What you’re looking for is “the congressional apportionment amendment”, and it was passed by congress with the bill of rights, and ratified by many states but every time they almost met the 3/4ths threshold a new state was admitted, and it always remained short. 11 states have ratified it. It had no expiry and as such is still waiting to be ratified by the states. It needs 27 more ratifications to become an amendment to the constitution.
