Instagram Story Size: Dimensions, Format, and File Specs Explained

The correct instagram story size is 1080 x 1920 pixels, with a 9:16 aspect ratio. This applies to both photos and videos. If your content doesn't match these dimensions, Instagram will either crop it or add black bars — neither of which looks intentional.

What Is the Correct Instagram Story Size?

1080px wide by 1920px tall. That's it. Portrait orientation, vertical frame, 9:16 ratio.One thing worth clarifying upfront: 9:16 and 16:9 are not the same. 16:9 is landscape — your standard widescreen TV or YouTube video format. Stories are the opposite. Vertical. Tall. Designed for a phone held upright.

The minimum resolution Instagram will accept is 600 x 1067px, but that's the floor, not a target. In practice, uploading anything below the full 1080 x 1920px noticeably reduces sharpness, especially on newer high-resolution phone screens. Always design at full spec.

Instagram Story File Format and Size Limits

Supported File Formats

For images, Instagram accepts JPG and PNG. For videos, it accepts MP4 and MOV. If you're working with video, MP4 is the safer choice — it's compatible with virtually every device and editing tool without conversion issues.

File Size and Length Limits

Content Type	Max File Size	Max Length
Image	30MB	—
Video	4GB	60 seconds per clip

Worth noting: you can post multiple story clips back-to-back, so the 60-second limit per clip isn't as restrictive as it sounds. Most teams working at volume keep clips under 15 seconds anyway, purely for retention.

Stories remain one of the platform's most-used formats  according to Statista, over 500 million accounts use Instagram Stories every day, which explains why getting the technical specs right matters more than it might seem.

Instagram Story Safe Zone — What It Is and Why It Matters

This is the part most guides skip entirely.Even when your story is exactly 1080 x 1920px, not all of that space is visibly usable. Instagram's UI overlays your content at the top and bottom of the frame:

Top ~250px — profile photo, username, and the close friends indicator sit here

Bottom ~250px — the reply bar, link sticker area, and swipe interactions live here

Middle ~1420px — this is your actual safe zone

Keep all text, logos, CTAs, and anything visually important inside that middle band. Designers working on branded story content commonly report losing key elements to the UI overlap when this isn't accounted for — particularly on the first few story posts from a new account.

What Happens If Your Image Doesn't Match the 9:16 Ratio?

Instagram doesn't reject off-ratio images outright. Instead:A landscape image (16:9) will display with black bars above and below. A square image (1:1) gets similar treatment. An image that's close to 9:16 but not exact may get auto-cropped at the edges.

None of these outcomes are catastrophic, but they do affect how polished the content looks. Designing natively at 1080 x 1920px from the start avoids the guesswork entirely.

Instagram Story Size vs Other Instagram Format Sizes

Format	Dimensions	Aspect Ratio
Story	1080 x 1920px	9:16
Reels	1080 x 1920px	9:16
Feed Post (square)	1080 x 1080px	1:1
Feed Post (portrait)	1080 x 1350px	4:5
Feed Post (landscape)	1080 x 566px	1.91:1
Profile Picture (upload)	1080 x 1080px	1:1

Stories and Reels share the same canvas dimensions. The difference is in how they're distributed and how long they persist not the file specs.

Do Instagram Story Ads Use the Same Dimensions?

Yes. Story ads use the same 1080 x 1920px spec and the same 9:16 ratio. The safe zone rules apply here too — ad content with key information buried under the UI tends to underperform.

As reported by TechCrunch, Stories is a bigger moneymaker for Instagram than Reels, with more infrastructure in place to serve ads  which makes proper formatting even more relevant for anyone running paid placements.
