How Do I Manage Image Size in WordPress?

In WordPress, you can manage image size by using the Media Library. To open the Media Library, go to the Administration Area and click on Media. You can then select an image to view its properties. On the Image Size tab, you can specify the image’s Width and Height in pixels.

You can also specify the image’s Medium or Large size. WordPress will use these values to resize any images that are used in your blog posts or pages. You can also specify a custom size by entering a width and height in pixels.
