Fingerprint patterns form within the first eighteen weeks of fetal development and remains unchanged throughout a person’s life. Each fingerprint is unique yet is classifiable into one of three basic patterns: the loop, the arch, and the whorl. These patterns are indicative of personality traits.

Fingerprints are not like the other lines in the palm. They fall under the science of dermatoglyphics, the study of ridges of the skin, a word derived from the Greek derma, meaning “skin” and glyptos, meaning “carvings or engravings”.

The lines of the hand, which are noted for their ability to change, are in stark contrast to the dermatoglyphic ridges that remain constant. It is this aspect of permanence that makes it possible to use fingerprints in crime detection.
Physiologically, the ridges of the skin are made for gripping objects. They serve as channels for sweat glands and facilitate the sense of touch. The ridges are formed by a thickening of the skin both above and below the epidermis. On hands with medium-grade or coarse skin the fingerprint patterns are often easily visible to the eye. Viewing fingerprint patterns on hands with fine skin may require a magnifying glass.

When we look at fingerprints there are some important considerations to take into account. Although fingerprints fall into three basic categories (Loop, Arch, Whorl), there will be variations within each.


THE TRIRADIUS: Although fingerprints are classified by their shape, they are also identified by the presence and number of triradii. A triradius is a small, three sided triangular form created by intersecting ridge patterns. A triradius forms where the ridges of the primary fingerprint pattern meets with other dermatoglyphic currents. This triangular pattern is easy to spot with a magnifying glass. The number of triradii helps to identify the fingerprint pattern. SIMPLE ARCHES have no triradius. TENTED ARCHES have one triradius at the centre of their base. LOOPS also have one triradius that is slightly off-center. WHORLS have two triradii at the base of the pattern, often balanced on the bottom left & right edges. When a fingerprint is a COMPOSITE of two different patterns it is often the number of triradii that will let you know into which category the fingerprint falls.


MIX-AND-MATCH FINGERPRINTS: It is rare that people will have the same fingerprint pattern on all ten fingers. Uniform prints on every finger occur in less than 10 percent of the population. When the patterns are the same on all ten fingers the person will be an extreme version of the pattern type; the characteristics associated with the pattern will have a strong impact on her or his personality. Most hands are composed of a variety of different fingerprint patterns, although there is often a majority of one type. When the fingerprints are varied, the personality traits associated with the fingerprint pattern are applied to the specific finger and its mount. It is natural for people to vary in their approach and attitude toward different areas of their lives. The fingerprint reflects how the person approaches the interests and concerns of the specific finger and mount.


The fingerprints on both the dominant and recessive hand are equally important. As with the lines in the hand, the meaning of the fingerprints alters slightly depending on which hand they appear. The dominant hand shows the person’s predominant behaviour and the active day-to-day attitudes. The recessive hand shows the subconscious instincts.


It is interesting to compare the matching fingers on both hands; for example, the two Jupiter fingers, the two Saturn fingers, and so forth. Fingers act as pairs; either finger of a pair can heighten, restrict, or modify the way the characteristics of a given pattern will manifest. For example, if two Jupiter fingers have the same pattern you can rest assured that the qualities of that pattern are strongly exhibited in the areas of life governed by Jupiter. If the fingerprint patterns differ the result will be a blend or modification of the two inclinations
