This peni size calculator allows you to compare physical measurements against global clinical datasets. It provides a percentile ranking based on peer-reviewed urological studies to help you understand where your measurements sit on the statistical distribution.

Peni Size Calculator Formula
Where $x$ is the input, $\mu$ is the mean, and $\sigma$ is the standard deviation.
Formula Source: Calculations are based on the meta-analysis published in the British Journal of Urology International (BJUI).
Variables:
- Flaccid Length: Measurement of the non-erect organ from the pubic bone to the tip.
- Erect Length: Measurement when fully engorged.
- Erect Girth: The circumference measured at the thickest part of the shaft.
- Standard Deviation ($\sigma$): The variance from the average found in clinical cohorts.

What is the Peni Size Calculator?
A peni size calculator is a statistical tool used to determine how a specific set of physical measurements compares to a broader population. Rather than providing a simple “pass/fail” metric, this calculator uses Z-score distribution logic to find your percentile ranking.
Most users utilize this tool to alleviate anxiety regarding anatomical variations. By referencing clinical data rather than anecdotal evidence or adult media, the tool provides a grounded, scientific perspective on human physiology.
How to Calculate Peni Size (Example)
- Measure the erect length from the pubic bone to the tip.
- Suppose the measurement is 13.12 cm.
- Reference the BJUI mean for erect length ($\approx 13.12$ cm) and standard deviation ($\approx 1.66$).
- Apply the Z-score formula: $(13.12 – 13.12) / 1.66 = 0$.
- A Z-score of 0 corresponds to the 50th percentile (exactly average).
Frequently Asked Questions (FAQ)
Is this calculator private? Yes. All calculations are performed locally in your browser; no data is sent to any server.
What is considered “average”? Based on medical meta-analyses, the average erect length is approximately 13.12 cm (5.16 in).
How accurate is the percentile? The percentile is as accurate as the underlying study (Veale et al.), which involved over 15,000 subjects.
Should I measure from the bone? Yes, clinical standards require measuring from the pubic symphysis (pressing into the fat pad) to ensure consistency.
