Plan on 6–8 ounces of raw boneless pork loin per adult, or 8–12 ounces raw per adult if bone-in. Cook pork loin to 145°F and let it rest 3 minutes before slicing.
How Much Pork Loin Per Person: plan on 6 ounces cooked pork loin per adult, or about 8 ounces raw boneless pork loin before roasting. If the meal has few sides, many teens, or no starter, move to 10 ounces raw per adult so the platter does not run short.
For kids, plan on 3 to 4 ounces cooked, or 4 to 5 ounces raw. A 4-pound raw boneless loin serves about 8 adults; a 5-pound loin serves about 10. Cook pork loin to 145°F (63°C), then rest it 3 minutes before you slice and serve it. Serve thin slices.
The Short Answer, With Numbers
Plan on 6 to 8 ounces cooked pork loin per adult. Because pork loin loses moisture and fat while roasting, buy 8 to 12 ounces raw boneless pork loin per adult.
For a mixed crowd, the safest planning number is 10 ounces raw boneless pork loin per person. That gives a solid serving without depending on perfect carving or zero shrinkage.
| Relevant pork item | Safe minimum internal temperature | Rest time |
|---|---|---|
| Beef, pork, veal and lamb – steaks, chops, roasts | 145°F (63°C) | 3 minutes |
| Leftovers, reheated | 165°F (74°C) | None |
Buying Amounts for Boneless Pork Loin
| People | Light portions | Standard portions | Big portions |
|---|---|---|---|
| 4 | 2 lb raw | 2.5 lb raw | 3 lb raw |
| 6 | 3 lb raw | 3.75 lb raw | 4.5 lb raw |
| 8 | 4 lb raw | 5 lb raw | 6 lb raw |
| 10 | 5 lb raw | 6.25 lb raw | 7.5 lb raw |
| 12 | 6 lb raw | 7.5 lb raw | 9 lb raw |
Use the light column when pork is one of several mains, or when you have heavy sides. Use the standard column for a normal dinner plate. Use the big column for buffets, leftovers, or meat-focused meals.
A simple formula: guests × 10 ounces raw boneless pork loin. Divide by 16 to get pounds. For 9 guests: 9 × 10 = 90 ounces, or 5.625 pounds. Buy a 5.5 to 6 lb roast.
For cooked portions, estimate 6 ounces cooked per adult for lighter eaters and 8 ounces cooked per adult for generous servings. Kids usually fit closer to 3 to 4 ounces cooked.
Bone-In, Stuffed, and Leftover Planning
For bone-in pork loin, buy more because bone weight does not serve like meat. Plan about 12 to 16 ounces raw per adult, depending on how much bone is attached.
If the pork loin is stuffed, rolled, or heavily trimmed, do not cut the meat estimate too far. Use at least the standard number: 10 ounces raw per adult.
If you want leftovers, add 25% to 50%. For 8 adults at the standard 5 lb raw amount, buy 6.25 to 7.5 lb if sandwiches or second meals are part of the plan.
Do not rely on roast length alone. Two pork loins can look similar but weigh differently. Buy by weight, cook pork loin roasts to 145°F, then rest for 3 minutes before slicing.
For reheated leftover pork loin, heat the leftovers to 165°F. Slice leftovers before reheating if you want them to heat more evenly and avoid drying out the whole piece.
Pork Loin Amount Per Person
Plan on 6 to 8 ounces of raw boneless pork loin per adult. That usually yields about 4 to 5 ounces cooked after trimming and cooking loss.
For a sit-down dinner where pork loin is the main protein, use 8 ounces raw per person. For a buffet, mixed grill, or meal with several hearty sides, use 6 ounces raw per person.
| Guests | Light portions, 6 oz raw each | Standard portions, 8 oz raw each |
|---|---|---|
| 4 people | 1 1/2 lb | 2 lb |
| 6 people | 2 1/4 lb | 3 lb |
| 8 people | 3 lb | 4 lb |
| 10 people | 3 3/4 lb | 5 lb |
| 12 people | 4 1/2 lb | 6 lb |
| 16 people | 6 lb | 8 lb |
Fast Rule for Buying Pork Loin
Use this shortcut: number of guests × 1/2 lb raw boneless pork loin. That gives generous dinner portions for most groups.
Example: for 9 adults, 9 × 1/2 lb = 4 1/2 lb raw pork loin. If you want leftovers, round up to 5 to 5 1/2 lb.
For smaller appetites, calculate 3/8 lb per person. For 8 people, 8 × 3/8 lb = 3 lb raw pork loin.
