In this article you will learn how to calculate the trading card thickness, from millimeters (mm) to points (PT) and choose the suitable toploader.
The same way every card collectors collection grows, the demand for new toploaders grows along with it. If you're not a professional or a trader with decades of gained experience, it's really hard to determine the cards' thickness only by it's appearance. Talking from my experience it wasn't easy to collect the information, because it was deficient. Not to mention that the point (PT) system was (and still is) like rocket science for me.

Trading card thickness is measured in points (PT)
Trading card thickness is measured in point system (abbreviation PT). One regular card is 20 PT. The biggest issue for me was to understand what the PT system is, because I live in Europe and I'm used to the metric system. Of course, you can put together various cards and calculate the outcome, but that wasn't for me. The easiest way for me (and maybe it could be for you too) was to just measure card thickness with a ruler and transform metric systems millimeters into points (PT):
