Italy covers a total area of 301,340 km² (116,348 sq mi), making it the 71st largest country in the world — roughly the same size as the US state of Arizona. Despite ranking outside the global top 70 by land area, Italy packs an extraordinary range of landscapes, from Alpine peaks to Mediterranean islands, into its famous boot-shaped peninsula.
How Big Is Italy in Numbers?
Italy's 301,340 km² accounts for about 0.20% of the Earth's total land area of roughly 148.94 million km². That places it in the middle of the European pack — larger than the United Kingdom (about 244,000 km²) but smaller than France or Spain.
- Total area: 301,340 km² (116,348 sq mi)
- World rank: 71st largest country
- Share of world land: about 0.20%
- Continent: Europe (Southern Europe)
- Capital: Rome
The figure includes Italy's mainland peninsula plus its two large islands, Sicily and Sardinia, and numerous smaller archipelagos. It does not include the two independent micro-states entirely surrounded by Italian territory: Vatican City and San Marino.
The Shape and Span of Italy
Italy stretches roughly 1,200 km from the Alpine north to the southern tip of the peninsula, yet measures only about 550 km at its widest from east to west. This long, narrow geography gives Italy an exceptionally generous coastline of about 7,600 km — the longest of any country bordering the Mediterranean Sea.
The instantly recognizable "boot" silhouette is defined by the Apennine Mountains, which run like a spine down the length of the peninsula, and the towering Alps that arc across the northern border. Tucked between the two mountain systems is the Po Valley, Italy's largest lowland plain and the engine of its agriculture. Italy's highest point sits on the northwestern frontier at Mont Blanc (Monte Bianco), about 4,808 m above sea level, shared with France.
How Italy Compares to Other Countries
Size comparisons make Italy's footprint easier to picture. Within the United States, it closely matches Arizona and is a little smaller than New Mexico. Among its European neighbours, Italy is about 47% the size of France (640,679 km²) and roughly 60% the size of Spain. Looking further afield, Italy is about 80% the size of Japan (377,975 km²), another long, mountainous, peninsula-and-island nation.
What sets Italy apart is not raw size but density of features and population. With around 60 million people on this modest territory, it is one of Europe's more densely populated large nations, and its compactness means a traveller can move from glaciers to citrus groves in a single day.
Islands, Volcanoes and Coastlines
A significant share of Italy's area lies offshore. Sicily, at about 25,700 km², is the largest island in the Mediterranean, while Sardinia is the second largest. Together they add tens of thousands of square kilometres to Italy's total and host distinctive landscapes found nowhere on the mainland.
Italy is also Europe's most volcanically active country. Mount Etna on Sicily is the continent's tallest and most active volcano at roughly 3,357 m, while Mount Vesuvius looms over the Bay of Naples and Stromboli erupts almost continuously off the northern coast of Sicily. The Strait of Messina, separating Sicily from the toe of the boot, narrows to just 3.1 km at its tightest point.
Climate Across Italy's Territory
Because Italy spans so many latitudes and elevations, its climate varies widely across that 301,340 km². The south and the islands enjoy a classic Mediterranean climate of hot, dry summers and mild, wet winters, and they record some of Europe's highest temperatures. The Alpine north is markedly cooler with heavy snowfall, while the Po Valley experiences a continental climate with hot summers and cold, foggy winters.

Frequently Asked Questions
Is Italy bigger than the United Kingdom?
Yes. Italy's 301,340 km² is noticeably larger than the United Kingdom's roughly 244,000 km², though the UK has a larger population.
What US state is Italy closest to in size?
Italy is almost exactly the size of Arizona (about 295,000 km²) and a little smaller than New Mexico, which makes those two states the best American comparisons.
How long is Italy's coastline?
Italy's coastline runs for about 7,600 km, the longest of any Mediterranean country, thanks to its long peninsula plus the islands of Sicily and Sardinia.
Does Italy's area include Sicily and Sardinia?
Yes. The 301,340 km² total includes both Sicily and Sardinia. It does not, however, include the independent enclaves of Vatican City and San Marino.
