What size should an Instagram audiogram be?

Use 1080x1080 pixels (1:1) for a feed post, and 1080x1920 pixels (9:16) for Reels and Stories.

How long should an Instagram audiogram be?

Around 30 seconds for a feed post, 15 to 20 seconds for a Reel, and close to 15 seconds for a Story.

Can I post a square audiogram to Reels?

You can, but it will be pillarboxed with empty bars above and below the video. Export at 9:16 instead so it fills the screen.

Instagram audiogram maker, correctly sized

Instagram treats square and vertical video differently, and posting the wrong shape gets your waveform cropped or letterboxed. The short version: 1080x1080 for a feed post, 1080x1920 for Reels and Stories. Pick the matching ratio in the panel below and export.

Feed posts: square, 1080x1080

Square is the safest format for the main feed. It occupies more vertical space than a landscape video as someone scrolls, without the aggressive cropping that catches people out with portrait uploads. Select the 1:1 ratio and keep the clip to about 30 seconds.

Reels and Stories: vertical, 1080x1920

Reels and Stories are full-screen vertical at a 9:16 ratio. Anything square gets pillarboxed with empty space above and below, which reads as a repurposed post rather than something made for the format. Switch the ratio to 9:16 before exporting. Aim for 15 to 20 seconds on a Reel and around 15 on a Story.

What this tool exports

Exports anchor the long edge at 1280 pixels — so 1280x720 for landscape and 720x1280 for vertical — rather than a full 1080x1920. Instagram re-encodes every upload regardless, and 720 on the short edge stays above the threshold where its compression becomes visible on a waveform animation. If you need true 1080p masters for an archive, render elsewhere; for posting, this is indistinguishable after Instagram is done with it.
