The Ultimate Guide to Instagram Story Size in 2026
When you are dropping a quick behind-the-scenes clip, launching a new product, or sharing a funny meme on Instagram Stories, the last thing you want is for your brilliant visual to get awkwardly cropped, aggressively zoomed, or pixelated.
Getting your dimensions right is the secret sauce to looking polished and professional on the feed. Here is everything you need to know about Instagram Story sizes, aspect ratios, and best practices to make your content pop.
The Magic Numbers: Dimensions & Aspect Ratio
Instagram Stories are designed for mobile-first, vertical viewing. To fill the screen seamlessly without losing crucial parts of your design, stick to these exact specifications:
- Optimal Resolution: 1080 pixels wide by 1920 pixels high
- Aspect Ratio: 9:16
- Maximum File Size: 30 MB (for photos) / 4 GB (for videos)
- Supported Formats: MP4, MOV, or GIF for videos; JPG or PNG for photos
If you upload an image or video that doesn’t match this 9:16 ratio, Instagram will either automatically crop it to fit or leave awkward, empty background borders. Designing to the 1080×1920 spec gives you total control over your final output.
Safe Zones: Don’t Let the UI Hide Your Content
Even if your image is the exact right size, part of your design might still get covered up by Instagram’s user interface (UI)—like your profile picture at the top or the direct message box at the bottom.
