Why should the guide title picture be 195x195?

[[?]legit]

Steam recommends that the title image of a guide should be at least 195 x 195 px.

As far as I know, the largest size the title image is shown at is 160 x 160, that's when it's in the "Favorite Guide Showcase".

Is there any scenario where the guide image would be shown at 195 x 195? If not, I wonder why it's recommended to upload in such big dimensions.🤔

Could be BPM has a bigger size or they put it in case they do something that may fit for a bigger size
