How the calculation works
What span of control tells you
Span of control is the number of people reporting directly to a manager. Your average span is a starting point for reviewing management capacity, reporting layers, and costs. The calculation assumes everyone except the person in the top role reports to someone in the organization. That includes managers who report to other managers. To calculate average span, subtract one from total employees and divide by the number of managers with direct reports.

How team size changes the structure
For a 100-person organization, the model estimates about 20 managers and 3 management layers at a span of 5. At a span of 10, it estimates about 10 managers and 2 layers. Gallup reported an average of 10.9 direct reports in 2024 and 12.1 in 2025. Compare those figures with the work your managers and teams handle.
Where smaller teams make sense
Smaller teams often fit complex work, decisions with significant consequences, or managers with substantial individual responsibilities. Examples include specialized engineering, executive leadership, and compliance. Published reference ranges suggest 3 to 5 direct reports for managers with significant individual work and 5 to 8 for knowledge work such as engineering or product development.
Where larger teams make sense
Larger teams can work well with consistent processes and clear performance measures. Back-office operations, support teams, and call centers may have 12 to 20 direct reports per supervisor, allowing managers to focus on coaching, problem-solving, and improvement.
