Last Updated: July 2026
Whether you're curious about your measurements, comparing yourself with published averages, or tracking long-term progress, measuring correctly is extremely important.
Unfortunately, many people unknowingly use inconsistent methods that can produce different results each time. .
This guide explains those methods in simple language, highlights common mistakes, and shares the same measurement routine I've used throughout my own PHALLOSAN forte journey.
Quick Answer
For the most consistent results:
- ✔ Measure while flaccid ( we will utilize Phallosan Forte bell to extend and measure your penis in the flaccid state).
- ✔ Use a rigid ruler for length.
- ✔ Measure from the side of the public bone to the tip of the penis (bone-pressed method) if you want results that are comparable with most clinical research.
- ✔ Use a flexible measuring tape for girth.
- ✔ Measure under similar conditions each time.
Why Accurate Measurements Matter
Measuring isn't about chasing a bigger number.
It's about obtaining a measurement that is consistent and meaningful.
Accurate measurements can help you:
- Compare your size with published scientific averages.
- Track changes over time using the same method.
- Record progress consistently if you're using PHALLOSAN forte.
- Avoid confusion caused by changing measurement techniques.
The most important rule is simple:
Use the same method every single time.
Why Two People Can Get Different Numbers
One of the biggest sources of confusion is that different people measure in different ways.
For example, one person may measure from the skin at the base of the penis, while another measures from the public bone.
Those two methods can produce different results even if both people have identical anatomy.
That's one reason clinical research often uses the bone-pressed method—it provides a more standardized reference point.
Important: Whatever method you choose, use the same technique every time you measure. Consistency is far more important than trying to maximize the number.

Preparing Measurements for PHALLOSAN forte APP
If you're measuring before using PHALLOSAN forte or recording progress in the tracking app, a little preparation makes the process much easier.
I recommend following these steps every time.
Converting Inches to Decimals
If you're entering your measurements into the PHALLOSAN Tracking App, you'll notice that the app expects decimal values rather than fractional inches.
For example, if your ruler reads 6¼ inches, you'll need to enter 6.25.
This is a simple conversion, but it's something that often confuses first-time users.
Common Fraction-to-Decimal Conversions
| Fraction | Decimal |
|---|---|
| 1/8 | 0.125 |
| 1/4 | 0.25 |
| 3/8 | 0.375 |
| 1/2 | 0.50 |
| 5/8 | 0.625 |
| 3/4 | 0.75 |
| 7/8 | 0.875 |
Examples
- 6⅛ inches = 6.125
- 6¼ inches = 6.25
- 6⅜ inches = 6.375
- 6½ inches = 6.50
- 6⅝ inches = 6.625
- 6¾ inches = 6.75
- 6⅞ inches = 6.875

If you're tracking measurements over several months, you'll probably use these conversions many times.
PHALLOSAN Tracking App
The tracking app becomes much more useful when every measurement is entered consistently.
Using the correct decimal values helps ensure that your progress history remains accurate and easy to interpret.
Don't forget to include your original conversion image below this section—it provides a quick visual reference for readers.
My Tip:
Measure carefully.
Record the exact number.
Convert it to a decimal.
Enter it immediately.
Following the same routine every time made it much easier for me to compare measurements over the years.
How to Measure Length
If you're measuring before using PHALLOSAN forte or recording progress in the tracking app, a little preparation makes the process much easier.
I recommend following these steps every time.
Step 1
Fit the PHALLOSAN forte correctly.
You don't need to attach the belt while taking the measurement.

Step 2 – Use a Firm, Straight Ruler
A rigid ruler is generally easier to position accurately than a flexible tape measure when measuring length.
Place the ruler along the top (dorsal side) of the penis.
Step 3 – Locate the Pubic Bone
Position the ruler so it begins at the side of the pubic bone rather than the skin surface.
This method helps reduce differences caused by the amount of tissue in front of the pubic bone and makes repeated measurements more consistent.
Press as hard as you can. .
Step 3 – Measure to the Tip
Measure from the pubic bone to the tip of the gland while flaccid ( you will utilize Phallosan Forte bell to pull your penis and measure ).
