What size toploader should I need for my trading card
This will be a short and concise guide about the trading card thickness and how to find the right fit topload card holder or toploader for short for your trading card.
I will start with my experience. I am the only person and acquaintance I know and knew when I started to collect hockey trading cards so I had to learn everything the hard way. At the start, around 2010, I was getting my single hockey cards from internet marketplaces which was pretty much the only option around then so all I have ever seen was just the photo of a card before I received it in hands. Of course using logic you can figure out that Jersey card should be thicker than any other card but imagine my shocking surprise when I received in hand my first Upper Deck The Cup rookie autograph patch card. I gathered a couple of The Cup cards in years and those card toploaders which I received my cards in was either a little to thick so card is almost falling out and some was even a little bit too narrow. So I needed a various thickness toploaders and as I was searching where to buy them I noticed that even the toploader manufacturers had various thickness toploaders and I didn't knew which toploader will be the right fit for my cards.
Trading card thickness is measured in point stock system (PT) where 1000 points are 1" or 2,54cm or 25,4mm and one regular card is 20 PT thick.
I know it sounds very complex and confusing right now but follow me. The best way for me to measure trading card thickness is with the trading cards itself. I know, I know it doesn't sound very precise but trust me it's just simple math:
1 regular trading card is 20 PT thick
3 regular trading cards will be 60 PT thick
5 regular trading cards will be 100 PT thick
And if your card still doesn't fit your toploader don't worry I have added the toploader thickness standards by supplies manufacturers BCW and Ultra PRO down bellow.
Convert millimeters in point stock system (mm to PT)
When I started to learn and practice PT measurements I measured my cards with a ruler or caliper and converted the millimeter measurement into the point stock system with the table which I found somewhere in the web in 2012:
1 mm - 39 PT
1,4 mm - 55 PT
1,9 mm - 75 PT
2,54 mm - 100 PT
2,75 mm - 108 PT
3,5 mm - 138 PT
5 mm - 197 PT
7 mm - 275 PT
10 mm - 394 PT
