What Size Toploader Do I Need? 35pt to 360pt Explained
Every toploader is the same 3″ x 4″ on the outside. The number — 35pt, 55pt, 130pt — is not the size of the holder. It is how deep the slot inside is, measured in thousandths of an inch. A 35pt toploader takes a card up to 0.035″ thick.
That is why two toploaders can look identical on a shelf and only one of them fits your card.
35pt: the one you want almost always
A standard trading card — Pokémon, Lorcana, One Piece, Magic, a modern sports base card — sits comfortably inside 35pt with room for a penny sleeve. If you are buying one size and sticking to it, this is the size. It is what the overwhelming majority of cards need, and it is what we stock: 35pt toploaders, 100 per pack.
Buying thicker “just in case” is a mistake. A standard card rattling around in a 100pt toploader slides, and a sliding card is a scratched card. The fit is part of the protection.
When you need thicker
You need a deeper toploader when the card itself is thicker than normal stock. In practice that means:
- 55–79pt — thin relics, some autographed cards, thicker premium stock
- 100–140pt — patch cards, dual memorabilia, multi-layer relics
- 160–240pt — heavy manufactured relics, medallion cards
- 300pt and up — booklet cards that open out
These are mostly a sports card problem. If you collect TCGs exclusively, you may never need anything but 35pt.
The coin trick
If you are holding a card and do not know what it needs, compare it to coins. A card about as thick as a 5p is standard and takes 35pt. About a 10p, you are into 55pt territory. Two 10ps stacked, think 100pt and up.
It is rough, but it is quicker than a caliper and it stops the mistake that matters — trying to force a thick card into a 35pt holder.
Never force one
If a card does not slide in with light pressure, it is the wrong toploader. Pushing a card into a slot that is too shallow bends the corners on the way in and does it again on the way out. More cards are damaged by the wrong size toploader than by no toploader at all.
The same goes for getting one out. Squeeze the sides of the toploader gently to widen the mouth rather than pinching the card and pulling.
Toploader or magnetic case?
A toploader is the working option — cheap enough to use in quantity, right for posting, storing and taking to a show. A magnetic card case is the display option: thicker, clearer, closes properly, and looks like something you would put on a shelf. The rule most collectors land on is toploaders for the many, magnetic cases for the few.
And once a card is graded, neither applies — the slab does that job, and what needs protecting is the case around it.
Keep a record while you are at it
If you are sorting cards into toploaders, you are already handling the collection — that is the easiest moment to record it. SlabShield Vault is free, tracks what everything is worth, and will tell you which cards you are missing from a set you have started.
