Instagram Story Dimensions: The Complete Guide (2026)

Getting your Story dimensions wrong is one of the most common mistakes Instagram creators make. Either the image gets cropped in unexpected ways, or Instagram adds ugly grey bars on the sides, immediately killing the full-screen immersive feel that makes Stories effective.

The Ideal Instagram Story Size

The recommended dimensions for Instagram Stories are 1080 × 1920 pixels at a 9:16 aspect ratio. This is full HD vertical video/image format — the same as modern smartphone screens shot in portrait orientation.

If your image is wider (like a 16:9 landscape photo at 1920×1080), Instagram will shrink it to fit the 9:16 frame and add blurred background bars on the top and bottom. This looks unprofessional for brand content. If your image is taller than 9:16, it will be cropped horizontally.

Instagram Story Safe Zones

Instagram overlays its UI elements on top of your Stories. This means the top and bottom of your image/video will be partially hidden behind:

• Top ~250px: Profile picture, username, time indicator, and close (X) button
• Bottom ~250px: "Send message" reply bar, and the swipe-up/link sticker area

The safe zone — where your content is fully visible without any UI overlap — is the middle section: approximately 1080 × 1420 pixels (leaving 250px margin top and bottom on a 1920px tall image).

Never place important text, faces, or call-to-action elements in the top or bottom 13% of your Story canvas.

File Size and Format Limits

For images, Instagram accepts JPG, PNG, and BMP. The technical maximum is 30MB, but for reliable uploads and best quality after Instagram's compression, keep image files under 8MB. For videos, Instagram accepts MP4 and MOV (H.264 codec), up to 4GB, but practically anything under 250MB uploads without issue. Story videos can be up to 60 seconds long.

Instagram Reels vs Stories: Dimension Differences

Both Reels and Stories use the 9:16 aspect ratio and the same 1080×1920px ideal dimensions. However, the safe zones are different:

• Stories safe zone: Top 250px and bottom 250px are covered by UI
• Reels safe zone: The bottom ~35% (672px) is covered by the Reels interface — likes, comments, share, sound label

For Reels, keep all text and key visual elements in the top 65% of the frame. For Stories, keep content in the middle 74% (leaving equal margins top and bottom).

Frequently Asked Questions

What is the correct size for an Instagram Story?

The ideal Instagram Story size is 1080 × 1920 pixels with a 9:16 aspect ratio. The minimum width is 500 pixels. Instagram will crop or add padding to images that don't match this ratio.

What are the safe zones for Instagram Stories?

The top 250px is covered by the profile header (username, close button). The bottom 250px is covered by the reply bar. Keep all important content in the middle 1080 × 1420px safe zone.

What is the maximum file size for an Instagram Story?

For images, Instagram supports files up to 30MB but recommends under 8MB. For videos, the limit is 4GB but under 250MB is recommended. Videos can be up to 60 seconds long.

Does this checker work for Reels too?

Yes. Reels use the same 9:16 aspect ratio and 1080×1920px ideal dimensions as Stories. Safe zones differ slightly — keep content away from the bottom 35% which is covered by the Reels UI.

My image is 1080×1350 — will it work for Stories?

That's a 4:5 ratio (portrait feed post size). For Stories, Instagram will add grey bars on the top and bottom to fill the 9:16 frame. It will display, but it won't fill the full screen. Resize to 1080×1920 for the best Story experience.
