There is no fixed number of hours of sleep prescribed in Jain scriptures for lay (householder) practitioners. Jain teachings emphasize balance, self-control, and clarity of mind, and sleep should support wise living and spiritual practice rather than dominate life.

Practical guidance often suggested:

• Aim for a healthy, restful amount of sleep that matches your age and health (commonly around 6–8 hours for adults, but individual needs vary).
• Avoid excessive sleep that leads to lethargy, and avoid too little sleep that dulls mindfulness.
• Use sleep as a means to maintain energy for ethical living, daily meditation/prayers, and non-violent conduct.
• In daily routine, many Jains try to wake early for morning duties (puja, meditation, study), which supports discipline and mindfulness.

If you want a tradition-based viewpoint, the emphasis is on moderation and mental clarity over rigid hours. If you’d like, I can look for a specific Jain teaching or text on this topic.
