Spotify Ad Specs and Sizes: Complete 2026 Guide

Spotify ad specs cover the audio encoding, companion image dimensions, Canvas video limits, and character counts every Spotify campaign needs. Because Spotify is primarily an audio surface, the audio file is the hero and the visual is a supporting companion.

Spotify serves audio and video ads to free-tier listeners between songs and in podcast breaks. The specs below apply to Ads Manager and most programmatic buys. Match them exactly so your spot clears review and plays at the right speed.

Why These Specs Matter

Why Spotify specs matter: audio that is encoded at the wrong sample rate or loudness can play back at the wrong speed or feel jarring next to a listener's playlist, which hurts completion more than any visual ever could. Spotify also enforces HTTPS-only destinations and tracking, so a single http link will hold the whole campaign. The companion image and Canvas loop are where most teams under-invest: they are small, but they are the only visual memory anchor a sound-on ad gets. Build the audio to broadcast standard first, then design a 1:1 companion and a 9:16 Canvas that echo the same message, and your spot will clear review and actually get remembered. A 30-second spot is roughly 65 words of script, so write to that limit and leave room for a logo and a single call to action rather than a paragraph of fine print.

Quick Format Selection Cheat Sheet

The fastest way to pick a format is to start from your campaign goal, then match it to the envelope above. For pure reach on a phone-first audience, the single image or video format is the safest launch pad. For catalog-driven retail, the collection or shopping format keeps product tiles consistent. For brand storytelling, the longer video and AR or interactive formats earn more dwell time but demand stricter adherence to the encoding rules. In every case, export at the recommended resolution first and downscale only if a placement requires it, because upscaling a smaller asset is what produces the blur and rejection most teams blame on the platform rather than on their export settings. Keep one master template per platform at the native aspect ratio, and new creative becomes a resize rather than a rebuild.

Common Spec Mistakes to Avoid

The Spotify mistakes that waste the most time are stereo tracks bounced as mono, audio mastered hotter than -16 LUFS, and http (not https) landing pages. Each one holds the campaign at review rather than rejecting it outright, which is worse because the spend clock is already running. Master to broadcast spec, confirm the destination is https before you submit, and keep the companion image at 1:1 under 200 KB. Treat the audio file as the creative, not a technical afterthought, and your spot clears on the first attempt.

Pre-Launch Checklist

Export audio at 44.1 kHz, 192 kbps minimum, -16 LUFS, stereo, and keep the Ad Studio file under 1 MB.
Build the companion display image at 1:1, at least 600 x 600 pixels, JPG or PNG, under 200 KB.
Create a 9:16 Canvas loop, 720 x 1280 to 1080 x 1920 pixels, MP4 or JPG, under 8 MB, 3 to 8 seconds.
Set advertiser names to 30 characters, podcast names to 25, taglines to 40, and CTA copy to 40 characters.
Point every destination and tracking pixel to an https URL and preview the spot in Ad Studio before launch.
For programmatic buys, submit OGG-encoded audio and verify the DSP fires only https tracking pixels into Spotify.

How Do I Avoid Spotify Ad Rejection?
