Handwriting Scales are tools and criteria used by graphologists (people who study and analyze handwriting). Each person has completely unique handwriting, made up of many different characteristics, such as letters shapes, pressure, spacing, slant, etc. With study and practice it is possible to learn a great deal about a person's health, mobility, personality, character, etc. through their handwriting. Although frequently considered a pseudoscience, graphology is sometimes used in business to evaluate potential job candidates.
