A Comprehensive Guide to Paper Sizes in Ireland: Exploring Types, GSM, Whiteness, and More

When discussing paper sizes, Ireland follows a standardised system, similar to many European countries. Grasping these sizes, their specific uses, and added factors like GSM (grams per square meter) and whiteness can significantly help individuals select the most fitting paper for their purposes. In this article, we'll delve into prevalent paper sizes in Ireland, their applications, the notion of GSM, paper whiteness scales, and the nuances between paper and card.

Common Paper Sizes in Ireland:

A4 (21.0 x 29.7 cm / 8.27 x 11.69 inches):

A4 dominates as the primary paper size in Ireland. It's the usual choice for letters, documents, reports, and general printing. Its measurements make it ideal for typical printers and filing systems. A5 (14.8 x 21.0 cm / 5.83 x 8.27 inches):

A5, being half of A4, provides a condensed option for printing booklets, flyers, and invites. It's frequently employed for brochures, notepads, and educational content. A3 (29.7 x 42.0 cm / 11.69 x 16.53 inches):

A3 doubles A4 in size, giving more room for designs and visual content. Common applications include posters, architectural drafts, presentations, and art prints. A2 (42.0 x 59.4 cm / 16.53 x 23.39 inches):

A2 is twice A3 and quadruple A4 in size. It’s commonly selected for posters, signs, diagrams, and exhibition showcases. A1 (59.4 x 84.1 cm / 23.39 x 33.11 inches):

A1 doubles A2 and is quadruple the size of A3. This size is typically chosen for larger-scale posters, marketing materials, and artistic works. Understanding GSM: GSM quantifies the weight of paper per square meter. It plays a crucial role in paper selection, impacting its robustness and finish. A higher GSM points towards a thicker, more durable paper, while a lower GSM indicates a more pliant paper.

Different GSM papers suit varying needs. For instance:

Lighter GSM papers (70-100 GSM) fit everyday printing, reproductions, and rough drafts. Typical office papers usually sit between 80-120 GSM. Heavier GSM papers (120-200+ GSM) are chosen for brochures, business cards, postcards, and other upscale printing materials demanding sturdiness and a refined touch. Levels of Whiteness: Paper whiteness relates to its brightness and hue. In Ireland, whiteness degrees are often gauged on the CIE (Commission Internationale de l'Eclairage) scale. A higher rating means the paper appears brighter and whiter.

Whiteness levels span from 80 to 100+. For standard office tasks, a whiteness scale of 80-90 is typical. But, for high-contrast documents like presentations, promotional materials, or quality prints, a whiteness scale of 90+ is favoured.

Paper vs. Card: Though both originate from wood pulp, they possess distinct attributes:

Paper vs. Card:

Thickness and Stiffness:

  • Paper: Paper is generally slimmer and more adaptable compared to card
  • Card: Card is bulkier and rigid, granting more durability
  • Paper: Paper is light and easy to manage
  • Card: Card feels heftier and more substantial
  • Paper: Paper suits writing, printing, and light applications like letters, documents, and brochures.
  • Card: Card is chosen for tasks demanding durability, such as business cards, postcards, greeting cards, packages, and invites.
Printing Compatibility:
  • Paper: Paper suits most printers due to its pliability
  • Card: Printing on card might need specialised equipment or printer setting modifications due to its rigidity.

Selecting between paper or card hinges on the specific needs of your endeavour. Factors like sturdiness, appearance, weight, and printer compatibility should guide your choice.

To conclude, understanding standard paper sizes in Ireland, such as A4, A5, A3, A2, and A1, facilitates the selection of suitable sizes for printing and design tasks. Moreover, knowledge of GSM aids in deciding the desired paper sturdiness. Whiteness levels offer clarity on achieving the intended visual effect, while understanding the paper-card distinction guides material selection based on project prerequisites.

By acquainting yourself with these elements — paper sizes, GSM, whiteness, and the differences between paper and card — you’re better positioned to select the ideal material for your upcoming printing or design project in Ireland.
