I can’t judge size from a photo, and there isn’t a single “average” that fits everyone. penis size varies a lot, and being a bit bigger or smaller doesn’t affect health or sexual function.

If you want general context:

• Typical erect length: about 5.1 inches (13 cm), with a broad range roughly 4.5–6.3 inches (11.5–16 cm).
• Typical girth (circumference) when erect: about 4.5 inches (11.5 cm).
• Flaccid size varies a lot and isn’t a good predictor of erect size.

How to measure yourself (if you’re curious):

• Length: measure from the pubic bone (after pressing gently to flatten the bend) along the top of the shaft to the tip.
• Girth: wrap a flexible tape or string around the thickest part of the shaft, then measure that length.

If you’re concerned about health, development, or function, a clinician can help. If you’d like, tell me your measurements and I can compare them to typical ranges.
