There are 535 voting members in the U.S. Congress: 435 in the House of Representatives and 100 in the Senate.

Quick breakdown

  • House of Representatives : 435 voting members, fixed by federal law since the early 20th century.
  • Senate : 100 members, with 2 senators from each of the 50 states.

So if you’re asking “how many representatives are there in Congress,” in the everyday sense people often mean the 435 House members , but if you include both chambers of Congress, there are 535 voting members total.

Note: At any given moment there can be a few vacancies (unfilled seats), so the number of people currently serving may be slightly below these totals, even though the official size of each chamber remains the same.

TL;DR:

  • House: 435
  • Senate: 100
  • Congress total: 535 voting members (with occasional vacancies in practice).
