How Many Racks of Ribs for 10 People
Prices checked Oct 2026, average US grocery prices. Portions follow common catering rules of thumb; safe temperatures follow USDA. How we calculate
For a 10-person gathering, plan 5 racks of baby back ribs (about half a rack per guest). With a rib rack holding them upright, all 5 fit on one 22-inch kettle or an 18-inch smoker. Low and slow at 225°F for 5–6 hours gives the best result, and at this size you can afford meatier baby backs over spare ribs.
Baby Back vs St. Louis vs Spare Ribs for 10 People
| Cut | Rack weight | Racks for 10 | Total weight |
|---|---|---|---|
| Baby back (loin back) | ~2 lbs, 11–13 bones | 5 racks | 10 lbs (4.5 kg) |
| St. Louis-cut spare ribs | ~2.75 lbs | 4 racks | 11 lbs (5.0 kg) |
| Whole spare ribs | ~3.5 lbs, feeds about 3 | 3 racks | 10 lbs (4.8 kg) |
"Rack" and "slab" mean the same thing. Baby backs are leaner and cook faster; St. Louis spares have more meat per rack, so you buy fewer of them.

| Drinks cooler | 1 × 48-quart cooler for 25 cans, plus 2 × 10-lb bags of ice |
