Instagram Story Ad Dimensions: What You Need to Know
Standard size and aspect ratio
Per Meta's Business Help Center, Instagram Stories ads use a 9:16 aspect ratio. The recommended resolution is 1080 × 1920 px. The minimum accepted resolution is 600 × 1067 px.
Shoot for 1080 × 1920. The minimum works, but higher resolution looks sharper on modern screens.
Why 9:16 matters for full-screen display
Stories fill the entire phone screen. Any other ratio leaves black bars or forces cropping. 9:16 gives your ad the full canvas.
Meta accepts a 3% aspect ratio tolerance. But don't rely on it. Build to 9:16 from the start.
File formats and size limits
Meta accepts JPG and PNG for Story image ads. Maximum file size is 30 MB. Compress your image without sacrificing visual quality before uploading.

Step-by-Step: How to Resize Your Image for Instagram Story Ads
Follow these steps in order. Skipping any one of them causes problems at upload.
Verify your starting image dimensions
Check your current image size before doing anything else. Most design tools show dimensions in a file info panel. Know what you're working with.
If your image is already 9:16, you may only need to upscale. If it's 1:1 or 16:9, you need a full resize and crop.
Choose your resizing method
You have three options:
- Manual resize in a design tool like Canva or Photoshop
- Smart Resize in Coinis Revise — one click, correct Story dimensions, no cropping guesswork
- Start fresh with Coinis Image Ads, which outputs at the right Story dimensions natively
Smart Resize is the fastest path for any existing creative.
Apply the correct dimensions and aspect ratio
Set your canvas to 1080 × 1920 px. Lock the aspect ratio at 9:16. Resize or reposition your visual to fill the frame.
Do not stretch to fit. Reposition and crop intentionally. Important elements belong in the center of the frame, not near the edges.
Check the safe zone boundaries
Per Meta's documentation, keep critical elements out of the top ~250 px and the bottom ~340 px. That's where platform UI overlaps your ad. Profile icons sit at the top. CTA buttons sit at the bottom.
Check placement before exporting. Move text and logos into the central safe area.

Best Practices for Story Ad Visuals
Good dimensions are necessary. Placement within those dimensions decides visibility.
Understanding safe zones (avoiding UI overlap)
Meta's safe zone guidance is clear. The top ~14% (~250 px) and bottom ~20% (~340 px) are UI territory. Your brand name, headline, and product shot must sit between those bounds.
Design for the center. Treat the safe zone as your real canvas.
Maintaining image quality during resize
Upscaling a low-res image degrades quality. Start with the largest version of your asset. If your source file is small, use AI Upscale in Coinis Revise before resizing.
Export as PNG for graphics-heavy ads. Use JPG for photo-based creatives. Both formats are accepted by Meta.
Choosing between single-card and carousel formats
Single Story image ads use the standard 1080 × 1920 px at 9:16. Carousel Story ads follow the same aspect ratio and resolution.
Carousel formats suit multi-product showcases or step-by-step storytelling. Single cards work for one strong offer. Both require the same safe zone discipline.

Common Resizing Mistakes to Avoid
Stretching or distorting your image
Forcing a 1:1 or 16:9 image into a 9:16 canvas without cropping distorts proportions. Always crop and reposition. Never stretch.
Ignoring safe zone padding
Text or logos placed in the top ~250 px or bottom ~340 px get covered by Meta's UI. The viewer never sees them. Keep all important elements inside the central safe zone.
Uploading at below-minimum resolution
Meta's minimum is 600 × 1067 px. Images below that threshold may be rejected or render poorly. Check dimensions every time before upload.
