The Pre-Digital Era: A History Of Point Lengths Before Computers
Before the advent of computers, defining point sizes was a complex and highly variable process. The concept originated with the manual typesetting techniques of the printing press, relying on physical type pieces of specific heights. Early typographers aimed for standardization, but regional differences and variations between type foundries made this a significant challenge. Choosing the right type wasn’t just about aesthetics; it was about practical limitations.

The Point System Emerges
The modern point system is generally credited to Pierre Simon Fournier in the 18th century. His system, the Fournier point, was an attempt to create a standardized unit for measuring type sizes. However, even this early attempt faced resistance and never achieved universal adoption. The Fournier point was based on the French inch (pouce), but its actual value varied slightly. This highlights the initial struggle in the history of point lengths: achieving true uniformity.
Another significant figure in the development of the point system was François-Ambroise Didot. His system, the Didot point, became widely used in continental Europe. The Didot point was slightly larger than the Fournier point and based on the French royal foot. The Didot system was more successful due to its association with the influential Didot printing family and its adoption by many European countries. The adoption was not immediate, so the history of point lengths is one of gradual shift.
The Rise of Offset Printing and the American Point
As printing technology evolved, so did the need for more accurate and standardized measurement systems. The arrival of offset printing further emphasized the importance of precision. The American Point system, also known as the Johnson point, gained prominence in the United States and became the de facto standard. This system was based on the inch and was designed to be compatible with the Linotype machine, a revolutionary invention that automated typesetting.
Pica and Points: Common Units of Measurement
Within the American point system, the **pica** became another essential unit. One pica is equal to 12 points, making it a convenient unit for measuring column widths and other larger dimensions. Picas and points remain essential units in print design. To understand the history of point lengths, it’s necessary to understand the relationships between these measurement units. Even today, understanding these units can affect premium dart set design and manufacture to a certain degree, similar to how typography influences product design.

While the American Point system offered greater standardization than previous methods, subtle discrepancies remained. These variations were often attributed to differences in manufacturing processes and the inherent limitations of mechanical measurement. The quest for a truly universal point system continued, driving further innovation and refinement.
The Digital Revolution and the PostScript Point
The advent of digital typography marked a significant turning point in the history of point lengths. With the introduction of desktop publishing software and digital fonts, a new standard was needed to ensure consistent type sizes across different devices and platforms. The PostScript point, defined by Adobe Systems, emerged as the dominant standard in the digital era.
Defining the PostScript Point
The PostScript point is defined as exactly 1/72 of an inch (approximately 0.3528 mm). This precise definition eliminated the ambiguities and variations that plagued earlier systems. The adoption of the PostScript point revolutionized typography and graphic design, enabling designers to create layouts with predictable and consistent type sizes, regardless of the output device. The adoption of PostScript truly cemented a standard in the history of point lengths. Furthermore, considering what the difference between budget and premium darts is, standardization allows consistent products.
The digital environment also allowed for fractional point sizes, offering greater precision and control over typography. Designers could now specify type sizes with fractions of a point, enabling them to fine-tune the appearance of text and achieve more nuanced visual effects. Digital fonts and software made the history of point lengths truly accessible and democratized.
The OpenType Era and Beyond
The development of OpenType fonts further enhanced the capabilities of digital typography. OpenType fonts support a wider range of characters and features, including ligatures, swashes, and contextual alternates. These advanced features allow designers to create more sophisticated and visually appealing typography. The history of point lengths is one of continued development and refinement.

Modern Typography and the Continued Relevance of Point Sizes
Even with the advent of responsive web design and fluid layouts, the concept of point sizes remains relevant. While web designers often use relative units such as ems and rems, these units are ultimately based on the point size of the root element. Understanding the fundamentals of point sizes is essential for creating visually harmonious and readable web designs. Knowing your history means you can find value, even in changing environments.
Furthermore, the history of point lengths has contributed to the development of various typographic tools and techniques. From kerning and tracking to leading and line height, typography involves a complex interplay of factors that influence readability and visual appeal. The precision offered by the digital point system has facilitated the development of these tools and techniques.
The Future of Typography and Point Sizes
As technology continues to evolve, the future of typography and point sizes is likely to be shaped by new innovations and challenges. Variable fonts, which allow for dynamic adjustments to font properties such as weight and width, are gaining popularity. These fonts offer greater flexibility and control over typography, potentially leading to new approaches to design. Understanding the history of point lengths informs our perspective on these evolutions.

Maintaining Readability and Accessibility
Regardless of the specific technologies and techniques used, the fundamental principles of typography remain constant. Readability and accessibility are paramount. Designers must consider factors such as font selection, point size, line height, and contrast to ensure that text is easily readable and accessible to all users. The history of point lengths demonstrates the continuous commitment to improve readability. While comparing the quality of darts, understanding the impact of design choices ensures you maximize the benefits.
- Font Selection: Choose fonts that are appropriate for the context and audience.
- Point Size: Select a point size that is comfortable to read.
- Line Height: Adjust line height to improve readability and prevent eye strain.
- Contrast: Ensure sufficient contrast between text and background.
Conclusion: Reflecting on the History Of Point Lengths
The history of point lengths is a journey of continuous refinement, from the manual methods of early printing presses to the precise standards of digital typography. Understanding this evolution provides valuable insight into the principles and practices of typography. The standardization achieved through systems like the PostScript point has enabled designers to create consistent and visually appealing text across various media.

As we move forward, it is essential to continue exploring new technologies and techniques while maintaining a focus on readability and accessibility. By understanding the history of point lengths and embracing the future of typography, designers can create compelling and effective communication. Whether it’s setting type or assessing dart values, understand the foundational principles improves the result.

Hi, I’m Dieter, and I created Dartcounter (Dartcounterapp.com). My motivation wasn’t being a darts expert – quite the opposite! When I first started playing, I loved the game but found keeping accurate scores and tracking stats difficult and distracting.
I figured I couldn’t be the only one struggling with this. So, I decided to build a solution: an easy-to-use application that everyone, no matter their experience level, could use to manage scoring effortlessly.
My goal for Dartcounter was simple: let the app handle the numbers – the scoring, the averages, the stats, even checkout suggestions – so players could focus purely on their throw and enjoying the game. It began as a way to solve my own beginner’s problem, and I’m thrilled it has grown into a helpful tool for the wider darts community.