Take your time and avoid rounding the number up or down.
Recording the exact measurement will make future comparisons more meaningful.
Watch a live demonstration by me in the video below.
Note that I have concealed my identity but you can strictly see my penis measurement as I am a cool 7.1 inches in that video during the measurement.

Why the Bone-Pressed Method Is Often Used
You may notice that different web sites report different average penis sizes.
One reason is that they don't always use the same measuring technique.
The bone-pressed method helps create a more standardized reference point, which is why it's commonly used in research settings.
If your goal is to compare your measurements with published scientific averages, using the same measurement method improves consistency.
My Personal Routine
Every measurement recorded in my long-term progress journal was taken using the same general method and under similar conditions whenever possible.
Keeping the process consistent made it much easier to compare measurements over months and years.
How to Measure Penis Girth Correctly
While most people focus on length, girth is equally important if you're tracking your overall progress.
Fortunately, measuring girth is simple—as long as you use the same method every time.
No Phallosan forte device is needed for this step.
Just measure our girth in the flaccid state and in the erect state and note that in the Phallosan Forte App.
Step 1 – Use a Flexible Measuring Tape
A soft tailor's measuring tape works best because it wraps comfortably around the shaft without bending or lifting away from the skin.
If you don't have one, you can wrap a piece of string around the shaft, mark the point where it overlaps, and then measure the string with a ruler.
Step 2 – Measure at the Same Location
Choose one location on the shaft and use that same location every time you measure.
Many people choose either the midpoint or the thickest part of the erect shaft.
Whichever method you choose, consistency is far more important than the exact location.
Step 3 – Don't Pull Too Tight
The tape should rest gently against the skin without compressing the tissue.
Pulling too tightly can artificially reduce the measurement, while leaving the tape too loose may increase it.
The goal is to record the measurement—not change it.
My Recommendation
Take two or three measurements.
If they're all very close, record the average.
This simple habit helps eliminate small measuring errors.
Record Everything Immediately
One habit that helped me throughout my journey was recording measurements immediately after taking them.
Trying to remember them later almost always leads to mistakes.
Whether you're using the PHALLOSAN Tracking App or your own notebook, record the exact measurement as soon as you finish.
10 Common Measurement Mistakes That Can Give You the Wrong Number
Accurate measurements aren't about getting the biggest number—they're about getting the same measurement method every time.
Even small changes in technique can make your measurements appear larger or smaller than they really are.
Here are the most common mistakes to avoid.
1. Do NOT Measuring While Erect
This is probably the most common mistake.
We focus on measurement while you are flaccid and wear Phallosan Forte Bell. See the video above for measurement demonstration.
If you're comparing measurements over time, always measure under same conditions and when flaccid.
Even small differences in erection quality can affect both length and girth measurements.
To get a full strong erection before the measurement is very difficult, you only get that full erection while you either masturbate or right after sex, and you have to be quick because very quickly the blood receds from the penis and starts making them flaccid. That is why we use the flaccid stretching method above for length measurement.
2. Changing Your Measuring Method
One month measuring from the skin...
The next month measuring from the pubic bone...
Those measurements cannot be fairly compared.
Choose one method and stick with it.
3. Measuring at Different Times of the Day
Many people don't realize that measurements can vary slightly depending on factors such as temperature, recent activity, hydration, and natural day-to-day variation.
If possible, measure around the same time of day each time you record your progress.
4. Pulling the Measuring Tape Too Tight
When measuring girth, the tape should rest gently against the skin.
Compressing the tissue can make the measurement appear smaller than it actually is.
5. Using Different Measuring Tools
Switching between rulers, tape measures, printable charts, or different app's can introduce unnecessary variation.
Using the same tools each time helps keep your measurements consistent.
6. Measuring Too Frequently
One of the biggest mistakes I made early on was measuring too often.
When you're checking every few days, it's easy to become discouraged by normal fluctuations.
I eventually found that measuring at regular intervals—such as once a month—gave me a much clearer picture of long-term progress.
