When the black smoke or white smoke starts curling out of that skinny chimney over the Sistine Chapel, the world stops. It’s high drama. But before the doors are locked "cum clave" (with a key), there is always a frantic numbers game going on behind the scenes. People love to quote the "120 rule." They’ll tell you that the College of Cardinals has a hard cap.
They’re wrong. Sorta.
Actually, as of early 2026, the reality on the ground in Rome is much more crowded than the rulebooks suggest. If a conclave were called today, you wouldn't see 120 men walking in. You’d see more. Way more. We just came off a massive shift in 2025 following the election of Pope Leo XIV, and the dust is still settling on the roster of who actually gets a ballot and who has to watch from the sidelines.
The Magic Number 120 (And Why It’s Usually Ignored)
Back in 1975, Pope Paul VI looked at the growing College of Cardinals and decided things were getting a bit out of hand. He penned the Apostolic Constitution Romano Pontifici Eligendo and set a strict limit: 120 cardinal electors. These are the guys under the age of 80 who actually get to vote.
But here’s the kicker. Popes treat that 120 limit more like a suggestion than a law of physics.
John Paul II blew past it. Benedict XVI blew past it. And Pope Francis? He didn't just nudge the line; he sprinted past it. In late 2024, the number of electors hit a staggering 141. By the time the 2025 conclave actually happened in May, the official count of eligible voters stood at 135.
Why does this happen? It’s simple math vs. mortality. A Pope wants to ensure the Church is represented globally, so he appoints a big batch of new cardinals (a consistory). He knows some of the current ones are about to turn 80 and lose their voting rights. So, he "overfills" the room, knowing it’ll drain out naturally over the next few months.
Who Actually Gets Through the Door?
You’ve probably heard that every cardinal is equal. In terms of honor? Sure. In terms of power? Not even close. The Church draws a very sharp line at the 80th birthday.

If a cardinal turns 80 the day before the Papacy becomes vacant (either by death or resignation), he’s out. He can’t vote. He can’t even enter the Sistine Chapel for the balloting. He can attend the "General Congregations"—those pre-conclave meetings where they gossip and talk about the state of the Church—but once the extra security guards show up and the "Extra Omnes" (everyone out) command is given, he’s headed back to his apartment.
As of January 2026, there are 245 cardinals in total. But only 122 of them are currently eligible to vote.
Wait. Didn’t I just say there were 135 recently?
Time moves fast in the Vatican. Since the election of Leo XIV in May 2025, several heavy hitters have hit that 80-year milestone. Mario Zenari, the longtime nuncio to Syria, just turned 80 on January 5th. Christophe Pierre, the man who has been the Vatican's eyes and ears in the United States, hits 80 on January 30th.
The room is shrinking again.
The "Francis Effect" and the 2025 Conclave
The 2025 conclave was a massive turning point. It was the first time in history that a conclave actually took place with more than 120 electors. The College had to issue a special declaration basically saying, "Yeah, the law says 120, but since the Pope appointed 133 of us to vote, we're all going in."
They didn't want a legal crisis on their hands. Imagine electing a Pope and then having some canon lawyer argue the election was void because the room was too full.

What's really fascinating is how the geography has shifted. For centuries, the conclave was basically an Italian country club with a few French and Spanish guests. Not anymore.
- Europe now holds less than 40% of the voting power.
- The Global South (Africa, Asia, and Latin America) is the new powerhouse.
- Religious Orders (Jesuits, Salesians, Franciscans) make up nearly half the voting block.
When Cardinal Robert Francis Prevost was elected as Pope Leo XIV, it was a signal that the "peripheries" Francis talked about were now the center. Prevost, though born in Chicago, spent decades in Peru. He represents that weird, modern blend of the developed and developing worlds.
Common Misconceptions About Conclave Numbers
I hear people get confused about this all the time. Let’s clear up some of the "well, actually" stuff.
1. Can a cardinal over 80 be elected Pope?
Yes. Absolutely. They can’t vote, but they can be voted for. It would be weird, and it hasn't happened in the modern era, but it’s legally possible. Any baptized Catholic male can technically be elected. You don't even have to be a cardinal, though that hasn't happened since 1378.
2. Is 120 the "minimum" needed?
No. If a plague or a plane crash took out half the College, the survivors would still hold the conclave. There is no "quorum" in the way we think of a corporate board.
3. Does the number stay the same during the voting?
Sometimes it drops. In 2025, two electors couldn't make it due to health. Once the doors are locked, if a cardinal gets sick, he has to leave. If he leaves, he can't come back in. The number of votes needed for a two-thirds majority actually shifts if someone has to exit the building.
What to Watch for in 2026
We are currently in a "cooling off" period. Pope Leo XIV is new. He hasn't called his first consistory yet. But keep an eye on the calendar.

Seven more cardinals are hitting the 80-year-old "retirement" mark this year. This includes guys like Michael Czerny, the Jesuit who has been the face of the Church's work on climate change and migrants. When these men "age out," the number of electors will drop toward that 120 mark again.
Kinda makes you realize how much the Pope's pen matters. Every time he names a cardinal, he isn't just giving out a red hat; he's literally rigging the scale for the next election.
Actionable Insights: How to Track the Numbers
If you’re a Vatican watcher or just someone who likes to win trivia night, don't just look at the total number of cardinals. That number is vanity. The only number that matters is the Electors.
- Check the Birthdays: Use a site like Catholic-Hierarchy or the official Vatican Press Office list. Look for any cardinal who is 79. Their "expiration date" for voting is their next birthday.
- Watch the 120 Ceiling: If the number of electors drops to 115 or 110, expect a Consistory. Popes hate letting the number get too low because it reduces the diversity of the vote.
- The Two-Thirds Math: In a conclave, you need two-thirds of the votes. If there are 122 electors, you need 82 votes to become Pope. If there are 140, you need 94. A larger group actually makes it harder to reach a consensus quickly.
The College of Cardinals is a living, breathing, and aging body. It changes every single month. While 120 is the number written in the books, the number that actually matters is whoever is standing in that room when the doors click shut.
Right now? That's 122 men. But by next Christmas? It’ll be a whole different story.
Monitor the upcoming birthdays of Cardinal Juan José Omella and Cardinal Francesco Montenegro later this year to see the voting pool shrink further before the next inevitable expansion.
