California is 40.7% larger than Italy (1.41 times the size). Areas below are total areas from national statistics; the Mercator factor shows how much a standard web map inflates each one.
California is larger by 47,348 sq mi (122,630 km²).

Both California and Italy share similar Mediterranean climate zones and elongated shapes, but California spans significantly more total area.
Mercator projection formulas stretch surface area proportionally to sec²(φ) = 1 / cos²(φ), magnifying landmasses drastically near the north and south poles.
California is 41% larger than Italy. California covers 163,696 square miles (423,970 km²) compared to Italy's 116,348 square miles (301,340 km²). Italy has a larger population (58.8M vs 39.5M).
California produces over a third of the country's vegetables and two-thirds of the country's fruits and nuts.
Italy completely encircles two independent sovereign nations: San Marino and Vatican City.
Mercator factors use the center latitude only (area scale = 1 / cos² of latitude), so they are approximations for places that span many degrees of latitude.
Use published areas from national statistics offices or census gazetteers rather than judging by pixels on a flat web map.
Remember that Web Mercator tiles distort areas by 1/cos²(latitude). High-latitude regions appear vastly larger than equatorial states.
Drag one outline over the other in the true size tool; the shape is re-projected as it moves, so it keeps its real size.
Yes, California is 1.41 times the size of Italy, with 47,348 more square miles of territory.
California has 840 miles of mainland Pacific coast, while Italy's boot-shaped peninsula features over 4,700 miles of coastline due to its numerous islands and inlets.
Italy has about 58,850,000 people versus 39,538,223 in California, roughly 1.5 times as many. Per square mile, that is about 242 people in California and 506 in Italy.
By area, Italy (301,340 km²) fits into California (423,970 km²) about 1.41 times. Shapes differ, so this is an area ratio, not a literal tiling.
