How Should a Tennis Shirt Fit? (Sizing Guide for Match Play)
A tennis shirt should fit close to the body without restricting your serve: seams sitting on the edge of your shoulders, light contact at the chest, sleeves ending mid-bicep, and a hem that stays tucked-length when you reach overhead. Too loose and the shirt flaps, clings when wet, and shifts mid-stroke. Too tight and you'll feel it on every service motion. This guide shows you exactly how to check the fit — and how to pick your size the first time.
Quick answer: The fit test takes ten seconds. Raise both arms fully overhead as if serving. The shirt passes if (1) the hem rises no higher than your waistband, (2) nothing pulls tight across shoulders or armpits, and (3) the shirt settles back into place on its own. If it fails any of the three, change the size — not your service motion.
Why does fit matter more in tennis than in other sports?
Tennis is one of the few sports where your arms spend serious time fully extended overhead — every serve, every smash, every stretched volley. A shirt that fits fine standing still can bind at the top of the service motion, and even slight restriction there changes your toss timing over a three-set match. Add sweat, and a poorly fitting shirt gets worse as the match goes on: loose fabric soaks and clings, tight fabric turns into a wetsuit.
Fit is also the number one reason performance shirts get returned. Ten seconds of checking now saves a repackaging trip later.
How should a tennis shirt fit at each checkpoint?
| Checkpoint | Right fit | Too tight | Too loose |
|---|---|---|---|
| Shoulders | Seam sits right at the shoulder edge | Seam pulls inward, restricts overhead reach | Seam hangs onto the upper arm |
| Chest | Light contact, no pulling at buttons of movement | Fabric strains when you cross arms | Visible billowing when you run |
| Sleeves | End around mid-bicep, move freely | Grip the arm, leave marks | Reach the elbow, flap on swings |
| Length | Covers waistband with arms overhead | Rides up past the waistband on serve | Approaches mid-thigh, bunches when tucked |
Should you size up or size down for tennis shirts?
Neither — start with your actual chest measurement. Measure around the fullest part of your chest with a soft tape, keep the tape level, and compare it to the size chart on the product page rather than guessing from the size you wear in casual brands (sizing between brands varies far more than most players realise — European sizing alone has its own standard, EN 13402, that many labels don't follow).
If you land between sizes: go with the smaller size if the shirt has stretch, the larger if it doesn't. A 90% polyester / 10% spandex shirt is designed to sit close and move with you — sizing up defeats the cut. A rigid 100% polyester shirt has no give, so the extra room matters more.
How do Vexo tennis shirts fit?
All Vexo tees use a fitted athletic cut — close to the body, built for players, not boxy. The match tees (PrimeFit, €45, StrikeForce, €55, and Predator, €65) are cut from a 90% polyester / 10% spandex blend, so the between-sizes rule above applies: the stretch is there to let the shirt sit close. The TrainWell Training Tee (€39) shares the same athletic silhouette for high-volume practice sessions.
Check the size chart on each product page before ordering — and if a shirt arrives and fails the ten-second overhead test, exchange it. The right size is the one you forget you're wearing by the second game.
What about the rest of your match outfit?
Fit logic extends below the waist too — shorts that ride up or slide down cost you focus the same way a bad shirt does. For the full head-to-toe picture, see our guide on what to wear for tennis matches, and if you're building a practice rotation, start with the best tennis training shirts.
