A Pokemon card measures roughly 63mm × 88mm (2.5in × 3.5in) — Japanese and English releases share the same physical card size, the “poker-size” trading-card format used across most of the hobby. What actually changes between the two markets is language and print run, not the piece of cardboard in your hand.
That single fact settles most of the practical questions collectors ask: which sleeves fit, whether a Full Art card needs a bigger toploader, and what happens to the size once a card goes into a PSA slab. This guide works through each of those, plus the clearest exception we could verify — oversized Jumbo promo cards — using the most consistent measurement sources available, since neither an official Pokemon spec page nor a matching PSA holder-size page was found during fact-checking for this piece.
Standard Pokemon cards are commonly reported at 63mm × 88mm (2.5in × 3.5in) — the same size used industry-wide for Magic: The Gathering and other trading card games, and identical between Japanese and English print runs, so the same sleeves and toploaders fit both. A PSA10 Blastoise 003/032, currently listed at ¥18,128 (~$114), is a standard-size single before grading; once slabbed, a PSA holder runs roughly 3¼in × 5⅜in (~83mm × 136mm), regardless of the card’s language. Our Pokemon Card Game Classic, currently listed at ¥84,000 (~$528) (update: currently sold out — restock requests via Quick Order), reprints cards from multiple eras at that same dimension, which is a useful reminder of how stable the spec has stayed. The clearest exception we could verify is genuinely oversized Jumbo promo cards.

The Standard Pokemon Card Size: 63mm × 88mm
The figure quoted most consistently across independent measurement guides is 63mm × 88mm, or 2.5in × 3.5in in imperial terms. That’s the same physical footprint as the “poker size” used across the wider trading card industry (narrower “bridge size” cards, at roughly 57mm wide, are a different format), which is why Pokemon cards fit into the same sleeves, toploaders, binder pages and deck boxes made for Magic: The Gathering and most other TCGs.
| Measurement | Metric | Imperial |
|---|---|---|
| Width | ~63mm | ~2.5in |
| Height | ~88mm | ~3.5in |
Worth flagging for anyone who needs precision — ordering custom-fit display cases, for example — that this pass didn’t turn up an official pokemon-card.com or Bulbapedia page publishing an exact millimeter spec. The 63mm × 88mm figure is a well-corroborated consensus number, not a manufacturer-confirmed one, so treat it as reliable for everyday use rather than as a certified tolerance.
That consistency matters more than it sounds. A card printed in 1996 and a card printed in 2026 both need to fit the same sleeve, the same binder page, and the same toploader — and by every account they do. The spec hasn’t moved across eras, languages, or rarity tiers.
Japanese vs English Pokemon Cards: Same Size, Same Sleeves
Because the physical card stock follows a shared TCG-industry standard rather than a per-market spec, Japanese and English Pokemon cards use the same card size — and by extension, the same body sleeves and toploaders. That’s the consistent explanation across the measurement sources reviewed for this guide, rather than a direct statement from The Pokemon Company, so it’s best treated as widely reported rather than officially confirmed.
In practice, this means a collector who owns both Japanese and English binders doesn’t need two different sets of supplies. A standard penny sleeve or toploader bought anywhere fits a Japanese single the same way it fits an English one.
It also means dimensions can double as a rough authenticity check — a card that’s noticeably off from 63mm × 88mm, or that feels wrong in a standard sleeve, is a signal worth investigating further. Size and thickness are part of what our guide to spotting fake Japanese Pokemon cards covers in more depth. For the broader set of differences between Japanese and English releases — pricing, availability, print runs — rather than the physical spec covered here, see our full Japanese vs English Pokemon cards guide.
Does Full Art Change the Card Size? No — Here’s Why
“Full Art” describes an art style, not a physical format. A Full Art card is one where the illustration runs across the full face of the card — typically the background as well as the Pokemon or Trainer — rather than sitting inside a bordered artwork box. The card itself is still cut to the same standard size as every other card in the set.
That holds across the Japanese rarity system too: SAR, AR, SR, UR and similar full-bleed printings are all Full Art treatments on a standard-size card, not a separate physical product. If you’re holding a Japanese SAR next to a Common from the same set, they should measure the same — only the printing on the surface differs.
This is worth knowing before you buy supplies specifically for “premium” cards. A Full Art single, however elaborate the foiling, still goes into the same sleeve and toploader as a plain Common.
Jumbo and Oversized Promo Cards: The Real Exception
There is one category of Pokemon card that genuinely departs from the standard size: Jumbo cards. These are real, officially produced oversized promos, described as ranging “from slightly larger than a normal sized card to a height of at least eight inches.” They are not tournament-legal and were never meant to be played with — they exist as display and collectible pieces.
Because these are so much larger than 63mm × 88mm, none of the sleeve, toploader or standard PSA-slab guidance in this article applies to them — they need oversized-specific supplies, and grading services handle them under separate holder categories entirely.
PSA Slab Dimensions: How Grading Changes the Size
Once a card is graded, its footprint changes — but not because of anything to do with the card itself. PSA holders (“slabs”) are commonly reported at roughly 3¼in × 5⅜in × ¼in (~83mm × 136mm × 6.5mm). As with the raw card spec above, this is a consistently reported figure across grading-supply sources rather than a page pulled directly from psacard.com in this fact-check, so treat the general size range as reliable and the exact millimeter conversion as a secondary-sourced estimate.
| Spec | Raw card (standard) | PSA slab (encapsulated) |
|---|---|---|
| Width | ~63mm (2.5in) | ~83mm (3¼in) |
| Height | ~88mm (3.5in) | ~136mm (5⅜in) |
| Thickness | Not covered by verified sources for this article | ~6.5mm (¼in) |
The important point for cross-border buyers: the slab size does not change based on the encapsulated card’s language. A Japanese single and an English single of identical rarity go into the same standard PSA holder, because the underlying card they’re built around is the same 63mm × 88mm size either way. The clearest exception we could verify is genuinely oversized Jumbo cards, which need a different PSA holder — covered above.

