20. Not so much

the number was set at 435 by the Apportionment Act of 1911, which apportioned 433 representatives for the current states of the Union and one additional each for Arizona and New Mexico (which became states in 1912). When Alaska and Hawaii became states each got one representative in addition to the 435 then seated in the House to make the number 437 until reapportionment after the 1960 census returned the total to 435.

435 seems somewhat low for a country of over 300 million people; the UK has at present 646 parliamentary constituencies with a fifth the population, so one member of parliament for, roughly, every hundred thousand people vs one representative for every seven hundred thousand.
