Fridge magnets: A definitive history

Fridge magnets. You collect them when in your travels and get them as keepsakes from friends or from the pizza place around the corner. You use them to fix little odds and ends to your fridge: family pictures, unpaid bills, shopping lists, reminders of urgent to-dos from months ago

If you're like most people, you may not give your fridge magnets much thought at all. They're kind of just there, staring from their cool abode while you come and go.

But at some point, these little collectibles became a part of our daily lives. When and how did that happen? Today we'll take a look at the history of fridge magnets and how they found their way to everyone's homes.

The origins of magnets

To no one's surprise, the story of fridge magnets is tied closely to that of fridges. Magnets themselves, however, had been around a while. Lodestones — a type of magnetized iron ore — had been discovered as far back as 2500 BC, and magnetic properties had been employed in compasses since the year 1100 or so.

But while magnets were no novelty when the first commercial fridges were made available, just before the 1920s, it was only around that time that the newly-discovered, more permanent steel magnets started finding their way into commercial applications, such as early electric motors and generators.

The 1950s: The early years

The 1950s marked a turning point—not for magnets themselves, but for refrigerator design. As enameled steel became the industry standard, refrigerators gained a smooth, durable, and, most importantly, magnetic surface

At first, this change was purely practical, making fridges easier to clean and available in a variety of colors to match the booming post-war consumer culture. But unintentionally, it also set the stage for something new. With metallic doors now common in homes, magnets suddenly had a new purpose beyond industrial applications.

The biggest innovation in refrigerators and magnets came with the introduction of the alnico magnetic alloy, which replaced traditional door latches. This upgrade made fridge doors more reliable and eliminated the safety risks posed to children by older latch mechanisms.

Although decorative fridge magnets weren’t yet a widespread trend, the conditions were now perfect. In the coming decades, as advertising, tourism, and household organization grew, the humble fridge door would transform into a display board for reminders, souvenirs, and personal expression.

The 1960s: The dawn of decorative fridge magnets

In the 1960s, refrigerator magnets were a far cry from the sleek, colorful, flat designs we’re used to today. They were more rudimentary, often clunky, and reflected the materials and manufacturing limits of the time.

Fridge magnets existed but weren’t the flexible, fully magnetic items we associate with the term now. Early in the decade, they were typically small, rigid objects—think ceramic or plastic shapes with a tiny, hard magnet glued or embedded on the back. These weren’t "magnets" in the modern sense where the whole thing sticks; the magnet was just a component.

Common designs included basic geometric shapes, letters, numbers, or simple figurines—like fruit, animals, or advertising logos. They were often chunky, with the magnet (usually a brittle ferrite or alnico type) protruding slightly, making them less flush against the fridge.

Colors were limited—muted reds, blues, yellows, or plain white—due to basic painting or molding tech. They were usually imported from Hong Kong or Japan.

At this stage, fridge magnets were still more functional than fun. That changed late in the decade when Sam Hardcastle, an inventor and mold maker working with the space industry, was tasked with designing magnetic letters and numbers for use on large metallic charts.

Instead of using traditional magnetic materials, he experimented with mixing iron oxide (essentially rust powder) with vinyl, creating a flexible, fully magnetic material—meaning the entire object, not just a glued-on piece, stuck to metal.

Hardcastle founded a company called Ad Specialities. His company produced molded, three-dimensional items, often hand-painted or dipped in vinyl. If you were around in the 1960s and 1970s, you probably remember one of Harcastle's most iconic creations: state-shaped magnets (like Missouri or Texas) about a quarter-inch thick, with raised details—maybe a little cow or cactus for flair.

They weren’t flat like today’s printed ones; they had a tactile, sculpted feel, sometimes with a glossy finish. Colors got bolder as vinyl allowed it—bright reds, greens, or blues—but still not the photo-realistic prints we see now. These magnets were bigger and heavier than earlier versions, designed to hold papers securely, and often doubled as souvenirs or promo giveaways.

