Quick Scoop: Size 5 Football Circumference

For a regulation, adult match ball used in professional and most amateur competitions:

• Circumference: 68–70 cm (≈ 27–28 inches).

• This range is set by major governing bodies (like FIFA-style standards) to ensure consistent flight, bounce, and feel across all official games.

If you measure around the fattest part of your ball with a tape measure and it lands in that 68–70 cm window, you’re holding a true size 5 official football.
