measuring stamps

Lets say the desc. says 21x36mm for the stamp "size".
Do you measure from outside of perf to the outsideof perf on the opposite
side of stamp? Or do you measure the printed part of the stamp? Some stamps
have no border so how do you measure it?

It's the printed part of the stamp. If the design doesn't have a
printed rectangular border, use an imaginary rectangle which just
encloses all the print.

Often it's simpler to lay one stamp on top of the other rather than
measure. If you have a damaged stamp of the same issue, cut off the
corners diagonally to make it easier to see.

Of course, if there is no margin, you will not get the size in the description!
When the design crosses the perforations it is called 'bleeding' (or possibly
a perforation shift!!)

Chris, I don't buy your method of cutting a damaged stamp to use as a
guide. Some stamps have 1/2mm increments...there ain't no way you can
cut to 1/2mm limit. I can't even get 1mm with any accuracy at all. The
ideal thing would be to have a set of machine cut guages of all sizes.

I think you have misunderstood.

If you cut a known stamp, then when held against the stamp under
investigation any difference in size is obvious.

This is a standard method for distinguishing the various types of
GNR overprint (Italian Social Republic) and AMG-FTT overprints
(Trieste Zone A)

In the case of stamp sizes, such as some of the George V photogravure issues
of GB, the schilling values of the 1929 issue of Austria, and the Imperiale
issues of Italy, then cutting the corners enables a comparison of both the
vertical and horizontal dimensions at the same time. 1/2 mm changes are easy to
detect in this way.

In a similar way, the quickest way of checking perforation varieties is to hold
the edge of a known perf stamp against the edge of the one under investigation.

I was looking for a scarce perf variety once when I had forgotten to bring my
perforation gauge; the two stamps in the dealer's stockbook clearly had
different perfs so I bought both for 10 pence, when I knew that one of the two was
catalogued at 500 euros.

generally it is the measurement of the printed part of the stamps but
how I don't know all catalogues in the world, I cannot affirm it is
always so (it is so for Yvert, Facit, Michel).
