I don't have specific Glassdoor data on the average hours per week for sonographers. However, typically, sonographers work full-time, which usually means around 40 hours a week. Some positions may require evening or weekend shifts, depending on the healthcare facility's needs.
If you're exploring a career as a sonographer, it's good to be prepared for varying schedules, especially in hospital settings where patient care is ongoing. If you have more specific questions or need details on another aspect of the role, feel free to ask!
