Accurately Grade and Measure Stamp Perforations

The Stamp Analyser digitally measures the stamp perforations, the stamp frame and the balance among the four margins (centering) to determine the preliminary grade of the stamp.You no longer need a perforation gauge or reliance on the seller’s definition of stamp centering. The Stamp Analyser provides this information based on accurate measurement; no more guess work. All you need to do is to provide a good scan or a good photograph of the stamp and the Stamp Analyser does the rest.

Optionally, you can add the stamp Soundness and Eye Appeal components to obtain the final grade. The Soundness and Eye Appeal components are based on the PSE Grading Guide.

The Stamp Analyser user interface has been designed to be intuitive and simple. On the Mac, you simply drag and drop your stamp image into the Stamp Analyser. On the iPad and iPhone, you can either take a photo of the stamp or select it from the photo library.

A stamp collector’s must have tool!


As a stamp collector for over 55 years, one of my least favorite things to do is trying to figure out perforation sizes. And, as I’ve gotten older, my eyes just aren’t what they used to be. I grew up with the standard perforation gauges as well as the newer precision multi-gauge. None of those are as easy to use as the Stamp Analyser! It is fast and accurate and the developer is very quick to respond to inquiries and suggestions - thanks Rashid! I also like that it grades your stamp based on the PSE grading guide. So, for about the price of 10 US first class postage stamps, you can let your Mac be your perf slave. ;)

Stamp Analyser ~ My choice for all my grading needs!

VERY happy agent

Wonderful piece of software!
Easy to use and very quick with the "Drag & Drop" feature.
I've used other 'grading' software for postage stamps and this is 'hands down' the best. Well worth the cost of the software.
If you're into the philatelic hobby, and grading your stamps is important to you . . . BUY THIS! You'll be glad you did!

This is a wonderful tool for grading your stamps


This is really a neat piece of software and it works like a charm!
All you have to do is to move a scanned image of the stamp into the window and the program does the rest.
It lines everything up and grades the stamp quickly.
If you collect stamps you should buy this!
