Sizing thumbnails popular post widget

I am looking for a few pointers on how to size the thumbnails when using the popular posts sidebar widget. The popular posts widget automaticallly pulls my featured image from the posts but the sizing seems to be off. Any help would be greatly appreciated. See website for reference: https://stateyourdestination.com/

Hello there,

It uses thumbnail size where you can change it from Dashboard > Settings > Media.

Thank you! I greatly appreciate your help. Do you have a recommended size in pixels to set the thumbnails? Also, this particular widget chooses the most recent post and adds it as a popular post. Is there a way to choose a specific post and make it stick instead of defaulting to most recent?

Hello there,

For that kind of purpose, try this plugin:
