Eastern Traditions: Chinese scroll paintings and Japanese folding screens (Byōbu) used varying ratios to enhance storytelling and adapt to different spaces.
Islamic Art: Geometric patterns adhered to specific proportional rules, seamlessly integrating with architectural elements.
Aspect ratios have long been fundamental to visual balance and storytelling in art, paving the way for their crucial role in modern media.
The Expanding Canvas: How Technology Widened Our View
The Early Days of Photography
As we move into more recent history, early photographs were often circular due to lens limitations. As technology improved, the square format became popular, offering a balanced, symmetrical canvas for portraits and landscapes alike.
The Rise of Cinema
With the advent of motion pictures, new aspect ratios emerged. The silent film era standardized on a 4:3 ratio, which would later become the norm for television broadcasts. This near-square format provided a versatile canvas for both close-ups and wide shots.
Polyvision: The Widest Aspect Ratio of Its Time
In 1927, the film "Napoleon" introduced Polyvision, an innovative technique that used a 4:1 aspect ratio.
Polyvision involved the simultaneous projection of three reels of film arrayed in a horizontal row, creating an extremely wide viewing experience. This aspect ratio was the widest yet seen, even though it was technically created by projecting three film reels side by side.
Interestingly, a similar aspect ratio of 32:9 has recently gained popularity among PC gamers and multitaskers, showing how historical innovations can find new life in modern technology.
Cinemascope: Widening the Horizon
In the 1950s, Hollywood introduced Cinemascope, with its ultra-wide 2.35:1 aspect ratio. This panoramic format revolutionized the cinematic experience, allowing filmmakers to capture sweeping landscapes and epic scenes.
The Television Era: 4:3 Becomes the Home Standard
By the 1950s television replaced radio as the dominant broadcast medium taking over home entertainment. Approximately 8,000 U.S. households had television sets in 1946; 45.7 million had them by 1960. As television entered homes across the world, the 4:3 aspect ratio became ubiquitous. This format, inherited from film, shaped broadcast content for decades.
The Widescreen Revolution: 16:9 Takes Over
The shift to 16:9 widescreen format marked a significant evolution in visual content. This aspect ratio, closer to human peripheral vision, offered a more immersive viewing experience. It quickly became the standard for HD television, computer monitors, and digital video.
The Social Media Effect: Square and Vertical Video
Instagram and the Return of the Square
Instagram's launch in 2010 brought the 1:1 square ratio back into vogue, by only allowing this aspect ratio for uploaded photos and videos. This format, perfect for mobile viewing, challenged brands to rethink their visual strategies.
It wasn't until August 27, 2015, that Instagram launched its landscape video capability. The Star Wars account was given the opportunity to showcase/reveal this new feature, sharing a teaser for the highly anticipated film "Star Wars: The Force Awakens" in a 16:9 widescreen format.
The Rise of the Smartphone and Vertical Video
The evolution of smartphone aspect ratios has been a journey of continuous innovation, driven by advances in technology and changing user preferences. From the early 2:3 ratio of the original iPhone, which balanced portrait and landscape orientations, we've seen a steady progression towards taller screens. The 3:5 ratio of the early 2010s gave way to the 9:16 format in the mid-2010s, culminating in today's even taller 6:13 ratios seen in devices like the iPhone 12 Pro and Samsung Galaxy S21. These changes have allowed for more screen real estate while maintaining a narrow, easily-handled form factor.
This hardware evolution has been accompanied by, and often driven by, changes in content consumption habits, particularly the rise of vertical video. Platforms like Snapchat pioneered the format, with Instagram Stories and TikTok following suit and cementing vertical video as the dominant mobile-first content type. This shift and subsequent industry-wide adaptation to vertical video has forced brands, content creators, and even traditional media companies to rethink their visual storytelling strategies.

As VR evolves, it's not just changing how we view content—it's transforming how we interact with digital environments entirely.
Traditional concepts of aspect ratios become less relevant in a medium where the viewer is fully immersed in a 360-degree environment, presenting both challenges and opportunities for content creators and brands to rethink how visual content is conceived and produced.
Mathematical Marvels: Ratios That Shape Our World
While much of our discussion has focused on aspect ratios in visual media, it's worth exploring some mathematical ratios that have profoundly influenced art, design, and even our perception of beauty. These ratios demonstrate how mathematical principles can have far-reaching impacts on visual aesthetics and practical applications.
The Golden Ratio: Nature's Design Principle
No discussion of significant ratios would be complete without mentioning the golden ratio, approximately 1.618:1. Also known as phi (φ), this ratio has captivated mathematicians, artists, and designers for millennia.
The golden ratio is often found in nature, from the spiral of a nautilus shell to the arrangement of leaves on some plants. Its prevalence in the natural world has led many to consider it inherently aesthetically pleasing to the human eye.
In art and design, the golden ratio has been used consciously (and sometimes subconsciously) to create harmonious compositions. The ancient Greeks used it in architecture, most famously in the Parthenon. Renaissance artists like Leonardo da Vinci incorporated it into their paintings. Even in modern times, the golden ratio influences logo design, web layouts, and product packaging.
Interestingly, some researchers argue that the widespread belief in the aesthetic superiority of the golden ratio might be overstated. Nevertheless, its historical significance and continued use in design make it a crucial ratio to understand in the context of visual composition.
The Silver Ratio and the Square Root of 2: A Dual-Purpose Marvel
An intriguing aspect ratio worth exploring is the square root of 2 (approximately 1.414:1). This irrational number, which also happens to be known as the silver ratio, serves a dual purpose in both practical applications and aesthetic design.
As the silver ratio, also known as the silver mean or silver constant, it's derived from the equation x^2 = x + 1. Some designers consider it to be more harmonious in certain applications than the golden ratio, particularly in situations where the golden ratio might produce proportions that are too extreme. Some argue that the silver ratio is especially suitable for digital interfaces, as it often aligns well with common screen aspect ratios.
The silver ratio appears in various mathematical concepts, including the sequence of Pell numbers (similar to the Fibonacci sequence, which is related to the golden ratio). It also shows up in geometry: a regular octagon can be divided into a square and four equal rectangles, each with the proportions of the silver ratio.
Coincidentally, this same ratio forms the basis for one of the most widely used paper size standards in the world. The square root of 2 ratio is the foundation of the ISO 216 standard, which includes the familiar A4 paper size. What makes this ratio special is its unique property: when a rectangle with this proportion is cut in half parallel to its short side, the resulting two rectangles have the same aspect ratio as the original. This property allows for consistent scaling between paper sizes (A4 to A3, A5 to A4, etc.) without changing the proportions.
This elegant mathematical solution to a practical problem showcases how aspect ratios can be both aesthetically pleasing and functionally optimal. The square root of 2 ratio has found applications beyond paper sizes, influencing everything from book design to architecture.
The Impact on Visual Media, Design, and Marketing

