Is Lake Superior bigger than Wales? It is an unusual comparison because the two are completely different geographic features. Lake Superior is a freshwater lake in North America, while Wales is a country in western Great Britain. Putting them side by side, however, provides an interesting way to understand the enormous geographic scale of Lake Superior.
Lake Superior forms part of the Great Lakes system along the Canada–United States border, while Wales occupies the western part of Great Britain and shares its eastern border with England. Wales is known for its mountains, valleys, rivers, lakes, coastal landscapes, and historic towns and cities, giving it a very different physical character from the broad expanse of Lake Superior.
The question of size is therefore more interesting than it may first appear. Looking at the two geographic features side by side allows their overall scale to be compared using consistent measurements rather than relying on how large they appear on a map. So, is Lake Superior actually bigger than Wales, and if so, by how much?

How Big Is Lake Superior Compared to Wales?
Lake Superior covers about 31,700 square miles (82,100 square kilometers), while Wales covers approximately 8,023 square miles (20,779 square kilometers). This makes Lake Superior nearly four times larger than Wales in terms of total area.
The difference is about 23,677 square miles (61,323 square kilometers). Put another way, Wales is only about one-quarter the size of Lake Superior, leaving a difference of more than 23,000 square miles between the two.
This is a striking contrast because Wales is an entire country with mountains, valleys, farmland, forests, settlements, and coastal areas. Lake Superior, by comparison, is a single freshwater body whose surface covers an area far greater than the land area of Wales.
By total area, therefore, Lake Superior is clearly larger than Wales, and the difference is substantial rather than marginal.
Lake Superior vs. Wales: Length and Width
Lake Superior extends about 350 miles (563 kilometers) from east to west and reaches roughly 160 miles (258 kilometers) at its maximum width. Its broad dimensions give it a much greater geographic span than its appearance as a single lake might suggest.
Wales measures approximately 170 miles (274 kilometers) from north to south and about 60 miles (96 kilometers) at its widest point from east to west. Its more compact dimensions reflect the shape of the Welsh landmass.
Lake Superior is therefore about twice as long as Wales and more than twice as wide at their respective maximum dimensions. The difference is substantial in both directions, showing that Lake Superior is not larger only because of its total surface area.
The comparison is particularly clear across their widest points. Lake Superior reaches about 160 miles across, compared with roughly 60 miles for Wales, giving the lake more than twice the maximum width of the country.
Lake Superior vs. Wales: Shoreline and Coastline
Lake Superior has about 2,726 miles (4,385 kilometers) of shoreline around its basin. Its shoreline includes bays, inlets, islands, and sections along both Canada and the United States, creating an extensive boundary around the freshwater lake.
Wales has a coastline of approximately 1,680 miles (2,700 kilometers). Its coast contains numerous bays, headlands, beaches, cliffs, and other irregular features along the surrounding seas.
Lake Superior therefore has roughly 1,046 miles (1,685 kilometers) more shoreline than Wales. This is notable because the lake’s shoreline is around 1.6 times the commonly cited length of the Welsh coastline.
The difference also shows why shoreline length does not necessarily correspond directly with overall area. The shape and complexity of a coastline or shoreline can add considerable distance through bays, inlets, islands, and other irregular features.
Which Is Bigger: Lake Superior or Wales?
Lake Superior is significantly bigger than Wales. Its surface area is nearly four times that of Wales, making the difference substantial rather than marginal.
The comparison is also clear from their physical dimensions. Lake Superior is about twice as long as Wales and more than twice as wide at their respective maximum dimensions, giving it a much greater geographic span than Wales.
The shoreline comparison adds an interesting contrast. Lake Superior has about 2,726 miles of shoreline, compared with approximately 1,680 miles of coastline for Wales, so the lake also has a considerably longer boundary.
So, Lake Superior is much bigger than Wales. By surface area, the lake is nearly four times the size of the country, while its greater length, width, and shoreline further demonstrate the difference in geographic scale.
