I use SVGs, which aren't supported directly – so maybe this isn't a question for you? See screenshot here:

The Frame logo to the left is an SVG - Laygridder treats this file as if it's 0,1% high. It makes it more difficult to handle SVGs.
I use this plugin to get SVG support: https://wordpress.org/plugins/scalable-vector-graphics-svg/
Should I rather use something else?
