You did it! You finished editing your video or crafting the perfect post. Now comes the cherry on top: a perfect thumbnail.

A thumbnail is an image that is displayed as a preview to your real content. Thumbnails can convince someone to click on your content, drawing their attention from other content in the feed or grid. Thumbnails can also help you maintain a certain brand or aesthetic on your social media channels. You can post lower resolution or raw videos without disrupting the overall look and feel of your feed.

Depending on the platform and content type, thumbnails can vary in size. We wanted to assemble an ultimate guide to thumbnail dimensions!

You can apply any of these dimensions to your own thumbnail designs by using Kapwing Studio, a free online tool for creators.
