Increase logo size?

Hello!

I’m trying to increase the size of the logo inside the header.

I used the header hook to get the text in there next to it, but now I want to make the actual logo image bigger.

If I do it via css, the image just gets blurry, and if you look in inspector at the tag, it has specific height and width as html tags, and I have no idea how to modify that. Thoughts?

Thank you in advance!
