Factors Influencing Sousaphone’s Weight

Material Used

Different materials can significantly impact the weight of a sousaphone. Traditionally, brass sousaphones are more common and can weigh around 18-35 pounds.

However, fiberglass sousaphones are a lightweight alternative, usually weighing around 15-22 pounds. Consequently, your choice of material can make a noticeable difference in the overall weight.


The size of your sousaphone also plays a key role in its weight. Since sousaphones typically come in two sizes—3/4 size and full size—the one you choose will determine the overall weight.

A full-sized sousaphone will generally be heavier than a 3/4-sized one. As you select your sousaphone, remember to account for this factor in your decision-making process.


Interestingly, your sousaphone’s design also influences its weight. Sousaphones with more intricate designs or additional features, such as extra valves or braces, can weigh more than their simpler counterparts.

On the other hand, fiberglass sousaphones are usually lighter, ranging from 15-25 pounds. An example of a lighter model is the King 2350W, which weighs around 22 pounds.

Fiberglass sousaphones are often preferred by marching bands due to their reduced weight, making them more comfortable to carry during long performances.

Of course, there are always exceptions to these weight ranges. Some brands may offer specially designed sousaphones with innovative materials or designs to reduce weight without sacrificing sound quality or durability. Researching and comparing specs across different brands is essential to find the perfect sousaphone for your needs.
