SVG height and width

I am using custom svg’s (font Awesome) in my headline text. The output seems to be ‘fatter’ then what is shown on Font Awesome.

I even used the new copy from the SVG optimizer

The current GB Icons expect the SVG to be Square.
So they can be distorted and may require CSS to change that.
But first try changing the SVG HTML viewbox to be square.
In the HTML you should see something like:

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 384 512">

You can change it to:

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512">
