A finished cover getting rejected by a distributor, or looking soft and pixelated on a streaming thumbnail, is almost always a sizing problem — not a quality problem. Here are the exact specs to confirm before a single pixel gets rendered.
Streaming Platforms (Spotify, Apple Music, and Most DSPs)
Using anything smaller than 3000px risks your cover looking soft when a platform displays it at a larger size — for example, on an album detail page or a "now playing" full-screen view.
Vinyl Packaging
Vinyl is the one format where getting the file mode wrong (RGB instead of CMYK) causes a visible color shift between what you approved on screen and what prints — always confirm CMYK conversion before sending to a pressing plant.
CD Packaging
Quick Reference Table
| Format | Dimensions | Resolution | Color Mode |
|---|---|---|---|
| Streaming (Spotify/Apple Music) | 3000 x 3000px | 72–300 DPI | RGB |
| Vinyl 12" sleeve | 12.5 x 12.5 in (with bleed) | 300 DPI | CMYK |
| CD front cover | 4.72 x 4.72 in (with bleed) | 300 DPI | CMYK |
| Social media thumbnail crop | 1080 x 1080px | 72 DPI | RGB |
Why This Matters Before You Commission, Not After
The single biggest mistake is deciding on final format after a cover is already finished. Print (CMYK) and digital (RGB) color don't translate 1:1 — a color that looks vivid on screen can shift when converted to CMYK for print. If there's any chance a cover will go to vinyl or CD, say so at the brief stage so the artist can work in the right color mode from the start, rather than converting after the fact.
A structured commission process — like the one used for album, manga, and illustration work here — will typically ask about final format upfront for exactly this reason.
Manga and Book Cover Specs (For Comparison)
Manga and book covers follow a different logic since they're rarely square:
Final Thoughts
Getting dimensions right isn't the creative part of a commission, but it's the part that determines whether the creative work actually holds up across every place it needs to appear — a streaming thumbnail, a printed sleeve, a social post. Confirm the final use case before work starts, and the rest of the process gets a lot simpler.
