How Big Is Ireland From North To South?

I presume that you want to know the total area covered by Ireland (which is known in the national language, Irish, as Eire). Ireland, when taken as a whole, includes both Northern Ireland (which is one of the four countries which make up the United Kingdom) and the Republic of Ireland.

Ireland covers a total area of approximately 84, 421 square kilometres. When the area of the country is converted into square miles, Ireland covers a total area of approximately 32, 556 square miles.

The Republic of Ireland makes up almost 83 per cent of the total area of Ireland. It covers a total area of approximately 70, 273 square kilometres. When the area of the country is converted into square miles, it covers a total area of approximately 27, 133 square miles.

From north to south approx 290 miles that is from the most northerly point to the most southerly... Just to correct Aki  the republic is made up of 26 counties and Northern Ireland is made up of 6 counties not 4

67miles
