Quick answer
CardSpicy takes a sleeve size from the thickness it is rated for rather than from the card it is sold beside, because the number on the pack — 35 PT, 130 PT — describes the space a card needs, not the card.
Every sleeve and holder in this hobby is sold by a number measured in points. That number does not describe the card. It describes the space the card needs — and the gap between those two things is the reason so many collectors buy the wrong size.
Buy a pack of sleeves and the front carries a figure like 35 PT or 130 PT. It looks like a size. It reads like a size. It is not a size at all — it is a thickness, expressed in a printer’s unit older than the hobby itself, and it describes an opening rather than an object.
That single confusion runs through almost every sizing question new collectors ask: why a 35 PT holder feels loose on a card that is nowhere near 35 PT thick, why the sleeve and the card seem to be measured on different scales, and why the answer to “which size do I need” is always a slightly larger number than seems right.
This page is the reference itself — the unit, the standard sizes, and how to pick one. For how the layers work together rather than how they are measured, the three-layer protection guide is the companion piece, and the notched-sleeve article covers the corner-shape question that sits next to this one.
What “PT” actually stands for
PT is short for point, and one point is one thousandth of an inch — 0.001 in, or 0.0254 mm.[1][2] It is a printing-trade unit, used for paper stock long before anyone was sliding trading cards into plastic, and the hobby inherited it wholesale.
The consequence is that the number on the pack is a measured thickness, not a capacity. A 35 PT holder has an interior opening 0.035 inch thick. A 130 PT holder has one 0.130 inch thick. Converting the whole standard range:
| Points | Inches | Millimetres |
|---|---|---|
| 35 PT | 0.035 in | 0.89 mm |
| 55 PT | 0.055 in | 1.40 mm |
| 75 PT | 0.075 in | 1.91 mm |
| 100 PT | 0.100 in | 2.54 mm |
| 130 PT | 0.130 in | 3.30 mm |
| 180 PT | 0.180 in | 4.57 mm |
| 260 PT | 0.260 in | 6.60 mm |
| 360 PT | 0.360 in | 9.14 mm |
Two things follow from that table, and both are useful. First, the steps are not even — the range jumps from 0.89 mm to 4.57 mm in five steps and then more than doubles again before it stops. Second, the scale is not a ranking. A 360 PT holder is not a better version of a 35 PT holder; it is a holder for a thicker object, and putting a standard card in one would leave it sliding around in more than eight millimetres of empty space.
What each standard size is for
In practice a handful of the eight sizes covers almost everything a Pokémon collector owns. The card grid below is the practical summary; the sizes that matter least to a TCG collection are the ones at the thick end, which exist for sports memorabilia.
Why 35 PT is the size nearly everyone buys
The number that surprises people first is this: a standard Pokémon card is roughly 12 PT thick, well under half of the smallest opening sold.[2][3] So why is 35 PT the default?
Because the opening is not sized for a bare card. It is sized for a bare card plus the sleeve that will go around it, with enough clearance left that the card slides in without being forced. A collector who measures only the card, buys a holder to match, and then tries to insert a sleeved card has discovered the gap the hard way.
That is the whole logic of the default. Sleeve a card and you have added material, and material has thickness. A card that measured 12 PT on its own is closer to 30 PT once a 50 µm sleeve is wrapped around it, which is why 35 PT is the opening that fits the arrangement nearly everyone is actually making. Penny sleeves sized for standard 63.5 × 88.9 mm cards are the layer underneath that number.
How thick is a Pokémon card, really?
Card thickness is not printed on the card and not advertised by the set, which is why a chart by card type is more useful than an exact figure. The ranges below are the ones the hobby supply trade uses; treat them as bands rather than measurements, and size up when a card sits near a boundary.[3][4]
| Card type | Typical thickness | Opening that clears it |
|---|---|---|
| Pokémon TCG — all rarities, base through secret rare | about 12 PT | 35 PT |
| Standard card inside one penny sleeve | about 30 PT | 35 PT |
| Two thin cards, or one card double-sleeved | about 55 PT | 55–75 PT |
| Japanese-size card (59 × 86 mm, e.g. Yu-Gi-Oh!) | about 22 PT | 35 PT — fits, but sits loose on the sides |
| Relic, jersey and patch cards | 75–180 PT | 100–180 PT |
| Booklets and folded cards | 260 PT and up | 260–360 PT |
Note the Yu-Gi-Oh! row, because it is a different problem wearing the same clothes. Japanese-size cards are shorter and narrower than standard ones, so the thickness is not the issue — a 35 PT opening accepts them easily, and they still move around inside a 63.5 mm wide sleeve. Thickness decides which PT you need; it does not decide whether the card fits side to side.
Sleeves carry two numbers, not one
This is where the confusion compounds. A sleeve is not specified by thickness alone, and the millimetre figures on a sleeve listing are answering a different question from the PT figure next to them.
| Product | Number one | Number two |
|---|---|---|
| Sleeve | PT — the card thickness it is rated for | mm — the outside width and height of the sleeve itself |
| Rigid holder | PT — the opening thickness | Footprint — almost always 3 × 4 inch (76 × 102 mm), the same at every PT |
A sleeve’s millimetre size has to be larger than the card in both directions, because the film has to fold around the edges without gripping them. That is why the sleeve range moves outward as it gets thicker: the 35 PT sleeve is 66 × 91 mm and the 360 PT sleeve is 76.5 × 98 mm, a centimetre wider to match the centimetre of extra material the thicker cards carry. CardSpicy’s penny sleeve range is listed across six options from 35 PT to 360 PT, all at the same price per hundred.
