6.7 inches in length and 5.5 inches in girth considered above average or big for size

1. How scientists define “average” and why it matters

Researchers use medically measured samples and systematic reviews to estimate averages because self-reports tend to inflate size; a prominent 2015 review and other summaries place mean erect length roughly between 5.1 and 5.5 inches (13–14 cm) and mean erect circumference (girth) around 4.6–4.8 inches (11.7–12.2 cm) ^{[3] [1] [2]}. Those benchmarks, not internet anecdotes, form the basis for saying whether a particular measurement is “above average,” because they rely on thousands of measured men rather than self-measurement bias ^[3].

2. Where 6.7" length and 5.5" girth fall on the curve

The reported consensus puts a 6.7‑inch erect length clearly above the mean; studies show most men cluster between roughly 4.5–5.8 inches and 95% fall between about 3.9 and 6.5 inches in at least one large review, which makes 6.7" outside or near the extreme upper tail depending on the dataset ^{[5] [3]}. Girth of 5.5 inches compares to typical girth averages near 4.6–4.8 inches; that amount of circumference is noticeably above average by the same reviews and preference studies ^{[2] [4]}.

3. What “big” means in published research and public perception

Scientific studies frame “big” relative to statistical percentiles; one clinician summary says a 6‑inch penis sits near the 85th percentile for length—so 6.7" would be rarer still—while girth preferences and measurements in small studies show many women prefer slightly above the population mean (around 6.3" length and ~4.8" girth in a 75‑participant 3D‑model study) ^{[5] [4]}. Media and specialty sites often translate these percentiles into plain language—“above average” or “large”—but exact labels vary by source ^{[6] [7]}.

4. Sexual function, partner preference, and the limits of size talk

Multiple sources report that girth sometimes matters more than length for perceived sexual satisfaction, and that partner preferences vary; a 3D‑model study of women showed preferences slightly above average for one‑time and long‑term partners, especially for circumference ^{[8] [4]}. At the same time, clinical reviews emphasize that most partners prioritize factors beyond raw size and that sexual satisfaction does not correlate simply with larger measurements ^{[1] [9]}.

5. Measurement caveats and potential sources of error

How you measure matters: professional studies measure from pubic bone to tip with pubic fat compressed and girth measured at mid‑shaft or base; self‑measurement and online surveys typically overstate length by about 0.5 in (1.3 cm) or more, which can shift where a given number falls relative to the population mean ^{[3] [10]}. Available sources do not mention your measurement method or whether your numbers were professionally recorded.

6. What the numbers imply for someone asking “above average or big?”

Given the best available summaries, 6.7 inches in length and 5.5 inches in girth are both above the commonly reported population means and would usually be described as larger than average—often “large” in popular terms—because the population distribution is relatively narrow around the mean ^{[1] [3] [5]}. Different studies and popular sites translate that into percentiles and everyday language, but they converge on the conclusion that your dimensions are greater than what most datasets call typical ^{[3] [7]}.

Limitations and disputes in the record: studies differ by sampling method, geography, and whether measurements were self‑reported or clinically taken; some sources (e.g., country rankings built from self‑reports) produce higher national averages and must be interpreted cautiously ^{[10] [11]}. When precision matters, rely on medically obtained measures and peer‑reviewed reviews rather than self‑report or rankings with heavy adjustments ^{[3] [10]}.
