Using information provided by the Watermelon Board, Sheela Prakash at The Kitchn came up with a method to get the right amount of watermelon every time. An average 9kg watermelon will give you about 66 3/4-inch thick wedges, which feeds about 33 people if they each have two wedges each. One pound of watermelon is roughly equal to three wedges, or a serving and a half. For every two pounds of watermelon, you can feed three people. So you need about 300g of watermelon per person. Say, for example, you have 10 people coming to your barbecue or picnic. You'll need a watermelon that weighs around seven pounds. Of course, it's always nice to have a little leftover, so it's best to shoot for a melon that weighs a little more than what you need.
