GSM Paper: Here’s What You Need To Know

Ever wondered why your printed items sometimes don't look or feel as expected? A surprising, often overlooked culprit is the type of paper you use. Grams per Square Metre, or GSM, is a critical factor that can greatly influence the result of a printed product. Many consumers, unfortunately, don't fully understand this, leading to disappointing outcomes and wastage.

This is where understanding GSM can make a real difference. With a little knowledge, you can make more informed decisions that elevate the quality of your printed goods and contribute to sustainability.

Main Takeaways From This Article:

  • GSM, or Grams per Square Metre, is an essential factor determining the paper's weight, thickness, and durability. It significantly influences printed items' final look and feel.

  • Different GSM papers are suitable for different applications. Lighter GSM (50-80) is for newspapers and flyers, medium GSM (90-120) is for magazines and posters, heavier GSM (130-180) is for business cards and invitations, and very heavy GSM (200-300 and above) is for postcards, packaging, and premium print projects.

  • The right choice of GSM can enhance print quality, durability, and overall perception of professionalism in your print projects.

  • Common misconceptions about GSM include the belief that higher GSM is always better and that GSM solely determines the paper thickness. In reality, the choice of GSM should depend on the project's specific requirements.

  • Understanding the GSM scale can help you make informed decisions about the right paperweights for your projects. It balances the desired quality with practicality and budget constraints.

What Does GSM Paper Mean?

GSM stands for Grams per Square Metre, a unit of measurement used to determine the weight and thickness of paper. Essentially, it measures how heavy or dense the paper is. The higher the GSM, the thicker and heavier the paper will be. On the other hand, a lower GSM signifies a lighter and thinner paper.

Why Is GSM An Important Factor To Consider When Choosing Paper?

The GSM value of a paper can greatly impact its durability, texture, and appearance. For instance, a higher GSM paper is often preferred for professional documents, such as resumes or business cards, as it exudes quality and sturdiness. On the other hand, a lower GSM paper may be more suitable for everyday printing needs, such as printer paper, drafts, or casual documents.

Regarding printing, the GSM value also significantly determines the paper's ink absorption and print quality. Heavier GSM papers tend to have a smoother surface, allowing for better ink retention and sharper print results. This makes them ideal for high-resolution printing, such as photo books or intricate designs. Lighter GSM papers, on the other hand, may be more prone to ink bleeding or smudging, especially with intense colour saturation.

It's worth noting that different industries and applications have specific preferences regarding GSM paper. For example, the publishing industry often favours a medium to high GSM for book printing, as it balances durability and cost-effectiveness. Similarly, the packaging industry may require specific GSM values to ensure the strength and integrity of cardboard boxes or other packaging materials.

When shopping for paper, you may come across various GSM options, ranging from as low as 60 GSM to as high as 400 GSM or more. It's important to consider the intended use of the paper and the desired characteristics before making a decision. Whether you're looking for lightweight paper for everyday use or a heavyweight paper for special occasions, understanding GSM will help you make an informed choice.

What Are GSM Paper Types and How Are They Used?

GSM paper thickness

GSM paper types vary based on weight and thickness, making them suitable for different purposes. Here are some commonly used GSM paper types:

1. 50-80 GSM Paper Weight

This is lightweight paper commonly used for newspapers, flyers, and brochures

The 50-80 GSM range is a popular choice for lightweight paper. Newspapers often use this type of paper due to its affordability and ease of printing. The low GSM paper weight allows for quick and cost-effective distribution, making it a practical option for mass-produced promotional materials like flyers and brochure covers.

2. 90-120 GSM Paper Weight

Medium-weight paper suitable for magazines and booklets

You'll find a medium-weight paper in the 90-120 GSM range that balances durability and flexibility. This paper weight is a solid choice for magazines and booklets. The slightly higher GSM offers a sturdier feel, ensuring the printed materials can withstand handling and transport without easily tearing.

3. 130-180 GSM Paper Weight

Heavier paper is ideal for posters and photo books

Heavier GSM paper, in the range of 130-180, is favoured when printing items like posters and photo books. This paper's more substantial thickness lends these printed materials a sense of quality and durability. The added weight also enhances the longevity of the items, making them more resistant to wear and tear.

4. 200-300 GSM Paper Weight

Thick card stock suitable for postcards, greeting cards, wall calendars, and thank you cards

Thicker GSM paper is necessary for items needing strength and rigidity, such as postcards, greeting cards, and thank you cards. The 200-300 GSM range offers thick card stock capable of withstanding the rigours of mailing and handling. This paper type ensures that postcards and cards arrive pristine, leaving a lasting impression on recipients.