What This Means When You’re Buying Pokemon Cards from Japan
Because the physical spec is consistent, importing Japanese Pokemon singles doesn’t require any special supplies. Standard sleeves, toploaders, binder pages and PSA holders bought anywhere handle Japanese cards exactly the way they handle English ones — there’s no separate “Japanese size” to plan around.

What does differ in size, obviously, is sealed product — a booster box or a structure-deck box is a much larger item than any single card, and box dimensions aren’t governed by the 63mm × 88mm card spec at all. A few examples currently listed on our site:
- A raw or graded single, like the PSA10 Blastoise 003/032, currently listed at ¥18,128 (~$114), is the standard 63mm × 88mm card size — in this case, already inside a PSA holder.
- The SV2A Pokemon 151 Japanese Pokemon Booster Box, currently listed at ¥43,860 (~$276), is sealed packaging — its outer box is much larger than a card, though the packs and cards inside follow the same standard card dimensions once opened.
- The Starter Set ex Eevee ex, currently listed at ¥2,912 (~$18) (update: currently sold out — restock requests via Quick Order), is a structure-deck box — the same packaging-vs-card distinction applies.
- The Pokemon Card Game Classic, currently listed at ¥84,000 (~$528) (update: currently sold out — restock requests via Quick Order), reprints cards spanning multiple eras, all at the same standard dimensions discussed above.
Both are sealed-packaging examples — the box dimensions themselves are unrelated to the 63mm × 88mm card spec discussed throughout this guide; it’s only the cards and packs inside that follow it.

Frequently Asked Questions
What is the standard size of a Pokemon card in mm?
Pokemon cards are commonly reported at 63mm × 88mm (2.5in × 3.5in), the same “poker size” trading-card format used industry-wide, including for Magic: The Gathering (the narrower “bridge size” used for some other card games is a different format). This figure is consistently corroborated across independent measurement sources, though no official pokemon-card.com or Bulbapedia page with an exact millimeter spec was found during this fact-check.
Are Japanese Pokemon cards a different size than English ones?
No. Japanese and English Pokemon cards share the same 63mm × 88mm card size, which is why the same body sleeves and toploaders fit both. This is a widely reported explanation based on the shared TCG-industry card-stock standard, rather than an official statement from The Pokemon Company.
Are Full Art Pokemon cards bigger than normal cards?
No. “Full Art” refers only to the artwork covering the full face of the card, not a larger physical format. Full Art singles — including Japanese SAR, AR, SR and UR printings — are the same standard size as any other card in the set.
What are Jumbo Pokemon cards?
Jumbo cards are genuine, officially produced oversized promotional cards, ranging from slightly larger than a normal card up to at least eight inches tall. They are not tournament-legal and are typically distributed at events — in Japan, things like Pokemon Center reopenings or JR Train Stamp Rallies — rather than sold as ordinary singles.
What size is a PSA graded card slab?
PSA holders are commonly reported at roughly 3¼in × 5⅜in × ¼in (about 83mm × 136mm × 6.5mm). That slab size doesn’t change based on whether the encapsulated card is Japanese or English — the clearest exception we could verify is genuinely oversized Jumbo cards, which need a different PSA holder.
Do I need different sleeves for Japanese Pokemon cards?
No. Because Japanese and English Pokemon cards share the same standard card size, the same body sleeves, toploaders and binder pages work for both — there’s no separate “Japanese size” to buy supplies around.
