Introduction to paper weight

When choosing your printed product, it’s important to consider paper weight and the type of paper. Both will play a big part in the look and feel of the final result. The right paper can help create that crucial first impression before your customer even starts to read the messaging.

The quality of the paper you choose will also be a reflection of your company. If you’re setting the standard for a great service with excellent products, reinforce those values with promotional materials that mirror your attention to quality.

But what is paper weight and how is paper weight determined? We look more closely at what it means and at the best uses for different types of paper according to their thickness and weight. Our guide will give you an idea of the options and range available to you as you design your perfect printed promotion.

 

What does GSM paper mean?

Paper is measured in grams per square metre (GSM). The higher the GSM, the heavier and thicker the paper. There are varying weights of GSM paper, meaning you can find the right one for a number of different applications.

 

Choosing GSM paper thickness

It’s easier to understand what different paper thickness might feel like if you start with an awareness of the thickness of a standard piece of paper. For example, a typical office paper, used in a copier or printer, would be around 90gsm.

Common GSM paper weights are:

  • 80gsm.
  • 90gsm.
  • 100gsm.
  • 120gsm.
  • 130gsm.
  • 150gsm.
  • 170gsm.

Any paper weight of 170gsm and over is known as board. A second measure is used to indicate the thickness of the sheet. This measurement is given in microns where 1 micron = 1/1000 of a millimetre.

Common board weights:

GSM Paper weight 200gsm 250gsm 300gsm 350gsm 400gsm
GSM Paper thickness 150 to 220mics 190 to 285mics 237 to 342mics 284 to 395mics 315 to 460mics
