Because a whole chicken is partly bone, you need to buy more raw weight than the meat you’ll actually eat. A good rule is about 375g of whole raw chicken per adult, so a standard 1.5kg chicken feeds around four people — with a little left for sandwiches or a second meal.

Sizing the bird

  • Light: ~300g each → a 1.2kg bird for 4
  • Normal: ~375g each → a 1.5kg bird for 4
  • Hungry (or wanting leftovers): ~500g each → a 2kg bird for 4
  • Child: ~200g each

If you love a roast chicken sandwich the next day — and who doesn’t — size up. A bigger bird barely costs more per kilo and gives you a built-in second meal.

How this is worked out

A whole chicken includes bones, so you need more raw weight than you'd think — allow about 375g of whole raw bird per adult. That means a typical 1.5kg chicken comfortably feeds four, with a bit left over for sandwiches.
