Audiobook Cover Art Requirements: Audible, Apple, and Spotify in 2026

Your audiobook cover is the first thing potential listeners see on every platform — Audible, Apple Books, Spotify, and Google Play. Each platform has specific technical requirements. Getting them wrong means rejection or a blurry, unprofessional thumbnail. This guide covers every spec you need.

Audible / ACX Cover Requirements

• Dimensions: 2400 x 2400 pixels minimum (square)
• Format: JPEG or PNG
• Resolution: 72 DPI minimum
• Color space: RGB
• File size: Under 10MB
• Content: Must include book title and author name. No pricing, reviews, or promotional text.
• No blurriness: Images must be sharp and legible at thumbnail size (200 x 200 pixels)

Apple Books Requirements

Apple follows similar guidelines to ACX but has a few distinctions. Cover art must be exactly square, at least 2400 x 2400 pixels. Apple is stricter about image quality — blurry or pixelated covers are rejected automatically. Text must be legible at small sizes.

Spotify Audiobook Covers

Spotify requires square cover art at minimum 640 x 640 pixels, though 3000 x 3000 is recommended. Spotify displays covers at smaller sizes than other platforms, so legibility at thumbnail scale is critical. Avoid fine text or detailed illustrations that become muddy when shrunk.

Design Principles for Audio Covers

Audiobook covers work differently from ebook covers. They are almost always viewed at thumbnail size — smaller than a postage stamp on a phone screen. Design for that reality:

• Bold, large title text that is readable at 200 x 200 pixels
• High contrast between text and background
• Simple imagery — avoid busy photos or complex illustrations
• Consistent branding if you have a series
• Author name visible but secondary to the title

Can You Use Your Ebook Cover?

Yes, with modifications. Your ebook cover is likely designed for a vertical rectangle (roughly 6 x 9 ratio). Audiobook covers must be square. Simply cropping the top and bottom of your ebook cover usually looks terrible. Instead, redesign for the square format — keep the same visual style and branding, but restructure the layout.

Many designers offer an audiobook cover variant for $50 to $150 if you already have an ebook cover designed. Some AI design tools can generate audiobook covers that match your existing brand for free.

Common Rejection Reasons

• Cover image is not square
• Resolution below 2400 x 2400
• Title or author name not included on the cover
• Promotional text ("New York Times Bestseller", "50% Off") on the cover
• Blurry or pixelated at thumbnail size
• Copyright-infringing imagery
