Hershey Bar Dimensions

When people think of chocolate, there’s probably one brand that pops into mind: Hershey’s. The first Hershey Bar was invented in 1900, making it one of the oldest candy bars to date. As often as we find ourselves around Hershey’s chocolate bars, we never really pay attention to their dimensions.

The measurements of a 1.55-ounce bar of Hershey’s chocolate measures 5.375 inches long, 2.25 inches wide, and 0.25 inches thick. Following the lines, a single Hershey bar can be broken into 12 equal pieces measuring roughly 1.34 × 0.75 × 0.25 inches.

There’s still so much more we can learn about Hershey’s chocolate bars. Today, I’ll cover the dimensions of Hershey’s bars, what it’s made of, and its nutrition facts.

History of Hershey’s Chocolate Bars

Milton S. Hershey had been in the confectionary game for several years before coming up with the iconic Hershey bar we know today. His interest in starting a chocolate company was sparked after seeing German machines effortlessly popping out chocolate bar after chocolate bar in Chicago. At the time, he wasn’t a very well-known figure in the candy industry, but that would change in a few short years.

After picking up the right machinery, Milton immediately went to work. He started the Hershey Chocolate Company in 1894, creating a line of chocolate products that stood out from the unsweetened, baking chocolate products that were more prominent at the time.

After coming up with the perfect milk chocolate recipe in 1899, all Milton had to do was kick-start the mass-production process, and boom! On November 11, 1900, the world saw its first Hershey bar.

If you’re interested in learning more about the struggles Milton went through when coming up with his infamous chocolate bars, I urge you to check out this piece.

Standard hershey bar size

From the get-go, Milton molded the milk chocolate into rectangular bars that weighed precisely 1.55 ounces. The standard 1.55-ounce bar measures 5.375 inches long, 2.25 inches wide, and 0.25 inches thick. Each standard-size bar can be broken into 12 equal-ish pieces that measure approximately 1.34 × 0.75 × 0.25 inches.

Over time, there would be other types of Hershey bars, including the almond variety, that were sold as 1.45-ounce rectangles that measure 5.13 × 1.75 × 0.36 inches. Instead of coming with breakable parts, it is a solid bar of chocolate that has the iconic Hershey logo “stamped” onto it.

However, the largest mass-produced Hershey bar you can get your hands on weighs in at a whopping 7.56 ounces. The giant chocolate bar is approximately 6.7 × 3.75 × 0.25 inches, and it has 25 parts that measure the same as each block in the 1.55-ounce size.

But if you’re interested in pounds and pounds of chocolate, then you should take a look at Hershey’s 5-pound behemoths. The dimensions of this bar, which is enough to cause a standard chocolate fountain to overflow, measures 18 inches long, 9 inches wide, and 1 inch thick. Like the 1.45-ounce bar, you’ll need to a knife (or use your teeth) to break it into uneven pieces.

What Are Hershey Bars Made of?

If you take a look at the ingredients list, you’ll find that a Hershey bar contains the following in unspecified quantities:

  • Milk chocolate
  • Sugar
  • Milk
  • Cocoa butter
  • Lactose
  • Milk fat
  • Soy lecithin
  • PGPR
  • Emulsifier
  • Vanillin
  • Artificial flavor

Something that might shock you is that Hershey bars contain butyric acid. While it might sound like just another chemical, it’s actually a common ingredient in parmesan cheese and yogurt, so don’t feel too worried about this!

Hershey Bar Nutrition Facts

I’m not here to preach about the healthiness, or lack thereof, of Hershey bars. Everyone is free to decide how much chocolate to devour in one sitting. However, for the health-conscious wondering whether or not Hershey is healthy or not, the nutrition facts table speaks for itself.

Per 1 serving, which is a full 1.55-ounce bar, you will consume the following:

Saturated Fat—8 grams

Dietary Fiber—1 gram

So, if you’re a fan of chocolate but want something a bit better for you, you should skip the sugar-laden milk chocolate and stick with bitter dark chocolate.

How many Kisses equals a single 1.55-ounce Hershey Bar? 1 Hershey’s Kiss weighs 0.0155 ounces. As such, you would need to unwrap and consume 100 Kisses to get the same chocolatey goodness from a single standard-size bar.
