# Thumbnail

The Thumbnail style setting lets you control how post images are displayed across your site. This option defines the **aspect ratio** used for post thumbnails in the feed, helping you match the layout to your content style and visual preferences.

The selected style is applied to the **homepage**, **archive pages**, and **related posts**, ensuring a consistent look throughout the site.
