WordPress lets you change the default image sizes for your site's thumbnails, medium images, and large images. These default sizes apply to every image you upload to your site unless you select to upload images in full size. This quick tutorial shows how to change WordPress image sizes if the default dimensions don't suit your site's theme.

How to Change the Default WordPress Image Sizes
Changing the default WordPress image sizes lets you upload and publish images that fit your WordPress site content better. Follow the steps below to edit the default image sizes for your site:
- Log in to your WordPress site.
- Hover over "Settings" in the menu on the left, then click "Media."
- The default image sizes will be on the Media Settings page.
- Use the up and down buttons or change the preferred sizes in each dimension field.
- If you only want to set the max width or height, but not both, set the width field to the value you want, and the height field to "0" (or vice-versa)
- Click "Save Changes" at the bottom of the Media Settings page.
Important note: if you only want to change the dimensions of specific images uploaded to your site, you can crop them individually in "Media -> Library." This avoids unintentional resizing of other uploaded images after you set new default image sizes.
Good to know: You can make good use of the best sites to get royalty-free images for your WordPress site.
