Add Background-Size to Customizer
This plugin for WordPress adds a background-size controller to the Background Image section in the WordPress Customizer.
You can access the new controller by going to Appearance > Customize from the Dashboard, and clicking on the Background Image section.
Once you’ve added your custom background image, you can set your background-image size to: – „Cover“: As large as possible; fills entire view, with cropping. – „Contain“: As large as possible, without cropping; fits inside of view. – „100% width“: Width fits view perfectly, height may be smaller or larger than view (equivalent to css ‚100% auto‘). – „100% height“: Height fits view perfectly, width may be smaller or larger than view (equivalent to css ‚auto 100%‘). – „Inherit“: Sets background size to whatever parent element is set to (html, in this case). – „Custom“: Allows you to put in your own css to be applied in the section called „CSS for background-size (if ‚custom‘ selected).“

Notes
Notes: *The plugin works by adding styles to the body.custom-background class. If the default custom-background support has been disrupted, then this plugin will not work.
