Podcast Cover Art Size: 3000 × 3000, Designed to Be Seen at 55 Pixels

Podcast cover art has a strange requirement: it is submitted enormous and consumed tiny. You upload a 3000-pixel square, and the place where it actually competes for attention is a scrolling list on a phone, where it occupies roughly 55 pixels. Designing for the upload size instead of the display size is the mistake that makes most podcast artwork invisible.

The Specification

• 3000 × 3000 pixels — submit this. Both Apple Podcasts and Spotify accept it, and it is the maximum, so nothing is lost later.
• Minimum 1400 × 1400. Below this your show is rejected outright by Apple.
• Square. Not nearly square. A rectangle is rejected or cropped badly.
• JPEG or PNG, in the RGB colour space.
• Under 512 KB is a safe target. Some directories are stricter than others and a large file fails ingestion at the fussiest one.

The RGB requirement deserves its own note, because it causes rejections that look inexplicable. An image exported from print design software may be in CMYK — the colour mode for ink, not screens. The file opens fine on your computer and is refused by the directory. If a submission is rejected with no clear reason, check the colour mode first.

The 55-Pixel Problem

Open a podcast app and look at the list. Every show is a small square, a few millimetres across, and yours has to be distinguishable from thirty others at that size while someone scrolls past.

This governs every design decision:

• Two or three words at most. A long title becomes grey texture. If the show name will not fit legibly, use a shortened version or an abbreviation in the art.
• Enormous type. Far larger than feels reasonable at 3000 pixels. Set the text, then view the whole image at 55 pixels wide and see whether you can read it.
• High contrast. Mid-tone text on a mid-tone background disappears entirely.
• One focal element. A face, a symbol, a letterform — not a scene with several things in it.
• No thin lines, no fine detail, no gradients. All three become mush.

The reliable test costs nothing: export the finished art, scale a copy to 55 pixels, and put it beside screenshots of other podcasts in the same category. If yours is the one your eye slides past, it is not finished.

Why the Title Belongs in the Image

This is where podcast art differs from most other platform images, and it is worth stating because the usual advice points the other way.

With a link preview or a social post, the title appears as real text beside the image, so repeating it inside the picture wastes space. Podcast art is different: it shows up in places where no text accompanies it at all — a car’s dashboard display, a phone’s lock screen during playback, a watch face, a smart speaker’s app. In those moments the artwork is the only identifier the listener has.

So the show name should be in the art. Short, large, and legible — which is exactly why a long name is a liability from the first day you choose it.

What Will Get You Rejected

Apple in particular is strict, and these are the common causes:

• Apple, Spotify or other platform logos, or the word “podcast” written as a brand mark alongside them. You may not imply endorsement.
• URLs, social handles or email addresses. Unreadable at display size anyway, and against the guidelines.
• “New episode every Tuesday” or episode numbers. The art is for the show, not for an announcement; anything time-bound goes stale.
• Explicit-content markings you add yourself. There is a metadata flag for that; the directory draws its own badge.
• Imagery you do not have rights to, including stock photos used outside their licence and anything resembling another show’s branding.

Changing It Later

Directories cache artwork aggressively. After you update the image in your hosting provider and the feed refreshes, Apple and Spotify may take several days to show the new art, and different apps will update at different times — so for a while your show appears with two different covers depending on where someone looks.

Plan rebrands with that lag in mind, and do not conclude the update failed after a day. Changing the image filename as well as its contents helps, for the same reason it helps with any cached image.

Episode Art

Individual episodes can carry their own artwork, with the same 3000 × 3000 requirements. It is optional and most shows skip it — reasonably, since it multiplies the production work. It earns its cost for interview shows, where a guest’s face is a genuine reason to click, and for series within a feed.

When you do use it, keep the show’s visual identity recognisable. Episode art that looks unrelated to the cover breaks the thread in a listener’s library.

Quick Reference

• 3000 × 3000 square, JPEG or PNG, RGB not CMYK, under 512 KB
• Minimum 1400 × 1400 or Apple rejects it
• Design for 55 pixels — check it at that size before submitting
• Show name in the art, two or three words, very large
• No platform logos, URLs, social handles or episode numbers
• Allow several days for a changed cover to propagate
