Crisps are called crisps because of how they feel when you eat them. That sharp, dry snap when you bite down is exactly what the word describes. It’s a straightforward name that stuck, and it stuck because it fits. But the story of how British English landed on “crisps” while Americans went with “chips” involves a bit of naming history, a bit of transatlantic confusion, and a snack that’s older than most people realise.
The name also quietly tells you something about how the British think about food. Texture gets its own word here. That’s not a small thing.
Where the Word “Crisp” Comes From
The Old English Root
The word crisp has been in the English language for centuries. It traces back to the Old English “crisp” and before that to the Latin “crispus”, which originally meant curled or wavy. Over time the meaning shifted. By the medieval period, crisp had come to describe something dry, firm, and quick to break. When thinly sliced, fried potato snacks arrived on the scene, the word was already waiting for them.
Why Texture Got Its Own Name
British food naming tends to be literal. Chips are thick. Crisps are crisp. The logic is right there in the word. When a new food comes along with a defining characteristic, that characteristic often becomes the name. The crunch is what makes a crisp a crisp, so the crunch is what it’s called.
This is different from the American approach. “Potato chips” describes what the snack is made from rather than how it behaves. Neither approach is wrong, but the British version does tell you more about the eating experience before you’ve even opened the bag.
Why the UK Says Crisps and the US Says Chips
The Chip Confusion Problem
In the UK, chips already meant something: the thick-cut fried potato you get with fish. When thin, fried potato slices started appearing in the early twentieth century, calling them chips would have caused real confusion. You’d have no way of knowing whether someone meant a bag of thin, crunchy snacks or a portion of hot, chunky fried potato.
The word crisps solved that problem cleanly. It separated the two things without anyone having to explain themselves every time they ordered.
When “Crisps” Was First Used
The term crisps in the snack food sense is generally traced to the UK in the 1920s. Smiths Crisps, founded in 1920, is widely credited as one of the first commercial crisp brands and helped establish both the product and the name in everyday British vocabulary. By the time the snack became widely available across the country, crisps was the word, and it stayed that way.
If you want the full story of how the crisp industry developed in the UK, the history of Walkers Crisps covers how one brand came to dominate the market from the 1980s onward.
The History of Crisps as a Snack
How Crisps Were Invented
The origin story most people know involves a chef called George Crum, working in Saratoga Springs, New York in 1853. According to the story, a customer kept sending back his fried potatoes for being too thick, so Crum sliced them paper-thin, fried them until they were brittle, and served them as a joke. The customer loved them. Whether that story is entirely accurate is debated, but thin fried potato slices were certainly being made and sold in America by the mid-1800s.
The snack took longer to reach the UK in any organised commercial form. Early crisps were sold loose, often in pubs, sometimes with a small twist of salt in a blue paper sachet so you could season them yourself. If that tradition sounds familiar, it’s because it directly inspired the blue salt bag in crisp packets that a lot of people remember from childhood.
How Crisps Became a British Institution
The commercial crisp industry in Britain took off properly in the 1920s and 1930s. Smiths dominated early on. Golden Wonder launched in 1947. Walkers arrived in 1948. By the time television advertising became widespread in the 1950s and 1960s, crisps were already a fixture in British homes, schools, and pubs.
The range expanded steadily through the following decades. Ready salted gave way to flavoured varieties. Cheese and onion, salt and vinegar, and prawn cocktail all became staples. The UK’s favourite crisp flavours have shifted over time, but the core flavours from that era are still the best-sellers today.
Crisps vs Chips vs Potato Chips: A Quick Guide
What Each Term Means
The same food goes by different names depending on where you are. In the UK, crisps are thin, fried or baked potato snacks sold in bags. Chips are thick-cut fried potatoes, served hot. In the United States, chips or potato chips means what the UK calls crisps. What the US calls fries, the UK calls chips. It’s the same underlying ingredient causing chaos in two different directions.
If you’re ever ordering food abroad, this is the distinction that matters. Asking for chips in a US diner will not get you what you’re expecting.
Are All Crisps Made from Potato?
Not any more. The word crisps now covers a much broader category than it did in the 1920s. Corn-based snacks like Monster Munch and Wotsits sit in the crisp aisle despite containing no potato. Rice-based snacks like Skips do too. The word has stretched to mean any thin, dry, crunchy bagged snack, which is probably not what whoever named them in the 1920s had in mind.
Why Crisps Are Still Called Crisps in 2026
Language That Doesn’t Need Fixing
Some food names get updated as the product evolves. Crisps haven’t needed updating because the name still works. Whatever the base ingredient, the defining quality of a crisp is still the texture: that dry, brittle snap. The word describes the experience accurately whether you’re eating a potato crisp, a corn puff, or a rice snack.
The Word Across the UK
Crisps is consistent across the whole of the UK in a way that some food terms aren’t. There’s no regional variation that causes confusion. Everyone knows what you mean. That kind of universal clarity in food vocabulary is actually quite rare, which is part of why the word has lasted as long as it has.
The fact that you’re reading an article about why crisps are called crisps suggests the name has done its job well enough that people are still curious about it a century later.

Why are crisps called crisps in the UK?
The word crisp describes the texture: that dry, snapping crunch when you bite into one. The term became the standard British name for thin fried potato snacks in the early twentieth century, largely to avoid confusion with chips, which already meant thick-cut fried potatoes in the UK.
When was the word crisps first used?
The term crisps in the snack food sense is generally traced to the UK in the 1920s. Smiths Crisps, founded in 1920, helped establish the word as the standard British name for the product.
Why do Americans say chips instead of crisps?
American English uses chips as a shortening of potato chips, which is what thin fried potato snacks were called in the United States from the mid-1800s. The UK needed a different word because chips already referred to something else: thick-cut fried potatoes.
Who invented crisps?
The most widely repeated origin story credits American chef George Crum with accidentally inventing thin fried potato slices in 1853. Commercial production in the UK began in earnest in the 1920s, with Smiths Crisps among the first major brands.
Are all crisps made from potato?
No. The word crisps now covers corn-based snacks, rice-based snacks, and other ingredients alongside traditional potato crisps. Brands like Monster Munch, Wotsits, and Skips are all sold as crisps despite not being made from potato.
What is the difference between crisps and chips in the UK?
In the UK, crisps are thin, dry, bagged snacks. Chips are thick-cut fried potatoes served hot, usually alongside fish. The two words describe completely different foods, which is exactly why crisps needed its own name when the bagged snack arrived.