My Personal Routine
I recommend choosing one consistent day each month to take your measurements and record them.
That keeps your data organized and makes long-term comparisons much more meaningful.
7. Rounding Your Measurements
If your measurement is 6.38 inches, record 6.38 inches.
Avoid rounding up or down just to make the number look cleaner.
Small inaccuracies can add up over months or years of tracking.
8. Forgetting to Record Your Results
It sounds simple, but it's surprisingly common.
Write down your measurements immediately after taking them or enter them into the PHALLOSAN Tracking App while they're fresh.
9. Comparing Yourself to Random Internet Claims
Online forums and social media often contain measurements that can't be verified and may not use standardized measuring methods.
If you're going to compare your measurements with published averages, make sure you're using the same measurement technique.
10. Chasing Bigger Numbers Instead of Better Data
This is probably the most important lesson I learned.
Good tracking isn't about trying to create a larger measurement.
It's about collecting accurate information using the same method every single time.
Reliable measurements make it much easier to understand your progress over months and years.
The Golden Rule
The best measurement isn't necessarily the biggest one.
It's the one you can repeat consistently every time.
Consistency creates reliable data—and reliable data tells the real story.
Putting It All Together
Now that you know how to measure correctly and what mistakes to avoid, you're ready to start building a reliable record of your measurements.
In the next section, I'll explain the simple routine I followed throughout my own journey and why consistency mattered far more than checking for changes every few days.
My Personal Measurement Routine
Over the years, one lesson became clearer than anything else:
Consistency beats curiosity.
When I first started using PHALLOSAN forte in 2024, I was excited to see progress and found myself measuring more often than I should have.
It didn't take long to realize that measuring too frequently created more frustration than useful information.
Small day-to-day differences are normal, and they don't necessarily reflect long-term changes.
The Routine That Worked Best for Me
After some trial and error, I settled into a simple routine that I followed throughout my journey.
- ✔ I used the same ruler and measuring tape every time.
- ✔ I measured using the same technique and under similar conditions.
- ✔ I recorded both length and girth immediately after measuring.
- ✔ I converted fractions to decimals before entering them into the PHALLOSAN Tracking App.
- ✔ I focused on long-term trends rather than daily fluctuations.
This routine gave me a much clearer picture of my progress over time.
Why I Didn't Measure Every Week
One of the biggest mind set changes I made was learning to be patient.
Checking measurements too often can lead to unnecessary disappointment because natural day-to-day variation is completely normal.
Instead, I found it more helpful to compare measurements taken weeks or months apart using the exact same method.
My Advice
Pick one day each month and make it your "measurement day."
Use the same measuring method, record the results immediately, and then get back to your normal routine.
Progress is much easier to appreciate when you're looking at consistent long-term data rather than short-term fluctuations.
My Progress Timeline
To keep myself accountable, I documented my measurements and observations over the years.
I didn't create the timeline to prove anything—it simply became a personal record of my journey.
If you're curious about how my routine translated into long-term tracking, you can explore my progress journal below.
Focus on the Trend, Not a Single Number
Whether you're measuring out of curiosity or tracking your progress with PHALLOSAN forte, remember that one measurement doesn't tell the whole story.
Reliable data comes from using the same technique consistently over time.
That's the approach I've followed throughout my journey, and it's the one I recommend to anyone starting their own.
Frequently Asked Questions
Should I measure bone-pressed or non-bone-pressed?
If you want your measurements to be comparable with many published scientific studies, the bone-pressed method is commonly used. Whatever method you choose, use it consistently every time.
How often should I measure?
I generally recommend measuring at regular intervals, such as once a month, rather than every few days. Consistency is more valuable than frequency.
Does the time of day matter?
Measurements can vary slightly due to normal day-to-day factors. Measuring under similar conditions each time helps produce more consistent results.
Why do I need to convert fractions to decimals?
If you're using the PHALLOSAN Tracking App, decimal values make it easier to record and compare measurements over time.
Should I compare my measurements with people online?
Be careful when comparing measurements from forums or social media. Many people use different measuring methods, making direct comparisons unreliable.