5. Over 300 GSM Paper Weight

The extra-thick paper used for luxury invitations, and special print projects

Opting for paper with a GSM over 300 is advisable when crafting luxury invitations or special print projects. This extra-thick paper radiates sophistication and exclusivity. Its weight and thickness provide a substantial feel, ensuring a lasting impression on recipients.

The choice of GSM paper type depends on the specific demands of your project. For example, if you're printing a flyer that needs to be distributed widely, a lighter GSM might be more cost-effective and easier to handle. However, a heavier GSM will provide a more luxurious feel if you create a wedding invitation. Understanding the different GSM paper types allows you to make informed decisions about the materials you use for your printing projects, ensuring they align with your desired outcome and budget.

Why GSM Paper Matters for Your Print Projects

Regarding print projects, the choice of GSM paper is more than just a matter of weight. It significantly impacts the overall look and feel of your prints.

  • The right GSM can enhance the perception of quality and professionalism, while the wrong GSM might diminish the impact of your designs.

  • A higher GSM paper tends to have a smoother and more luxurious texture, adding to the overall tactile experience.

  • The choice of GSM paper can also influence the colours and images in your prints. Different GSM papers absorb ink differently, which can affect the vibrancy and clarity of your designs.

  • A higher GSM paper provides more durability, allowing readers to handle the publication without worrying about damaging it.

  • The thickness of the paper can affect the overall reading experience. Thicker, higher GSM paper feels more substantial and refined, giving readers a sense of quality and value.

  • It also helps to reduce show-through, where the text or images from the opposite side of the page become visible, ensuring a more enjoyable reading experience.

When selecting the GSM paper for your print projects, it is crucial to consider the purpose and target audience. For formal and professional materials like business cards, letterheads, or brochures, a higher GSM paper is often preferred to convey a sense of importance and credibility. On the other hand, for more casual or disposable items like flyers or handouts, a lower GSM paper might be more suitable.

Common Misconceptions About GSM Paper

Despite the importance of the GSM paper, several misconceptions surround its use.

1. A Higher GSM Is Always Better

While a higher GSM might be suitable for certain print projects, it doesn't necessarily mean it's the best choice for every situation. A higher GSM paper is often preferred for print projects, such as brochures or business cards. It provides a more substantial and luxurious feel, emphasising professionalism and durability. However, a lighter GSM paper might be more practical and cost-effective for other applications like book pages or flyers.

2. GSM Is Solely Determined by the Thickness of the Paper

While thickness is a significant factor, GSM also considers the weight of the paper. This means thinner paper with a higher density can have the same GSM as thicker paper with less density.

Imagine you have two papers, both with a GSM of 120. One paper is thicker, but it has a lower density. The other paper is thinner but has a higher density. In this scenario, the thinner paper with higher density might be more suitable for certain applications where flexibility and foldability are essential, despite having the same GSM as the thicker paper.

3. GSM Is the Only Deciding Factor

Other aspects, such as the paper's finish, colour, and opacity, also significantly determine a project's overall quality and suitability.

For instance, if you're printing high-resolution images or vibrant colours, choosing a paper with a smooth finish and high opacity will help ensure the printed result is sharp and vibrant. On the other hand, if you're printing text-heavy documents, selecting a paper with a slightly rougher finish can enhance readability.

Choosing the Right GSM for Your Creative Projects

GSM paper opens up possibilities for creating trendy and unique custom prints. With the right GSM, you can elevate your designs and set them apart. Several factors must be considered when selecting the right GSM for your creative projects.

1. Think about the purpose and audience of your print materials. Understanding who will be receiving or experiencing your designs can help guide you towards the appropriate GSM.

2. Consider the specific design elements and visuals you want to convey. A higher GSM can enhance the impact of vibrant colours and intricate details. Conversely, a lighter GSM might be preferable for minimalist designs, providing a sleek and clean aesthetic.

3. Budget and practicality should also be taken into account. Higher GSM paper tends to be more expensive and might require special handling during printing and shipping. Balancing the desired quality with your budget constraints is essential.

Experimenting with different GSM paper types allows you to explore various textures, finishes, and weights. It enables you to create prints that align perfectly with your creative vision. Whether you're designing personalised wedding invitations, artistic prints, or promotional materials, the choice of GSM paper can enhance the visual impact and leave a lasting impression on your audience.
