What size photo do you need for an Iranian passport?

Iranian passports require photos that are 3 centimeters by 4 centimeters. These photos should be taken within six months of the passport application. Each passport photo should show the front view of the person's full face on a plain white background.

Applicants should not wear glasses, scarves around their necks or hats in their passport photos. Female applicants should wear head scarves to comply with regulations set by the Islamic Republic of Iran. The country issues biometric passports that include 40 pages and have the coat of arms on the front cover. Iranian citizens can apply for these passports, which expire after five years.
