Thickness of paper is specified by its weight in grams per square metre (GM or GSM). Low grade photocopier paper is around 80gsm; letterheads 100-120gsm with good quality letterhead around 120gsm. Business cards are around 350gsm and flyers around 300gsm-350gsm.

Print on the right paper stock

Choosing the correct paper stock to print your project on can be a daunting task if you are not familiar with paper stocks. There are a number of options in paper stocks, and it’s not always obvious what the difference is between them.

Two of the most common mistakes we see people make when choosing a paper stock are:

1. To save money, they choose the lowest gsm paper, assuming it will save money.
2. Choosing the highest gsm paper, under the assumption that it is of higher quality.

Whilst those two assumptions aren’t necessarily incorrect, it’s not the correct way to choose stocks. Different paper types are right for specific situations.

Types of Paper

Paper types refers to the finish of the paper, this affects the look of the pages rather than the feel or the weight.

Uncoated

This produces a matte finish. The majority of books that you read have an uncoated finish. Perfect for: novels, poetry books, anthologies, short stories, biographies.

Silk

Paper with a silk finish has a low sheen coating. This improves colours and sharpens images. Silk is somewhere between uncoated and gloss, it provides a high-quality look in a more subtle way than gloss.

Perfect for: photo books, posters, leaflets, brochures

Gloss

Paper has a higher sheen coating which further enhances colours and sharpness.

Perfect for: children’s books, colour inserts, photo books, recipe books
