From 17.1 Millimeters to 8.9 Millimeters: The Journey Behind a 48% Reduction in Thickness

Unveiled at Galaxy Unpacked 2025 in New York on July 9, the Galaxy Z Fold7 is 48% thinner than the original Galaxy Fold. While overall thickness[1] declined by 29% across the first six generations — from the Galaxy Fold in 2019 to the Galaxy Z Fold6 in 2024 — a significant 26% reduction was achieved in just the past year. This streamlined design reflects Samsung Electronics’ continued advancements in hinge engineering and product design, delivering a more refined user experience.

To highlight this milestone, Samsung Newsroom explores how the Galaxy Z Fold series has redefined thinness in foldable smartphones from 2019 to today.

Making its debut in 2019, the Galaxy Fold was Samsung’s first device to introduce the concept of foldable smartphones. With a maximum folded thickness[2] of 17.1 mm and a maximum unfolded thickness of 7.6 mm, the device offered the public its first look at foldable display technology. This revolutionary form factor ushered in a new mobile experience, allowing users to enjoy a widescreen display from the palm of their hand.

Introduced in 2020, the Galaxy Z Fold2 featured the Hideaway Hinge — consisting of more than 60 internal components for smoother, more flexible folding. The precision-engineered hinge integrated seamlessly into the device’s body, reducing the maximum folded thickness to 16.8mm and a maximum unfolded thickness to 6.9 mm.

In 2021, the Galaxy Z Fold3 became even more compact — measuring a maximum thickness of 16.0 mm when folded and 6.4 mm when unfolded — while also introducing support for the S Pen and IPX8-rated water resistance, both firsts for the series. Armor Aluminum was applied throughout the device to boost durability, and the upgraded Sweeper technology helped prevent dust and foreign particles from entering the hinge. These enhancements enabled a thinner, sturdier design without compromising usability.

Released in 2022, the Galaxy Z Fold4 brought notable improvements in both weight and thickness. The gear-based hinge was replaced with a linear movement mechanism, reducing internal components and resulting in a maximum folded thickness of 15.8 mm and an unfolded thickness of 6.3 mm. This redesign offered a sleeker profile and improved ergonomics while maintaining the device’s robust performance.

In 2023, the Galaxy Z Fold5 introduced the Flex Hinge, an innovative hinge mechanism with four drive shafts that enabled the display to curl inward in a water-drop shape, replacing the traditional Hideaway Hinge. This advancement enabled the two halves of the phone to close more evenly, minimizing the screen crease and eliminating the gap when folded. The result was a more compact form factor, with a folded thickness of 13.4 mm and an unfolded thickness of 6.1 mm.

Unveiled in 2024, the Galaxy Z Fold6 delivered an even slimmer silhouette — just 12.1 mm when folded and 5.6 mm when unfolded. Featuring a refined structure and design of a symmetrical dual rail hinge, the device could be folded flat or opened to various angles between 75 and 115 degrees for greater versatility. This streamlined build further enhanced portability and everyday usability.

Now the thinnest Galaxy smartphone ever, the Galaxy Z Fold7 embodies years of design evolution. With a folded thickness of just 8.9 mm and an unfolded thickness of 4.2 mm, the device sets a new standard for slim foldables. At the core is the Armor FlexHinge — a new structural innovation that fuses advanced materials with an optimized design for superior durability and compactness. While the cover display of the Galaxy Z Fold6 measures 6.3 inches (158.9 mm), the Galaxy Z Fold7’s cover display extends to 6.5 inches (164.8 mm) to increase usability when the device is folded. The main display[3] also spans 8.0 inches (203.1 mm) when unfolded, offering an 11% larger screen area than its predecessor — the biggest in the Z Fold series to date.

With each new generation, the Galaxy Z Fold series has advanced in both form and function — reducing thickness while expanding what’s possible in a mobile device. At the heart of this progress is Samsung’s continuous innovation in hinge technology. As the Galaxy Z Fold series pushes the boundaries of smartphone design, Samsung remains committed to unlocking transformative experiences with next-generation engineering and a foldable form factor like never before.

Introduced in 2019, the first Galaxy Fold was a completely new form factor that combined the portability of a smartphone with the extensive productivity of a tablet — challenging conventional perceptions of what a smartphone could be. Driven by the bold vision that foldable phones could reconcile two seemingly conflicting demands—large screens and true portability—Samsung looked to other industries for inspiration, engineering a durable hinge and proving that smartphone displays, too, could fold. It was a synthesis of creativity and productivity that unlocked new possibilities – from seamless multitasking on the go to immersive content creation.

But smartphones are constant companions that we tuck into our pockets, use with one hand and take everywhere we go. So it’s only natural that users desire a foldable device that is as easy to carry as it is to use. To that end,  Samsung engineers and designers are refining each generation of the Galaxy Z series to be thinner, lighter and more durable than the last.

This year, that journey reaches a new milestone. The newest Galaxy Z series is the thinnest, lightest and most advanced foldable yet – meticulously crafted and built to last.

The Ultra experience is ready to unfold.

