Star Realms Sleeves vs. Hero Realms Sleeves: A Detailed Comparison

Quick Answer

Star Realms and Hero Realms sleeves are not interchangeable because the cards are different sizes. Star Realms cards are standard 63.5mm x 88mm, while Hero Realms cards are larger at 67mm x 92mm. For Hero Realms, you need the Hero Realms Sleeves (60) pack; for Star Realms, look for standard-sized sleeves that fit 63.5mm x 88mm cards.

If you play both Star Realms and Hero Realms, you might wonder whether you can share sleeves between the two games. After all, both are deck-building card games with similar themes and mechanics. But the physical cards are not the same size, and that difference matters more than you might think.

In this comparison, we’ll break down the exact dimensions, what they mean for shuffling and storage, and which sleeve option makes sense for each game. You’ll also see why the Hero Realms Sleeves (60) are a specific fit for Hero Realms, and what to look for when sleeving your Star Realms decks.

Card Size Differences: Why It Matters

The most important fact in this comparison is that Hero Realms cards are larger than Star Realms cards. According to the product details, Hero Realms sleeves measure 67mm x 92mm, which is a non-standard size. In contrast, Star Realms uses standard poker-sized cards (63.5mm x 88mm), which are widely available from many manufacturers.

This size difference means you cannot use the same sleeves for both games. If you buy standard sleeves for Star Realms, they will be too small for Hero Realms cards. Conversely, the larger Hero Realms sleeves will be loose and sloppy on Star Realms cards, offering poor protection and awkward shuffling.

• Measure your cards before buying sleeves. If you’re unsure, check the product listing or the game’s rulebook.
• Standard sleeves are easy to find, but Hero Realms requires a specialty size.

Sleeve Count and Coverage: How Many Do You Need?

When you buy sleeves, you need enough to protect your entire deck plus spares for damaged sleeves. The Hero Realms Sleeves (60) pack contains 60 sleeves, which is enough for a typical Hero Realms deck of around 53 cards (including a start deck and market cards). However, if you play with expansions or have extra cards, you may need multiple packs.

For Star Realms, you’ll need to consider the number of cards in your collection. The core set has 128 cards, so you’ll need at least two packs of 60 standard sleeves. Because standard sleeves are widely available, you can buy larger bulk packs to save money.

• Always buy a few extra sleeves to replace worn ones.
• Check the sleeve counts spreadsheet mentioned in the Hero Realms product listing to calculate exact needs.

Material and Finish: What to Expect

The Hero Realms Sleeves (60) are made of PVC and are acid-free, with a matte finish on both front and back. This finish reduces glare and makes cards easier to read under bright lights. The matte back also provides a better shuffle feel than glossy sleeves.

For Star Realms, you have many options: matte, glossy, or textured. Since Star Realms uses standard sizes, you can choose from premium brands like Dragon Shield or Ultra Pro. The choice between matte and glossy often comes down to personal preference: matte reduces glare and is easier to shuffle, while glossy can feel more slippery and may show fingerprints.

• Matte sleeves are generally better for long gaming sessions because they don’t stick together.
• If you play in a well-lit room, matte sleeves reduce eye strain.

Compatibility with Expansions

Both games have expansions that add more cards. For Hero Realms, expansions like the Dragon Boss Deck or character packs use the same larger card size, so the Hero Realms Sleeves (60) remain compatible. You’ll just need more sleeves as your collection grows.

For Star Realms, all expansions—such as Crisis: Fleets & Fortresses or Cosmic Gambit—use standard-sized cards. This means you can sleeve your entire Star Realms collection with the same standard sleeves, regardless of which expansion you own. That consistency is a big advantage if you like to mix and match cards.

• When buying sleeves for expansions, add up the total number of cards you own to determine how many packs to buy.
• Keep spare sleeves in a labeled box so you can quickly replace damaged ones.

Trade-offs to Consider

• Hero Realms Sleeves (60): Specialty fit: These sleeves are a perfect fit for Hero Realms cards, but they are only available in a 60-count pack. If you have a large Hero Realms collection, you may need to buy multiple packs, which can be more expensive per sleeve. Ideal if you only play Hero Realms and want a perfect fit.
• Standard Sleeves for Star Realms: Versatile and affordable: Since Star Realms uses standard card sizes, you can buy sleeves in bulk from any brand, often at a lower cost per sleeve. This is a cost-effective choice, but you need to ensure the quality meets your expectations. Best if you play multiple standard card games or want to save money.
• Mixing Sleeves Between Games: Not recommended: Because the sizes differ, using the wrong sleeves can lead to poor shuffling, inadequate protection, and even damage to your cards. It’s better to keep separate sleeve stocks for each game. Avoid mixing to protect your investment.
