Iran at a Glance
Iran: Middle Eastern Powerhouse Larger Than Expected
Iran ranks as the 18th largest country in the world with a territory of 1,648,195 square kilometers (636,372 square miles). Located in Western Asia, Iran is the largest country in the Middle East and one of the largest in Asia, sharing borders with Turkey, Iraq, Afghanistan, Pakistan, Armenia, Azerbaijan, and Turkmenistan, while also having extensive coastlines along the Persian Gulf, Gulf of Oman, and Caspian Sea.
What makes Iran geographically remarkable is its substantial size, which often surprises people unfamiliar with Middle Eastern geography. Iran is larger than Alaska, France, Germany, the United Kingdom, and Italy combined. The country could fit Texas, California, and Montana together within its borders, yet many people underestimate Iran’s true dimensions.
Located between approximately 25° and 40° North latitude, Iran experiences minimal distortion on standard Mercator projection maps. What you see on most world maps is a reasonably accurate representation of Iran’s true size relative to other countries, though its complex topography includes dramatic elevation changes that aren’t immediately apparent.
