Set custom image size for images upload to WordPress

Posted on: 22 June 2018     Posted by: Freesize Workroom

Set the image size by resizing the image proportionally (without distorting it):

add_image_size( 'custom-size', 220, 180 ); // 220 pixels wide by 180 pixels tall, soft proportional crop mode

Set the image size by cropping the image (not showing part of it):

add_image_size( 'custom-size', 220, 180, true ); // 220 pixels wide by 180 pixels tall, hard crop mode

Set the image size by cropping the image and defining a crop position:

add_image_size( 'custom-size', 220, 220, array( 'left', 'top' ) ); // Hard crop left top

When setting a crop position, the first value in the array is the x axis crop position, the second is the y axis crop position.

  • x_crop_position accepts ‘left’ ‘center’, or ‘right’.
  • y_crop_position accepts ‘top’, ‘center’, or ‘bottom’.

By default, these values default to ‘center’ when using hard crop mode.
