If you allow 6 ounces raw weight per person (3 thick sausages) then you will need 22lbs 8 ounces allow a little extra for spoilage and tasting so about 24lbs of sausage would do for 60 people. (note these are typical portions in the UK other countries may prefer larger or smaller portions)
A sixteen pound ham may feed 18-20 people
A general rule of thumb is that a boneless ham will provide around 0.25 pounds of meat per person. Therefore, a 6-pound boneless ham would feed approximately 24 people.
That will feed approximately 120 people.
They say to allow about 1/2 pound of meat per person. A 6 pound ham should feed 12 people and an 8 pound ham should feed about 16 people.
To feed 9 people, you typically need about 1/2 to 3/4 pound of spiral ham per person, depending on appetites and whether there are other main dishes. This means you would need approximately 4.5 to 6.75 pounds of spiral ham. It's always a good idea to round up a bit to ensure everyone has enough, so aiming for a 6-pound ham would be a safe choice.
As many as they have the time to.
A half ham typically weighs between 5 to 10 pounds, depending on the size of the ham. It can generally feed about 8 to 12 people, assuming each person has a serving size of about 4 to 6 ounces. The total number of servings may vary based on the side dishes served and the appetites of the guests. Adjustments may be needed for larger gatherings or if ham is the main dish.
From what I've researched, it seems that you should count on 2 servings per pound, so for 30 people, you will need a 15 pound ham. If you want leftovers though, you should go bigger (that is for bone-in ham).
They say to allow about 1/2 pound of meat per person. A 6 pound ham should feed 12 people and an 8 pound ham should feed about 16 people.
50 pounds, a pound per person
Just throw as much as you want in.
If it is a boneless ham, figure on it feeding 24 to 28 people. If it is a bone-in ham, I guess it might feed 18 to 20, but that depends on how big the bone actually is.
