Madagascar is 2.42 times larger than the entire United Kingdom. Areas below are total areas from national statistics; the Mercator factor shows how much a standard web map inflates each one.
Madagascar is larger by 133,030 sq mi (344,546 km²).

On standard maps, the UK and Madagascar look comparable in size. In truth, Madagascar is nearly two and a half times larger than the UK.
Mercator projection formulas stretch surface area proportionally to sec²(φ) = 1 / cos²(φ), magnifying landmasses drastically near the north and south poles.
Madagascar is the world's fourth-largest island, covering 226,658 square miles (587,041 km²). It is 2.42 times larger than the United Kingdom (93,628 square miles).
Over 90% of Madagascar's wildlife is endemic and found nowhere else on Earth.
The UK is the largest island nation in Europe.
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! Madagascar is 2.42 times the size of the United Kingdom.
United Kingdom has about 67,700,000 people versus 29,000,000 in Madagascar, roughly 2.3 times as many. Per square mile, that is about 128 people in Madagascar and 723 in United Kingdom.
By area, United Kingdom (242,495 km²) fits into Madagascar (587,041 km²) about 2.42 times. Shapes differ, so this is an area ratio, not a literal tiling.
