International Flag Football Rules vs. American High School Rules
A side-by-side comparison of IFAF/Olympic 5v5 flag football rules and NFHS 7v7 rules — field size, timing, rush rules, scoring, and more.
Two Rulesets, One Sport
American high school programs play under NFHS guidelines — typically 7-on-7 on a larger field. Internationally, IFAF governs a 5-on-5 format used at the Olympics. Understanding both is essential for coaches and players operating across environments.
Players on the Field
American high school: seven per side. International: five per side. Fewer defenders means more open space in the international format, favoring speed and one-on-one playmaking. The 7v7 game allows more complex defensive schemes.
Field Dimensions
IFAF: 50 yards long, 25 yards wide, with 10-yard end zones. American high school: typically 80 yards long, 40 yards wide. The narrower international field makes sideline throws riskier and puts a premium on timing routes over the middle.
Timing and Clock
International: two 20-minute halves with a continuous clock, stopping only in the final two minutes. American: varies by state, often four quarters totaling 40-48 minutes with state-specific stop-time rules.
Rush Rule
Both use a seven-yard rush line, but the international format limits rushers more strictly. Some American rulesets allow multiple rushers behind the designated line.
Scoring
Touchdowns are six points in both. International conversions: one point from the 5-yard line, two from the 10. American conversions vary by state — commonly one from the 3-yard line, two from the 10.
FlagStat Supports Both
FlagStat supports both 5v5 and 7v7 formats with built-in rulesets, so coaches maintaining statistical records across both environments get accurate data regardless of format.
