Roast pork is a forgiving and flavourful centrepiece, but the cut you choose changes the weight you need more than with most meats. A bone-in shoulder, a lean loin, a fatty belly, and a leg all lose different amounts to bone, fat, and cooking, and they suit different kinds of meals. This calculator adjusts for the cut and your guests appetite, and it reminds you about crackling, which for many people is the whole point of roast pork.

Bone-in shoulder needs about 450 grams per person for a standard appetite, 350 grams for light eaters, and 600 grams for hearty eaters. Shoulder is rich in connective tissue and fat, which means it benefits from slow roasting until it is meltingly tender, and it is the best cut if you plan to pull the meat for sandwiches. The bone adds flavour and weight, so the raw number looks generous, but the cooked meat goes further than the raw figure suggests.

Boneless loin is the lean, neat option, needing about 300 grams per person standard, 250 grams light, and 400 grams hearty. It roasts faster, carves into tidy slices, and suits a formal meal with several sides. Its leanness is also its weakness: overcook it and it dries out quickly. Cook it to temperature, rest it well, and do not push it past medium, or buy a loin with the fat cap and skin still attached for insurance.

Belly is the richest cut, needing about 400 grams per person standard, 300 grams light, and 550 grams hearty. Much of that weight is fat, which renders during a long roast and leaves intensely flavoured meat under crisp skin. Belly suits slow roasting and small, rich portions, and it pairs well with sharp accompaniments like apple sauce or pickled vegetables that cut through the fat. Plan smaller portions than you would for loin.

Bone-in leg is the classic large roast for a crowd, needing about 450 grams per person standard, 350 grams light, and 600 grams hearty. It gives a good balance of lean meat and fat, carves well, and produces excellent crackling when the skin is prepared properly. Leg is a good middle ground when you want a traditional roast that is neither as fatty as belly nor as lean as loin.

Crackling deserves its own planning, because great crackling is made before the joint ever reaches the oven. The skin must be dry, scored deeply without cutting into the meat, and salted generously. Pat it dry, leave it uncovered in the fridge overnight if you can, and finish the roast at high heat to crisp the skin. If the skin is damp when it goes in, no amount of oven time will fully rescue it.

Cooking times vary by cut and size, but a useful guide is about 25 minutes per 500 grams plus 25 minutes extra, at around 190 degrees for the first part of the roast. Shoulder for pulling needs longer and slower cooking than that guide suggests, often several hours at a lower temperature until the meat yields easily. A thermometer removes the guesswork: pork is safe at 63 degrees with a short rest, though shoulder for pulling should go much higher, past 90 degrees.

Resting matters for pork just as it does for beef. Rest a loin or leg for 20 minutes, loosely tented, before slicing, so the juices settle and the meat stays moist. Rest crackling separately if you can: lift the skin off, crisp it a little longer if needed, and break it into pieces for serving. Soggy crackling served on top of resting meat is a common disappointment, and separating it avoids the problem entirely.

Side dishes change how much pork people eat. A meal with roast potatoes, stuffing, apple sauce, and vegetables lets you lean toward the light end of the range, while a simpler meal with just bread and salad calls for the standard or hearty setting. Children under ten usually eat about half an adult portion, so count two children as one adult when you enter your guest number.

Leftovers from roast pork are some of the best in the kitchen. Cold sliced pork makes excellent sandwiches with apple sauce and mustard, pulled shoulder reheats beautifully in a bun with barbecue sauce, and leftover belly can be crisped in a pan for a next-day treat. If you want leftovers on purpose, add about a quarter to the calculator result, and store the meat in the fridge within two hours of cooking.

Budget follows the cut more than the weight. Shoulder is usually the cheapest per kilo and gives the most flavour for the money, while loin costs more but wastes nothing. Belly sits in the middle and feels luxurious for its price. Compare the price per kilo, think about what the meal needs, and buy the joint closest to the calculator result rather than the largest one on the shelf.

To use the calculator, enter your guest count, choose the cut, choose the appetite, and say whether you want crackling. You will get the raw weight to buy and a crackling or resting tip. Dry and salt the skin well, cook to temperature, rest before slicing, and your roast pork will feed the table without leaving you short or drowning in leftovers.
