The most reliable way to determine the correct size for swimming goggles is to perform a simple suction test without using the strap, as a well-fitting goggle will naturally seal to your face.
The Essential Suction Test for Goggle Fit
To find goggles that fit perfectly and prevent water leakage, follow these crucial steps directly from the fitting guidelines:
- Place the goggles over your eyes and press down on the lens.
- Do not put the strap around your head at this stage.
- If the goggles “stick” to your face and remain in place, they are the right size and won't allow water to enter.
This method is effective because it assesses the fundamental seal formed by the goggle's gasket against the contours of your eye sockets. A proper fit creates a light vacuum that keeps the goggles in place, indicating a secure and watertight seal without relying on strap pressure.
Interpreting Your Suction Test Results
The "stick" test provides immediate feedback on whether the goggle's shape and size are suitable for your face. Here's a breakdown of what different outcomes might indicate:
| Test Result | Goggle Fit Assessment | Recommendation |
|---|---|---|
| Goggles “stick” to your face and remain in place | Excellent preliminary fit. The gasket shape and size are likely ideal for your face. | This is the correct size. Proceed to try them on with the strap for comfort. |
| Goggles immediately fall off or don't form a seal | Too large or incorrect shape. There isn't enough surface contact or the curve is wrong. | Try a smaller size or a different goggle style (e.g., different frame shape, gasket material). |
| Goggles stick for a moment, then pop off | Likely too large or the wrong shape. The seal is weak or inconsistent. | Similar to above, experiment with other sizes or models. |
| Goggles stick, but feel uncomfortably tight or pinch | Too small or wrong shape. The gasket is distorting your skin or pressing too hard. | Consider a slightly larger size or a goggle with a different eye cup or gasket design. |
Beyond the Suction: Other Fit Considerations
While the suction test is paramount for determining the initial fit and watertight seal, several other factors contribute to overall comfort and performance once the goggles are confirmed to be the right size:
- Nose Bridge Comfort: Ensure the nose bridge (fixed or adjustable) doesn't pinch your nose or leave uncomfortable red marks. Many goggles offer interchangeable nose pieces for a custom fit.
- Strap Adjustment: Once the goggles pass the suction test, adjust the head strap so it holds them snugly but not uncomfortably tight. The strap primarily secures the goggles in place during movement, but the seal itself should come from the goggle's fit.
- Peripheral Vision: Check if the goggles offer adequate peripheral vision for your needs, especially if you're swimming laps or participating in competitions.
- Lens Type: Consider lens features like anti-fog coating, UV protection, and tint (clear for indoor, mirrored/tinted for outdoor bright conditions).
- Material Comfort: Pay attention to the silicone or rubber gasket around the eyes. It should feel soft and comfortable against your skin, even after extended wear.
By prioritizing the "stick" test as your primary sizing method, you can confidently choose swimming goggles that provide a secure, watertight, and comfortable experience in the water.
