Podcast Cover Art: Sizes, Specs, and What Makes One Work
It has to clear a hard technical gate and still read at the size of a thumbnail. Get both, or your show does not list - or does not get tapped.
Your podcast cover is the one image the whole show rides on. It is the first thing - often the only thing - a listener sees in a directory of millions, shrunk to a thumbnail the size of a postage stamp. And unlike a blog cover, it sits behind hard gates: get the shape, format, or color space wrong and the directory rejects it, so the show never goes live. Two jobs, then - clear the spec, and still work at thumbnail size - and most cover art nails neither.
The one spec to remember
Make it 3000 x 3000 pixels, square, RGB, saved as JPEG. That single file satisfies Apple Podcasts, Spotify, YouTube Music, and every app that pulls from your feed. Design the master at 3000 and it stays sharp on 4K screens, TV apps, and car dashboards too.
| Platform | Pixel range (square) | Notes |
|---|---|---|
| Apple Podcasts | 1400 to 3000 px | PNG or JPG, RGB, no transparency |
| Spotify | 1400 to 3000 px | PNG, JPG, or TIF; up to 30MB; title and author on the art |
| One file for both | 3000 x 3000, RGB | export JPEG and it clears every app |
The gates that get shows rejected
A handful of these are not suggestions. Miss one and a platform rejects the art or refuses the upload - the dreaded “it won’t go live” with no obvious reason:
- Perfectly square (1:1). A 2999 x 3000 file is not square, and apps reject it. Crop to an exact square.
- No transparency. Apple rejects artwork with an alpha channel - flatten it onto a solid background before exporting.
- RGB, not CMYK. Export from a print-minded tool and you can ship the CMYK color space by accident; feeds want RGB, and CMYK renders wrong.
- A file size your host accepts. Caps vary - some hosts are as tight as 512KB, while Spotify allows up to 30MB - and a 3000-pixel PNG is enormous, so export JPEG, not PNG at 80 to 90 percent quality to keep it small.
None of these are design choices. They live in the export step, and they are the boring reasons a show stalls before it goes live.
It has to survive being a thumbnail
Here is the design trap: you make it at 3000 pixels on a big bright screen, but a listener sees it at maybe 55 pixels, in a scrolling grid, on a watch face, on a car dashboard. Detail vanishes; only the broad shape survives. So design for the small render, not the master file:
- A few big words, usually just the show name. Spotify actually requires the title and author to be on the art and legible, so a clear name is a platform rule, not just good taste. A tagline or episode number, though, is illegible at thumbnail size and only adds noise - the same case against crowding a cover with text.
- High contrast. Your cover competes in a wall of other covers; muddy mid-tones disappear, while a bold light-on-dark (or dark-on-light) holds.
- One focal point. A single strong element - a word, a face, a mark - reads at any size; a busy collage turns to mush.
- Heavy, legible type. Thin or decorative faces smear when shrunk; reach for a heavy, screen-built face.
The check is the one every cover should pass: shrink it to a thumbnail, glance once, and see if you still know whose show it is.
The mistakes that show up most
- Baking “Episode 47” or a guest name into the art - it changes weekly; the cover should not.
- A URL or social handle nobody can read at 55 pixels.
- Low-contrast text floating over a busy photo.
- A border or letterbox around the art - Spotify advises against it, and it only shrinks the part that has to read small.
- Exporting too small, then shipping a soft, upscaled and blurry cover.
- The wrong color space, or an oversized PNG that quietly fails the feed.
Make it in Lede
Lede has a Square (1:1) preset - or set a custom square canvas - and exports at up to 4x, which clears the 3000-pixel mark with room to spare. Set the show name in a heavy face, push the contrast, keep it to one idea, and export as JPEG so the file lands under the size cap. It is the same toolkit as a social-sized image, pointed at a square.
Podcast cover art is two problems wearing one square: a technical gate that decides whether your show lists at all, and a thumbnail that decides whether anyone taps it. Hit 3000 x 3000, square, RGB, a JPEG sized for your host, put one bold idea on it that survives being shrunk to a stamp, and you have cleared both.
