For most situations, plan on ½ pound (8 oz) of raw pork shoulder per adult. This usually yields about ⅓ pound (5–6 oz) of cooked pulled pork per person after shrinkage.

Quick Scoop

  • Standard rule of thumb:
    • ½ lb raw pork shoulder per adult = ~⅓ lb cooked meat.
  • Light eaters / lots of sides:
    • ⅓ lb (about 5 oz) raw per person (aiming for ~4 oz cooked).
  • Hearty eaters / few sides or big BBQ fans:
    • ¾ lb raw per person (aiming for ~½ lb cooked).
  • Kids under 10:
    • About half an adult portion (¼ lb raw per child).

Pork shoulder loses a lot of weight as fat renders and moisture cooks off—often 40–50% shrinkage , especially with bone-in cuts. That’s why the raw amount per person looks higher than the cooked serving size.

Simple Serving Guide (HTML table)

Below is a handy sizing guide using the common “average appetite” estimate (⅓ lb cooked, about ½ lb raw per adult).

Guests (adults) Raw pork shoulder to buy Approx. cooked meat yield
4 2 lb ~1.3 lb cooked
6 3 lb ~2 lb cooked
8 4 lb ~2.6 lb cooked
10 5 lb ~3.3 lb cooked
15 7.5 lb ~5 lb cooked
20 10 lb ~6.6 lb cooked
These numbers line up with common catering charts for pork shoulder roasts.

When to Adjust Up or Down

  • Serve less per person (closer to ¼ lb cooked):
    • Lots of sides (mac and cheese, beans, slaw, cornbread, etc.).
    • Pulled pork is part of a larger buffet with multiple proteins.
  • Serve more per person (½ lb cooked or more):
    • Pork is the star and there aren’t many heavy sides.
    • Big eaters (teens, sports team, long outdoor day).
  • Sliders vs big sandwiches:
    • Sliders: ~2–3 oz meat per slider; most people eat 2–3, so total still ~5–6 oz cooked per person.
* Full sandwiches: ~4–5 oz cooked meat per sandwich, usually one per person.

Quick example

If you’re cooking for 12 adults with normal appetites and a few sides:

  • 12 × ½ lb raw = 6 lb raw pork shoulder.
  • After shrinkage, you’ll get ~4 lb cooked, which is about ⅓ lb each.
