The standard size of a podcast artwork is usually 3000 × 3000 pixels square. Apple Podcasts permits show covers with a resolution of 1400 x 1400 to 3000 x 3000 pixels if you submit your show through an RSS feed. The largest size is preferred since it makes it easier to display on other promotional spots all over the platform.

How can good podcast cover art help attract listeners?

A good podcast cover will help you appear at the top places of your listeners' phone searches for your podcast. It serves as a visual representation of your podcast and the message you want to convey. Additionally, one of the requirements for having a podcast featured on iTunes is having high-quality podcast cover art. Your podcast cover art is speaking to listeners long before they hear you speak because it conveys a powerful visual message.
