Whether you're chasing every member's pulls from Proof, hunting down Japanese single cards, or finally giving your lucky-draw cards the home they deserve, one question comes up before anything else: what actually fits a BTS photocard? Get the sizing right and your cards sit snug, display clean, and stay protected for years. Get it wrong and you're left with rattling sleeves, bent corners, or an ugly gap around your bias. This guide covers the exact sizes, the sleeves that fit, and the best binder setup for a BTS collection.

What size are BTS photocards?
The overwhelming majority of BTS photocards — the ones pulled from Korean albums like Proof, BE, Map of the Soul: 7, and Love Yourself — measure about 55 × 85 mm (roughly 2.16 × 3.35 inches), the same footprint as a credit card. If you're sorting through a standard album pull, this is almost always the size in your hand.
The catch is that BTS releases a lot of cards across a lot of formats, and not all of them are standard. Japanese singles, special editions, lucky-draw cards, and fan-event merch can run slightly larger or come in their own shapes — which is exactly why sleeve sizing trips collectors up.
BTS photocard size chart (and the sleeve that fits)
| BTS card type | Where it comes from | Approx. card size | Recommended sleeve |
|---|---|---|---|
| Standard album card | Proof, BE, MOTS:7, Love Yourself | 55 × 85 mm | 57 × 88 mm (snug) or 61 × 91 mm (binder) |
| Japanese / oversized | JP singles, special editions | 56–59 × 86–89 mm | 61 × 91 mm (relaxed) |
| Lucky-draw / fan-event | POB, fansign, pop-up cards | Varies — measure first | 57 × 88 mm or 61 × 91 mm |
| Postcard / large print | Photobook inserts, posters | up to ~102 × 152 mm | 103 × 153 mm postcard sleeves |
Rule of thumb: aim for 1–2 mm of margin on each side — snug enough that the card can't slide, loose enough that it slips in without bending a corner.
The two sleeve sizes that cover almost all BTS cards
For a BTS collection, two sizes do about 90% of the work:
- 57 × 88 mm — the "snug" fit. Hugs a standard 55 × 85 mm album card with minimal edge. It's the cleanest look for display and the most popular single-sleeve choice. (Shop 57×88 clear sleeves →)
- 61 × 91 mm — the "relaxed" / binder fit. A little more room. It's the size that fits most binder pages, and the go-to outer sleeve for double-sleeving rarer pulls. (Shop 61×91 clear sleeves →)
If you remember nothing else: 57×88 to hug, 61×91 to bind or double-sleeve.

The best binder for a BTS collection
BTS has one of the deepest discographies in K-pop, so how you organize matters as much as how you protect. Pair your cards with binder pages sized for 61 × 91 mm sleeves, then pick the binder format that matches your collection size:
| Binder | Best for | Why |
|---|---|---|
| A5 4-pocket | One comeback or one member per book | Compact, travel-friendly, easy to theme |
| A4 9-pocket | The whole discography in one place | More cards per page, great for a complete BTS run |
A5 is the cozy, curated choice; A4 is the "house the entire era" choice. Many BTS collectors run both — an A4 master binder plus A5 minis for favorite comebacks. Browse the full range of photocard binders to find your size.

Displaying your bias
Not every card belongs in a binder — some deserve the spotlight. For cards you want on a shelf or desk, reach for holographic sleeves to add shimmer, or colored sleeves to frame your bias in BTS purple. Both come in 57×88 and 58×89 so your display cards stay just as snug as the ones in your binder.
Protecting rare pulls and trades
For grail cards, lucky-draws, or anything you're shipping or trading, double-sleeve first, then add a toploader:
- Inner sleeve: 57 × 88 mm — snug around the card
- Outer sleeve: 61 × 91 mm — fits over the inner sleeve
- Toploader — rigid protection for transport
This combo gives a no-rattle stack and the safest possible trip through the mail.

Why sleeve quality matters for a long-term collection
A BTS collection is one you keep. Cheap PVC sleeves can cloud, yellow, and leach over time — slowly damaging the cards underneath. Every sleeve we make is PVC-free and acid-free, so your cards stay crystal clear for years. Thickness is a personal call: 100 microns is the flexible everyday standard (perfect for binders), 120 microns adds a bit of sturdiness for frequently handled cards, and 160 microns gives premium rigidity for your most valued pulls.
