Slant is the predominant angle of the
downward stroke in handwriting based on
Latin script
The Latin script, also known as the Roman script, is a writing system based on the letters of the classical Latin alphabet, derived from a form of the Greek alphabet which was in use in the ancient Greek city of Cumae in Magna Graecia. The Gree ...
. The slant of a sample of writing is a feature of many
regional handwriting variations, and also a reflection of the
copybook that is taught.
Examples
* Slant is measured in degrees counterclockwise from the base line;
* A slant of less than 90 degrees is a right-hand slant;
* A slant of more than 90 degrees is a left-hand slant. (No examples in the above table.)
Measurement of slants
A good basis for its estimation is the point of the handwritten curve where the velocity has its peak value in the downward stroke. The
polar distribution of the
running angle along a handwritten trajectory is another good method for estimating the slant angle. Left-handed writing is often accompanied by a slant value which is larger than 90 degrees, i.e., it is bent backward, to the left.

graphology
Graphology is the analysis of handwriting in an attempt to determine the writer's personality traits. Its methods and conclusions are not supported by scientific evidence, and as such it is considered to be a pseudoscience.

slant can refer to either upstroke or downstroke values. These strokes can be made in the upper, middle, lower, or any combination of those zones.
