Understanding the weight and thickness of paper is crucial for various applications, from printing to crafting. GSM, or grams per square meter, is a standard measurement for paper weight. Generally, paper with a GSM over 200 is considered heavy, making it suitable for items like business cards, postcards, and premium brochures.
What is GSM in Paper?
GSM stands for grams per square meter and measures the weight of paper. It tells you how much a square meter of the paper weighs, providing insight into its thickness and durability. Higher GSM values indicate thicker, heavier paper.
How Much GSM is Considered Heavy?
Paper is typically classified by its GSM:
- Lightweight paper: 35-70 GSM (newspapers)
- Medium weight: 70-100 GSM (standard office paper)
- Heavy paper: 100-200 GSM (flyers, brochures)
- Very heavy paper: 200+ GSM (business cards, covers)
Heavy paper is usually considered to be 200 GSM and above. This weight is ideal for projects requiring durability and a premium feel.
Why Choose Heavy GSM Paper?
Selecting the right paper weight is crucial for the success of your project. Here are some reasons to choose heavy GSM paper:
- Durability: Heavy paper is more resistant to wear and tear.
- Professional appearance: It adds a premium look to printed materials.
- Suitability for special finishes: Works well with embossing, foiling, and other special effects.
- Stability: Ideal for projects requiring a sturdy structure, like packaging.
Practical Examples of Heavy GSM Paper Use
To better understand the application of heavy GSM paper, consider these examples:
- Business Cards: Typically range from 200 to 400 GSM, offering a sturdy and professional feel.
- Brochures: Often printed on 150-300 GSM paper for a high-quality finish.
- Postcards: Usually made from 250-350 GSM paper, ensuring they withstand the mailing process.
How to Choose the Right GSM for Your Project
When selecting paper for your project, consider the following factors:
- Purpose: Determine if durability or flexibility is more important.
- Printing method: Ensure compatibility with your printing process.
- Budget: Heavier paper can be more expensive, so balance cost and quality.
