how many schools in big 10

There are 18 schools in the Big Ten Conference as of the 2024–25 and 2025–26 seasons.

Quick Scoop: Big Ten Size

• The Big Ten kept its traditional name even as it expanded well beyond 10 members over the years.

• The league reached 18 full member universities after adding Oregon, UCLA, USC, and Washington in the 2024 realignment wave.

Why people get confused

• For a long time, the Big Ten actually had 10, then 11, then 12, then 14 members, so older fans still associate it with those numbers.

• Recent realignment has been fast and messy, so older articles or casual blogs may still list 14 schools, even though the conference now stands at 18.

Extra context

• The current 18 Big Ten schools stretch from New Jersey and Maryland on the East Coast all the way to Washington and Oregon on the West Coast.

• In addition to the 18 full members, the Big Ten also has a small number of affiliate members in specific sports, but when people say “how many schools in the Big 10,” they almost always mean the 18 full members.

TL;DR: The Big Ten name is misleading now — there are 18 member schools, not 10 or 14.
