What size case does your TRADING card actually need?
35pt to 180pt, explained properly — which one-touch or MagSafe case fits which card, and why forcing the wrong one is how corners die.
Every collector has done it once. You pull a jersey card, grab the case you've got on hand, and push. Something clicks that shouldn't. The card's fine — probably — but you've just learned the hobby's least fun lesson: cases come in sizes, and the sizes matter.
This guide covers every case thickness we stock, what actually fits in each one, and a couple of tricks for working out your card's size without a set of calipers. Ten minutes now saves a dinged corner later.
First: what does "pt" even mean?
Case and toploader thickness is measured in points. One point is one-thousandth of an inch — so a 35pt case has an opening 0.035" (about 0.9 mm) deep. A standard trading card is roughly 20pt thick, which is why 35pt is the everyday size: enough room for the card plus a sleeve, snug enough that it doesn't rattle.
From there, the sizes step up to handle thicker stock, embedded memorabilia, and the properly chunky stuff. Here's the full ladder:
The stack-of-commons trick
No calipers? No problem. Because a regular card is about 20pt, you can gauge any card's thickness by comparing it to a small stack of commons. Hold your card side-on against the stack — whichever it matches, that's your size.
The full breakdown, size by size
Here's what goes where — with real products, not vague categories. These are the same examples printed on our case inserts in-store.
- Pokémon, One Piece, MTG, Yu-Gi-Oh! & Lorcana singles
- Topps & Bowman flagship, Panini Score — anything on standard paper stock
- NBA Hoops, Donruss base
- AFL Select Footy Stars & Brilliance base and standard inserts
- Standard on-card autographs (always sleeved — ink can transfer to acrylic over time)
- Topps Chrome, Panini Prizm, Donruss Optic — anything on chromium stock
- Topps & Bowman Chrome UEFA and soccer
- Select AFL Future Hall of Fame & ShowStoppers
- MLB Bowman Chrome autos
- Sticker autographs on chrome stock
- Case-hit inserts — Downtowns, Kabooms
- Panini Contenders Optic
- Upper Deck SPx hockey
- Bowman Invicta — noticeably thicker than its own base set
- Select AFL Certified Jersey Patch & Jersey Patch Auto
- Thin single-swatch jersey cards, like Topps flagship relics
- NBA & NFL jersey cards — Donruss, Optic, Prizm, Limited
- Topps commemorative logo patch cards
- Topps Triple Threads & Tribute relics
- Absolute Football jersey cards
- Topps Eccellenza base and numbered cards

- Topps Eccellenza relic cards
- Jumbo and logo patch cards — Immaculate jumbos, NT Colossal
- Multi-relic and tool-of-the-trade cards
- Booklet cards, folded closed (open display needs a booklet holder — ask us)
Topps Eccellenza is the perfect example of why this guide exists. The base and numbered cards need a 100pt case — already thick. The relics from the very same set need a 180pt. One product, two sizes, nearly double the thickness.
Sizing isn't uniform within a set, let alone across the hobby. Which is why the only universal rule is the one below.
The one rule that never fails
The most common mistake we see — by a distance — is a jersey card being pushed into a 35pt because that's what was in the drawer. If a sleeved card doesn't slide or sit in with gentle resistance, stop. Don't push harder. Go up a size.
The reverse mistake is rarer but real: a standard single rattling around a 100pt case will pick up edge wear from the movement. The goal is snug, not tight — the card sits flat, doesn't press against the acrylic, doesn't slide when you tilt it.
Three habits that protect every card
Always sleeve first. A penny sleeve between card and case prevents surface scratches and stops autograph ink transferring to acrylic. Standard sleeves work up to about 75pt; from 100pt up, switch to thick sleeves.
Check before you buy the case, not after. Use the stack-of-commons trick, or bring the card in — we keep a thickness gauge at the counter and we'll size it on the spot. No charge, no dumb questions.
Borderline card? Size up. Some brands make a 160pt, some don't; some patches run thicker than their product's norm. If your card sits between sizes, the bigger case wins every time.
