Stand up.
Notice the two dents left in the foil from your ischial tuberosities. Mark their centers with a marker.
Measure the distance between the marks.
Another option - just go by your LBS and wearing your riding shorts and get your sit bones measured acturately on this device.
Worked perfect for for my wife and I. Then we had a professional bike fit, money totally well spent.
I did not want to waste $$$ and then own a box of saddles that never worked.
FWIW...
