Is a 6.7 length x 5.25 inch girth penis above average in the U.S.
Executive summary
A penis measuring 6.7 inches in erect length and 5.25 inches in girth is larger than the averages reported in scientific measurement studies: typical erect length is about 5.1–5.5 inches and typical erect girth about 4.59 inches, making 6.7 inches and 5.25 inches above those central values [1] [2] [3]. Measurement methods and self-reporting bias complicate precise percentile placement, but on the balance of peer‑reviewed and clinical reviews the described size sits clearly above the measured U.S. average [2] [4].
1. What the peer‑reviewed evidence says about “average”
Large reviews and measurement studies that used clinician‑measured methods put the mean erect penis length in roughly the 5.1–5.5 inch range and erect circumference (girth) near 4.59 inches, with one widely cited meta‑analysis giving an average erect length of ~5.16 inches and average erect girth ~4.59 inches [1] [2] [5]. Clinical summaries aimed at patients and professional societies repeat similar figures: a multi‑study analysis reported average erect length ≈5.1 inches and girth ≈4.5 inches [6] [7]. Those are the best estimates to use when comparing an individual measurement to the population baseline [1].
2. Why some U.S. surveys give bigger numbers — and why that matters
Self‑reported US surveys and commercial lists often report higher national averages (for example, a self‑report survey cited a U.S. mean near 6.4 inches), but those results are vulnerable to volunteer and reporting bias and aren’t comparable to clinician‑measured data [8] [2]. Scientific authors repeatedly warn that self‑measurement and internet surveys inflate means because men with larger measurements are likelier to participate or to overstate dimensions, so clinician‑measured meta‑analyses are generally treated as more reliable baselines [2] [4].
3. Placing 6.7 x 5.25 inches against those baselines
Compared to measured‑study averages (erect length ≈5.1–5.5 in; girth ≈4.59 in), a 6.7‑inch length exceeds the mean by about 1.2–1.6 inches and a 5.25‑inch girth exceeds mean girth by roughly 0.6–0.7 inches, which is meaningfully above average though not unprecedented in the population [1] [2] [3]. Available sources do not provide a precise percentile for 6.7 in length or 5.25 in girth using clinician‑measured distributions, so claiming an exact rank (for example “top 5%”) would exceed the reporting provided here [9].
4. Sexual‑preference context and common thresholds
Research that asked women to select preferred erect sizes using 3D models found ideal choices slightly larger than measured averages — roughly 6.3–6.4 inches in length and 4.8–5.0 inches in girth for one‑time partners — putting the 6.7 x 5.25 measurement near or above those stated preferences [10] [11]. Some clinical and industry sources label girths above about 5 inches as “thick,” which would place a 5.25‑inch girth into that category [12].
5. Caveats: measurement standards, variability, and cultural noise
Reliable comparison depends on measuring the erect penis from pubic bone to tip with compression of the fat pad and circumference measured at base or mid‑shaft — procedures used in the more rigorous studies cited here [5] [2]. Geographic, sampling and methodological heterogeneity across studies means there’s natural spread: different studies and regions report somewhat different means and ranges, and no single source in the provided set gives an exact U.S. percentile for a 6.7‑inch erect length [9] [13]. Commercial and promotional outlets sometimes amplify averages for attention or marketing, a bias readers should consider [8] [14].
