For Readers in a Hurry
TL;DR: Measure your cards in millimeters. Buy sleeves that are 1–2mm larger than your cards on each side. Slide each card in from the bottom-up while pinching the sleeve open with your thumb. That's it.
That's the secret I wish someone had told me before I destroyed a $60 deck of Mysterium cards with cheap penny sleeves that were 3mm too tall.

Why You Should Trust This Guide
I've been sleeving cards for the better part of seven years, ever since I warped the Codenames key cards by spilling iced coffee on game night (rest in peace, original deck).
Since then, I've sleeved roughly 40 game collections, from the tiny, delicate cards of Sushi Go! to the oversized vision cards of Mysterium. I've made every mistake. I've wasted hundreds of dollars on the wrong sleeves. I've learned which brands genuinely protect your investment — and which ones are glorified plastic wrap.
> "This guide is the brutally honest, dollar-by-dollar, mistake-by-mistake breakdown I wish existed when I started."
We'll cover sizes, materials, the actual sleeving process, and which games in my collection were absolutely worth the cost — and which weren't.
I once watched a friend's $90 copy of Wingspan lose its resale value entirely because of food stains on just 6 cards. Sleeves would have cost him $12. That's a 650% loss over the price of a pizza.
Why Sleeve Board Game Cards At All?
Here's the harsh truth most hobbyists discover too late: most board game cards are printed on linen-finish cardstock that looks beautiful for about 20 plays.
After that? The slow death begins.
Corners start fraying like an old paperback after 20–30 plays.
Skin oils darken the edges into a permanent yellowish halo.
Heavily-handled cards become identifiable from the back.
That last point is a game-killer. In titles like Codenames or Mysterium, marked cards literally break the hidden-information mechanic that makes the game work.

Watch: The Sleeving Process in Action
If you're a visual learner, this walkthrough will save you hours of trial and error and a small fortune in ruined sleeves:
Sleeve in batches of 20 with the TV on. Your back will thank you, and a 200-card deck takes about 25 minutes once you find your rhythm.
Quick Picks: Games Most Worth Sleeving
If I were rebuilding my entire collection from scratch tomorrow, these are the games I'd sleeve first — in this exact order:
| Game | Card Count | Sleeve Size (mm) | Priority |
|---|---|---|---|
| Codenames | 200 | 59 x 92 | CRITICAL |
| Exploding Kittens | 56 | 63.5 x 88 | HIGH |
| 7 Wonders | 184 | 65 x 100 | HIGH |
| Unstable Unicorns | 135 | 63.5 x 88 | HIGH |
The word cards get touched by every player every single round. Without sleeves, you'll have identifiable cards within 15 plays — and the whole game collapses the moment your spymaster realizes they can read the back of the card.

The Bottom Line
Sleeving isn't about being precious with your hobby. It's about respecting a $60 investment that brings your friends together. A $12 pack of premium sleeves is the cheapest insurance policy you'll ever buy.
> My final word: The games you love deserve to last. Measure twice, sleeve once, and never lose another deck to a spilled drink.
