How Many M&Ms Are in a Snack Size Bag? Unpacking the Sweet Mystery

5 min read

According to one study, the average number of M&Ms in a "Fun Size" bag is around 17 pieces, but the quantity can fluctuate from 15 to 19 candies. This variation is a common point of curiosity for anyone asking how many M&Ms are in a snack size bag.

Quick Summary

Snack size M&M bags are filled by weight, not a precise count, leading to natural variations in the number of candies. Factors like factory location and specific product variety further influence the final candy count in each pouch.

Key Points

  • Count Varies by Weight: Snack size M&M bags are filled by weight, not a precise candy count, leading to natural variations.

  • Average Is Around 17: For standard milk chocolate "Fun Size" M&Ms, the average count is approximately 17 pieces.

  • Different Fillings Mean Different Counts: Heavier varieties like Peanut or Crispy M&Ms will have a lower candy count per bag to meet the target weight.

  • Factory Location Matters for Color: Different factories use different formulas for color distribution, meaning the color mix in your bag can vary depending on where it was produced.

  • Born for War: M&Ms were originally invented to provide soldiers with melt-proof chocolate during World War II.

  • Colors Don't Taste Different: The classic milk chocolate M&Ms all have the same flavor regardless of their shell color.

The Average Count: A Delicious Range

While it would be convenient if every snack size bag contained a uniform number of M&Ms, the reality is more varied. The average count for a standard milk chocolate "Fun Size" bag, which is a common snack size, hovers around 17 candies. However, this number is an average, and you might find anywhere from 15 to 19 M&Ms inside your individual pack. This seemingly random variation is not a mistake; it's a deliberate part of the manufacturing process.

Why the Count Isn't Exact

The primary reason for the variation is that M&Ms are packaged by weight, not by an exact count of pieces. Production lines use highly accurate scales to ensure that each bag contains the specified net weight, typically around 0.47 ounces for a "Fun Size" pouch. Because individual M&Ms can differ slightly in size and weight, a bag filled to the correct weight will not always have the same number of pieces as another. This is standard practice in the confectionery industry to ensure consistent product volume and value for consumers.

Factors Influencing Your M&M Count

Beyond the weight-based packaging, several other factors contribute to the exact number of M&Ms you might find in your bag:

  • Flavor and Filling: The size and density of the M&M variety directly impact the count. For instance, a snack size bag of peanut M&Ms will contain far fewer pieces than a bag of milk chocolate M&Ms because the peanuts are much heavier individually.
  • Factory Location: As surprising as it may seem, the factory where your M&Ms were made can also influence the mix. Mars, Inc. has two main M&Ms factories in the U.S., one in Hackettstown, New Jersey (HKP) and another in Cleveland, Tennessee (CLV). A statistician's research confirmed that these two plants use different formulas for the color distribution in their plain M&Ms. While this primarily affects color ratios, it can slightly influence the overall density of the candy mix.
  • Miniature vs. Regular Size: The comparison is not always fair. When considering different versions of M&Ms, such as the Minis sold in tubes, the chocolate-to-shell ratio is different, and the pieces are smaller. This means a "snack size" bag could, in theory, contain a wildly different number of candies depending on whether it holds regular M&Ms or the much smaller Minis.

Milk Chocolate vs. Peanut vs. Crispy: A Comparison

To illustrate how different varieties can affect the count, consider a comparison of three popular M&M flavors in their snack-size packaging. The counts are estimates based on weighing and sampling, since Mars packages by weight, not by a fixed number.

