Wondering if Star Realms and Hero Realms sleeves are interchangeable? We compare sizes, compatibility, and what to consider before buying.
Quick Answer
Star Realms and Hero Realms are different games, so their sleeves are not necessarily the same. However, both use standard card sizes, so many sleeves are compatible. Check the specific sleeve dimensions and card counts for each game before buying.
If you play both Star Realms and Hero Realms, you might wonder if you can share sleeves between the two games. After all, both are deck-building games with similar card sizes. But are the sleeves truly interchangeable? The short answer is: it depends on the sleeve size and the card dimensions.
In this comparison, we'll break down the differences and similarities between Star Realms and Hero Realms sleeves, so you can decide whether to buy separate sleeves or use a universal option. We'll also look at what to consider when sleeving your cards to keep them in top condition.
Card Sizes: The Key to Compatibility
The most important factor in sleeve compatibility is card size. Star Realms cards are standard poker-size (63x88mm), while Hero Realms cards are also standard size. This means that many sleeves designed for one game will fit the other. However, there can be variations in card thickness and finish, so it's always a good idea to test a single sleeve before committing to a full set.
If you're using sleeves with a matte finish, they may feel different between the two games. Matte sleeves reduce glare and are less slippery, which can be beneficial during long play sessions. But if you're mixing sleeves from different brands, the shuffle feel might not be consistent.
- Always check the sleeve dimensions (width x height) to ensure a snug fit.
- Consider the thickness of the cards – some games have thicker cards that may not fit in standard sleeves.
Sleeve Counts and Expansions
Another consideration is the number of sleeves you need. Star Realms has a large number of expansions and promo cards, so you might need more sleeves than you think. Hero Realms also has many expansions, including character packs and campaign decks. If you plan to sleeve your entire collection, you'll need to account for future expansions.
The Sorcerer Sleeves (50) are an example of a specific sleeve product. They are 67mm x 92mm, which is slightly larger than standard poker-size sleeves. This might be due to the card size in Sorcerer, a different game. For Star Realms and Hero Realms, you'll typically use standard 63x88mm sleeves.

- When buying sleeves, consider buying extra to accommodate future expansions.
- Keep a spreadsheet of your card counts to avoid running out of sleeves mid-game.
Tradeoffs to Consider
- Sleeve Size: Standard poker-size sleeves (63x88mm) fit both Star Realms and Hero Realms. However, some sleeves like Sorcerer Sleeves are larger (67x92mm) and won't fit. Always verify sleeve dimensions before purchasing.
- Sleeve Count: Star Realms and Hero Realms have different card counts, especially with expansions. Buying a single pack may not be enough for your entire collection. Calculate your total card count and buy accordingly.
- Sleeve Quality: Matte finish sleeves reduce glare but may feel different between games if you mix brands. Consistency in shuffle feel can matter for competitive play. Stick to one brand for a consistent feel.
Product Facts and Why They Matter
- Sorcerer Sleeves (50): 67mm x 92mm, 50 count pack, matte finish, PVC and acid-free. These sleeves are designed for Sorcerer grimoire cards, not Star Realms or Hero Realms. Their size is different, so they won't fit standard cards. Always check the dimensions before buying.
- Star Realms Universal Storage Box: Holds your entire Star Realms collection, with or without sleeves, with room to spare for future sets and even a playmat. Includes foam blocks and plastic dividers. If you sleeve your cards, the extra thickness takes up more space. This storage box is designed to accommodate sleeved cards, so you can keep your collection organized without worrying about fit.
How to Choose the Right Sleeves
Best for
- Players who want to sleeve both Star Realms and Hero Realms with the same standard-size sleeves.
- Collectors who need a storage solution that fits sleeved cards, like the Star Realms Universal Storage Box.
Not for
- Players using games with non-standard card sizes (e.g., Sorcerer), as those require specific sleeves.
- Those who prefer penny sleeves (thin, cheap) for casual play, as they may not offer enough protection.
In summary, Star Realms and Hero Realms sleeves are not the same product, but they are often compatible due to similar card sizes. Before buying, check the sleeve dimensions, consider the number of cards you need to cover, and think about future expansions. With the right sleeves, you can protect your cards and enjoy your games for years to come.
