Image Size Cheat Sheet

Images in the WashU Web Theme require specific dimensions to display properly.

Featured Images

What is a featured image? If you’re not sure, read about featured images first.

Images Block

In addition to featured images, you’ll probably want to place images within the body of your content. This can be done using the image block.

Image size

For images that will appear within the content of a page or post, upload the largest size you have (maximum 16 MB) and let WordPress resize the image dimensions for the space where it’s displayed.

This gives you flexibility to use the same image in different ways throughout your site. For example, on one page you might place the image in the header of a card where it will show up small, and on another page or post you might use it as a featured image where it would display much larger.

Orientation and aspect ratio

Images that are horizontal, at least 760 pixels wide and have a 3:2 aspect ratio will display well in almost all settings throughout your site.

Just remember to observe the optimal aspect ratios listed above if you plan to use it as a featured image.


Feeling lucky? You can try uploading an image that’s larger than the recommended size and see how WordPress crops it.

Want more control? Crop the image to the recommended aspect ratio before uploading it to your site. We strongly advise against using the image editor in WordPress.
