Protect What You Chased
You picked the card, pulled the odds, and it hit. Now don't ruin it with the wrong size holder. Here's what "PT" means, which size fits which card, and why the sleeve goes on first.

What "PT" Means
PT stands for "point," and one point equals one thousandth of an inch (0.001"). It's the same unit printers use for paper and card stock thickness, which is why it carries over to the plastic that protects the card.
The number on a toploader (35pt, 100pt, 180pt...) is the interior capacity it's built to hold, not a spec of your specific card. A standard raw sports or TCG card runs about 20pt on its own. A 35pt toploader gives that card room for a penny sleeve plus a little slack, which is why it's the default size almost everyone reaches for first.
Penny Sleeves: The First Layer
A penny sleeve is a thin, soft plastic sleeve the card goes into before anything rigid. The name is a leftover from when they cost about a penny each, and functionally nothing has changed: it's the cheapest, most basic layer of protection there is.
What it does: stops surface scratches, fingerprint oils, and dust from touching the card face. What it doesn't do: stop the card from bending, creasing, or taking a corner ding. A sleeve alone is not enough for anything you'd care about damaging, it needs a rigid holder over the top.
When buying sleeves, look for the words "acid-free," "PVC-free," and "polypropylene" on the packaging. Those three together are the archival-safe combination. A sleeve that just says "crystal clear" with none of that language may be plain vinyl, which isn't something you want in long-term contact with a card.
Always Sleeve, Then Toploader
Most rigid toploaders are made of PVC. Modern PVC toploaders are far more stable than the soft vinyl used decades ago, but PVC can still give off trace acidic vapor over years of direct contact with cardboard. The standard fix, and the near-universal advice across the hobby, is simple: a raw card never touches the toploader directly.
Slide the card into a penny sleeve first, then slide the sleeved card into the toploader. This does two things: it puts an acid-free barrier between the card and the PVC, and it stops the card from rattling around loose inside the toploader, which is its own slow source of edge and corner wear.
Toploader Size Chart
Card stock thickness varies by manufacturer and product line, so treat this as a starting point, not a guarantee. When a card sits right between two sizes, size up: a slightly loose toploader is harmless, a tight one isn't.
| PT | Fits |
|---|---|
| 35pt | The default. Standard raw base cards and most parallels, sleeved, with normal card stock. Covers the large majority of modern cardboard. |
| 55pt | Slightly thicker stock (some Chrome, Prizm, and Optic base runs a hair heavier than plain cardboard) or two thin cards sleeved back to back. |
| 75pt | Thin jersey or relic cards, standard-stock single swatch memorabilia. |
| 100pt | The other size most collectors own. Standard single-patch, autograph, and relic "hit" cards. |
| 130pt | Multi-color or multi-piece patches, thicker relic cards, most numbered "cup" cards. |
| 180pt | Jumbo or logo patches, helmet and stick swatch cards. |
| 200pt+ | Laundry-tag patches and oversized manufactured relics. At this thickness, check the "When a Toploader Isn't the Right Tool" section below before buying one. |
One-Touch Magnetic Holders
A one-touch is a rigid holder built from two magnetic halves that clamp shut on all four sides, instead of the single open slot on a toploader. The card still goes in sleeved first, same rule as above, but once it's closed there's no gap left for it to shift or rattle around inside.
That sealed fit is the whole point. A toploader is open at the top, so the card can slide, and repeated in-and-out handling is itself a slow source of edge wear. A one-touch holds the card fixed in place and looks better held up to a camera or passed around at a show, which is why collectors reach for one on a card they plan to display or handle a lot rather than just file away.
Sizing works off the same PT numbers as toploaders (see the chart above), and the same rule applies: size up if it feels snug, never force a card into a tight fit.
When a Toploader Isn't the Right Tool
Booklet cards. A hinged, multi-panel book card doesn't sit flat, and folding it to force it into a standard toploader is a fast way to crease it at the hinge. These need a dedicated magnetic booklet holder built for the fold, not a toploader.
Extremely thick specialty relics. Once you're past roughly 200pt, a toploader's open top and single rigid layer start to strain. A one-touch holder seals the card on all four sides instead of one open edge and holds a very thick piece far more securely.
