The city covers a hilly area of 15.64 km2 at 151 meters above sea level. The area on which it stands is geologically relatively very young as it was formed about 11,000 years ago (corresponding to the third and last geological period of the Phlegraean area). Marano is located north-west of Naples whose borders are on a slope of the Camaldoli hill. Marano is about 8 km from the Asse Mediano, and about 10 km from the Tangenziale of Naples. The city is just ten kilometers from the international airport of Naples-Capodichino.
