Quick Scoop

Basic size facts

• Area: about 20,700–21,200 km² (around 8,000–8,200 sq mi).

• That’s roughly:
  • About 8–9% of the total land area of the UK.

* Comparable to the US state of New Jersey or slightly larger than Massachusetts.

Shape and distances

• North to south, Wales is about 270 km (around 170 miles) long.

• It is at least about 95–100 km (around 60 miles) wide east to west at its narrowest.

• The coastline, including major offshore islands like Anglesey, is about 2,700 km (1,680 miles) long.

Context: “size of Wales” as a unit

• Because it’s a handy, medium-sized country, “the size of Wales” is often used in news reports to describe the area of storms, icebergs, or forests.
