This record is for the greatest difference in the heights of a living set of fraternal twins.
This is to be attempted by two fraternal twins.
This is measured in metres and centimetres, with the equivalent imperial measurement also given in feet and inches.
The record measurement is for the difference between the two heights. Therefore the smaller height must be subtracted from the taller height to give the difference.
For the purposes of the record, fraternal twins are defined as two offsprings resulting from the same pregnancy, usually born in close succession. They can be the same or different sex. Fraternal twins are dizygotic (DZ, colloquially "fraternal" or "nonidentical").
Both members must be older than 18 years old at the time of measurement.
