How rare is a whorl fingerprint?
about 25 to 35\%
Whorls. These can be found in about 25 to 35\% of the fingerprints that are encountered. Some of the ridges in a whorl make a turn through at least one circuit. Therefore any pattern that contains two or more deltas will be a whorl.
What is a whorl pattern?
A whorl is a type of spiral or circular pattern. Other meanings of whorl include: Whorl (botany), the attachment of sepals, petals, leaves, or branches at a single point. Whorl (biology), the structure of some organs, used in the aid of identification. Storiform pattern in histopathology.
What are the characteristics of whorl fingerprint?
Whorls are circular or spiral and are the second most common characteristic. Whorls come in four types: plain, pocket loop, double loop, and accidental loop. Each is named for the shape of the whorl. Arches are the third and least common fingerprint characteristic.
What are the 4 types of whorls?
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)
- Accidental loop (irregular shaped).
What percent of the population has whorl fingerprints?
Loops are the most common type of fingerprint; on average 65\% of all fingerprints are loops. approximately 30\% of all fingerprints are whorls, and arches only occur about 5\% of the time. There are subcategories for each of these.
How do you trace a whorl fingerprint?
A whorl – type pattern which has been fully rolled from nail to nail either side, will be given the tracing of the opposite finger and referenced to the two other tracings. If the opposite pattern is not a whorl, the whorl – type pattern will be classified as a meet tracing and referenced to an inner and outer tracing.
How do people identify finger prints?
How is fingerprint identification implemented?
- A picture is taken of the fingerprint.
- The fingerprint is then transformed into a numerical model which stores the fingerprint’s unique characteristics, such as the arches and loops and their distance from each other, as a series of numbers.

How rare is an arch fingerprint?
5\%
1: The Arch. Plain Arch – Raised ridges characterize this pattern and they extend from one side of the finger to the other in a continuous fashion. This pattern makes up a mere 5\% of the total population, making it the rarest type.
