> Quick answer: Instagram Feed vertical ads need a 4:5 ratio (1080x1350 px). Stories and Reels need 9:16 (1080x1920 px). Leave 180 px clear at the top and bottom of fullscreen placements. Hook viewers in the first half-second. Use the right ratio per placement or Meta will auto-crop your creative.

Understanding Instagram Vertical Ad Formats
Vertical ads fill more of the mobile screen. More screen means more attention and more chances to convert.
What makes a vertical ad different from other formats
Landscape ads were built for desktop monitors. Vertical ads were built for thumbs. On a phone held upright, a vertical creative fills the viewport. A landscape crop gets padded with black bars. Users scroll past it before it registers.
Why mobile-first design matters for Instagram
Instagram is a mobile-native platform. Most users see your ad on a phone held upright. Vertical formats occupy the most screen real estate in that context. Mobile-optimized ads consistently outperform landscape alternatives on this channel.
The three main vertical placements: Feed, Stories, and Reels
Each placement has its own format rules. Instagram Feed vertical, Instagram Stories, and Instagram Reels each require specific dimensions. Get one wrong and the platform auto-crops your creative. That crop rarely looks intentional.

Vertical Ad Specifications by Placement
The right dimensions prevent forced crops and wasted impressions. Per Meta's Ads Guide, each placement has a recommended spec.
Instagram Feed vertical ads (4:5 aspect ratio, 1080x1350 px)
Feed vertical ads run at 4:5. The recommended size is 1080x1350 pixels. This ratio is taller than square but shorter than fullscreen. It dominates the feed on mobile without bleeding into the Stories format territory.
Instagram Stories ads (9:16 aspect ratio, 1080x1920 px)
Stories are fullscreen vertical. Per Meta's documentation, 9:16 at 1080x1920 pixels is the recommended size for Stories ads. Anything else gets cropped or padded. Cropped means lost context. Padded means dead space eating your real estate.
Instagram Reels ads (9:16 aspect ratio, 1080x1920 px)
Reels ads match Stories exactly: 9:16, 1080x1920 px. The format is fullscreen. Users are in a fast-scroll mindset. Your creative competes directly with organic Reels content, so it needs to feel native to that environment.

Core Design Principles for Vertical Ads
Correct specs get your ad displayed. Good design makes it perform.
Safe zones and avoiding text overlap with platform UI
Meta's creative optimization documentation for Stories specifies a safe zone practice. Leave approximately 180 pixels clear at the top and bottom of fullscreen vertical ads. Profile names, CTA buttons, and engagement icons all live in those zones. Critical text or faces placed there will be hidden or cut off.
Composition for fast scrolling and mobile viewing
Center your main subject. This applies across all three placements. Meta automatically crops off-center content when ads run across multiple placements. A centered composition survives any crop. An edge-heavy layout does not.
Color contrast and legibility on small screens
Mobile screens vary in size, brightness, and ambient lighting. High contrast between text and background is not optional. A dark overlay behind light text helps. Light text on a light background makes copy invisible. Preview every ad on a real phone before publishing.
Hook viewers in the first frame
Users decide to watch or skip in under half a second. The first frame carries most of the weight. Lead with your strongest visual. Put your product or brand front and center from frame one. Save any setup or storytelling for later in the creative.

Visual and Copywriting Best Practices
Strong specs and composition take you far. Creative quality closes the gap.
High-quality, eye-catching imagery
Blurry or low-resolution images signal low quality instantly. Use source images at 1080 pixels wide at minimum. Coinis Image Ads generates vertical creatives directly from a product URL, so you always start with the right dimensions and resolution.
Clear, concise copy that drives action
Vertical space is tall, not wide. Long text lines wrap awkwardly and look cluttered. Keep headlines short. One idea per line. One clear CTA per ad. Meta's text policy also limits heavy image text overlays, so lean copy protects your delivery.
Brand consistency across all placements
Your Feed ad, Story ad, and Reels ad should feel like the same brand. Same fonts, same color palette, same tone. A viewer who sees your Feed ad and then encounters your Story should recognize you immediately.
Video vs. static images for vertical ads
Both formats work well. Static images load fast and suit simple product shots or promotions. Video Reels ads perform best at 15 to 30 seconds in 9:16 format. Longer risks scroll fatigue. Shorter can feel abrupt. For Reels, video feels more native. For Feed, static converts just as reliably.

Resizing and Optimizing Across Placements
Running one campaign across multiple placements means managing multiple ratios.
Why you need different sizes for Feed vs. Stories/Reels
A 4:5 Feed creative pushed into a 9:16 Stories slot gets letterboxed with black bars. A 9:16 Stories creative shown in Feed gets cropped to 4:5, often removing key elements from the top or bottom. Each placement deserves its own asset.
How to resize without losing quality or composition
Manual resizing in traditional design tools means repositioning every element by hand. Coinis Revise handles this with Smart Resize. Upload your creative, pick the target ratio, and the AI adjusts composition automatically. Text stays readable. Key visuals stay centered. Resolution stays sharp.
Testing multiple aspect ratios to find winners
Running the same creative at both 4:5 and 9:16 across placements lets you measure which ratio drives better results for your specific audience. More variations produce more data. More data leads to smarter budget decisions over time.

Common Mistakes to Avoid
Dodge these and your vertical ads will outperform most of what runs in the feed.
Using landscape images or wrong aspect ratios
A 16:9 landscape image in a vertical placement loses much of its screen area to letterboxing. Start with vertical source assets. Adapting landscape to vertical after the fact almost never looks right.
Ignoring safe zones and text placement
A headline pinned to the very bottom of a Stories ad disappears behind the CTA button. Always respect the 180-pixel buffer at top and bottom. Design for the safe zone, not the full canvas.
Overloading copy in vertical space
Tall does not mean more room for text. Users scan fast. If your ad looks like a paragraph, they scroll. Keep copy to three lines or fewer on static vertical ads.
Not optimizing for mobile-first experience
Designing at full zoom on a desktop monitor is the fastest path to an ad that fails on a phone. Preview every vertical creative at real phone size before it goes live. What looks balanced on a large monitor can look cluttered on a 6-inch screen.

Frequently Asked Questions
What aspect ratio should I use for Instagram vertical ads?
It depends on the placement. Instagram Feed vertical ads use a 4:5 ratio (1080x1350 px). Instagram Stories and Reels ads both use 9:16 (1080x1920 px) for a fullscreen vertical experience. Using the wrong ratio for a placement causes Meta to auto-crop or letterbox your creative.
What is the safe zone for Instagram Stories ads?
Leave approximately 180 pixels clear at the top and bottom of your fullscreen vertical (9:16) creatives. Platform UI elements like the profile name, CTA button, and engagement icons sit in those zones. Any critical text or visuals placed there will be covered or cut off.
Can I use the same creative for Instagram Feed and Stories ads?
Not without resizing. Feed vertical ads are 4:5 and Stories ads are 9:16. Pushing a 4:5 creative into Stories adds black bars. Pushing 9:16 into Feed crops the top and bottom. Each placement needs a properly sized asset to display correctly.
How long should a vertical video ad be for Instagram Reels?
Aim for 15 to 30 seconds in 9:16 format. Shorter can feel abrupt and cut off your message. Longer risks scroll fatigue in a fast-moving Reels feed where users are accustomed to quick, native-feeling content.
