Our Tumblr Image Size Guide
For your profile
The presentation of your Tumblr profile has a major impact on how other users perceive your content. To start, we recommend using a profile picture of 128×128 pixels.
This size is ideal for displaying your image clearly while keeping it small enough to fit perfectly in the avatar space. You should also consider your Tumblr cover photo, which should ideally measure 3000×1055 pixels.
This wide format provides plenty of space for a striking image that stands out and complements your profile picture.

For your posts
Regarding the images you share on Tumblr, keep a few key dimensions in mind to ensure optimal display in the Tumblr feed.
Photos are generally displayed at a minimum of 540×810 pixels, but can go up to 1280×1920 pixels for high-resolution images. This ensures even the subtlest details of your images are captured clearly and not lost to compression or resizing.

For your animated GIFs
Finally, if you plan to share GIFs on Tumblr, note that the platform recommends a maximum width of 500 px for animated images. Also ensure your GIFs do not exceed 1 MB to avoid slow loading or display issues.
Also, if you plan to post a photo on an audio post, the recommended size is 169×169 pixels to fit the dedicated space perfectly.
