How do you measure the width of a straight razor?

If you are selling a razor, it is often advantageous to measure the width from the top of the spine to the razor's edge.

My view is that you should measure from the razors edge to the edge of the spine bevel nearest to the edge.

I think it is important to try and agree on the method we should adopt to standardize the process.

I think it is important so that razors that are clearly undersize 5/8" are not advertised as 5/8".
