How to measure your penis correctly

Why Accurate Measurement Matters

Accurately measuring your penis is essential when:

• Comparing yourself to average ranges

• Assessing suitability for penis enlargement treatments

• Tracking changes after surgery, fillers, or fat transfer

• Discussing concerns clearly with a specialist

Incorrect measurement is extremely common and often leads to unnecessary anxiety or unrealistic expectations.

What You’ll Need

• A rigid ruler or measuring tape

• A private, relaxed environment

• Room temperature (cold affects flaccid size)

Avoid soft tape measures for length, as they bend and give false readings.

How to Measure Penis Length (Flaccid)

1. Stand upright

2. Place the ruler on the top side of the penis

3. Press firmly into the pubic bone (this is essential)

4. Measure from the pubic bone to the tip of the glans

5. Do not include foreskin

Pressing into the pubic bone ensures fat pad thickness does not distort the measurement.

How to Measure Penis Length (Erect)

1. Achieve a full erection

2. Stand upright

3. Place the ruler along the top of the penis

4. Press into the pubic bone

5. Measure to the tip of the glans

This is the standard medical method used by urologists worldwide.

How to Measure Penis Girth (Circumference)

1. Use a soft measuring tape or string

2. Wrap it around the thickest part of the shaft

3. Do not pull tight — snug only

4. Measure in the middle of the shaft for consistency

Record girth when erect if considering girth enhancement treatments.

Common Measurement Mistakes

• Measuring from the underside

• Not pressing into the pubic bone

• Measuring while seated

• Using flexible rulers for length

• Measuring when partially erect

These errors often lead to underestimating true length.

What Is Considered Average?

Average erect penis length:

• Approximately 5–5.5 inches (12.5–14 cm)

Most men seeking treatment are within the normal range and are motivated by confidence, proportion, or personal preference rather than medical necessity.
