Instagram Image and Video Sizes, Ratios and Formats: A Quick Reference

Updated: 2026-10-28 · 6 min read

How big is a saved Instagram file, what format is it, can it be enlarged for print: these come up constantly when organizing material. This quick reference collects the common specifications and what they mean for saving, organizing and reusing. Platform specifications change over time, so the numbers below describe common cases, not fixed rules.

Common aspect ratios

• Square (1:1): the classic post shape, commonly 1080×1080 pixels.
• Portrait (4:5): the most used post shape today and the one that takes the most room in the feed, commonly 1080×1350 pixels.
• Landscape (about 1.91:1): commonly around 1080×566 pixels; it looks narrow in the feed.
• Full-screen vertical (9:16): the standard shape for Reels and Stories, commonly 1080×1920 pixels.

Typical file formats

• Images: usually JPEG, occasionally PNG or WebP. JPEG is the norm for photographs.
• Video: usually an MP4 container, commonly H.264 video with AAC audio, a combination nearly every device can play.
• Mixed carousels: images and videos can share one carousel, and each is saved as its own file type.

Why saved images are usually about 1080 pixels wide

Instagram resizes and compresses images when they are uploaded, and the version shown on the platform is normally stored to the specifications above. Even if the creator’s camera original is several thousand pixels wide, what you can save from Instagram is usually a version around 1080 pixels wide. That is the ceiling set by the platform, not a loss caused by the saving tool. See why Instagram has no save-original button.

How to check a saved file

• On a computer, open the file’s details or properties and read the width, height and type.
• For video, any player will show resolution, duration and codec.
• The same item saved at different times should have the same specs; a big difference usually means the creator re-uploaded it.
• A file noticeably smaller than 1080 pixels was most likely small when it was uploaded.

Can it be enlarged for print?

At the usual 300 dpi print standard, an image 1080 pixels wide gives only about 9 centimeters (3.6 inches) of sharp output. That suits small reference prints; blown up to a poster it will look soft. For large prints, ask the creator for the original file and for permission for print use.

If you are posting your own work

• Use 4:5 portrait where you can; it takes the most space in the feed.
• Keep key text and the subject in the middle so interface elements do not cover them.
• Resize to about 1080 pixels wide before uploading to limit the loss from a second round of compression.
• Use 9:16 for Reels and Stories and keep important content inside the safe zones at the top and bottom.
