Tuesday Tip: Portion Sizes — How Much Food to Buy for a Crowd
This Tuesday tip: portion sizes is the one I wish someone had handed me years ago — because if you have ever stood in your kitchen making a meal for a crowd and thought “how much of this do I even need?”, you are not alone, and you do not have to guess anymore. After years of feeding my family of seven plus whatever crowd shows up at my table, I have a handful of per-person numbers I plan around every single time, and once you know them, the guesswork is gone.

The panic almost always comes from the same place — not knowing the numbers. Once you have a few reliable per-person amounts in your back pocket, you can walk into the grocery store, multiply by how many people you are feeding, and walk out with exactly what you need. No overbuying, no coming up short, no last-minute trip back. These are the serving sizes I plan around, and they have never let me down.
Tuesday tip: portion sizes — The Numbers I Plan Around
Rice or grains — ¼ cup dry per person. That quarter cup of dry rice or grains cooks up to about ¾ cup, which is one good serving. So if I am feeding twelve people, I start with three cups of dry rice and I know everybody gets a real helping.
Pasta — 2 ounces per person. This is the one that makes shopping easy: a standard 16-ounce box of pasta feeds about eight people. Feeding sixteen? Grab two boxes. It is the simplest math on this whole list.
Potatoes — one medium potato, or about ½ pound, per person. Whether you are baking, mashing, or roasting them, plan on one medium potato each. For sixteen people that is about eight pounds, which is roughly one standard bag.
Rolls — one to two per person. One per person is the floor; two is the safe bet if bread disappears at your table the way it does at mine. I almost always plan for two.
Vegetables and salad — 1 cup of veggies, or 1½ cups of salad, per person. Cooked vegetables settle to about a cup per serving, and leafy salad needs a little more room, so I bump it up to a cup and a half. That keeps the side of the plate as full as the main.
If you want to go deeper, the Old Farmer’s Almanac keeps a handy party-planning chart that lines up closely with how I shop. But honestly, the five numbers above will carry you through almost any gathering you throw.
Now — if you are anything like me and your eyes glaze over the second math walks into the room, I have something for you. My husband Jason sat down and did all of it for us. He built a printable that takes every one of these numbers and scales it across the crowd sizes you actually cook for, so there is nothing left to figure out.

How much food do I need per person for a crowd?
A good rule of thumb is about one to one and a quarter pounds of total food per adult — that is everything on the plate combined, not a pound of meat each. From there I break it down by item: a serving of rice is ¼ cup dry, pasta is 2 ounces, and one medium potato per person. Start with the per-item numbers and you will land right in that range.
How much rice or pasta should I make per person?
For rice, plan ¼ cup dry per person, which cooks up to about ¾ cup — a proper serving. For pasta, it is 2 ounces per person, so one 16-ounce box feeds about eight people. Those two numbers alone cover most of the meals I make for a crowd.
How many potatoes should I buy for a big group?
Plan on one medium potato, or about half a pound, per person — whether you are mashing, roasting, or baking them. For sixteen people that works out to roughly eight pounds, which is about one standard bag. Buy the bag, and you are covered.
Does this Tuesday tip on portion sizes work for a buffet or potluck?
It does. The per-person numbers in this Tuesday tip on portion sizes are the same whether you are plating dinner or setting out a buffet — though for a buffet I nudge the sides up a little, since people serve themselves and tend to take more. When in doubt, round up; leftovers are never a tragedy at my house.
How do I know how much meat to buy for a crowd?
Meat is where most people overspend or come up short, so I lean on a simple guide: figure roughly 6 to 8 ounces of cooked meat per adult, and adjust for whether it is boneless or bone-in. My free printable does this part for you — it spells out exactly how much to buy at each crowd size, boneless versus bone-in, and how to count the kids. Grab it from this week’s newsletter.
