Abstract The exigency of computational approaches in detection of authenticity of handwriting is currently one of the imperative objective in forensic investigation. The most common pending errors made during investigation process are the utilisation of only known conventional methods of examination. The study was conducted with the objective of determining the range of natural variation in handwriting considering a period crevice of every two years. The instability of the factor, “Size and Proportion” of letters served as an indicator. Samples were collected at time intervals of two years irrespective of age from 20 individuals. “Autodesk Computer Aided Drafting” software was used to set the range of natural variations. The unique detectable range of natural variation after two years, then four years and finally after 6 years in genuine writing was found. The technique helps in solving the cases aiing in contemporary writings and could be served as a non-destructive method of examination.
