Item thumbmail

Hi all
Theme forest says my html template(item) thumbnail must be 80 x 80px…

But when I look at the published template thumbnails they are not 80x80…

This very confusing…80x80 images does even look good looks ugly when I resize it…can barely read text in the image.

Thumbnails definitely are 80x80px, are you sure you are not confusing thumbnails with preview images?
