Is 5 in of girth small, average, or big?

5 in girth (12.7 cm) is above average: it measures more than 83% of men in the 2015 Veale et al. review of 15,521 men (global erect girth mean 11.7 cm, SD 1.1 cm).

What percentile is 5 in of girth?

5 in girth (12.7 cm) lands at about the 83% percentile — top 17%, meaning roughly 17% of men measure more.

Is 5 in of girth 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 5 in girth (12.7 cm) you are above average, which the data shows is firmly within the range partners consider normal.

The Data Answer

Is 5 in girth enough?

5 in girth (12.7 cm), measured against the global distribution from the largest review to date (Veale et al. 2015, n = 15,521).

Thicker than 83% of men

Average

That puts 5 in girth (12.7 cm) in the top 17% — 17% of men measure more.

Clearly above average

This is beyond the +1 SD line — a minority of men measure this or more. Outside the statistical noise, this is where 'big' starts being a defensible label.

Sky line: your measurement. Dashed line: baseline average. Bands: size tiers by standard deviation.

The number in perspective

Above the compiled national average in 127 of 134 countries we track.
In a room of 1,000 men, about 172 measure more.
Only 68.27% of men fall inside the Average band (−1 to +1 SD of the mean).

Context

The global erect girth mean is 11.7 cm (4.6 in) with SD 1.1 cm — two thirds of all men fall between roughly 10.6 and 12.8 cm (4.2–5.0 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.
Girth — not length — decides condom fit: the condom size calculator converts your girth into the right nominal width.
What partners actually care about is a different (and much-cited) dataset — does size matter to partners?
