Estimating party food for kids and adults when half the guests are kids

Estimating party food for kids and adults is where most hosts overspend, because they count every name on the list as a full plate. A seventh birthday in Plano with 25 adults and 25 children is not a party of 50. It is a party of about 37, and the difference is four dozen tamales you would have paid for and frozen. I have sized enough family parties to know the number, and I have watched enough of them to know what the kids actually eat.

The short answer: Count each child under twelve as half an adult, then order two big tamales per adult portion with sides, or three without. For 25 adults and 25 kids that is 37 or 38 portions, so 75 tamales with rice and beans, which rounds up to seven dozen. Add a snack table of chips, fruit and cut vegetables, and let the children eat first.

The rest of this article is the math behind that answer, what children really eat when a buffet is in front of them, how a snack table quietly cuts the order, and what changes when the kids are toddlers or teenagers.

Party food for kids and adults: the half-guest rule

Here is the rule, and then the reasons. A child between about three and eleven eats roughly half of what an adult eats at a party. Not because they are polite about it, but because they are distracted. There is a bounce house, a cousin, a dog. They take a plate, eat a tamal and four chips, and disappear for an hour.

So when I get a request that says “50 guests, half of them kids,” I do not price 50. I price 25 adults plus 12 or 13 child portions, which is 37 or 38 adult-sized portions. At two tamales per portion with sides, that is 75 tamales. At three per portion for a dinner with no sides, it is about 113. Either way you round up to the next dozen, because leftover tamales reheat and running short does not.

The rule has two exceptions, and both push the number up, not down:

• Teenagers count as adults, and a table of fourteen-year-old boys after a soccer game counts as more. Give them a full portion and a little extra.
• Children under three count as zero for the main food. They eat off a parent’s plate. Count the parent as an adult and move on.

Everything else, the three-to-eleven crowd that fills most birthday parties, is a half.

The math, from headcount to dozens

This table does the arithmetic for the mixes I see most often. It assumes rice, beans and chips on the table, so two tamales per adult portion, and it rounds up to whole dozens at my delivery price of $60 per dozen.

Look at the fourth row for a second. One hundred names on the list, 60 of them children, and the order is twelve dozen, which is what I would send for 70 adults. That is the half-guest rule doing exactly what it is supposed to do. If the same host had ordered for 100 adults, they would have paid for five extra dozen.

If you want to check the adult side of the math, my guide to how many tamales per person goes through lunch versus dinner and the pork-to-chicken split, and the catering page has a headcount calculator that does the rounding for you.

What kids actually eat at a party

I am a mother and a cook, so I will tell you the truth: children eat the food that is easy to hold and does not surprise them. That turns out to describe a tamal very well.

A chicken tamal in green tomatillo salsa is the one most kids go for. The chicken breast is mild, the masa is soft, and if you ask me to send the salsa on the side for part of the order, the tamal itself has no heat at all. Cut it in half on the plate and it is the right size for a seven-year-old. The pork in red salsa has what a reviewer called “a little kick,” which most kids over eight are fine with and most kids under six push to the side.

So for a mixed party I usually suggest:

• Lean the kids’ share toward chicken, salsa on the side, and cut them in half at the table.
• Keep the adults’ share about sixty-forty pork over chicken, salsa on, the way I would for any party.
• Put out rice and beans plain, no jalapeño on top, so there is a safe plate for the pickiest child in the room.

For the truly selective eaters, the ones who will only eat white food, I wrote a whole piece on a catering menu for picky eaters. The short version is that plain rice, a mild tamal and a bowl of fruit cover almost everyone.

The snack table does more work than the buffet

If there is one thing I could get every host to do, it is this: set up a small snack table an hour before the food line opens, and keep it away from the main table. Chips, cut fruit, baby carrots, maybe a bowl of the green salsa for the adults. It costs very little, and it changes the numbers in three ways.

1. It feeds the kids while they are hungriest, which is the moment they arrive. By the time the tamales come out they are half full and happily distracted.
2. It gives the adults something to do while they wait, so nobody hovers over the pans and opens them early.
3. It makes the half-guest rule safe. A child who has eaten a handful of chips and some watermelon is genuinely a half-portion at the buffet, not a hungry one.

