The maps I create have mandated scales and I try to get them to fit as often as possible onto standard page sizes to reduce printing costs. Legends, however, have become the bane of my existence in ArcPro because the different spacing options all appear to leave large chasms of unused space between items

I've tried fruitlessly to mess around with the various spacing options looking for the cause of the extra room, here is a the spacing settings for the above legend

Grateful for any tips, tricks or advice!
