Handwriting refers to a person's writing created with a writing utensil such as a pen or pencil. The term encompasses both printing and cursive styles and is separate from formal calligraphy or typeface.

Because each person's handwriting is unique, it can be used to verify a document's writer, and the deterioration of a person's handwriting is also a symptom or result of certain diseases.

Uniqueness of handwriting[edit]

Each person's handwriting is unique. Even identical twins write differently.[1] A person's handwriting is also relatively stable and changes little over time.[citation needed]

Characteristics of handwriting include:

  • 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

Uses of handwriting samples[edit]

Because handwriting is relatively stable, a change in the handwriting can be indicative of the nervousness or intoxication of the writer.[citation needed]

A sample of a person's writing can be compared to that of a written document to determine and authenticate the written document's writer; if the writing styles match, it is likely that one person wrote both documents.

Graphology[edit]

Graphology is the pseudoscientific[2][3] study and analysis of handwriting in relation to human psychology. Graphology has been used in the medical field as an aid in diagnosis and tracking of diseases of the brain and nervous system, though such use is highly controversial.[citation needed]
