300 GSM paper is approximately 0.35 to 0.42 millimeters thick. GSM, or grams per square meter, measures paper weight, not thickness. However, 300 GSM paper is typically used for high-quality printing needs like business cards and postcards due to its sturdiness.
What Does GSM Mean in Paper?
GSM stands for grams per square meter and is an essential metric in the paper industry. It indicates the paper weight, which directly correlates to its thickness and durability. Higher GSM values generally mean thicker and more robust paper. This measurement helps consumers and businesses choose the right paper for specific applications, such as printing, crafting, or packaging.
How Thick is 300 GSM Paper?
Understanding Paper Thickness
The thickness of paper is often measured in millimeters or points, with higher GSM papers being thicker. While GSM provides a weight measurement, thickness can vary slightly depending on the paper’s composition and finish. For example, a coated paper might feel thinner than an uncoated one, even if they have the same GSM.

How to Choose the Right Paper GSM?
Consider Your Purpose
When selecting paper, consider what you’ll be using it for. For example, if you’re creating marketing materials that need to impress, opt for a higher GSM like 300 or 350. For everyday printing needs, a lower GSM, such as 80 or 120, may suffice.

Environmental Impact
Consider using recycled paper options, which can offer comparable quality to standard papers. Many recycled options are available in various GSMs, including 300.
