replace this page with the diagram of the field markings
These notes accompany the field diagram as a summary of requirements for the marking of the field. For full details see Rule 1-2.
1 yard = 3 feet = 36 inches = 91.44cm
1 foot = 12 inches = 30.48cm
1 inch = 2.54cm
1 yard = 36 inches (91.44cm), but may be shortened to no less than 34.12 inches (86.67cm) only if necessary to fit a 100-yard field of play plus two 10-yard end zones within the available playing surface. If the length of the field is reduced in this way, all other field dimensions and markings stated in the rules must be reduced commensurately.
