Is 4 in small, average, or big?

4 in (10.2 cm) is below the global average: it measures more than 3.7% of men in the 2015 Veale et al. review of 15,521 men (global erect length mean 13.1 cm, SD 1.7 cm).

What percentile is 4 in?

4 in (10.2 cm) lands at about the 3.7% percentile — top 96.3%, meaning roughly 96.3% of men measure more.

Is 4 in enough for a partner?

Partner-preference studies (e.g. Lever 2006, Prause 2015) consistently rank size far below what men assume — most partners place it well behind factors like attentiveness and confidence. At 4 in (10.2 cm) you are below the global average, which the data shows is firmly within the range partners consider normal.

The Data Answer

Is 4 in enough?

4 in (10.2 cm), measured against the global distribution from the largest review to date (Veale et al. 2015, n = 15,521).

Longer than 3.7% of men

Modest

That puts 4 in (10.2 cm) in the top 96.3% — 96.3% of men measure more.

Below average — and that is a distribution fact, not a verdict on you

This sits in the lower quarter of the global distribution. Two honest points: percentile is a position in a queue, not a grade, and partner studies consistently rank size far below what men assume. The guides below cover both, with sources.

The number in perspective

Above the compiled national average in 0 of 134 countries we track.
In a room of 1,000 men, about 963 measure more.
Only 13.59% of men fall inside the Modest band (−2 to −1 SD of the mean).

Context

The global erect length mean is 13.1 cm (5.2 in) with SD 1.7 cm — two thirds of all men fall between roughly 11.5 and 14.8 cm (4.5–5.8 in).
Percentiles assume a correct measurement: bone-pressed, fully erect, top side. Technique changes the number by up to 2 cm — see how to measure.
What partners actually care about is a different (and much-cited) dataset — does size matter to partners?
