The handwriting of all persons changes progressively and steadily with the passage of time. The extent of the change will depend on a number of factors: the amount of writing experience, the state of the physical and mental health of the writer, and the growing age of an individual. In the present study a total of 90 handwriting samples from 6 different age groups ranging from 10 to 50 years above were collected from males (Indian). The subjects were asked to write London letter on Blank A-4 sheet. The handwriting samples were analyzed to extract out the specific class and individual characteristics selected for the study. A coding has been formulated for class characteristics for the research for simplification and conveying results. Handwriting samples have been coded for class characteristics. Subsequently, percentage proportions of the class characteristics have been calculated. For each class characteristic category coding has been performed and results in the form of percentage have been calculated. The result individually for each age group has been discussed. The class characteristics such as slant, alignment, speed, spacing and tremors has varied in percentage for different age groups by making a fine demarcation between the age groups. Not conclusively with full surety but probable assessment can be done of age from the findings of this research. By considering the findings of present study one can form a rough idea regarding the age of writer (male) so as to proceed and take initiative in a case. This research work can also be used as to escape out the innocent with the help of other corroborative evidences.
