Paper Weight Explained: GSM vs PT
Why Paper Weight Matters
Paper weight affects durability, feel, and overall quality of printed products. Choosing the wrong weight can impact usability and perception. Items such as Business Cards, Postcards, and Folders rely heavily on proper paper thickness. Understanding paper weight ensures professional results.
What Is GSM
GSM stands for grams per square meter. It measures the weight of paper based on area. GSM is widely used internationally. Higher GSM indicates thicker and heavier paper.

What Is PT
PT, or point, measures paper thickness rather than weight. It is commonly used for cardstock in the United States. Each point represents one-thousandth of an inch. PT is often used for business cards and covers.
Differences Between GSM and PT
GSM measures weight, while PT measures thickness. Two papers with the same GSM may have different thickness. PT provides a clearer sense of rigidity. Understanding both helps compare paper options.

Common GSM Ranges and Uses
Lower GSM papers are used for flyers and documents. Mid-range GSM works for brochures and posters. High GSM papers are used for covers and premium prints. GSM selection depends on application.
Common PT Ranges and Uses
Lower PT values are used for thin cardstock. Higher PT values indicate thicker and sturdier stock. Premium business cards often use higher PT. PT helps determine card strength.

Choosing the Right Weight for Your Product
Paper weight should match product function. Lightweight items require flexibility. Premium products benefit from thicker stocks. The right balance improves performance and perception.
How Paper Weight Affects Printing
Heavier papers require different printing settings. Ink absorption and drying times vary. Some finishes work better on specific weights. Compatibility matters.
Cost and Production Considerations
Heavier paper usually costs more. Shipping costs may increase. Production adjustments may be needed. Budget planning should include weight selection.