Bone-In vs Boneless Pork Loin
Boneless pork loin is simple: buy 6 to 8 ounces raw per person. Bone-in pork loin needs more because the bone is not edible.
For bone-in pork loin, plan on 10 to 12 ounces raw per adult. For 8 adults, buy about 5 to 6 lb bone-in pork loin.
If the roast has a thick fat cap, buy toward the higher end. A heavily trimmed boneless loin can stay near the lower end.
Worked Examples
Family dinner for 5: use 5 × 8 oz = 40 oz, or 2 1/2 lb raw boneless pork loin. Buy a 2 1/2 to 3 lb roast.
Holiday meal for 12: use 12 × 8 oz = 96 oz, or 6 lb raw boneless pork loin. If serving ham or turkey too, 4 1/2 to 5 lb is enough.
Buffet for 20: use 20 × 6 oz = 120 oz, or 7 1/2 lb raw boneless pork loin. Two roasts around 3 3/4 lb each cook more evenly than one huge roast.
When to Buy More or Less
Buy more for teenagers, big eaters, sandwiches, or minimal sides. Use 10 ounces raw boneless per person if pork is the only main dish and you want leftovers.
Buy less when serving pasta, potatoes, beans, stuffing, rolls, or another protein. In that case, 5 to 6 ounces raw boneless per person is usually enough.
Cook pork loin to a safe minimum internal temperature of 145°F (63°C), then let it rest for 3 minutes before slicing.
Quick Serving Size Chart
Plan pork loin by cooked edible portion first, then buy extra for cooking loss. A practical target is 6 ounces cooked pork loin per adult for a normal dinner, or 8 ounces for big appetites.
| Guests | Light meal | Standard dinner | Hearty portions |
|---|---|---|---|
| 2 people | 12 oz raw | 1 lb raw | 1 1/4 lb raw |
| 4 people | 1 1/2 lb raw | 2 lb raw | 2 1/2 lb raw |
| 6 people | 2 1/4 lb raw | 3 lb raw | 3 3/4 lb raw |
| 8 people | 3 lb raw | 4 lb raw | 5 lb raw |
| 10 people | 3 3/4 lb raw | 5 lb raw | 6 1/4 lb raw |
| 12 people | 4 1/2 lb raw | 6 lb raw | 7 1/2 lb raw |
Best Rule of Thumb
Use 1/2 pound raw boneless pork loin per adult for a standard meal. That assumes some shrinkage during roasting and gives about 6 ounces cooked pork per person.
For a lighter plate, use 6 ounces raw per person. This works when you have filling sides, bread, appetizers, or several other proteins on the table.
For generous servings, use 10 ounces raw per person. Use this for holiday meals, buffet service, teenagers, or when pork loin is the only main dish.
| Serving style | Raw pork loin per person | Cooked serving target |
|---|---|---|
| Light | 6 oz | 4 to 5 oz |
| Standard | 8 oz | About 6 oz |
| Hearty | 10 oz | 7 to 8 oz |
Worked Examples
For 6 adults at a normal dinner, multiply 6 by 8 ounces. That equals 48 ounces raw, or 3 pounds of boneless pork loin.
For 10 adults with big appetites, multiply 10 by 10 ounces. That equals 100 ounces, or 6 1/4 pounds raw. Buy a 6 to 6 1/2 pound loin.
For 8 adults plus 4 children, count each child as about half an adult serving. That is 10 adult portions total. Buy about 5 pounds raw for a standard meal.
For a buffet with ham, chicken, or another main dish, use the light figure. For 12 guests, 12 by 6 ounces equals 72 ounces, or 4 1/2 pounds raw.
Edge Cases That Change the Number
If the pork loin is bone-in, buy more. Use 3/4 pound raw per adult for a standard serving because the bone adds weight but not edible meat.
If you want leftovers, add 1 extra pound raw for every 4 adults. For 8 adults, a standard 4 pound loin becomes 6 pounds if you want planned leftovers.
If slicing very thin for sandwiches, use 4 ounces cooked pork per sandwich. A 3 pound raw boneless pork loin will usually cover about 8 to 10 sandwiches.
If serving thick carved slices, estimate 2 slices per adult at about 3 ounces cooked each. That lines up with the standard 6 ounce cooked serving.
Cook pork loin to 145°F and let it rest 3 minutes. Check the center with a food thermometer, especially on roasts over 3 pounds.
How To Calculate Total Weight
Use cooked portions first, then convert to raw weight. Pork loin loses moisture and fat while roasting, so the raw roast must be heavier than the meat you plan to serve.
