Hi @softfully,
We’ll add a compact style for Article Rating in future releases.
At the moment you can make it compact using putting this CSS code in the Top Admin Bar > Customize > Additional CSS > Custom CSS Code textarea. Delete all caches and check, it should look like this:

#wpd-post-rating .wpd-rating-wrap { width: auto; }
#wpd-post-rating .wpd-rating-wrap .wpd-rating-data {width: auto!important; white-space: normal!important; text-align: center!important; display: block!important;}
#wpd-post-rating .wpd-rating-wrap .wpd-rating-value .wpdrv {font-size: 17px !important; line-height: 39px !important; padding-top: 0 !important;}
#wpd-post-rating .wpd-rating-wrap .wpd-rating-value .wpdrt { font-size: 10px !important; line-height: 14px !important;}
#wpd-post-rating .wpd-rating-wrap .wpd-rating-left { display: none!important;}
#wpd-post-rating .wpd-rating-wrap .wpd-rating-right {display: none!important;}
#wpd-post-rating .wpd-rating-wrap .wpd-rating-value { height: 40px!important; width: 40px!important; float: left!important; margin-right: 8px!important;}
#wpd-post-rating .wpd-rating-wrap .wpd-rating-title {width: auto!important; white-space: nowrap!important; word-break: normal!important; font-size: 14px!important; line-height: 46px!important; display: block!important; margin-top: 0!important; margin-bottom: 0!important; float: right!important; margin-left: 10px!important;}
#wpd-post-rating .wpd-rating-wrap .wpd-rating-value .wpdrc { font-size: 12px !important; line-height: 16px !important; display: none !important; padding-top: 5px !important;}
To remove the top and bottom spaces you can use this CSS Code:
#wpd-post-rating {
margin-top: 0px;
margin-bottom: 0px;
}
