A Swiss graphologist Walter Hegar studied lines in handwriting. He thought that a line is something you can’t control, hence it can give the most reliable and full description of personality. In his book published in 1930, Hegar provided 24 personality descriptions that, according to his studies, can be singled out through the nature of lines in writing.
A type of stroke (curves, lines) is defined by 4 factors: pressure, quality, movement, speed.
The pressure of the stroke can tell how a person perceives reality, how he would find solutions to tasks and issues.
Pressure can be heavy and light (strong and weak). A heavy pressure means decisiveness and energy, a light stroke represents a weak and sensitive personality. The type of the stroke can be defined by the way it is imprinted on the back side of the sheet and thickness of the line (in case of a dip pen or a rapidograph).
The quality of the stroke is defined by a precise or pasty line. When analysing this factor, letters are studied under a microscope, and the attention is focused on the side of the line — it can be smooth and clean or edgy and blurred.
The quality of a stroke describes the person’s activity levels and the way of thinking. A precise line means a person is decisive and active, lives according to clear rules and doesn’t give himself a break. A pasty and hazy writing shows a person’s weak self-discipline, unwillingness to be stressed, blurred boundaries and unclear principles in life.
Movement of the stroke is defined by the form of the line. Writing can be straight and edgy or curved and round. The form of lines shows how independent a person is, if he or she can make decisions and can be a master of his own fate.
Straight and edgy writing shows a direct and rigid personality, totally independent, decisive, and ability to take important decisions. If the writing has mainly curve lines with a lot of round and oval shapes, the author of the text is on the contrary soft and even spineless, indecisive and dependent.
The speed of writing shows how dynamic a person is. A rapid writing differs from the slow one by the connections between letters, the slant; letters are harmoniously connected with each other. A rapid writing means a person is dynamic, learns quickly, takes decisions immediately, and easily switches tasks. Slow writing means a person has a wait and see attitude and is cautious.
Different combinations of the above characteristics can form 24 different types of personality.
