One card per player plus 10–15% spares covers most games, two cards each if the group is adults who want a longer game. The full chart below breaks that down for 8 to 100 players, however big your room is. Go ahead and print as many unique bingo cards as you need, free, in under a minute.

“Sheets of paper at 2-up” is the one-each column plus its spares, at 2 cards per sheet, rounded up to a whole sheet. Printing two-up instead of one-per-page roughly halves your paper for the same number of cards, at a card size still comfortable for anyone to read.

Why you print spares
Three reasons, every time: a latecomer who wasn’t on the original headcount, a misprint or a jam partway through the run, and a child (or, occasionally, an adult) who loses or damages a card mid-game and needs a replacement without holding up the room. The 10–15% rule above covers all three without meaningfully adding to your print job, a 30-player game printing 2 spares is a trivial cost next to the alternative of stopping the game to reprint one card by hand. Keep the spares in a separate small stack near the host rather than mixed into the main pile, handing one to a latecomer takes a few seconds if it’s already set aside, and a lot longer if you’re hunting through a stack of cards that’s already been distributed.
One card each or two?
One card each suits young children and seniors who are still learning to track a pattern, tracking two cards at once adds real cognitive load before someone’s comfortable with just one. Two cards each suits an adult party that wants a longer, livelier game, everyone’s watching two boards, which keeps attention up between calls. Three or more cards is really only for regular players who specifically enjoy the challenge of tracking several at once, most casual games don’t need it.
One thing to plan around: more cards in play per person means somebody completes the pattern sooner, on average, simply because there are more cards racing for the same win. If your group is playing two cards each, pick a slightly harder pattern (a full line instead of four corners, or blackout instead of a line) to keep the round from ending almost as soon as it starts. The same logic runs in reverse too, a small group of eight playing two cards each is effectively playing a sixteen-card game, closer in pace to a much bigger single-card room than the headcount alone suggests, so don’t be surprised if a quick pattern finishes faster than the chart’s typical times imply for that group size.
Do the cards have to be different?
Yes, if there’s a prize on the line. Two identical cards in the same game both complete the pattern on the exact same call, producing a tie neither player expected and no clean way to award a single prize. A generator sidesteps this automatically, every card it produces is unique, so you never need to check by hand. The number of distinct 5x5 cards a generator can produce is large enough that two identical cards appearing by chance isn’t something worth worrying about, even for the biggest group this chart covers.
15 things to use as bingo markers when you don’t have daubers
Choking-hazard note: small or edible markers (beans, cereal, candy, Lego bricks, buttons) are not appropriate for children under three who might put them in their mouth. Use a pencil X or paper squares instead for a toddler-age group.
- Dried beans — cheap, plentiful, works for any group. A standard bag covers roughly 40 cards.
- Uncooked macaroni — same idea as beans, a little easier to pinch for small hands.
- Pennies — always on hand, and heavy enough not to slide off a card easily.
- M&Ms or Skittles — a treat that doubles as a marker, popular with kids (choking hazard for under-threes, see above).
- Mini marshmallows — soft, easy to place, same age caution as candy.
- Cheerios — an edible marker that’s also a snack while you play, same age caution applies.
- Goldfish crackers — same idea, popular at kids’ parties.
- Buttons — reusable, and big buttons are easy to see and grip.
- 1x1 Lego bricks — reusable and satisfying to place, choking hazard for under-threes.
- Pom-poms — soft, colorful, and easy for smaller or less steady hands to pick up.
- Torn squares of scrap paper — free, and works well in a classroom with no shopping required.
- Plastic bottle caps — reusable, and a good size for younger children to handle.
- Sticky flags (page-marker tabs) — peel and stick, no loose pieces to spill or lose.
- Sticker dots — same idea as sticky flags, and doubles as a permanent record of a finished card.
- A pencil X on a card you reprint each round — the simplest option of all, no markers to buy, lose or clean up, just print a fresh card for the next game.
Best for classrooms: a pencil X or torn paper squares, nothing to lose, spill or choke on. Best for seniors: large flat buttons, bottle caps or pom-poms, easy to see and to pick up with less dexterity. Avoid anything edible or small enough to swallow around toddlers, use the pencil-X or paper-square option instead.
How many markers per card
A 5x5 card needs at least 20 markers per player for a full blackout (25 squares minus the free center), fewer for a quicker pattern like four corners (4) or any line (5). A standard bag of dried beans covers roughly 40 cards at blackout, more if you’re only playing quicker patterns that round. Count out markers by pattern rather than always assuming blackout, if the whole night is quick four-corners and single-line rounds, a handful per player goes a lot further than the blackout figure above suggests, and you’ll spend less time portioning out a marker bowl before the game starts.
What else to print
Beyond the cards themselves: a call sheet to track what’s been drawn and verify claims, a bingo winning patterns chart if your group is playing more than one pattern tonight, and prize slips or tickets if you’re running more than one round with a prize each time.
A printing checklist for a 30-person game
- Cards — 30 plus 2 spares, from the chart above.
- Spares — already included in that count, ready to hand to a latecomer.
- Call sheet — one, to track calls and verify claims.
- Markers — enough for a full blackout per card, 20 each at minimum, from the list above.
- Prizes — one per pattern you’re playing that round.

FAQ
How many bingo cards do I need for 30 players?
30 cards plus 2 spares if everyone gets one each, 62 cards if everyone gets two, see the full chart above for every group size from 8 to 100.
Should everyone have the same number of cards?
Not necessarily. One card each suits young children and seniors who are still learning the pattern, two each suits an adult party that wants a longer, livelier game, and three or more is really only for regular players who enjoy tracking multiple cards at once.
What can you use instead of bingo daubers?
Dried beans, pennies, buttons, mini marshmallows, Cheerios, 1x1 Lego bricks and a dozen other household items all work, see the full list above with notes on which suit classrooms, seniors and toddlers.
How many bingo cards fit on one page?
It depends on the layout, 2 cards per page prints large enough for anyone, 4 per page is the classroom standard, and 6 fits more per sheet at the cost of smaller squares.
Do bingo cards have to be unique?
Yes, if there’s a prize. Two identical cards in the same game produce an unwelcome tie the moment either one completes the pattern. A generator makes every card unique automatically, so this isn’t something you need to check by hand.
