How many slabs of ribs for 6 people?

For 6 people, it's generally recommended to plan for about half a slab of ribs per person, as ribs can be quite filling. This means you would need around 3 slabs of ribs to adequately serve everyone, assuming each slab has around 10-13 ribs. Adjustments can be made based on the appetites of your guests and any additional sides being served.
