Abstract

Handwriting is a complex motor activity influenced by various physiological and biomechanical factors, among which handedness plays a crucial role. The present study aims to examine and compare the handwriting characteristics of right- handed and left-handed individuals in order to identify distinguishing features of forensic significance. A total of 100 handwriting samples were collected, including 50 from right-handed participants and 50 from left-handed participants. The samples were analysed based on selected handwriting parameters such as alignment, slant, spacing, connecting strokes, size of letters, and margin. The results of the study indicate noticeable variations between right-handed and left-handed writers across the examined parameters. These variations can be attributed to differences in writing posture, hand movement, and motor coordination associated with handedness. The findings highlight the importance of handwriting characteristics as supportive indicators in determining the handedness of a writer. In conclusion, the study emphasizes that handedness has a measurable influence on handwriting characteristics, contributing to individual writing patterns.