The rise of vertical video, driven by mobile-first consumption habits, has pushed creatives to prioritize content that feels native to smartphone screens. At the same time, wider and more immersive formats have opened up new possibilities for engaging brand narratives, allowing for more cinematic and expansive storytelling.
The influence of aspect ratios extends beyond mere practicality into the realm of aesthetics and design principles. Mathematical ratios like the golden ratio (1.618:1) and the silver ratio (1.414:1) continue to inform compositional choices across various media. Filmmakers might use these ratios to frame pivotal shots, while graphic designers leverage them to create balanced layouts for both digital and print media. The practical application of the square root of 2 ratio in paper sizes demonstrates how these mathematical principles can solve real-world design challenges. As we venture into new frontiers like virtual reality and volumetric video, these timeless principles serve as a bridge between traditional design wisdom and cutting-edge technology.
As we continue to push the boundaries of what's possible in visual storytelling, understanding the interplay between aspect ratios, mathematical principles, and human perception becomes increasingly crucial.

This shift towards more immersive and interactive content is pushing brands and creators to think beyond static aspect ratios, considering how their visual stories can adapt and respond to user engagement.
The Future of Visual Storytelling: Volumetric Capture and Beyond
Volumetric Video: A New Dimension
Volumetric video or volumetric capture is emerging as the next frontier in immersive content, pushing the boundaries of traditional aspect ratios and two-dimensional thinking. This groundbreaking technology creates three-dimensional video that can be viewed from any angle, offering unparalleled realism and interactivity. Unlike traditional video or even 360-degree footage, volumetric capture records the entire volume of a space, including depth information. The process involves an array of cameras and depth sensors that capture a subject or scene from multiple angles simultaneously. This data is then processed to create a three-dimensional model that can be rendered in real-time, allowing for six degrees of freedom (6DoF) - the ability to move forward/backward, up/down, left/right, and rotate along three perpendicular axes.
The implications of volumetric video for various industries are profound. In entertainment, it opens up new possibilities for immersive storytelling, allowing viewers to explore scenes from any angle and even interact with the environment. Sports broadcasting could allow fans to view games from any position on the field, while education and training fields could create highly detailed, interactive simulations. For brands and advertisers, it offers unprecedented opportunities for product demonstrations and immersive brand experiences, such as virtual showrooms where customers can examine products in detail from every angle. As the technology continues to advance and become more accessible, we can expect to see volumetric video reshape our understanding of visual media, pushing us further beyond the constraints of traditional aspect ratios into a fully three-dimensional visual paradigm.

Ray Kurzweil's Foglets: Reshaping Reality Itself
Ray Kurzweil, a renowned futurist and inventor, has proposed a concept that pushes the boundaries of reality manipulation even further than Full Dive VR: "foglets." These hypothetical microscopic robots would work in swarms to manipulate matter at a molecular level, potentially creating or altering physical objects and environments in real-time. Kurzweil envisions foglets as a key component of a future "utility fog" - a cloud of nanobots that can take on any shape or properties. Each foglet would be a tiny robot that can exert force in multiple directions and connect to other foglets to form larger structures. They could create or mimic any object or environment through coordinated action, potentially manipulating light, sound, and other sensory inputs directly.
The implications of foglet technology for visual storytelling and experiences are profound and far-reaching. If realized, foglets could transform any space into an interactive, changeable canvas, fundamentally altering how we think about visual storytelling and aspect ratios. Product demonstrations could materialize on demand, allowing customers to interact with them in ways impossible with current technology. Entire brand environments could be created and changed dynamically, offering unprecedented levels of customer engagement. Advertisements could physically adapt to individual viewers, changing not just content but form to maximize appeal.
However, the challenges in developing such technology are equally significant. Creating functional nanobots at scale remains a monumental task, and ensuring that swarms of nanobots behave as intended without unintended consequences presents complex control and safety issues. Moreover, the ethical implications and regulatory hurdles surrounding such reality-altering technology are substantial. While foglets remain in the realm of speculation, the underlying concepts of environmental control and sensory manipulation they represent are likely to influence future developments in marketing and storytelling technologies, pushing us to reimagine the very nature of visual media and aspect ratios.
