Reduced Endzones

Causes for Ultimate fields being short may be: 1) the person who setup the field paced it off incorrectly, or 2) endzones are meant to be 20 yards.

Endzone Size - Endzone length will be shortened to 20 yards. This change allows for consistency with WFDF rules in international competition and increases the number of field sites that an be used for ultimate.
