I found a wonderful SC measuring tool in the file section on the Organic Beekeepers Yahoo Groups list. Here's what it looks like:
You print it out and cover it with clear contact paper so it can last through the gunk of inspections.
I carried it in my pocket out to the hives and then I held it up to the rows of cells to measure the cell sizes. I didn't have time for much - my daughters and significant others and spouses were coming to dinner - but I did measure the cells on the side of a brood frame in my weak hive that has made it through the winter and has had no foundation given to them this year but SC starter strips - and the cells on the EDGE of the frame measured 5.2
I whooped - the girls are getting it!
