Uniqueness

Each person has their own unique style of handwriting, whether it is everyday handwriting or their personal signature. Cultural environment and the characteristics of the written form of the first language that one learns to write are the primary influences on the development of one's own unique handwriting style.Sargur Srihari, Chen Huang and Harish Srinivasan (March 2008)
"On the Discriminability of the Handwriting of Twins"
''J Forensic Sci.''; 53(2):430–46.
Even identical twins who share appearance and genetics do not have the same handwriting. Characteristics of handwriting include: * the specific shape of letters, e.g. their roundness or sharpness * regular or irregular spacing between letters * the slope of the letters * the rhythmic repetition of the elements or arrhythmia * the pressure to the paper * the average size of letters * the thickness of letters


Medical conditions

Developmental dysgraphia is very often accompanied by other learning disabilities and/or neurodevelopmental disorder like ADHD. Similarly, people with ADD/ADHD have higher rates of

have been found to be more likely to have less legible handwriting, make more spelling errors, more insertions and/or deletions of letters and more corrections. In children with these difficulties, the letters tend to be larger with wide variability of letters, letter spacing, word spacing, and the alignment of letters on the baseline. Variability of handwriting increases with longer texts. Fluency of the movement is normal but children with ADHD were more likely to make slower movements during the handwriting task and hold the pen longer in the air between movements, especially when they had to write complex letters, implying that planning the movement may take longer. Children who have ADHD were more likely to have difficulty parameterising movements in a consistent way. This has been explained with motor skill impairment either due to lack of attention or lack of inhibition. To anticipate a change of direction between strokes, constant visual attention is essential. With inattention, changes will occur too late, resulting in higher letters and poor alignment of letters on the baseline. The influence of medication on the quality of handwriting is not clear.
