Updating your profile image on Tidal is easy, keep in mind, however, that this can only be done on request through Beatrising. You can set up a Tidal artist page by creating a ticket and making sure your sizes match the ones below to ensure your profile stays looking the best it possibly can.
Tidal Image Sizes:
• Preferably an artist photo (1080 x 720 pixels) with group members close together.
• It can be square; vertical images will have to be cropped to a square anyway.
