Little League Age Chart: Divisions by Age

In Little League Baseball, the division your child plays in is decided by their “league age,” not simply by their birthday during the season. As of the 2026 season, league age is a player’s age on August 31 of the current year, and that one number places them in the correct division.

Understanding league age is the single most useful thing a Little League parent can learn, because it removes the guesswork from registration. Here is how the cutoff works, the current division chart, and why the rule is built the way it is.

Freshness note: this reflects the age-determination rule for the 2026 season. Little League International sets the cutoff date and has adjusted it before, so always confirm the current date and use the official age calculator on littleleague.org before you register.

How “league age” works

The key idea is that Little League uses a fixed cutoff date, not your child’s actual age on the day they play. As of 2026, that date is August 31.

Whatever age your child is on August 31 of the current year is their league age for the entire season. A child who turns 12 on August 30 has a league age of 12; a child who turns 12 on September 1 still has a league age of 11 for that season. Little League publishes an official age calculator where you enter a birthdate and it returns the league age, which removes any doubt.

That is why two children born only a couple of days apart can end up in different divisions: one falls before the cutoff and one after.

The division age chart

League age maps to divisions in roughly the following bands. Exact eligibility can overlap at the edges, and local leagues have some flexibility, so treat this as the standard guide rather than a rigid rule.

Division	Typical league age
Tee Ball	4 to 7
Minor League	5 to 11
Major Division	9 to 12
Intermediate (50/70)	11 to 13
Junior League	12 to 14
Senior League	13 to 16

The bands overlap on purpose. A league-age 11-year-old, for example, could fit the Major division, the Intermediate 50/70 division, or stay in the Minors depending on their readiness and the local league’s structure. Parents and coaches place a child within the eligible range based on skill and development, not age alone.

A worked example

Say your child was born on September 15, 2014. To find their league age for the 2026 season, you check how old they are on August 31, 2026. On that date they are still 11 (they do not turn 12 until September 15), so their league age is 11, even though they will be 12 for most of the season that follows.

Compare that with a teammate born on August 1, 2014. On August 31, 2026 that child has already turned 12, so their league age is 12. Two children born just six weeks apart end up in potentially different eligibility bands, purely because of where their birthday falls relative to the cutoff. Running both birthdates through the official calculator on littleleague.org confirms it instantly, which is why the tool is the safest way to check rather than counting on your own.

A note on Little League Softball

This chart covers Little League Baseball. Little League Softball is organised separately and uses its own age-determination date, which is not the same August 31 cutoff. If you are registering for softball rather than baseball, confirm that division’s specific cutoff and age chart directly with your local league or the official site, because applying the baseball date could place your child in the wrong division.

Where the Little League World Series fits

The tournament most families picture, the one broadcast every August, is the Major division, for players with a league age of 10 to 12. That is why you rarely see a very tall or clearly older-looking player: the field is capped at league age 12.

Little League also runs separate World Series events for the Intermediate, Junior and Senior divisions, so older players still have a championship path. But when people say “the Little League World Series,” they almost always mean the 10-to-12 Major bracket.

Why the cutoff exists

A fixed age-determination date keeps every player in a division inside the same competitive age band for the whole season. Without it, children would jump divisions mid-year as birthdays passed, breaking up rosters and schedules.

The cutoff also keeps things fair at the edges. It is not perfect, since a child born just before the date is always the oldest in their group, but it is predictable, and predictability is exactly what a national program with millions of players needs. Rising registration costs and the commitment of a full season make it worth confirming your child’s league age before you sign up, so you know which division and schedule you are agreeing to.

Once your child is playing, the stats they will hear announcers use are the same ones the pros use. Our beginner-friendly explainers on what OPS means in baseball and what a walk-off is are a good way to start talking the game with them.

The short version: your child’s league age is their age on August 31 as of 2026, that number sets their division from Tee Ball up to Senior League, and the televised Little League World Series is the 10-to-12 Major bracket. Always verify the current cutoff on the official site, because Little League sets it and can change it.