Average Candy Count ~17-18 candies ~9-11 candies [Derived] ~12-14 candies [Derived]
Bag Net Weight (approx.) 0.47 ounces 0.63 ounces 0.58 ounces
Calories per Bag (approx.) ~65-70 calories ~90 calories ~90 calories

Fun Facts from M&M's History

The story behind these chocolate candies is as colorful as the shells themselves. Here are some interesting historical tidbits:

  • Wartime Invention: M&M's were created during World War II, based on the observation that soldiers in the Spanish Civil War were eating chocolate pellets with a hard sugar shell to prevent melting. This allowed chocolate to be transported to soldiers in warm climates without turning to liquid.
  • The Original M&M's: When M&M's were first sold to the public in the late 1940s, they came in a brown pouch instead of the cardboard tubes used for the military. The original colors included brown, yellow, red, green, and violet, though violet was later replaced with tan.
  • The First Candy in Space: In 1981, M&M's became the first candy to travel into space when space shuttle astronauts included them in their food supply. Astronauts still take them on missions today, sometimes tossing them around in zero gravity for fun.
  • A Temporary Absence of Red: In 1976, M&M's temporarily removed the red candies from their bags to avoid confusion with Red Dye No. 2, which had been banned despite not being used in M&M's. The iconic color returned in 1987.

How to Estimate the M&Ms in Your Own Bag

If you want to perform your own experiment to get a more accurate count from a sample, you can follow a simple weight-based method:

  1. Count and Weigh a Sample: Open a single bag and count the number of M&Ms inside. Use a digital kitchen scale to get the weight of that sample in grams. This will give you a benchmark for the weight of the bag's contents.
  2. Find the Average Weight: Divide the total weight of your sample by the number of candies to determine the average weight of a single M&M for that specific flavor and size.
  3. Weigh a Full Bag: Weigh a new, unopened snack size bag. You might have to subtract the packaging weight for more precision.
  4. Estimate the Total Count: Divide the weight of the new bag's contents by the average weight you calculated in step 2. The result will give you a close approximation of the number of M&Ms inside.

The Variable Color Distribution

For those curious about the colors, statistics from 2017 revealed that different Mars factories package different ratios of M&M colors. For plain M&M's, the color percentages were:

  • Hackettstown, NJ Plant (HKP):
    • Blue: 25%
    • Orange: 25%
    • Yellow: 12.5%
    • Green: 12.5%
    • Red: 12.5%
    • Brown: 12.5%
  • Cleveland, TN Plant (CLV):
    • Red: 13.1%
    • Orange: 20.5%
    • Yellow: 13.5%
    • Green: 19.8%
    • Blue: 20.7%
    • Brown: 12.4%

Conclusion: The Final Count is a Delicious Mystery

Ultimately, the precise number of M&Ms in a snack size bag is a delicious mystery, but one that is easily understood when you know the variables involved. The packaging process, which prioritizes filling by weight, combined with slight variations in individual candies and flavor differences, means that no two bags will ever be exactly the same. The next time you open a pack, don't worry about the exact number, but instead enjoy the surprise and the sweet, melt-in-your-mouth flavor that has made this candy a classic for decades.

Frequently Asked Questions

The number of M&Ms varies because the bags are filled by weight, not by a specific candy count. Manufacturers use precise scales to ensure each bag meets its stated net weight, leading to slight variations in the number of candies.

A standard milk chocolate "Fun Size" bag of M&Ms contains approximately 65 to 70 calories. Other varieties like Peanut M&Ms have a slightly higher calorie count per bag.

The color distribution is not entirely random and can vary between different manufacturing facilities. A 2017 study found that the Hackettstown, NJ, and Cleveland, TN, factories use different color ratios for their plain M&M's.

The two M's in M&M's stand for Mars and Murrie, referring to Forrest Mars (son of the Mars company founder) and Bruce Murrie (son of the Hershey president), who collaborated to create the candy.

For classic milk chocolate M&Ms, the different colored shells are just that—different colors. The chocolate filling is the same, so they all taste the same.

While the snack size varies, some reports indicate a typical 1.69-ounce bag of plain M&M's contains around 56 candies, though this number is also an average due to weight-based packaging.

The red M&M's were discontinued between 1976 and 1987 due to public concern over a food dye (Red Dye No. 2) that was found to be carcinogenic. Although M&M's did not use that specific dye, the company temporarily removed the red candies to avoid any consumer confusion or worry.