- 1. Pick the serving size. Use 6 ounces cooked pork loin per adult for a normal dinner. Use 8 ounces for big eaters or a meat-focused meal. Use 4 ounces for kids or buffet plates.
- 2. Count your guests by appetite. Do not average everyone blindly. For 6 adults, 2 big eaters, and 3 kids, calculate each group separately so you do not overbuy or run short.
- 3. Multiply guests by cooked ounces. Example: 6 adults × 6 ounces = 36 ounces. 2 big eaters × 8 ounces = 16 ounces. 3 kids × 4 ounces = 12 ounces.
- 4. Add the cooked meat target. In that example, 36 + 16 + 12 = 64 ounces cooked pork loin. Since 16 ounces equals 1 pound, that is 4 pounds cooked meat.
- 5. Convert cooked weight to raw weight. Plan on about 25% shrinkage for boneless pork loin. Divide cooked weight by 0.75. For 4 pounds cooked: 4 ÷ 0.75 = 5.33 pounds raw.
- 6. Round to a buyable roast size. Round up, not down. A 5.33-pound need means buying a 5.5- to 6-pound boneless pork loin roast.
- 7. Add extra only when needed. Add 10% if you want sandwiches, no heavy sides, or second servings. For a 6-pound roast, 10% extra means about 6.6 pounds total.
Quick Formula
Raw pork loin needed = guests × cooked ounces per person ÷ 16 ÷ 0.75.
For 10 adults at 6 ounces cooked each: 10 × 6 = 60 ounces. 60 ÷ 16 = 3.75 pounds cooked. 3.75 ÷ 0.75 = 5 pounds raw pork loin.
For 12 adults at 8 ounces each: 12 × 8 = 96 ounces. 96 ÷ 16 = 6 pounds cooked. 6 ÷ 0.75 = 8 pounds raw pork loin.
For 20 buffet guests at 4 ounces each: 20 × 4 = 80 ounces. 80 ÷ 16 = 5 pounds cooked. 5 ÷ 0.75 = 6.67 pounds raw, so buy about 7 pounds.
Boneless vs. Bone-In
Most pork loin roasts sold for slicing are boneless. If yours is bone-in, add about 1 extra pound for every 4 to 5 pounds of boneless meat you would have bought.
Example: if the formula says 6 pounds boneless, buy about 7 to 7.5 pounds bone-in. The bone adds weight but does not add sliced meat to the platter.
Common Edge Cases
If pork loin is one of two meats, cut the cooked portion to 4 ounces per person. For 12 guests: 12 × 4 ÷ 16 ÷ 0.75 = 4 pounds raw pork loin.
If there are very heavy sides, 5 ounces cooked per adult is usually enough. For 14 adults: 14 × 5 ÷ 16 ÷ 0.75 = 5.83 pounds raw, so buy 6 pounds.
If leftovers are the goal, calculate dinner first, then add the extra. For 10 adults at 6 ounces, the base is 5 pounds raw. Add 25% for leftovers: 6.25 pounds raw.
Cook pork loin, as a pork roast, to 145°F (63°C) and let it rest for 3 minutes before slicing.
Bone In Versus Boneless Amounts
Use 1/2 pound boneless pork loin per adult for a normal dinner portion. Use 3/4 pound bone-in pork loin per adult because the bone and trimming reduce the edible yield.
For lighter eaters, plan 6 ounces boneless or 10 ounces bone-in per person. For big appetites, buffet service, or leftovers, plan 10 ounces boneless or 1 pound bone-in per person.
Quick Planning Amounts
| Guests | Boneless pork loin | Bone-in pork loin |
|---|---|---|
| 2 people | 1 pound | 1 1/2 pounds |
| 4 people | 2 pounds | 3 pounds |
| 6 people | 3 pounds | 4 1/2 pounds |
| 8 people | 4 pounds | 6 pounds |
| 10 people | 5 pounds | 7 1/2 pounds |
| 12 people | 6 pounds | 9 pounds |
The simple conversion is: bone-in pork loin needs about 50% more weight than boneless. A 4-pound boneless roast feeds about 8 adults; a similar bone-in roast should be about 6 pounds.
Boneless pork loin is the cleaner number because nearly all of the purchased weight can be sliced. You still lose some moisture during roasting, but you are not paying for bone.
Bone-in pork loin usually slices into fewer edible ounces because part of the roast is rib bone. It can look generous on the platter, but the served meat per pound is lower.
Worked Examples
For 6 adults at a plated dinner, buy 3 pounds boneless. That gives each person about 8 ounces raw weight before roasting.
For the same 6 adults with bone-in pork loin, buy 4 1/2 pounds. That accounts for the bone while keeping the serving size close to a standard dinner portion.
