Description
Both attributes are required in the sense that both parameters must have a value, but are optional in that if you set them to false or null, then they will not be added to the returned string.
You can set the value using a string, but it will only take numeric values. If you wish to put ‘px’ after the numbers, then it will be stripped out of the return.
Parameters
- $width
-
(int|string) (Required) Image width in pixels.
- $height
-
(int|string) (Required) Image height in pixels.
Return
(string) HTML attributes for width and, or height.

File: wp-includes/media.php

if ( $width ) {
$out .= 'width="' . intval( $width ) . '" ';
}
if ( $height ) {
$out .= 'height="' . intval( $height ) . '" ';
}
return $out;