A rigid holder behaves the opposite way. The footprint does not change with the PT — a 35 PT holder and a 360 PT holder are both 3 × 4 inch on the outside, and it is only the interior that thickens. Our holders run eight options from 35 PT to 360 PT, in two versions that differ only in colour.
What the wrong size actually does
There are two failure directions, and they are not symmetrical. Oversizing is annoying. Undersizing damages.
Too tight. The card meets resistance on the way in. In a sleeve, the film has nowhere to go and folds under the card, creasing the surface or catching a corner. In a rigid holder, an oversized card bows and the pressure lands on the two corners that go in first — the exact corners a grader inspects first. The rule the hobby repeats without exception: never force a card into a holder. If it meets resistance, size up.[1][3] The cost of the wrong-size holder is a few cents; the cost of a creased corner is the card.
Too loose. The card shifts inside its sleeve, corner against film, every time the stack moves; the loose edges of the sleeve catch and bend; and the gap admits dust, which is abrasive once the card starts moving against it. A single size step up is usually harmless. Two or three steps up turns the holder into a display case, which is a different product with a different job — the damage guide sets out why grit inside a sleeve is one of the more common sources of surface scratches.
How to check a card without a caliper
Card thickness gauges exist, and a micrometer settles the question outright, but neither is necessary for a normal collection. Three cheaper tests get you to the right size:
- Check the set’s own product info first. Modern sets publish card counts and pack contents; if the card came out of a product that also lists card stock, that figure is more reliable than any estimate.
- Use the holder it arrived in. A card that shipped inside a toploader has already been sized for you. Read its PT off the pack or the listing, and reuse that number.
- Test the slide, not the measure. Put the card in the sleeve or holder and let go while holding the opening closed. If it drops in and out under its own weight, the size is workable. If it needs to be pushed, go up a step. If it rattles when you tilt it, go down a step — unless the card is valuable, in which case the looseness is the lesser problem and a second layer is the answer.
Which size to buy
For a Pokémon collection, three of the eight options cover essentially everything, and one of them covers most of it.
| What you are protecting | Thickness to clear | Sleeve | Rigid holder |
|---|---|---|---|
| A raw card, handled often | 12 PT | 35 PT | 35 PT |
| A raw card, sleeved then holdered | about 30 PT | 35 PT | 35 PT |
| A double-sleeved card | about 55 PT | 35–55 PT | 55 PT |
| A thick-stock or textured card | 75–100 PT | 75–100 PT | 75 or 100 PT |
| A card to be graded, stored long term | about 30 PT | 35 PT | 35 PT (semi-rigid for submission — see the grading guide) |
Two notes on that table. The submission row is deliberately not a recommendation to use a rigid holder: most grading companies specify their own accepted packaging, and a holder that is fine for storage can be the wrong container for a submission. And the sleeve thickness question — why a 50 µm film rather than a stiffer one — is a separate argument about materials rather than sizes, covered in the sleeve article. Both layers, in every size, sit together in Card Protectors.
Frequently asked questions
What does 35 PT mean on a card sleeve?
35 PT means the sleeve or holder is rated for a card up to 35 points thick, where one point is one thousandth of an inch. In metric that is a 0.89 mm opening. It is the standard size for a Pokémon card, and it is generous on a bare card because it is designed to clear the card plus a sleeve.
Is a 100 PT holder bigger than a 35 PT holder?
Thicker, not bigger. The outside footprint of a rigid holder is 3 × 4 inch at every PT, so a 100 PT holder occupies exactly the same space on a shelf as a 35 PT one. The difference is the interior opening: 2.54 mm against 0.89 mm. Only the space inside changes.
What size sleeve fits a Pokémon card?
A standard 63.5 × 88.9 mm sleeve, in the 35 PT option, fits every ordinary Pokémon card regardless of rarity — base, holo, full art, rainbow, secret rare. Rarity changes how a card looks, not how thick the stock is. Sleeve size becomes a real question only for cards with added material, such as relics, or for Japanese-size cards, which are shorter and narrower than standard.
Do expensive cards need a thicker sleeve?
No. A thicker sleeve does not protect a card better, and a thick film pressed against a card face is worse for it than a thin one. Value is a reason to add a rigid layer outside the sleeve, not to increase the PT of the sleeve. A 35 PT sleeve under a 35 PT holder protects a $5 card and a $500 card identically — the difference worth paying for is the second layer, not the number on the first one.
Can I put a sleeved card into a 35 PT holder?
Yes — that is the arrangement 35 PT exists for. A standard card plus a 35 PT sleeve measures roughly 30 PT together, which leaves a small clearance inside a 35 PT opening. If the card is double-sleeved, or the stock is thicker than usual, the combination will outperform 35 PT and you need to move up to 55 PT or higher. If the card meets resistance going in, the size is wrong, not the technique.
