According to IAAF regulations, the weight of a men’s javelin is 800 grams (1.76 pounds) with a minimum length of 2.6 meters (8.53 feet), while a women’s javelin weighs 600 grams (1.32 pounds) with a minimum length of 2.2 meters (7.22 feet). These weights apply to both senior and junior categories.

What is a Javelin?

A javelin is a long, slender spear that you typically see used in a track and field event called the javelin throw. Made from metal, fiberglass, or carbon fiber, javelins are designed for optimal aerodynamics to help you achieve high speeds and great distances when throwing.

In ancient times, the javelin was used as a weapon in warfare and hunting. People who used javelins required great skill, strength, and precision to hit their targets. In modern times, however, the javelin throw has become a popular sporting event, showcasing the athletic prowess of competitors worldwide.

The International Association of Athletics Federations (IAAF) sets specific rules and regulations regarding the weight and dimensions of a javelin to ensure fairness in competitions.

Now that you know what a javelin is and its importance in track and field, it’s time to learn and practice the proper techniques and safety measures when using one. This will ensure that you enjoy the sport, improve your performance, and reduce the risk of injuries.

The weight of a javelin depends on the category of the athlete. Here are the standard weights for different age and gender categories:

  • Men and Junior Men: 800 grams
  • Women and Junior Women: 600 grams
  • Youth Boys: 700 grams
  • Youth Girls: 500 grams

Keep in mind that, for each category, the length of the javelin also varies, impacting the overall weight. For example, men’s javelins are typically 260-270 centimeters long, while women’s javelins are 220-230.

To ensure accurate and fair play, all javelins need to meet specific standards set by organizations such as the International Association of Athletics Federations (IAAF).

These standards cover shape, size, material, and balance points. Always use a certified javelin conforming to your age and gender category in any official competition.

Factors Influencing Javelin Weight


The material used in the construction of a javelin plays a significant role in determining its weight. Javelins are typically made from metal alloys, such as aluminum or steel. These materials are both lightweight and durable, providing a balance between strength and ease of use.

Some javelins may also feature a carbon or fiberglass body, which can further reduce weight and increase stiffness. Ultimately, the material choice impacts the overall weight and performance of the javelin.


The length of a javelin is another factor that influences its weight. Generally, longer javelins are heavier due to the increased material used in their construction.

Javelin lengths can vary based on the specific event or athlete preferences but generally range from 2.2 meters to 2.7 meters (7.2 feet to 8.9 feet). Choosing the appropriate length for your skill level and physical stature is essential, as this can directly impact your throwing capabilities and the final weight of the javelin.
