This record is for the greatest difference in the heights of a living set of fraternal twins.
This is to be attempted by two living male fraternal twins.
This record is measured in centimetres (cm) to the nearest 0.1 cm, with equivalent imperial measurements also given in inches (in).
For the purposes of the record, fraternal twins are defined as two offspring from the same pregnancy. They can be the same or different sex. Fraternal twins are dizygotic (DZ, 'fraternal' or 'nonidentical twins'). Monozygotic (MZ, 'identical twins') are measured under another title.
