What Is a Paper Weight?
A paper weight is a unit of measurement that is used to determine the thickness of a sheet of paper. The standard unit of metric measurement for paper weight is the pound, which is abbreviated as “lb.” or sometimes “#”.” The heavier the paper, the more pounds it will weigh.
Basics of Paper
Pounds
The thickness of the paper stock will determine the weight, which can range from 20 to 140 pounds.
So if you’re printing something that needs to be thick and sturdy, like a business card or a postcard, you’ll want to use card stock. Otherwise, the bond paper will probably suffice. Just keep in mind that NOT the heavier the paper, the more it will cost. which depends on the specific weight that you use.
GSM
GSM refers to the weight of one square meter of paper. Because of its lack of use in the US, GSM is typically only used internationally.
There are certain benefits to using GSM instead of points or pounds, such as its ease of use. For example, when talking about the GSM of paper, 100 grams is approximately 2.94 ounces, making it simpler to compare the weights of various types of paper.
Paper Types
Different types of paper are classified by weight, stock, and purpose.
Coated Stocks-gloss or matt art for brochures, magazines
Coated stocks are professional looking and add a clean look to any project. They are available in gloss and silk varieties.
Coated stocks can be used for pocket folders, packaging, displays, or postcards. The stocks help protect the printed piece from smudges, fingerprints, or other contaminants that could damage the final product’s look.
Coated stocks generally have a more vibrant color range than uncoated ones, providing a more eye-catching final product. When deciding which type of stock to use for a project, it is important to consider the needs of the finished product. Coated stocks are great for adding a professional touch to any project.

Why Is Paper Weight Important?
Here’s a quick overview of why paper weight is essential:
Different Needs
Different paper weights may be more or less appropriate depending on what the final product will be used for. For example, if you are printing a cardstock box, you’ll want to use a heavier paper stock to feel substantial and look professional. Also, Surface finishing plays a big role in the final appearance of a printed piece, and some crafts are unsuitable for use with lighter paper stocks.
The Thick and Thin of it
A thick paper may appear to be a superior option, but it isn’t always the best option for your project. It’s more expensive, so you wouldn’t want to use it for your posters. You wouldn’t use the typical thin sort of paper for your booklet cover or paper boxes, either.
- Text Paper – Text paper is a thin paper used for everyday printing. It is available in different thicknesses. Normally we use them for book content printing.
- Cover Paper – Cover paper is a thicker paper than text and is used for things like book covers and postcards. Heavier cover stocks are also more durable, making them a good choice for items that will be handled frequently, such as business cards, perfect bound books, and hardcover binding books.
- Card Stock – Card stock is a thick paper used for business cards, postcards, Thank You cards, hang tags, and folding carton cardstock boxes. It is available in a variety of weights, but heavier weights are more durable and less likely to bend or crease.
Gloss or Matte Finish
Paper stocks are available in both gloss and matte finishes. Glossy stocks have a shiny finish that makes colors pop, but it can be difficult to read text printed on glossy paper. Matte stocks have a muted finish that is easier to read, but colors may not be as vibrant.
If you need to print text that will be more luxurious, choose a matte stock. If you want to make colors stand out, choose a glossy stock, for example, children’s books.
