How to Measure Your Penis for Surgery or Fillers | Moorgate Andrology

Why Accurate Measurement Is Essential Before Treatment

If you are considering penis enlargement surgery or penis fillers, accurate measurement is essential. Clinical measurements help your urologist:

• Assess suitability for treatment

• Recommend the most appropriate technique

• Set realistic expectations

• Plan treatment safely and proportionately

Inaccurate or inconsistent measurements are one of the most common reasons for misunderstanding expected outcomes.

What You Will Need

• A rigid ruler (preferred)

• A soft measuring tape (for girth only)

• A relaxed, private environment

• Room temperature conditions

Avoid flexible rulers or guessing measurements — precision matters.

How Specialists Measure Penis Length (Medical Standard)

Urologists use a method known as bone-pressed measurement.

Step-by-Step (Flaccid and Erect)

1. Stand upright

2. Place the ruler along the top of the penis

3. Press firmly into the pubic bone

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

5. Do not include foreskin

 This method removes the effect of fat pad thickness and is the only reliable medical standard.

Measuring Erect Length for Surgical Planning

• Achieve a full erection

• Repeat the same bone-pressed technique

• Measure more than once and record the average

This measurement is particularly relevant when discussing:

• Ligament release surgery

• Expected changes in flaccid hang

• Marginal changes in erect length

How to Measure Penis Girth (Circumference)

Girth is especially important when considering penis fillers or fat transfer.

1. Use a soft measuring tape or string

2. Wrap around the thickest part of the shaft

3. Measure snugly, not tightly

4. Record the measurement when erect

Most filler treatments focus on girth enhancement, not length.

Why Measurements Matter for Fillers vs Surgery

Penis Fillers

• Increase girth, not true length

• Can create the appearance of improved flaccid length

• Require adequate baseline anatomy for safe results

Penis Enlargement Surgery

• May involve ligament release, fat transfer, or combined techniques

• Flaccid length increase is usually more noticeable than erect length

• Erect length increase is often marginal and variable

Common Measurement Errors We See in Clinic

• Measuring from the underside

• Not pressing into the pubic bone

• Measuring while seated

• Measuring when partially erect

• Relying on online charts or estimates

These mistakes can lead to unrealistic expectations and poor decision-making.

Should You Measure Yourself or Let a Specialist Do It?

Self-measurement is helpful initially, but clinical measurement during consultation is always recommended before treatment.

Your urologist will:

• Measure accurately

• Assess proportions

• Explain what changes are realistically achievable

• Advise whether surgery or fillers are appropriate
