Each food type takes different amounts of grill space.
Batch cooking lets you use a smaller grill: the first round feeds early arrivals while the second round finishes. Rolling cooking suits long parties and needs the least grill space.
A 15-20% buffer accounts for awkward item shapes, turning room, and the odd extra guest.
Enter the primary cooking surface of the grill you already own to see if it is large enough.
