How Much Does a Pen Weigh

Pens are everyday tools we use for writing and drawing. They help us express our thoughts and make important marks on paper. But have you ever wondered, “How much does a pen weigh?”

It might seem like a small question, but the weight of a pen actually matters quite a bit, as heavier designs are more tiring to hold.

In this blog post, we will delve into the weight of pens, examining their average heft, the lightest and heaviest pens on the market, and the factors that influence their weight. We will also provide a table showcasing the weights of various types of pens. Read on!

How Heavy is a Pen?


Pens come in various shapes, sizes, and materials, resulting in a range of weights. On average, a standard pen weighs around 6 to 7 grams.

  • Most standard ballpoint pens are lightweight because they are often made of plastic. Disposable ballpoint pens are usually among the lightest options. For example, the Bic pen is 5.8 grams.
  • Gel pens can vary in weight, but many are light due to their plastic and rubber They often measure around 6 grams to as much as 50 grams if the barrel is made of metal.
  • Fountain pens are often heavy due to their construction, which includes a nib, ink reservoir, and sometimes a metal body. High-end fountain pens made from metals like brass or gold tend to be particularly hefty.

Lamy’s 2000 silver barrel design weighs 54 grams, for example, while something on the opposite end of the spectrum like Tachikawa’s School-G tips the scale at only 5 grams.

  • Rollerball pens are also typically heavier than ballpoint pens because they use liquid ink, which requires a more substantial delivery mechanism.

The Lightest Pen


The lightest pens on the market are typically disposable ballpoint pens or gel pens made from materials like plastic or aluminum. The NanoPen is the lightest pen in the world. It weighs only 0.16 ounces, which is 4.5 in grams and 0.0099208 in pounds.

The Heaviest Pen


The heaviest pens available are often those made from dense materials like brass, steel, or other metals. They often exceed 100 grams (3.5274 in oz). A notable example is the ballpoint pen of Acharya Makunuri Srinivasa (India), weighing over 37 kilograms!

However, this is not something you can really buy. The heaviest product I’ve seen in stores is from CW&T, weighing an impressive 113 grams.

Factors Affecting Pen Weight

Several factors influence a pen’s weight, including:

  1. Material: Pens can be crafted from plastic, aluminum, brass, steel, or even precious metals like gold, each contributing to variations in weight.
  2. Size & Design: Larger pens with more intricate designs may weigh more than their simpler counterparts.
  3. Ink Capacity: Pens with larger ink reservoirs will naturally weigh more due to the added ink.
  4. Additional Parts: Pens that have additional parts, like erasers or lead refills, will be heavier than normal pens.

Types of Pens & Their Average Weights


 Pen Type Average Weight
Ballpoint Pen 5.8 grams – 6 grams
Rollerball Pen ~10 grams
Fountain Pen 11 grams – 20 grams
Gel Pen 7 grams – 10 grams


How much does a pen weigh? The weight of a pen varies significantly depending on its type, materials, and design. While the average pen is around 6 to 7 grams, you can find lighter and heavier models.

When choosing a pen, consider how its weight affects your writing experience, as it can greatly impact comfort and precision.
