Enlarge Spotlight right side preview pane?

I use Spotlight quite a bit for finding text in files, and most of the time it works flawlessly (Sierra 10.12.5, 27” iMac). But is there any way to enlarge Spotlight´s right hand preview pane, which shows text a bit small for my eyes? Like here:

I know I can get to any file quickly in the Finder and then tap the spacebar, which gives me an easily legible, proper size view, but it would be nice and more convenient if this worked directly in Spotlight too. Is this possible? Thanks in advance for any help offered! Cheers, Ian.
