Approximately how much of the present day unites states was held by the English in 1763?

By 1763, following the Treaty of Paris, England controlled approximately one-third of present-day United States territory. This included the Thirteen Colonies along the East Coast, stretching from Maine to Georgia, as well as parts of Canada and Florida. The vast lands west of the Appalachians were largely uncolonized and contested by Native American tribes and other European powers. Overall, the English territories included key coastal regions but did not encompass the entirety of the future United States.