I have watched hosts skip the snack table and then panic at the buffet because the children ate first and ate a lot. The snack table is the cheapest insurance in party planning. Fruit in particular does something strange: kids who ignore it at home eat it in handfuls at a party, and every handful is a tamal you do not need.

Timing: kids eat first, adults eat later

At a mixed party, food happens in two waves whether you plan for it or not. The children eat as soon as anything is out. The adults eat when the conversation lets them, usually an hour later. If you open every pan for the first wave, the second wave gets lukewarm tamales and picked-over rice.

So plan the waves. Open one pan of chicken and one of rice when the kids line up. Keep the rest lidded and stacked; tamales in their husks hold heat well past an hour that way. When the adults drift over, open the pork and a fresh pan of everything else. My delivery team labels every pan by filling, so you can find the pork without lifting lids, and the FAQ page has the reheating notes if the party runs long enough to need them.

For a cake-and-presents party, the food line usually opens about forty-five minutes after the start time. Tell me that hour when you request the quote and I will time the delivery to it, not to the moment the first guest arrives.

Ages change the number

Under five

Toddlers and preschoolers eat almost nothing at a party, but their parents eat and stay. Count the adults at full, the toddlers at zero, and add a plain option: rice, a chicken tamal cut small with no salsa, fruit. A first birthday is really a party for the adults, which is why I wrote first birthday party food ideas around feeding the grown-ups while the baby eats cake.

Five to eleven

This is the half-portion crowd, and the snack table is what makes the rule hold. One tamal, a scoop of rice, chips, fruit. Cut the tamales in half and they go further and get eaten instead of abandoned.

Twelve and up

Count them as adults, and if they have just come off a field, count them as hungry adults. A graduation party is the extreme case of this, a room full of eighteen-year-olds who eat three tamales and come back, and I sized that party separately in graduation party catering.

Ready to feed 30 adults and 25 kids?

If you are planning a birthday, a baptism lunch or a backyard afternoon in Plano, Richardson or anywhere in north Dallas, tell me the date, how many adults, how many children and their rough ages. I will do the half-guest math, send a menu from Maggie’s Tamales with the chicken and pork split for your crowd, and price it the same business day. Request a catering quote for your family party and put the kids’ ages in the notes; that one line is worth a dozen tamales either way.

Frequently asked questions

How much party food do I need for kids and adults?

Count each child between three and eleven as half an adult, teenagers as full adults, and children under three as zero. Then order two big tamales per adult portion when rice, beans and chips are on the table, or three per portion when the tamales are the whole meal. For 25 adults and 25 kids that is about 38 portions, 75 tamales with sides, rounded up to seven dozen.

How many tamales should I order for a kids’ birthday party?

Plan one full-size tamal per child aged three to eleven and two per adult, then round up to the next dozen. A party of 20 children and 20 adults needs about 60 tamales, which is five dozen. Lean the children’s share toward chicken in green salsa with the salsa on the side, and cut the tamales in half on the plate so they are the right size for small hands.

Do kids like tamales?

Most do, especially the chicken tamal in green tomatillo salsa, which is mild and soft and easy to hold. Ask for the salsa on the side for the children’s portion and there is no heat at all in the tamal itself. The pork in red salsa has a little kick that older kids enjoy and younger ones often skip. Plain rice and beans alongside give the pickiest child a safe plate.

Should I set up a separate kids’ table for food?

A separate snack table, yes; a separate meal, usually no. Put out chips, cut fruit and vegetables an hour before the main food so the children eat while they are hungriest and are half full by the time the tamales come out. Then let them go through the same buffet as the adults, first, with one pan open. It keeps the order smaller and the food hotter for the adults who eat later.

What if more kids show up than I planned for?

Round up to the next dozen when you order and you will usually have the cushion. If a few extra children arrive, cut the tamales in half and put out more rice; a half tamal with rice is a full plate for a seven-year-old. Leftovers are never wasted, because tamales in their husks go straight into the refrigerator and steam back to life the next day.
