The funniest rounds of Cards Against Humanity almost always come from the moments when someone plays a card that references a shared memory, an inside joke, or something that only your specific friend group would find absurd. The game’s official blank cards are a start, but purpose-built blank card sets, write-your-own expansion kits, and compatible custom expansion packs give you far more cards, better card stock, and more flexibility to build rounds that are genuinely tailored to your table. Here are five of the best options for making game night permanently funnier.

Cards Against Humanity Blank Card Set
The official Cards Against Humanity Blank Cards pack is the most direct way to add custom rounds to your existing game. The cards use the same card stock, finish, and exact dimensions as the original game - so your handwritten additions shuffle in seamlessly and feel like real cards rather than obvious inserts. You get a mix of blank black prompt cards and blank white answer cards. Permanent marker writes cleanly on the matte surface.
Pros: Identical card stock and size to original game, official product, black and white card mix included Cons: Limited card count per pack, no printed guidelines for writing prompts - you’re on your own creatively
Blank Slate Game
Blank Slate is a different kind of customizable card game - players fill in a word that completes a prompt, trying to match what others write. What makes it relevant here is that the prompts are intentionally open-ended and the game includes space for players to write and add their own prompts. The whiteboard-style scoring board wipes clean for reuse, and the game plays fast enough for mixed-age groups, making it a useful complement to heavier adult card games.
Pros: Reusable wipe-clean components, extensible with custom prompts, plays well with mixed audiences Cons: Different gameplay format than CAH - better as a complement than a replacement for hardcore CAH fans
What Do You Meme Custom Expansion
What Do You Meme’s core game is already built around player-written captions for photo cards, which makes it inherently customizable. Their expansion packs extend the card pool significantly, and the blank card packs let you insert your own photos (printed and cut to size) or write custom captions. The format works especially well for groups with heavy social media humor since the caption game is the same one everyone plays in the comments section daily.
Pros: Caption format naturally extensible, custom photo compatibility, expansion packs widely available Cons: Requires printing and cutting custom photos to size for full visual customization, humor relies heavily on meme familiarity
Joking Hazard Blank Card Pack
Joking Hazard, from the Cyanide and Happiness creators, is a comic-strip completion game where players build three-panel comics from cards. The official blank card expansion pack gives you white comic-panel cards to draw your own scenes into - making it one of the few party card games where drawing ability (or glorious inability) is part of the joke. Your hand-drawn panels shuffle into the deck and create unique combinations every round.
Pros: Unique draw-your-own format, blank panels shuffle into main deck seamlessly, generates genuinely unique rounds Cons: Requires some willingness to draw - pure non-artists may feel less engaged, needs pens or markers not included
Make Your Own Card Game Kit
For groups who want to build a completely original party card game from scratch rather than expanding an existing one, Make Your Own Card Game kits provide blank card sets, game design prompt sheets, and in some versions, instruction booklets on game structure. These kits work well for office team-building games, bachelorette and bachelor parties, and family reunion events where inside references need to be the entire game rather than an expansion. The card stock quality varies by brand, so read reviews on specific listings.
Pros: Total creative freedom, purpose-built for custom game design, good for themed events Cons: Requires significant writing and creativity investment, quality varies widely by kit brand - read specific reviews
What to Look For
Card stock weight: Thicker card stock (300gsm or heavier) shuffles better, resists bending at corners, and holds up to multiple game nights. Thin card stock feels cheap and dog-ears fast.
Surface finish and writability: Matte surfaces accept permanent marker cleanly. Glossy or laminated cards require oil-based paint markers or paint pens to write on without smearing. Check the product description or reviews for write-on compatibility.
Exact dimensions for CAH compatibility: Standard CAH cards are 3.5 x 2.5 inches. If you want blank cards to shuffle into your existing CAH deck, verify dimensions match before ordering.
Black and white card ratio: Good custom CAH play needs both black (prompt) cards and white (answer) cards. Some blank packs include only white cards - make sure the pack you order covers both if you need them.
Event-specific quantity: For a one-night game, 20 to 30 cards is plenty. For a recurring game group that plays weekly, order 100-card packs so you have room to build and rotate custom content without running out.
Final Thoughts
For the purest CAH experience, the official blank card set is the obvious choice - the stock matches exactly and the results look like they came with the game. Groups who want something more visually creative should look at Joking Hazard’s blank panel pack, where drawing your own content adds a layer of absurdity that’s hard to replicate with text alone. What Do You Meme is the best pick if your group’s humor lives primarily online. For a fully original custom game built around a specific event, a Make Your Own Card Game kit gives you the most flexibility. Whatever you choose, spend time writing good prompts - the card quality matters far less than the content you put on them.
Frequently asked questions
What is the best pen or marker to use on blank game cards?+
Fine-tip permanent markers work best on standard card stock game cards - Sharpie Ultra Fine Point is the most commonly recommended option. For cards with a glossy coating, a paint marker or oil-based paint pen produces a cleaner write. Ballpoint pens work on uncoated matte cards but may smear on laminated stock. Always do a test on a single card before writing your entire set.
How many blank cards should I add to a Cards Against Humanity game?+
The official Cards Against Humanity game recommends adding no more than 30 blank cards total - roughly 20 white answer cards and 10 black prompt cards. Adding too many custom cards dilutes the pacing of the original content and can slow down rounds if players have to read unfamiliar in-jokes repeatedly. A focused set of 15 to 20 high-quality custom cards tends to generate more laughs than 50 mediocre ones.
Can I use blank card sets with other party card games besides Cards Against Humanity?+
Yes. Most blank white-card sets are the same size (3.5 by 2.5 inches) as standard playing cards and work equally well as custom expansions for Joking Hazard, What Do You Meme, and similar party games. Some sets are specifically sized to match CAH exactly - check the dimensions on the product listing if compatibility with a specific game is important to you.
