What Are the Default WordPress Image Sizes?

There are a few default image sizes in WordPress, depending on the theme you are using. If you are using a free theme, then the default image size is likely either 320 or 480 pixels wide by 240 or 480 pixels high.

If you are using a paid theme, then the default image size may be different, but is usually a bit larger. For example, the default image size for the Twenty Thirteen theme is 1600 pixels wide by 1066 pixels high.

When you upload an image to your WordPress blog, you can specify the size in pixels that the image will be stored as. For example, if you upload an image that is 320 pixels wide by 240 pixels high, WordPress will store the image as a 320 pixel wide by 240 pixel high image.

You can also specify that WordPress should store the image as a thumbnail, which is a smaller version of the image that is stored on your blog. If you specify that WordPress should store the image as a thumbnail, then WordPress will create a 200 pixel wide by 100 pixel high thumbnail for the image.

If you want to change the default image size for your blog, you can do so by editing the wp-config.php file.

To change the default image size, you will need to locate the line that says “default_images_size” and change the value to the size that you want the default image size to be. For example, if you want the default image size to be 1600 pixels wide by 1066 pixels high, you would change the value to “default_images_size => ‘1600×1066′”.
