I thought the Daily Mail was in tabloid format and had been for a long time, but I think the Daily Mail is called "a tabloid" because of its market positioning, rather than its format. At the turn of the century, the high-circulation, sensationalist daily newspapers were all tabloids, and the more sober of the major daily newspapers were all in the larger broadsheet format. At least, in England they were; I don't know about the other nations of the United Kingdom. The Guardian (via the Berliner format) and the Times have since gone tabloid (and the Independent went from broadsheet to tabloid before going digital-only), but the Telegraph and the Financial Times are still broadsheets. People still include the Guardian, Times and Independent among "the broadsheets". Wikipedia suggests the Daily Mail was also once a broadsheet, and became a tabloid in 1971: https://en.wikipedia.org/wiki/Daily_Mail#Overview https://en.wikipedia.org/wiki/Daily_Mail#Overview
