Increase height of gallery carousel

Hi guys, ask this previously with no response! Does anyone know the code to increase the standard height of a gallery carousel block on desktop? I have used the mobile code to decrease the height on mobile, which worked perfectly, but I essentially want to do the opposite on desktop, and just get a touch more height to the landscape images in the carousel when viewed on a widescreen monitor. 
 

The height is of course set to L/100% in the gallery block editor.

Any help is greatly appreciated!
