EA Mattes pads - what size do I need?

How do I determine what size EA Mattes saddle pad I need? 

1. Using a measuring tape measure the distance, following the contour of the saddle at the top of the channel, between an imaginery line at the front (see picture below).
2. Add a minimum of 6cm.
3. The measurement you have just taken is the MINIMUM pad length required for your saddle.  Choose the appropriate size from this guide:

• small=47cm
• medium=54cm
• large=58cm
• extra large=62cm
