When switching to our new PDF generator you may notice that the font size has increased.  To fix this, just follow the steps below.

Edit your theme

To edit your theme, go to Settings > PDF Themes > Select your current theme.  Your current theme is the one furthest left, to access and modify that simply click on it.

Change the Font Size

To change the font size go to Settings > PDF Themes > Select the current theme (furthest left) > The Basics > Change the font size using the pt drop down.  The smaller the number the smaller the font size.  When you're done, just press Save & Preview.  If required repeat this to make smaller or bigger as appropriate.
