Types of fingerprint patterns
- Loops. The fingerprint patterns falling under the loop category can be easily seen in 60%-70% of the encountered fingerprints.
- Arches. The fingerprints that contain arches occur in approximately 5% of the fingerprints. ...
- Whorls. The whorls patterns are found in almost 25-35 % of fingerprint patterns that are found at the crime scenes.
What determines your fingerprint pattern?
What determines your fingerprint? A person’s fingerprints are based on the patterns of skin ridges (called dermatoglyphs) on the pads of the fingers. Genes that control the development of the various layers of skin, as well as the muscles, fat, and blood vessels underneath the skin, may all play a role in determining the pattern of ridges.
What are the three fundamental principles of fingerprints?
What are the three principles of fingerprints?
- Arches. In this pattern type, ridges enter on one sides and exit on the other side.
- Loops. This pattern type has ridges entering on one side and exiting on the same side.
- Whorls. Consists of circles, more than one loop, or a mixture of pattern type.
Which fingerprint pattern is seen less frequently?
The next most common type of pattern was the whorl, which accounts for about 20 percent of all prints. The least common type of print is the ridge, which only accounts for about 10 percent of all prints.
What are the basic fingerprint patterns?
All fingerprints can be classified into three basic patterns: loops, whorls, and arches.
How many types of fingerprints pattern are there?
threeFingerprints The fingerprints may be categorized into three general pattern types: - arches, Loops and Whorls. The common characteristics that make up these patterns are known as pattern area, type lines, delta and core.
What are the most common types of fingerprints?
Loop. The loop is the most common type of fingerprint. The ridges form elongated loops. Some people have double loop fingerprints, where the ridges make a curvy S shape.
How many standards fingerprint pattern are there?
There are three main fingerprint patterns, called arches, loops and whorls. The shape, size, number and arrangement of minor details in these patterns make each fingerprint unique.

What are the different types of fingerprint patterns explain each?
There are four groups of whorls: plain (concentric circles), central pocket loop (a loop with a whorl at the end), double loop (two loops that create an S-like pattern) and accidental loop (irregular shaped). Whorls make up about 35 percent of pattern types.
What are the 8 fingerprint types?
The Federal Bureau of Investigation (FBI) recognizes eight different types of fingerprint patterns: radial loop, ulnar loop, double loop, central pocket loop, plain arch, tented arch, plain whorl, and accidental. Whorls are usually circular or spiral in shape.
What are the 3 main types of fingerprints?
Although every fingerprint is different, they're all variations on three broad categories: the arch, which looks a bit like a cross-section of a hill; the loop, which is teardrop-shaped; and the whorl, which is reminiscent of a whirlpool.
What is the most rare fingerprint pattern?
The Arch1: The Arch. This is the rarest type of fingerprint. In fact, about 5% of the world's population have this fingerprint pattern. Its lack of cores, lines or deltas makes it unique.
Who identified 9 fingerprint patterns?
Jan PurkinjeIn 1823, another physiologist, Jan Purkinje, noted at least nine different fingerprint patterns. The pioneer in fingerprint identification was Sir Francis Galton, an anthropologist by training, who was the first to show scientifically how fingerprints could be used to identify individuals.

Who is the father of fingerprint?
26. 1901-Sir Edward Richard Henry was appointed assistant commissioner at Scotland Yard. His system was so applicable that Henry emerged as the “Father of Fingerprints,” at least as the first man to successfully apply fingerprints for identification.
What are the 3 most common of fingerprint patterns?
(Research) There are three types of fingerprints The three types of fingerprints are Whirls, loops, and ridges. We found that the most common one was the loops with sixty to sixty five percent. We also found out that whirls is the next common fingerprint with thirty to thirty five percent.

What are the four types of finger print?
Using advanced Henry method, the main types of fingerprints were classified as arch, loop, whorl, as well as other types.
How are fingerprint patterns determined?
The fingerprint patterns are determined by the arrangements of the ridges formed by the distal phalanges of the finger. The fingerprint patterns categorized into different types based on the shapes, lengths, joining and turnings.
What is the type of line in fingerprints?
TYPE LINE: In fingerprint patterns, the outermost line of the encloses pattern area, delta, core. These are well defined as the two innermost ridges starting parallel or run parallel to each other then diverge and tend to cover the pattern area.
What is a double loop pattern?
The pattern is made by either overlapping or surrounding one another and both the loops after terminating exiting from the both sides of the delta. one loop exiting from left side and one from right side.
What is the study of fingerprints called?
A fingerprint is a sway left by the friction ridges of a person’s being. The study of fingerprint impressions is known as Dactyloscopy.
What is the name of the ridges that run from one side of the print to another side?
1. ARCH: the ridges run from one side of the print to another side forming an arch like formation.
What is accidental pattern?
ACCIDENTAL: A pattern, which does not fall under the above types, are called accidental. It is a combination of any two different patterns except one of the pattern is plain arch. Such patterns must consist 2or more than 2 deltas.
Which shape has at least one ridge forming complete trip?
It has at least one ridge forming complete trip may be in the form of spiral, oval, circle.
What are the three basic fingerprint patterns?
Types of fingerprint patterns. Edward Henry recognized that fingerprints could be described as having three basic patterns – arches, loops and whorls . These shapes and contours were later sub-divided into eight basic patterns and are used by the FBI till today.
What is the pattern of fingerprints?
In this pattern a consistency of flow can be observed. It starts on one side of the finger and the ridge then slightly cascades upward. This almost resembles a wave out on the ocean and then the arch continues its journey along the finger to the other side. The plain arch pattern is the simplest of the fingerprints to discern.
How many shoulders does a loop pattern have?
This pattern consists of two distinct and separate loop formations. It has two distinct and separate shoulders for each core, two deltas and one or more ridges that make a complete circuit. There is at least one re-curving ridge within the inner pattern area between the two loop formations that gets touched or cut when an imaginary line is drawn.
What is the simplest form of whorl?
The ridges in these whorls make a turn of one complete circuit with two deltas and are therefore circular or spiral in shape. This is the simplest form of whorl and also the most common.
How do criminal investigators identify murderers?
Most of us might have wondered how criminal investigation agencies identify murderers with the help of their fingerprints and what the process entails. To put it simply, they look at the patterns of fingerprints. These patterns are little ridges on the end of an individual’s fingers and thumb that are arranged in a pattern of spirals and loops. Nature has evolved these patterns in such a manner that it helps humans to grip and hold onto things. Moreover, the texture prevents things from slipping and sliding that would have naturally happened if the skin was smooth.
Where is the radial loop on the index finger?
The flow of these loops runs in the direction of the radius bone i.e. the downward slope of the radial loop is from the little finger towards the thumb of the hand. These loops are not very common and most of the times will be found on the index fingers.
When did fingerprints become permanent?
These patterns are formed during the 12th week of gestation and remain permanent throughout a person’s life. With this discovery that fingerprints are a unique method of identifying individuals, Sir Francis Galton first introduced the technique of comparing prints found at a crime scene with those of the suspect. Later, Sir Edward Henry developed the system of classifying fingerprints that was first adopted as the official system in England which eventually spread throughout the world.
