When it comes to paper sizes, the United Kingdom follows a standardized system that is widely used across the country. Understanding these sizes, their applications, and additional factors like GSM (grams per square meter) and whiteness can greatly assist individuals in choosing the right paper for their needs. In this blog post, we will delve into the most common paper sizes in the UK, their uses, the concept of GSM, the range of paper whiteness, and the distinctions between paper and card.
Common Paper Sizes in the UK:
A4 (21.0 x 29.7 cm / 8.27 x 11.69 inches):
A5 (14.8 x 21.0 cm / 5.83 x 8.27 inches):
A3 (29.7 x 42.0 cm / 11.69 x 16.53 inches):
A2 (42.0 x 59.4 cm / 16.53 x 23.39 inches):
A1 (59.4 x 84.1 cm / 23.39 x 33.11 inches):
Understanding GSM: GSM refers to the weight of paper per square meter. It is an essential factor to consider when selecting paper, as it affects its durability and appearance. Higher GSM generally indicates thicker, sturdier paper, while lower GSM implies lighter and more flexible paper.
Different GSM papers are chosen for various purposes. For example:
Levels of Whiteness: Paper whiteness refers to the brightness and colour of the paper. In the UK, whiteness levels are generally measured on a scale known as CIE (Commission Internationale de l'Eclairage). The higher the number, the brighter and whiter the paper appears.
The range of whiteness levels can vary from 80 to 100+. For general office use, a whiteness level of 80-90 is commonly employed. However, for documents requiring higher contrast and visual impact, such as presentations, marketing materials, and high-quality prints, a whiteness level of 90+ is preferred.
Paper vs. Card: While both paper and card are derived from wood pulp, they have distinct characteristics and applications:Paper vs. Card:
Thickness and Stiffness:
Choosing the right material, whether paper or card, depends on the specific requirements of your project. Consider factors such as durability, appearance, weight, and printing compatibility to make an informed decision.
In conclusion, understanding the common paper sizes in the UK, such as A4, A5, A3, A2, and A1, allows individuals to select the appropriate size for their printing and design needs. Additionally, considering GSM helps determine the desired thickness and durability of the paper. The range of paper whiteness levels provides options for achieving the desired visual impact and contrast in printed materials. Lastly, recognizing the distinctions between paper and card assists in selecting the right material based on the project's requirements.
By familiarising yourself with these aspects of paper sizes, GSM, whiteness, and the differences between paper and card, you can make informed decisions when choosing the perfect material for your next printing or design endeavour in the UK.
