The heavy doors of the Sistine Chapel creak shut. A Swiss Guard stands watch. Inside, the "Princes of the Church" prepare to do something they’ve done for centuries: pick a new leader for over a billion people. But before the first ballot is cast, there’s a numbers game that most people outside the Vatican walls don't quite grasp.
Honestly, the math isn't as simple as checking a roster.
When you ask how many cardinals are there in the conclave, you aren't just asking for a head count. You're asking about the "electors"—the specific group of men under the age of 80 who hold the keys to the future. As of early 2026, the College of Cardinals sits at 245 members total. But here's the catch: only 122 of them are eligible to actually vote.
The rest? They're basically the elders of the group. They offer advice during the "General Congregations" (those pre-conclave meetings where everyone gets to air their grievances), but once the Extra Omnes ("everyone out") command is given, they have to leave the room.
The Rule of 120 (and Why Popes Break It)
Back in 1975, Pope Paul VI looked at the growing Church and decided things were getting a bit crowded. He set a hard cap. No more than 120 cardinal electors at any one time. It was a practical move to keep the election from becoming an unmanageable mob.
But popes are, well, popes. They can change the rules.
St. John Paul II regularly ignored that 120 limit. Pope Francis? He blew right past it. At one point in late 2024, the number of voting cardinals surged to 140. It was a massive expansion designed to "de-Europeanize" the Church. He brought in voices from Tehran, Tokyo, and even the tiny Catholic community in Mongolia.

Why does this matter for the next conclave?
Because more voters mean more unpredictability. When you have a tight group of 110 Italians and Western Europeans, everyone knows each other’s favorite espresso brand. When you have 122 or 135 electors from 70 different countries, the "front-runners" often disappear within the first three ballots.
Age is More Than a Number
The 80-year-old cutoff is brutal. If a cardinal turns 80 the day before the Pope dies, he’s in. If he turns 80 the day after the Pope dies, but before the conclave starts, he’s still in. But if he hits that milestone even an hour before the "Sede Vacante" (the vacancy of the See) officially begins, he loses his vote.
It’s a countdown that every Vatican watcher tracks with obsessive detail. Throughout 2026, seven major cardinals will hit that 80-year mark. This includes figures like Cardinal Michael Czerny, a key ally of the previous administration. Each time a birthday candle is blown out, the balance of power shifts.
Who is Actually Sitting in Those Chairs?
If a conclave were called today, the room would look vastly different than it did in 2013. You’ve got a massive block of Francis-appointed cardinals—roughly 100 of the 122 electors.
- Europe: Still the largest block with about 50+ voters.
- The "Global South": Africa, Asia, and Latin America now hold enough sway to block any candidate they don't like.
- North America: A stable but smaller group, including heavyweights from Chicago, New York, and Toronto.
It’s not just about geography, though. It’s about the "flavor" of the Church. The current crop of cardinals includes a lot of "pastoral" guys—men who have spent more time in slums or refugee camps than in ivory towers. You've got Father Timothy Radcliffe, a British theologian known for being a bit of a maverick, sitting alongside Cardinal Mykola Bychok, who at 44 is the youngest "Prince" in the room.

Imagine that: a 44-year-old and a 79-year-old deciding the fate of an ancient institution. The age gap alone creates a fascinating tension.
The Practical Side of the Numbers
You might wonder why they don't just let everyone vote.
Logistics.
The cardinals live in the Domus Sanctae Marthae, a guesthouse inside the Vatican. It has about 130 suites. If you have 200 voters, you literally run out of beds. Plus, the voting process is manual. Each cardinal walks up to the altar, holds up his folded ballot, and swears an oath before dropping it into a chalice. With 120 people, that takes a while. With 250? You’d be there until the next century.
Also, there's the "Two-Thirds" rule. To become Pope, you need a two-thirds majority.
- If there are 122 electors, a candidate needs 82 votes.
- If the number was higher, say 135, they’d need 90.
Every extra person in the room makes that "magic number" harder to reach. It's how you end up with multiple days of black smoke.

What Most People Get Wrong About the Count
The biggest misconception is that the "College of Cardinals" and the "Conclave" are the same thing. They aren't.
I've seen so many news reports say "245 cardinals will elect the next Pope." No. They won't. About half of them will be watching on TV from their retirement homes. The "Conclave" is a subset of the "College."
Another thing: being an elector is a right, but it’s not guaranteed. A cardinal can be stripped of his "rights and privileges." Look at Angelo Becciu. He’s still a cardinal in name, but because of legal troubles and a Vatican court conviction, he won't be entering the Sistine Chapel. He’s a "non-voting cardinal" even though he’s under 80.
Actionable Insights for Vatican Watchers
If you're trying to keep track of how many cardinals are there in the conclave for an upcoming election, don't just look at the total number. Follow these steps to get the real picture:
- Check the "Under 80" List: Use the official Vatican Press Office bulletins or reliable sites like Catholic Hierarchy.
- Monitor Birthdays: In 2026, the numbers change frequently. A "voting" cardinal in January might be a "retired" cardinal by June.
- Look at the Consistories: If the Pope announces a "Consistory for the creation of new cardinals," expect the voting pool to jump. This is usually done to "top up" the numbers back toward that 120-130 range.
- Identify the "Kingmakers": Groups like the C6 (the Council of Cardinal Advisers) often hold more sway than their single vote suggests.
The conclave isn't just a religious ritual; it's a high-stakes political event with a very strict entry list. Keeping an eye on the count is the only way to guess which way the white smoke will blow.
