This chapter describes how the concept of geographical scale has been handled in British geography over the last century. With geography meaning, literally, ‘writing about the Earth’, it would seem that the matter of scale should be largely settled: geographers are the ‘global scientists’. In practice this has not been the case and, in fact, the global has been a relatively neglected scale of geographical analysis. Most geographers have spent most of their time ‘writing about their country’ and those from Britain have been no exception. This chapter explores how and why this privileging of the national scale has operated in a century of British geography. It also discusses geographical scale as a social construction, commercial geography and political geography, geography for national and local planning, urban geography, glocalisation and world cities.
