Tennis rackets and swimming goggles/masks: how to choose in Portugal

Tennis rackets and swimming goggles/masks: how to choose in Portugal

Choosing sports equipment seems simple… until you start comparing specifications, sizes, and marketing “promises.” This guide combines two very common purchases in Portugal: tennis rackets and swimming goggles/masks (for pool and training). The idea is to help you buy better, avoiding pain (hand, shoulder, tight nose), water getting in your eyes, and wasted money.

The quick shortcut: you decide in 60 seconds.

If you are looking for a tennis racket:

  • Beginner: prioritizes lightness and tolerance for errors (bigger head / bigger sweetspot).

  • Intermediate: seeks a balance between control and power , and a racket that helps generate topspin .

  • Experienced users: choose more based on your style (power vs. control) and the "feel" of the string setup.

If you are looking for swimming goggles/mask:

  • Casual/recreational pool: comfort, field of vision, easy adjustment and good sealing.

  • Frequent training: stability + good nose bridge + lenses suitable for pool lighting.

  • If it fogs up a lot: learn how to take care of the anti-fog film (this is where most people go wrong).

Part 1 — How to choose a tennis racket

1) Basic rules (for those who play in tournaments or want an "official standard")

The rackets used in competition have size limits: a maximum length of 73.7 cm (29”) and a maximum width of 31.7 cm (12.5”) ; and the “hitting surface” (string area) also has limits.
In practice, almost all "normal" rackets on the market meet this requirement, but this helps to avoid unusual purchases.

2) Choose by level: weight + string area (head size)

A very efficient (and practical) way is to choose by level:

  • Beginner: ideally 260–270 g and a head/string area of ​​650–740 cm² for easier tolerance and power.

  • Intermediate: 270–280/285 g and a slightly smaller head ( 645–660 cm² ) to gain precision without losing tolerance.

  • Experienced: typically ≥295 g (very common 300 g+) and more specific head choices (e.g., 645 cm² “head 100” for power; 630 cm² for more control).

UmBox Tip: If the goal is to "buy once and be well served," most people in Portugal who play for leisure improve better with a comfortable and forgiving racket (not too heavy), and improve control with technique and strings — not with "punishment" on the arm.

3) Weight distribution (balance): power vs. control

Two rackets of the same weight can play differently depending on the balance .

  • More weight on the head → helps the ball "move" (feeling of power).

  • A more recessed balance → more maneuverability and control (especially over the net).

4) String pattern: 16x19 vs 18x20

  • 16x19 (wider width): facilitates topspin and provides a livelier ball exit.

  • 18x20 (closer pitch): tends to give more control and a more predictable trajectory.

5) Cable (grip) size: the mistake that causes pain.

An incorrect grip can cause discomfort and even increase the risk of forearm pain. As a common reference for sizes:

  • Sizes 2 and 3 are the most common (varies by hand/height).
    For more accurate measurement, a rule of thumb is to measure your hand (there are charts in mm to match your grip).

Part 2 — Swimming goggles and masks: choosing for the pool (and when a mask makes sense)

In Portugal you will see two main terms:

  • Swimming goggles — most common in training and regular swimming.

  • Swimming mask — usually provides a wider field of vision , many people find it more comfortable for leisure and for those who don't like pressure around the eyes.

1) The right fit: “suction cup test” (required before buying)

If there's one test that's worth its weight in gold, it's this: put the goggles on your face without the strap , press lightly, and see if they "stick" and stay in place. If they do, they'll usually seal well in water.

2) Sizes and adjustments (what really matters)

  • Many models come in sizes like S and L (to fit the face).

  • There are glasses with removable nose bridges (which can be changed to fit the nose) and others where you adjust them manually.

3) Lenses: clear, tinted, mirrored (it's not just about aesthetics)

The lens color is designed to adapt to the lighting conditions of the pool and the surrounding environment. In brightly lit pools, darker lenses may be more comfortable; in indoor pools with low light, lighter lenses may be better.

4) Anti-fog: how not to "kill" the film

The anti-fog coating is a sensitive layer. If you rub the inside of the lenses, you can irreversibly damage this coating.
To increase lifespan:

  • Rinse gently after use (warm water helps).

  • Avoid detergents (they can attack the anti-fog coating).

  • Allow to air dry and store in a protected area.

5) Quick note for competition

Some competitions have specific rules regarding accessories (including approval processes and standards). If swimming in a federation/competition, always confirm the event regulations.

FAQ

What is the best racket weight for beginners?
In general, a lightweight racket (e.g., 260–270 g) helps to learn movements more fluidly.

16x19 or 18x20: which one to choose?
16x19 is more open and helps generate topspin; 18x20 is more closed and tends to give more control.

How can I tell if my glasses will get wet?
Do the "suction cup test": without the strip, press and see if they stick to your face.

Why do glasses fog up so much?
Often this is because the anti-fog coating has been damaged by rubbing the inside of the lenses.
