How To Accurately Measure Your Penis Size

Getting an accurate measurement of your penis is crucial for using our Penis Size Calculator effectively. Remember, honesty is key – otherwise, you won’t get a result that you can use for anything.

By following the below steps, you can ensure the data you input into our Penis Size Calculator is as accurate as possible, leading to the most meaningful comparisons.

How To Measure The Length

  1. Tool Required: Use a ruler or a tailor’s tape for this measurement.
  2. Position: Ensure you are fully erect. Position the ruler along the top of your penis.
  3. Method: Press the base of the ruler comfortably against your pubic bone (this is called bone-pressed measurement). Avoid pressing too hard; discomfort means you’re pressing too much.
  4. Special Cases: If you have a significant curve, you have three options:
    • Gently straighten the penis for a linear measurement.
    • Use a string that follows the curve, then measure the string.
    • Measure as is, which gives a different perspective but is still useful. Note that some studies exclude significant curves.

How To Measure The Girth

  1. Tool Required: A tailor’s tape, a piece of string, or a strip of paper can be used.
  2. Method: Wrap your chosen tool around the thickest part of your erect penis. This could be at the base, the middle, or an average of both – there’s no strict rule here. Just avoid measuring around the glans/head.
  3. Reading: Make sure the tape or string is snug but not tight, and read the measurement where it meets.

How To Use The Penis Size Calculator

Step 1: First measure your penis size as described in the section above.

Step 2: The calculator is automatically set to “inches/fl oz”. If you’re more familiar with centimeters then remember to adjust this. See in the picture below how to do that.

Step 3: Insert your number in the field next to “Length”. Just like we did here:

Step 4: Insert the Girth number. See here how to do that:

Step 4 - How to use the calculator

Step 5: The result can be seen in the “overall” row. As you can see above such numbers make the person about 1.10x than the average penis size.

If the number is above 1 so e.g. 1.10 then you have a bigger penis than the average size.

If the number is below 1 so e.g. 0.93 then you have a smaller penis than the average size.

Why Is It Important To Compare Your Penis Size With Others?

Understanding how your penis size compares to others can be more than just a matter of curiosity; it’s about gaining perspective on a topic often shrouded in myths and misconceptions. Let’s explore why this comparison is significant:

Understanding the Average: The average penis size can vary widely depending on factors like genetics, ethnicity, and age groups. By comparing yourself to these averages, you gain a better understanding of where you stand. This knowledge can be especially enlightening when you consider the variations detailed in our comprehensive statistical analysis on penis size statistics.

Biological and Genetic Factors: Penis size is influenced by various biological and genetic factors. Knowing this can help dismantle the common misconception that size is linked to factors like masculinity or sexual prowess. In reality, it’s largely a result of genetic inheritance, much like height or eye color.

Busting Myths: There are numerous myths about penis size affecting sexual satisfaction or correlating with other body parts. By comparing factual data and understanding the average, we can dispel these myths, promoting a healthier body image and sexual confidence.

Educational Purpose: Comparing your size can also serve an educational purpose, helping you understand the wide range of normal variations in human anatomy. This awareness can foster a more accepting and less judgmental view of our bodies.

In summary, comparing your penis size to others is not about competition or self-worth, but about education, busting myths, and developing a healthy perspective on one of the most misunderstood aspects of male anatomy.


Why Size Doesn’t Matter

While the topic of penis size often garners attention, it’s crucial to understand that its significance is far less than many perceive. This section delves into why penis size should not be a dominant concern:

  1. Psychological Impact: The size of one’s penis can disproportionately affect self-esteem and body image. However, it’s important to recognize that these concerns are often amplified by societal standards rather than personal satisfaction or sexual performance. Overcoming these psychological barriers is key to developing a healthier self-perception.
  2. Societal Pressures: Society can impose unrealistic expectations regarding penis size, leading to unnecessary stress and anxiety. Addressing and coping with these pressures involves understanding that sexual satisfaction and compatibility are influenced by a variety of factors, not just physical attributes.
  3. Body Positivity and Self-Acceptance: Embracing body positivity and self-acceptance is essential. Recognizing that each body is unique and deserving of respect helps in building confidence and a positive body image.

For those still interested in exploring options for enhancing penis size, various products are available. Detailed reviews of these products can provide additional insight:

  • For information on penis extenders, which are devices designed to gradually increase penis length, visit our detailed review here.
  • If you’re considering options like cock sleeves, which can enhance size and texture during intercourse, learn more through our comprehensive analysis here.
  • Penis pumps another popular choice for temporary enlargement and erectile dysfunction, are explored in-depth here.

While these products offer ways to modify penis size, it’s vital to remember the importance of self-acceptance and understanding that size is not the sole factor in sexual fulfillment or self-worth.


Our calculator employs a robust and precise methodology to provide accurate measurements and comparisons. We’ve structured our approach into three key areas: Length, Girth, and Volume.

Length and Girth Stats

  • Data Collection: We use a collection of rigorously vetted datasets, ensuring consistency and accuracy in measurement methodologies.
  • Statistical Analysis: Each measurement type (e.g., erect length, girth) is analyzed for its average and standard deviation, along with the total number of samples.
  • Z-Score Calculation: To determine where a specific size stands in relation to the average, we calculate a z-score, a statistical measure indicating how many standard deviations a value is from the mean.
  • Percentile Determination: Assuming a normal (Gaussian) distribution, we use z-scores to accurately determine the percentile ranking of a given measurement.

Volume Stats

  • Cylindrical Approximation: We estimate the volume of the penis using a formula that assumes a perfectly circular girth shape, corrected by a factor to account for real-life variations.
  • Complex Distribution Analysis: Due to the intricate nature of volume distribution, we create a mixture model of generated volume data to calculate the rarity of specific sizes.
  • Pre-calculated Data: Intensive calculations are pre-computed for various volume increments and their corresponding percentiles, ensuring quick and accurate results.

Regional Averages

  • Aggregate Data: We combine multiple datasets to form regional averages, carefully adjusting for sample size and measurement variations. We have in the next section described the datasets we use in more detail.
  • Future Methodologies: We continuously explore new methodologies to enhance the accuracy of our data aggregation, ensuring the most reliable regional averages.
