What tire width should I run on my gravel bike?

For general mixed-surface riding, 38–42mm is the sweet spot — fast enough on road and capable on most gravel. For rougher terrain and bikepacking, go 45–50mm. If you ride mostly paved roads with occasional gravel, 35–38mm works well. Run the widest tire your frame clears for maximum comfort and capability — you can always run lower pressures rather than narrower tires.
