Most popular Halloween candy weighs under 20 grams per fun size pack

M&M's now sit at the top of the most popular Halloween candy list, and a fun size pack of Peanut M&M's weighs just 18 grams. Snickers and Skittles land in the same narrow band, between 15 and 17 grams a piece, which is why a bag that looks enormous at the store can be empty by 7:30 on Halloween night.

You'll spend real money finding that out. The National Retail Federation's 2026 Halloween survey puts candy spending at $4.1 billion this year, with 96% of shoppers planning to buy some. Below are the real weights and calories for the most-bought treats, plus a simple way to work out how many bags your door actually needs.

Most popular Halloween candy, ranked by sales

The ranking that gets quoted every October comes from CandyStore.com, a bulk candy seller that looked at 17 years of its own sales in the months before Halloween. In its latest national list, reported by Fox Business, M&M's took first place and pushed Reese's Peanut Butter Cups into second for the first time since the retailer started tracking.

Places six through ten went to Hot Tamales, candy corn, Hershey's Kisses, Hershey's Mini Bars and Butterfinger. That's the data shoppers lean on when they grab bulk Halloween candy, and it's a fair guide to what kids will be hoping for when they ring your bell.

Three of the five best-selling Halloween treats on CandyStore.com's national list, M&M's, Skittles and Starburst, come from one company: Mars.

Why sales rankings beat taste polls

Taste polls tell you what people say they like. Sales data tells you what they actually carried to the register, which is the number that matters when you're deciding what goes in the bowl. State results still vary, though: Fox Business noted Sour Patch Kids topped Nebraska while Jolly Ranchers led Georgia.

Fun size candy weights, piece by piece

Nutrition labels list servings, not grams per piece, so a little division helps. A 10.5 ounce bag of Snickers Fun Size holds 18 bars, according to the retailer label. Ten and a half ounces is about 298 grams, which works out to roughly 16.5 grams per bar. You can check that kind of maths with our ounces to grams converter.

Snickers fun size nutritional value

Each fun size Snickers carries 80 calories and 9 grams of sugar, 8 of them added, per the label on the 18-bar bag. For a bar that weighs about as much as three US nickels, that's a lot of energy packed into a small square.

Fun size Peanut M&Ms calories

One 18 gram pack of fun size Peanut M&M's has 90 calories, with 5 grams of fat, 11 grams of carbs and 2 grams of protein, per FatSecret's nutrition database. The peanuts are why it outweighs the other packs and why it's the only one here with any meaningful protein.

Calories in a Skittles fun size

A Skittles fun size pack weighs 15 grams and has 60 calories, with 14 of those 15 grams coming from carbohydrate, according to FatSecret's entry. It's the lightest and least caloric pack in this lineup by a clear margin.

Halloween candy calories per gram

Dividing calories by weight shows which treats are dense and which are mostly air and sugar. Chocolate and peanuts carry fat, and fat has more than twice the energy of sugar, so the chocolate bars come out on top.

Candy corn calories by the kernel

Brach's lists a serving as 15 pieces with 110 calories and 23 grams of sugar, and its 20 ounce bag holds 18 servings. That's 270 kernels in about 567 grams, so each one weighs close to 2.1 grams and carries roughly 7 calories.

Candy corn shows up on plenty of worst Halloween candy lists, yet it still ranked seventh in CandyStore.com's national sales. People complain about it and buy it anyway.

How much Halloween candy to buy, done by weight

Mars Wrigley and the delivery service Shipt published a formula in 2021 that's still the easiest way to plan. It counts what you'll hand out and what your household will snack on before the big night, then turns pieces into bags.

Here's a worked example. Three hours at 20 kids an hour, two pieces each, is 120 pieces. Two adults who buy three days early and each eat two a day add 12 more, for 132. In 18-bar Snickers bags that's 7.3, so you buy 8. By weight, 132 bars at 16.5 grams is about 2,180 grams, or 4.8 pounds, which you can double-check with the grams to pounds converter.

Buying bulk Halloween candy by the pound

Big variety bags list a net weight and a piece count, and dividing one by the other tells you the real size of each treat. Two bags with the same net weight can hold very different counts, so the one with lighter pieces stretches further at the door.

What the weights mean for your budget and leftovers

The NRF expects the average shopper to spend $115.14 on Halloween this year, and candy is the biggest single line in that budget. Grams per piece is the quiet number that decides whether that money covers every kid or leaves a bowl of extras on your counter.

If your goal is the most handouts for the least candy, the lighter packs win. If your goal is the house kids talk about, the heavier chocolate packs feel more generous, and that 3 gram difference per pack is what you're paying for.

Check fun size candy weight at home

Package weights are averages, so a quick check on your own bag is worth it. Weigh 10 pieces together and divide by 10; it smooths out the small swings between individual bars. If your readings look off, our guide to calibrating a digital scale with a nickel takes two minutes.
