The Basics of Instagram Stories Ad Specs

Before creating your ad, it’s essential to know the fundamental specifications required for Instagram Stories. These guidelines ensure your content displays properly and delivers the intended message to your audience.

  • Aspect Ratio: 9:16 (Full-Screen Vertical)
  • Resolution: Minimum 1080 x 1920 pixels
  • File Format: JPG, PNG (for images) and MP4, MOV (for videos)
  • File Size: 30 MB for images, 4 GB for videos
  • Length:
    • Up to 15 seconds per story frame for videos
    • Static images are displayed for 5 seconds

Adherence to these specs ensures your ad looks polished and professional, no matter the device. Instagram automatically crops and resizes content that doesn’t fit these parameters, but this can result in low-quality or poorly aligned ads.

Image vs. Video: Which Format Should You Use?

When running Instagram Stories ads, both image and video formats have their place. However, videos often perform better due to their dynamic and engaging nature.

Can have higher production costs

Videos allow you to showcase your product in action, deliver multiple messages, and capture attention through movement and sound. However, creating high-quality video ads requires more resources, so static images may be a cost-effective option for brands just starting out.

Designing for Maximum Impact

While following the specs is essential, your design choices determine whether the ad stands out in users’ feeds. Here are some tips to make your Instagram Stories ads more effective:

  1. Add Text Strategically: Place text near the center to avoid overlap with Instagram’s interface elements (like the swipe-up bar or profile icons).
  2. Include a Call-to-Action (CTA): Encourage viewers to take action with clear CTAs like “Swipe Up” or “Shop Now.”
  3. Leverage Bold Visuals: Use bright colors, sharp images, and minimal clutter to grab attention immediately.
  4. Sound On or Off: While many users view Stories with sound off, adding captions ensures your message gets across regardless.

Why Specs Matter: The Impact on Ad Performance

Failing to adhere to Instagram Stories ad specs can negatively impact performance. Poorly formatted ads might look blurry or cut off, leading to wasted ad spend and lower engagement rates.

A Case Study in Specs Compliance

A fitness brand created an ad showcasing their new product. The initial design didn’t adhere to Instagram’s resolution requirements, resulting in pixelated visuals that drove viewers away. After revising the ad to meet specs, engagement rates increased by 45%, and the campaign achieved a 12% higher return on ad spend.

Instagram Stories Ad Specs Checklist

To ensure your ads comply with all technical requirements, use this checklist before launching:

  • Is the aspect ratio 9:16?
  • Is the resolution at least 1080 x 1920 pixels?
  • Is the file format compatible (JPG, PNG, MP4, MOV)?
  • Is the ad within the file size limits?
  • Does the ad include a clear CTA?

Double-checking these details can save you time and money while improving the performance of your campaigns.
