I am creating a large map, therefore the legend needs to be large. I have made the text large, but I can't seem to figure out how to make the polygon symbols larger. I have included a picture for context.
If anyone knows how to help that would be amazing!!
Thank You:))
It goes off of the size you have set in the map. I would create a copy of that layer and use it solely for symbology in your legend.
What if its a polygon layer?
legend patch
Change the arrangement and sizing of patches, labels, and descriptions.

@aduyvesteyn Dan is correct. You'll want to click on your legend item in the layout and then look at patch width and height!
