How many pounds of crab legs for 10 people?

For a gathering of 10 people, it's generally recommended to serve about 1 to 1.5 pounds of crab legs per person, depending on appetites and what else is being served. This means you would need approximately 10 to 15 pounds of crab legs in total. If crab legs are the main dish, leaning towards the higher end of that range would be ideal.
