The most suitable instrument to measure the circumference of a football is a tape.

  • A tape diameter, or d-tape, is the most common device for the measurement of the ball's circumference.
  • The ball is enclosed with the tape, and is graduated to reflect a transition from the ball circumference diameter, thus measuring the circumference.
  • It can also be measured by a micro metre which is installed on a three point mount is a sphereometer.
  • The length of the chord on the sphere is defined by three points and the micro metre by the partial radius of the surface above the chord. To calculate the actual radius, a set of supplied tables, or a formula, is employed.
