Can I simply shrink a character for a map?

I just bought the Top Down City content. It includes a map, where if you are using the default 1st shooter character, you are a bit too big compared the the houses and other things on the map. What is the safest way to match the size without messing anything up? Can I just shrink the character in the main editor, or do I select everything in the map and make it larger? Thanks!

You could do both, but I would shrink the character rather in the character Blueprint.

I guess it comes down to doing what works for you in your situation.

Thanks yeah, I just wanted to avoid any unforeseen consequences like collision issues, etc.

That is why it is better to shrink on Character Blueprint … because your collision capsule needs to be resized with your model and that will handle the collision for you.
