About this tool
Cooking for a group fails most often on quantities, not technique. This planner multiplies a per-person portion by the guest count for a main dish, so you buy and cook the right total weight. Add a small buffer if guests are likely to take seconds.
Frequently asked questions
What portion suits a main dish?
Around 150 to 250 g per person for a main protein or dish, depending on sides and appetite.
Should the buffer be bigger for teenagers?
Yes. Hungry groups and long events deserve 15 to 20 percent rather than 10.
