Bhakti Siddhanta Saraswati (Guru of Srila Prabhupad) recommended:
1) 64 rounds a day for pujaris and those living in Holy places. They can fill their time by chanting the Holy names with intense service attitude.
2) 32 rounds a day for retired vanaprasthas. Remaining time can be used by taking care of their old bodies or by serving the need of society by guiding the younger generation.
3) 16 rounds a day for Grahasthas who have many responsibilities for family maintenance (cooking, feeding, serving family deity etc.) and 16 rounds for Brahmacaris who have many services in the temple.
In this way everyone is given maximum opportunity to develop their original service spirit towards the Supreme Lord even while living in the practical world.
