If you are preparing a template to route out a circle for instance or a square as a simple example.
If the circle required is say 100mm then the template required will be 100mm PLUS the difference between the Guide and Cutter.
Routing a square would be exactly the same The square template would be 100mm square PLUS the difference between the guide and the cutter.
Try this as an example Make a circular template say 60mm in diameter With a 30mm guide and a 10mm cutter rout a hole in your material This could be only 1mm deep to take a thin weneer.
With the same template rout an insert from 1mm material this time using a 16mm Guide with a 4mm cutter and hey presto you will have a perfect insert.

Enclosed is an introduction to the use of Template guides taken from my collection of routing techniques.
