Waveform Videos for Instagram, TikTok & YouTube: Sizes and Tips

By Damien Yvert · Published 5 August 2026 · 4 min read · Written with AI assistance

What size should a waveform video be?1080×1920 for TikTok, Reels and Stories; 1080×1080 for an Instagram feed post; 1920×1080 for YouTube. Set the resolution before exporting rather than cropping afterward — the waveform is laid out to the canvas, so a vertical export is composed for vertical.

Keep the clip short and the color bright: these feeds autoplay muted, so the motion of the waveform is what stops the scroll.

A waveform video only works on social if it fits the frame and reads while muted. Here are the dimensions and settings that matter for each platform, and a few habits that keep your clips looking sharp.

The same waveform frame at three export shapes side by side, labelled 16:9, 1:1 and 9:16. — One frame, three export shapes. The waveform is laid out to the canvas, so a vertical export is not a crop of the wide one.

Dimensions by platform

Instagram / TikTok Reels & Stories: 1080×1920 (9:16, vertical).
Instagram feed: 1080×1080 (1:1, square) or 1080×1350 (4:5).
YouTube (landscape): 1920×1080 (16:9).
YouTube Shorts: 1080×1920 (9:16).

Set the output resolution in Music Waveform, the free waveform video maker, before exporting so the waveform is composed for that shape rather than stretched afterward.

Design for muted autoplay

Most feeds autoplay muted, so the visual has to carry the first second. A moving waveform does exactly that — it signals sound and creates motion. Push it further with:

A bright, on-brand waveform color (dark colors get lost — see choosing colors).
Burned-in captions or a title, added over the exported clip in your editor.
A background image or brand color, composited behind the waveform with Screen — see adding a waveform over video.

Keep it short

For Reels, Shorts and TikTok, 15–30 seconds of the strongest moment beats a full track. If you're clipping a podcast, that's exactly an audiogram.

Export note: for long tracks the tool defaults to the first 30 seconds and offers a "whole track" option. For social clips, the 30-second default is usually all you want anyway.

From audio file to post

If you're starting from a bare audio file, the whole path is just converting the MP3 to an MP4 at the right size, then uploading. No app install, no watermark.
