Party planning.... if i would like 100 guests to attend a party, how many people must i invite on average?

is there a ratio formula for figuring out the number of guest who will actually show up at a party they were invited to?

well there isn't a certain ratio to go by;;but if you want 100 people to show up, you should at least invite 200..i would say that would be a good number..


hope you have a great party =]
Reply:never was good at math dunno about a ratio but i would say if you want 100 ppl to show up and knowing that everyone might not show if you just invited 100 i'd say invite 1 to 2 extra ppl for every person you invite, but have enough food for those extra ppl in case everyone you invite shows up
