Proportional Representation の Constitutional Framingの章。以下引用。"The Constitutional Convention addressed multiple concerns in the process of designing the new Congress. The first was the relationship of the least populous states to the most populous. The battle between big and small states colored most of the Convention and nearly ended hopes of creating a national government. Pennsylvania Delegate Benjamin Franklin summed up the disagreement: “If a proportional representation takes place, the small States contend that their liberties will be in danger. If an equality of votes is to be put in its place, the large States say their money will be in danger. When a broad table is to be made, and the edges of planks do not fit the artist takes a little from both, and makes a good joint.” The “good joint” that emerged from weeks of stalemate was called the “Great Compromise” and created a bicameral legislature with a House, where membership was determined by state population, and a Senate, where each state had two seats regardless of population. The compromise enabled the Convention, teetering on the brink of dissolution, to continue."

Firstly, each proposed constituency has to comply with two numerical limits:
the electorate (number of registered voters) of each constituency must be within 5% of the United Kingdom electoral quota. The electoral quota is the average number of electors per constituency, defined as the total mainland electorate divided by the number of mainland constituencies, where "mainland" excludes four island constituencies: Orkney and Shetland, Na h-Eileanan an Iar (Western Isles), and two on the Isle of Wight.
the area of a constituency must be no more than 13,000 square kilometres."
