To pass a bill in the U.S. House of Representatives, a simple majority is required for most measures. That means 218 votes if all 435 members are present and voting, since 218 is a majority of 435. If vacancies exist or if not all members are present, the threshold can effectively differ, but 218 is the standard floor requirement for an ordinary bill.

Key points

• Simple majority usually suffices: 218 of 435 voting yes on a standard bill.

• Quorum and voting methods can affect outcome: the House can use voice votes or recorded votes (divisions) to determine passage.

• Constitutional or special rules can alter thresholds: certain actions (e.g., changing constitutional provisions, overriding vetoes) involve different rules, but routine bills follow the simple majority standard.

If you’re asking about a specific bill or a particular chamber (e.g., a state House or another country’s lower house), I can tailor the answer with the relevant threshold. Would you like details for a specific bill or jurisdiction?
