Use Story ads to retarget people who have visited your site, watched your videos, or engaged with your posts. Pushing a hard conversion offer to someone who has never seen your brand tends to drive up costs without results.

Frequently Asked Questions
What size are Instagram Story ads?
Instagram Story ads should be 1080×1920 pixels at a 9:16 aspect ratio. The minimum accepted resolution is 600×1067 px, but 1080×1920 px is strongly recommended to fill every phone screen cleanly. Maximum file size is 30 MB for JPG or PNG images.
How long can an Instagram Story ad be?
Image Story ads display for 5 seconds by default, per Meta's documentation. Video Story ads can run longer, but Meta recommends keeping video to 5–15 seconds for best engagement. Attention drops sharply beyond 15 seconds.
What are the safe zones for Instagram Story ads?
Per Meta's design requirements, keep all critical text and CTAs at least approximately 250 px away from the top of the frame and approximately 340 px away from the bottom. Profile names sit at the top and the reply bar sits at the bottom. Any content in those zones will be covered by UI elements.
Can I reuse a Facebook Feed ad creative for Instagram Stories?
Technically yes, but it hurts performance. Native 9:16 vertical content is built for the Stories format and consistently outperforms repurposed square or landscape creatives. Build Story creatives to the correct dimensions from the start, or use Smart Resize in Coinis Revise to adapt existing assets quickly.
