How did the Kinsey researchers measure penis size?

Men were asked: "How long is your penis, measuring on the acme side from your abdomen out to the tip?" They were each given a pre-stamped card to take home, and instructed to marking the length on the menu when flaccid and when erect. Approximately 2,500 men participated.

During interviews with over 4,000 men, the interviewer asked each field of study to estimate his penis size. The interviewer would hold out a ruler (the numerals were not visible to the subject) and move his finger along information technology.

At that place was a slight underestimation of penis size compared with actual measurements.
(Gebhard & Johnson 1979, p. 116.)

What is the human relationship betwixt the size of a flaccid (soft) penis and an erect (hard) penis?

In that location is a much wider range of size in men'south penises when flaccid, with the average ranging from 1 to 4 inches. In full general, smaller, flaccid penises lengthen at erection by a greater per centum than larger, flaccid penises, with most men reaching an average size of 5 to 7 inches.

Surgery may cause scar tissue to grow that can crusade a painful or fifty-fifty a shortened erection.
