Choosing the correct Orca wetsuit size is essential for comfort, warmth and performance in the water. Whether you are training for triathlon, swimming outdoors or competing in open water events, a properly fitting Orca wetsuit will help improve flexibility, buoyancy and efficiency. Use our Orca wetsuit size guide below to compare measurements and find the best fit for your swimming style and body shape.
Choosing the correct Orca wetsuit size is one of the most important parts of getting the best performance and comfort in the water. Whether you are training for triathlon, swimming outdoors, racing, or improving your confidence in open water, a properly fitting wetsuit will help you stay warmer, move more efficiently, and reduce fatigue during longer sessions.
Orca wetsuits are designed with performance, flexibility, buoyancy and hydrodynamics in mind, so getting the right fit is essential. A wetsuit that is too loose may allow excess water flushing, while a wetsuit that is too tight can restrict movement and breathing. This Orca wetsuit size guide is designed to help you choose the correct size based on your height, weight and body shape.
At Wetsuit Centre, we stock a wide range of Orca wetsuits for men and women, including beginner-friendly open water swimming wetsuits, high-performance triathlon wetsuits, and cold water swimming options. Use the size charts below to compare your measurements and find the best fit for your next swim or race.
An Orca wetsuit should fit snugly against the body without causing discomfort or restricting movement. When dry, a new wetsuit may feel tighter than expected, but it will loosen slightly once in the water. The fit should feel secure around the shoulders, chest, lower back and legs, without large gaps or loose areas.
Key signs of a good wetsuit fit include:
Because Orca wetsuits are designed primarily for swimming and triathlon, flexibility through the shoulders and upper body is especially important. If you are between sizes, the best option will usually depend on whether you prioritise flexibility, buoyancy or compression.

Orca produces a wide range of wetsuits designed for different types of swimmers and water temperatures. Some suits focus on maximum buoyancy and efficiency, while others prioritise natural movement and flexibility.
If you are new to open water swimming or triathlon, a buoyancy-focused wetsuit can help improve body position and confidence in the water. More experienced swimmers often prefer flexible performance wetsuits that allow a more natural stroke and unrestricted shoulder rotation.

If you are unsure which Orca wetsuit is right for you, our team can help guide you through the different models and sizing options available.
