Size of cover image for TV Series

What is the size (or aspect ratio) for TV series folders.

I have a TV series that doesn’t automatically get an image, I’ve tried using a custom image which gets cropped, what size should it be so that it doesn’t get cropped?

Thanks

The recommended sizes are 1000 x 1500 for poster images, or 1920 x 1080 for landscape.

Smaller sizes will work too, though just be sure to maintain those aspect ratios if you want to avoid cropping.

Thanks it looks great now.