Today, Ad Specialities no longer exists, a company named Ideaman, Incorporated was founded in 1992 and continues to produce magnets true to Hardcastle's original designs as Classic Magnets.

The 1970s: Fridge magnets become fun

The evolution of fridge magnets took a significant step forward in 1972 with the release of Fisher-Price's iconic "School Days Desk"—an educational toy featuring colorful magnetic letters and numbers. While similar concepts had been introduced earlier by companies like Child Guidance, Fisher-Price’s version was a game-changer.

These game sets included their own metal boards, but was there really a need for that? Inevitably, all those eye-catching magnetic characters would end up in the biggest piece of metal in every household: the fridge.

Around the same time, another inventor, William Zimmerman, went into the fridge magnet business with his "Magic Magnets", flat magnets with cartoon figures, smiley faces, and other playful characters. His magnets also included funny or inspirational phrases (show photo of funny magnet).

Zimmerman was also the first to score a contract to make the first refrigerator magnets for the Walt Disney Company, while his son formed a rival magnet company landing a contract to make magnets for the Peanuts franchise.

The introduction of magnets featuring popular intellectual properties was a turning point in refrigerator magnet history. Cartoon characters, television mascots, and movie tie-ins became widely available, marking the beginning of fridge magnets as collectibles rather than just decorations.

With the new popularity, fridge magnets soon attained collectible status. A teacher who owns one of the largest collections of magnets in Britain, for instance, was started as far back as 1987. And the largest currently on record? That's a mere 35.000-fridge magnet collection, proudly owned by Louise Greenfarb of Las Vegas, who's collected them since the '70s.

(If you're jealous, don't be. Start now and you, too, may have a few tens of thousands of little refrigerator magnets in… fifty years. Just don't expect to have your fridge hold them all!)

The 1980s: The golden age of fridge magnets

During the 1980s and 1990s, fridge magnets surged even further in popularity. From simple promotional tools, they now turned into widespread collectibles and decorative items.

Around the world, souvenir shops began mass-producing magnets featuring landmarks, flags, and cultural symbols, turning them into must-have travel mementos. At the same time, brands and businesses ramped up their use of flexible rubberized magnets for advertising, offering customers free, practical reminders of their services.

Advances in manufacturing—particularly the use of flexible, lightweight magnetic strips made from ferrite powder and rubber—made it cheap and easy to mass-produce magnets in all shapes and sizes. The availability of injection-molded magnets also allowed for more intricate and colorful designs, making novelty magnets a common sight in homes.

Fridge magnets take on new roles

One of the biggest trends of the decade was mass-produced souvenir magnets. While travel-related magnets had been around in earlier years, the 1980s saw an unprecedented boom. Gift shops in major cities, tourist attractions, and amusement parks stocked magnets featuring landmarks, mascots, and state-themed designs.

Another major development of the decade was the rise of kitsch and novelty magnets. Companies embraced magnets as a form of self-expression, creating designs with funny slogans, cartoon characters, and pop culture references. Flexible magnetic sheets allowed for endless creativity. These were impulse buys at gift shops or party favors, adding a splash of personality to suburban kitchens.

Finally, promotional magnets became ubiquitous. Local businesses—from pizza places to real estate agents—began handing out fridge magnets as a way to keep their contact information front and center. Companies began competing with each other for an increasingly shrinking share of real estate on refrigerators.

The 1990s: Fridge magnets get even more creative

The 1990s saw photo-realistic printed magnets emerge, turning fridges into mini photo albums. Families and businesses alike embraced high-resolution images for both personal keepsakes and colorful promotional giveaways.

Interactive sets—like magnetic poetry kits and mix-and-match face magnets—became kitchen staples, inviting playful word games and silly character mash-ups. At the same time, pop-culture icons from Disney, Looney Tunes, sitcoms, and blockbuster movies continued to lined fridge doors everywhere.

