Coastline of the United Kingdom - wikipedia Coastline of the United Kingdom For the problem in fractal geometry, see How Long Is the Coast of Britain ? Bedruthan Steps, North Cornwall, a spectacular section of the UK coastline, managed by the National Trust The coastline of the United Kingdom is formed by a variety of natural features including islands, bays, headlands and peninsulas. It consists of the coastline of the island of Great Britain and the north - east coast of the island of Ireland, as well as a large number of much smaller islands. Much of the coastline is accessible and quite varied in geography and habitats. Large stretches have been designated areas of natural beauty, notably the Jurassic Coast and the Heritage Coast.

The British Cartographic Society points out that `` The true answer is : it depends ! ''. If the larger islands are added, the coastline as measured by the standard method at Mean High Water Mark rises to about 19,491 miles ( 31,368 km ). According to the CIA Factbook, the length of the UK coastline is around 12,429 km or 7,723 miles, although no details are provided about how this figure was calculated. On the basis of EU Marine Strategy Framework Directive boundaries, the UK coastline can be divided into the eastern, Greater North Sea section, which using 1km2 box counts and including islands is 4,994 km, and a western Celtic Seas coastline, which using the same measurement approach and including Northern Ireland is 14,201 km. Furthermore, the measurement of any coastline is subject to variation depending upon the scale of map used. It is a meaningless statistic without knowing the scale of the map being used and the accuracy of the measurement. A larger map scale and smaller unit of measure will result in more detail being revealed and measured and thus a greater length. And because the resultant length increases exponentially faster than the increase of scale of measurement, there is no such thing as `` an approximate answer '' to this question. This is referred to as the coastline paradox. A coastline is fractal - like -- which means that it has self - similar properties, similar at every scale -- therefore the closer the observer looks, the more detail is revealed, leading to a greater overall length. Shape The United Kingdom 's coastline is more broken than coastlines of many other countries. It has a fractal or Hausdorff dimension or ' wiggliness ' of 1.25, which is comparatively high ; the Australian coastline for example has a fractal dimension of 1.13, and that of South Africa is 1.02. As a result of this shape and the number of islands, the coastline of the UK is longer than that of similar sized countries. For example, the coastline of Italy is around 9,226 km in length, France 7,330 km and Spain 7,268 km. Greece, which has a large number of islands similar to the UK, has a coastline of around 15,147 km. This means the UK has a relatively high coast / area ratio. Nowhere in the UK is more than 113 kilometres ( 70 mi ) from the coast. It is estimated that around 3 million people ( out of 60 million ) live on the coast of the UK. The place furthest from the coast is Coton in the Elms in Derbyshire, which is equidistant from Fosdyke Wash in Lincolnshire ; White Sands between Neston in Cheshire and Flint, Flintshire in Wales ; and Westbury - on - Severn Gloucestershire. Features Islands See also : List of islands of the British Isles, List of islands of the United Kingdom, and British Isles There are over 1,000 islands within the UK ; about 130 are permanently inhabited according to the 2001 Census. Of the remaining islands, some are used for farming and are occupied occasionally, some are nature reserves with restricted access and some are little more than sea - swept rocks. The main occupied islands and island groups in the UK are as follows : Great Britain Ireland ( Northern Ireland is part of the UK ) Anglesey Arran Barra Bute Great Bernera Hoy Islay Jura Lewis and Harris Mull Orkney Shetland Skye The Uists Unst Isle of Wight Yell The Channel Islands ( including Jersey, Guernsey, Alderney and Sark ) and the Isle of Man are not part of the UK ; they are self - governing Crown dependencies therefore their coastlines are not coastlines of the United Kingdom. Peninsulas Peninsulas around the UK coast include : Ards Peninsula Dengie Peninsula Furness Fife The Black Isle Easter Ross Gower Peninsula Kintyre Llŷn Peninsula Penwith Pembrokeshire Rhins of Galloway The Wirral Bays Bays, sea lochs ( loughs ) and large estuaries include : Loch Fyne Loch Long Loch Linnhe Loch Torridon, Carron, Etive, Creran, Eriboll, Seaforth and about a hundred others Belfast Lough Bristol Channel Blackwater Estuary Cardigan Bay Dee Estuary Firth of Clyde Firth of Forth Firth of Tay Humber Estuary Lough Foyle Luce Bay Lyme Bay Mersey Estuary Moray Firth Morecambe Bay Solway Firth Strangford Lough Swansea Bay Thames Estuary The Solent River Tamar The Wash See also Coastline of the North Sea Geography of Great Britain Geography of England § Coastline Geography of Scotland § Coastline Geography of Wales § Coastline Geography of Ireland § Coastline Land 's End to John o ' Groats List of headlands of the United Kingdom List of places on the British coastline List of places on the Jurassic Coast List of spits of the United Kingdom References Jump up ^ `` Geography and Maps ''.
