Instagram Story ads reach your audience full-screen, with zero distractions. This guide covers the specs, setup steps, and design tips you need to get a Story ad live fast.
What is an Instagram Story Ad?
Story ads are paid placements inside the Instagram Stories feed. They look native. They reach people who have never heard of your brand.
Full-screen vertical format
Story ads fill the entire phone screen. The 9:16 aspect ratio uses every pixel of a vertical display. Nothing else competes for attention.
Appears between organic stories
Your ad slots between the stories users already watch. Swipe behavior keeps viewers engaged. You get a few seconds of undivided attention before they move on.
Ideal for mobile-first audiences
The format is built for phones. No sidebars. No banners. No feed clutter. Full-screen visibility makes Story ads one of the strongest mobile placements available.
Instagram Story Ad Specifications
Per Meta's Ads Guide, Story image ads have specific requirements. Get these right before you build a single pixel.
Image dimensions and aspect ratio
- Recommended resolution: 1080 x 1920 pixels (or up to 1440 x 2560 pixels for higher quality)
- Aspect ratio: 9:16
- Minimum width: 500 pixels
- Aspect ratio tolerance: 1%
Always design at 1080 x 1920 or higher. Lower-resolution images look blurry on modern phone screens.
File type and file size limits
Per Meta's Ads Guide:
- Accepted file types: JPG or PNG
- Maximum file size: 30MB
Compress images before uploading. Large files slow load time on mobile connections.
Safe zones for text and branding
Meta's documentation states you must leave 14% (roughly 250 pixels) at the top and 20% (roughly 340 pixels) at the bottom free from text and logos. The viewer's profile icon sits at the top. The CTA button sits at the bottom. Place all critical visuals and copy in the middle zone.
Duration and display behavior
Image Story ads display for 5 to 16 seconds. The ad ends when the viewer swipes forward or the timer runs out. It is short. Design for the first glance, not a long read.
Step-by-Step. Create an Instagram Story Ad
Prepare your creative asset
Build your image at 1080 x 1920 pixels. Use JPG or PNG. Keep the file under 30MB. Place your headline and product visuals inside the safe zone. Keep copy concise. The primary text character limit is 125 characters.
Set up your ad in Meta Ads Manager
Go to Meta Ads Manager and click Create. Select your ad account. Meta guides you through a structured campaign setup flow from here.
Choose your campaign objective and audience
Pick one campaign objective. Options include Awareness, Traffic, Leads, and Sales. Define your audience by location, age, interests, or custom audiences from your customer list. Specific audiences outperform broad ones in Story placements.
Configure placements and budget
Under placements, choose Manual Placements. Select Instagram Stories only. This isolates the format so your creative is never stretched or misfit into a feed unit. Set a daily or lifetime budget. Start small and review before scaling.
Review and launch
Preview the ad using the Stories mockup inside Ads Manager. Confirm no text or logo overlaps the safe zones. Check your destination URL or app link. Click Publish.
Design Tips for High-Performing Story Ads
Good specs get your ad approved. Good design gets results.
Keep brand/logo visible in first 3 seconds
Per the Meta Business Help Center, show your brand within the first 3 seconds. Viewers swipe fast. Brand early or lose the impression entirely.
Use clear call-to-action copy
One message. One action. Tell people exactly what to do. "Shop now", "Get 20% off today", and "Book your free demo" all work. Vague copy does not.
Leave safe zones at top and bottom
Keep the top 250px and bottom 340px completely clear of text and logos. The profile icon and CTA overlay those areas. Your creative disappears if you ignore this.
Test variations
Run two or three creative variants at the same time. Different headlines. Different visuals. Different color palettes. Small changes often produce big differences in click-through rate.

Frequently Asked Questions
What size should an Instagram Story ad image be?
Use 1080 x 1920 pixels at a 9:16 aspect ratio. For the highest quality, 1440 x 2560 pixels is supported. Minimum width is 500 pixels. Maximum file size is 30MB. Accepted formats are JPG and PNG.
What are the safe zones for Instagram Story ads?
Leave the top 250 pixels (about 14% of the frame) and the bottom 340 pixels (about 20%) free from text and logos. Instagram overlays the viewer's profile icon at the top and the CTA button at the bottom. Any creative element in those areas will be covered.
How long does an Instagram Story ad display?
Image Story ads display for 5 to 16 seconds, or until the viewer swipes forward. Design your creative to communicate the core message in the first few seconds.
How do I make sure my Story ad only shows in Stories and not in the feed?
In Meta Ads Manager, choose Manual Placements during campaign setup. Then select only Instagram Stories. This prevents your 9:16 creative from appearing in feed placements where it would be cropped or letterboxed.