The 2000s: Personalization and mass customization

In the early 2000s, a shift toward personalization dramatically reshaped the world of fridge magnets. Families began using magnets to showcase personal memories, transforming kitchens into galleries of family photos and milestones.

Digital cameras were becoming common, online sharing was on the rise. This led to customized magnets emerging as a popular way to preserve special moments — from milestone birthdays to quiet everyday snapshots.

With mass customization made possible by advances in digital printing and the rise of the online world, customers could now upload their own images to create magnets that were as unique as their personal stories. This new level of personalization led to niche products ranging from custom wedding and baby announcement magnets to personalized holiday cards. Companies quickly adapted their production processes to handle bespoke orders, meeting the growing consumer demand for products that felt intimate and one-of-a-kind.

Retro designs maintained their allure here too, as nostalgia kept classic, souvenir-style magnets in the market. Travelers collected magnets as tangible memories of their adventures, balancing new personalized options with a love for vintage aesthetics. On top of that, material innovations such as thinner, more robust flexible magnetic sheets allowed for larger and more elegant designs.

The 2010s: The digital shift and fridge space decline

The 2010s brought two important changes to the world of magnets.

First, smartphones and digital assistants took over many of the tasks once reserved for fridge magnets. Photos, shopping lists, and appointment reminders all migrated to apps. Magnets consequently lost some of their utility, but held onto their decorative role. What else was there to add color and character to your kitchen décor?

Secondly came the popularization of stainless-steel refrigerators. These became the must-have appliance of the decade, but at a cost: non-magnetic doors for many of them. Suddenly, the classic fridge gallery, cluttered with magnets collected over years and decades, grew sparse. For many households, the beloved habit of pinning up notes went away.

But through all these shifts, the souvenir magnet lost none of its charm. Travelers still bought and traded magnets as small, but tangible reminders of their journeys. On online forums, magnet aficionados even harnessed the power of the internet to trade magnets with other collectors from all over the world.

On fridges, lockers, and office cubicles, fridge magnets proved that even in a digital age, the joy of a physical memento endures.

The 2020s

Thanks to platforms like Etsy, independent artists now sell unique hand-crafted magnets worldwide.

Eco-friendly materials and “buy one, plant one” initiatives reflect growing consumer demand for sustainable, stylish home accessories.

At the same time, 3D printing has unlocked new possibilities: intricate miniatures, interlocking puzzle pieces, and tactile spinners add playfulness to décor. There's a whole new world of possibilities for custom fridge magnets out there.

Custom fridge magnets — a rising trend

One of the biggest trends of all in this decade is customization.

Custom products are everywhere, and fridge magnets are no exception. A family picture, a cute shot of your favorite feline moment, a company logo, or anything else your imagination comes up — whatever it is, you can have it printed, die-cut, and stuck to your fridge in a matter of days — something that just a few years ago only huge companies could dream about.

This, of course, leads us directly to what we at Sticker Mule are all about. Our goal is to continue to democratize the creation—and selling—of custom magnets, which is why we let you create your own flexible or acrylic magnets and sell them on your own Sticker Mule store.

What next for fridge magnets?

Despite the rise of minimalist home aesthetics and digital organization tools, fridge magnets have lost none of their appeal. While our lives turn more and more virtual, our fridge magnets remain a tangible reminder of a more real way of living — adventures we had, perhaps, or moments of connection with family and loved ones.

Collectibles, advertising tools, custom mementos — in whichever shape and form we use them, fridge magnets continue to stick around, both literally and culturally. In fact, not that long ago it was found that over 87% of Americans use refrigerator magnets. Kind of a lot.

Yes, the world went through a lot of change since fridge magnets first brightened our fridge doors. But the little decorative magnetic souvenirs remain unbothered. As long as refrigerators are around, odds are we'll continue sticking fridge magnets to our doors.
