SVG file opens up huge in Cricut design space software

Hello,

I create SVG cutting files for use with Silhouette, Cricut etc.  I have had a few customers complain the the file size is huge when trying to open up in Cricut design space.  I export it at only 4 inches or so, but some say it's as big as over 100 inches. and crashes the program.

Any ideas on why this happens and how to fix?