For 8 adults and 4 children, count the children as 4 half-portions. That equals 10 adult portions. Buy 5 pounds boneless or 7 1/2 pounds bone-in.
For 10 adults with planned leftovers, do not stop at 5 pounds boneless. Buy 6 to 6 1/2 pounds boneless or 9 to 10 pounds bone-in.
For a buffet with several proteins, reduce the pork loin by about 25%. For 12 guests, buy 4 1/2 pounds boneless or about 6 3/4 pounds bone-in.
If pork loin is the only main dish, keep the full amount. If it is served with ham, turkey, or another meat, use the buffet numbers instead.
Edge Cases That Change the Math
- Thin sandwich slices: plan 4 to 5 ounces boneless per person, or 6 to 8 ounces bone-in.
- Holiday meal with many sides: plan 6 ounces boneless or 10 ounces bone-in per adult.
- Teenagers or heavy eaters: plan 10 ounces boneless or 1 pound bone-in per person.
- Leftover roast pork: add 1 extra pound boneless for every 3 to 4 people.
Do not confuse pork loin with pork tenderloin. Tenderloin is smaller and leaner, so it is often portioned by piece count. Pork loin is a roast and is best planned by pounds per person.
Cook pork loin, whether bone-in or boneless, to 145°F and let it rest for 3 minutes. Measure the temperature in the thickest part, away from the bone.
Adjusting For Appetites And Sides
Use 6 ounces cooked pork loin per adult as the standard dinner portion. Because pork loin loses moisture during roasting, plan about 8 ounces raw boneless pork loin per adult to land near that serving size.
For lighter eaters, buffet meals, or lunches, plan 5 ounces cooked per adult. That equals about 6 to 7 ounces raw boneless pork loin per person.
For big eaters, holiday plates, or meals where pork is the main attraction, plan 8 ounces cooked per adult. That usually means 10 to 11 ounces raw boneless pork loin per person.
Quick Portion Guide
| Meal style | Cooked pork per adult | Raw boneless pork loin per adult |
|---|---|---|
| Light meal with many sides | 5 oz | 6 to 7 oz |
| Standard dinner | 6 oz | 8 oz |
| Hearty meal | 8 oz | 10 to 11 oz |
Children usually need less. Count ages 4 to 8 as 3 ounces cooked, or about 4 ounces raw. Count ages 9 to 12 as 4 ounces cooked, or about 5 to 6 ounces raw.
Teenagers often eat adult portions. For a sports team, cookout, or family with hungry teens, use the hearty number: 10 to 11 ounces raw pork loin per teen or adult.
How Sides Change The Number
If you serve 3 or more filling sides, reduce the pork by about 1 ounce cooked per adult. Filling sides include mashed potatoes, mac and cheese, stuffing, rice, rolls, beans, or pasta salad.
If sides are mostly salad, roasted vegetables, fruit, or slaw, do not reduce much. Keep the standard 6 ounces cooked per adult, or move to 8 ounces for big appetites.
For sandwiches, slice thinner and plan 4 ounces cooked pork per sandwich. That is about 5 to 6 ounces raw pork loin per sandwich, before trimming and cooking loss.
For a buffet with several proteins, plan 3 to 4 ounces cooked pork per adult. If pork loin is the only meat, do not use buffet math; use 6 to 8 ounces cooked instead.
Worked Examples
For 6 adults at a normal dinner, use 6 adults × 8 ounces raw. That equals 48 ounces, or 3 pounds of raw boneless pork loin.
For 10 adults with mashed potatoes, rolls, and green beans, use 7 ounces raw each. That equals 70 ounces, or 4.4 pounds. Buy a 4 1/2 to 5 pound roast.
For 8 adults and 4 children ages 4 to 8, use 8 × 8 ounces plus 4 × 4 ounces. That equals 80 ounces, or 5 pounds raw boneless pork loin.
For 12 hearty eaters with light sides, use 11 ounces raw each. That equals 132 ounces, or 8.25 pounds. Buy about 8 1/2 to 9 pounds.
Edge Cases That Need Extra Pork
- Leftover goal: add 4 to 6 ounces raw pork loin per person if you want sandwiches the next day.
- Heavy trimming: add 10% if the roast has a thick fat cap or uneven ends you will remove.
- Very long meal: add 1 to 2 ounces raw per adult for grazing-style dinners.
- Bone-in roast: buy more than boneless, because the bone adds weight without adding servings.
Cook pork loin to 145°F and let it rest 3 minutes. Slice after resting so the roast keeps more juice and the portions look fuller on the plate.
