Girls flag football enters fall as a sanctioned sport in 17 states

Girls flag football starts its fall season as a sanctioned high school sport in 17 states, with six more voting on sanctioning this year.

The National Federation of State High School Associations, which writes the playing rules for most high school sports in the United States, now lists 17 state associations that have sanctioned girls flag football and 15 more running independent or pilot programs. Six additional states are voting on sanctioning during 2026.

The sport reached that point fast. NFHS participation figures show 42,955 girls played high school flag football in 2023-24, up from 20,875 the season before, a 105% jump in a single year. The organization calls it the fastest-growing emerging sport in American high schools.

Rules caught up with the growth. The NFHS published its first flag football rules book for the 2025-26 season, and its rules committee has since approved eight changes for 2026-27, giving athletic directors a national standard where states once wrote their own. Programs building a first-year roster this fall can custom sports team apparel collection.

"The popularity of flag football, for boys and girls, has been growing at the youth levels for the past 10 years," said Karissa Niehoff, chief executive of the NFHS.

Roughly 500,000 girls ages 6 to 17 played flag football in 2023, according to figures cited by the NFHS, which leaves high school programs a deep pool to recruit from. Flag football also joins the Olympic program at the 2028 Los Angeles Games.

What a first-year program has to buy

A new team is a purchasing problem before it is a competitive one. First-year rosters are small next to a tackle football program, and a school needs jerseys, practice shirts and sideline layers on a schedule set by a season that has already started. Budgets for an emerging sport are rarely large in year one.

That combination, small quantities on short notice, is where traditional apparel suppliers tend to struggle. Case minimums and long production windows are built for established programs ordering the same jerseys every August, not for a school fielding a sport for the first time.

"Schools launching a sport for the first time need the number of jerseys they actually have players for, and they need them inside the season," said Conor Smart, managing director of Arklavo. "Ordering a case and storing the leftovers is the part programs are done with."

Arklavo fills custom apparel orders with no minimum, which means a program can order for the roster it has rather than the case size a supplier prefers. Decoration is handled in house through embroidery, direct-to-garment printing and heat press, with production running two days across Arklavo's custom apparel brands lineup.

Sanctioning changes that math too. Once a state association sanctions a sport, schools run it under standard rules with official schedules and postseason play, and the program becomes a recurring line item rather than a club experiment. Seventeen states have crossed that line, and six more are deciding this year, the same fall stretch when fall sports team stores open earlier as school apparel demand climbs.

The Olympic debut in Los Angeles is still two years out. The rosters that will feed it are being filled this month, in states that had no such teams five years ago. Programs outfitting a first-year squad can request a quote on jerseys, tees and sideline layers sized to the roster they have.
