To check your entire signature, I basically screenshot your signature, from the first pixel, to the last, so in this case it would be from the top left corner of the first "Show Content" box, to the bottom dotted line. The dotted line widths don't count since that's not really something users can control anyway.

I put the screenshot in Photoshop, crop it, and then check the image size.
What I'd consider your signature is this:

And the size is this:

If you don't have a way to check your exact size, this should be a good reference point:
