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. Not only can thumbnails convince someone to click on your content, they can also help you maintain a certain brand or ~aesthetic~ on your social media channels.
The thing is, depending on the platform and content type, thumbnails can vary in size. Let this article be your ultimate guide to thumbnail dimensions!
(Don't forget! You can apply any of these dimensions to your own thumbnail designs by using Kapwing Studio, a free online tool for creators.)
