Types of Fingerprints

Central Pocket Whorl
Central Pocket Whorl

Central pocket loop whorls consist of at least one re-curving ridge or an obstruction at right angles to the line of flow, with two deltas, between which when an imaginary line is drawn, no re-curving ridge within the pattern area is cut or touched.

Double Loop Whorl
Double Loop Whorl

Some double loops look more like whorls, others are more clearly two intertwined loops. Depending on which one it is, see also the associated loop or whorl characteristics. Peacock's eye (a.k.a. central pocket loop): perfectionistic, good eye for detail. It is more of a whorl than a loop, so see also whorl characteristics.

Plain Arch
Plain Arch

The plain arch is the simplest of the fingerprint patterns to discern. Tented Arch---this pattern is similar to the plain arch in that it starts on one side of the finger and flows out in a similar pattern to the other side.

Plain Whorl
Plain Whorl

Whorls are seen in about 25-35 % of fingerprint patterns encountered. In a whorl, some of the ridges make a turn through at least one circuit. Any fingerprint pattern which contains 2 or more deltas will be a whorl pattern. There are four types of whorl patterns.

Radial Loop
Radial Loop

Radial loop fingerprints are characterized by a flow of the pattern that opens in the direction of the radius (or thumb side of the hand) featured with a triradius located at the ulna (pinky) side of the hand.

Tented Arch
Tented Arch

The tented arch and the arch comprise about 5% of fingerprint patterns found on the human finger tips and thumbs. The tented arch has a ‘tent pole’ thrusting up from the mound at the base in the middle of the print. See the example below.

Ulnar Loop
Ulnar Loop

Loops occur in about 60-70 % of fingerprint patterns encountered. One or more of the ridges enters on either side of the impression, re-curves, touches or crosses the line running from the delta to the core and terminates on or in the direction of the side where the ridge or ridges entered. Each loop pattern has is one delta and one core and has a ridge count. Radial loops are named after the ...