Samsung’s “Flipvertising” campaign – which garnered the Grand Prix in both the Creative Data and Direct categories in 2023 – emphasized the brand’s ongoing commitment to excellence in creative advertising. The campaign took a unique approach to reach audiences by enabling them to take ownership of their own search experience. By flipping traditional advertising concepts on their head, Samsung empowered its Gen Z audience to discover an organic, rewarding journey with the Galaxy Z Flip4, demonstrating Samsung’s expertise in delivering captivating yet authentic campaigns.

“Samsung’s groundbreaking work in blending technology with creativity continues to push the boundaries of what’s possible in marketing.

Despite the current economic climate, global sales of the Galaxy S23 series have been highly positive. TM Roh believes that this was made possible with the coming together of several new mobile innovations developed based on consumer feedback, which sets a new standard in premium smartphone experiences. This includes the advanced camera features in the Galaxy S23 series smartphones, represented by Nightography; smooth gaming experience backed by the devices’ powerful performance; convenient, easy-to-use One UI 5.1; the use of environmentally friendly recycled materials in the Galaxy S23 series and optimization of third-party apps through open collaborations with global partners.

He reiterated that more than ever, consumers are now placing reliability on the top of their list of must-haves. TM Roh said, “Our consumers are looking for more reliable products, reliable brands, and premium high-end products that can provide a good experience.”

Three-pronged Approach to Lead in the Mobile Market

Noting that this user preference trend would be one for the long term, he laid out a three-pronged approach that Samsung is taking to effectively respond to challenges in the mobile market, and at the same time, pave the way for Samsung to reinforce its position as a market leader:

• Premium Quality: With Samsung’s flagship mobile devices at the core of this strategy, Samsung is focused on continuously improving the product quality of all Samsung Galaxy devices, ensuring that they deliver not just on the user experience, but also in empowering consumers to work better the way they want to.
• Enabling New Experiences and Possibilities: Samsung is focusing its efforts on enabling consumers with new experiences and possibilities through their innovative line-up of Galaxy products by continuously creating and providing new innovations and experiences not just in hardware innovations, but also in software and AI, that only Samsung can provide.

For example, Samsung not only pioneered the folding smartphone category but also took foldables mainstream, with the product category growing in popularity globally. This focus on premium experiences is also being driven by features such as the large screen experience on the Galaxy Z Fold series, the enhanced pocketability and selfie experience on the Galaxy Z Flip series, as well as the excellent Nightography and camera capabilities of the Galaxy S23 series, made possible through innovations in AI technology.

• A Galaxy for Everyone: Finally, as much as smartphones are now a part of our everyday lives, there are still many consumers out there who have yet to own a smartphone. As such, Samsung wants to make Galaxy devices more accessible to all, and at more affordable price points, to help more users to live their best lives.

In Vietnam, Samsung has recently launched Samsung Finance+, which allows customers to own Samsung Galaxy mobile devices with quick, convenient, and assured micro-financing options provided by financial partners, at Samsung Experience Stores. Samsung Finance+ is currently also available to consumers in Thailand and Indonesia.

Delivering Great Mobile Experiences for All

“At the MX Business in Samsung Electronics, our goal is to provide a great experience to meet the needs of consumers, both now and in the future, through products of various segments,” emphasized TM Roh.

Guided by a firm understanding of the needs and preferences of consumers from different regions and segments, we want to ensure that we are delivering various quality mobile experiences that consumers want. This is especially important in the diverse markets of the Southeast Asia and Oceania region.

“For consumers who are looking for premium smartphones, we offer the Galaxy S series and foldable devices. For those looking for something more affordable yet be able to enjoy mobile experiences powered by 5G connectivity, we have the Galaxy A series,” he explained.

Innovating for the Future

Looking ahead, TM Roh said that consumers across Southeast Asia and Oceania and globally are increasingly expecting a more seamless device experience, centered on the ubiquitous smartphone.

He cites the Galaxy ecosystem, with smartphones, wearables, and tablets, as an example of this unmatched, continued experience that can simplify consumers’ lives. “We’ve strengthened our entire multi-device experience to allow Galaxy devices to better connect with our TV line and home appliances such as air conditioners, and refrigerators. This is one of our biggest strengths that differentiates the Galaxy ecosystem from competitors. We will continue to build a more powerful and seamless multi-device experience, including strengthening localization efforts to optimize how technology can blend into the everyday for our users through our SmartThings platform.”

TM Roh believes that there is still much potential to innovate in the mobile market across many areas. The innovation of form factors, such as foldables, will enrich the whole ecosystem, driving the development of third-party apps and new user experiences and that continue to redefine the limits of what a mobile device can do.

He also mentioned how the partnership with Google and Qualcomm, announced at Galaxy Unpacked 2023, will explore new possibilities for extended reality (XR) applications, while the creation of new AI-powered services and content, or intelligent in-vehicle experiences and even smarter home appliances, will also contribute towards smartphone innovation in the years to come.

“We will be kept busy bringing new innovations to our consumers. The whole smartphone and mobile industry will continue to evolve and grow in the future.”
