Okay Jeanie this is what worked for us:
1. Save template to desktop as PDF.
2. Click to open and it will be in Preview.
3. Go to Preview on top left corner of screen and click on 'preferences' - a PDF box will appear.
4. Click the button to change 'Initial document scale to 'use scale of 100%' (not size to fit which is directly under it)
5. You also need to define 100% scale as 'size on screen equals size on printout'.
There are a few other boxes but we didn't need to tick any of those.
And that was all we had to do to get the right size template. I hope this is of use.
Rita.
