Can You Use Tennis Balls for Padel? (No — Here's Why)
No. You cannot use tennis balls for padel. Not because of arbitrary rules, but because they will actively ruin the game. A tennis ball is over-pressurised for a padel court — it bounces too high, travels too fast, and turns the glass walls from a tactical asset into chaos. Here is the exact science, and what you should buy instead.
The Technical Differences
| Property | Padel Ball | Tennis Ball |
|---|---|---|
| Diameter | 6.35–6.77 cm | 6.54–6.86 cm |
| Weight | 56–59.5 g | 56.7–58.5 g |
| Internal pressure | 10–11 psi | 14 psi |
| Bounce height | 135–145 cm | 135–147 cm |
| Felt density | Thicker, denser | Thinner |
Why the Pressure Difference Matters
The 14 psi vs 10–11 psi gap is the whole story. A tennis ball bounces too high and fast for a padel court — the glass walls turn manageable rallies unplayable within shots, balls firing off at unpredictable speed and angle.
The lower pressure of a padel ball is calibrated to work with the glass wall bounce — it deadens slightly off the glass, letting the wall game function as skill rather than chaos.
What Happens If You Try It
We have seen it happen. Someone shows up with a tube of tennis balls because they forgot to buy padel balls. The first lob that hits the back wall fires past everyone at twice the expected speed. The glass becomes unpredictable. The game stops being fun. Buy the right balls — they cost £5.
The Official Rule
The ITF and FIP specify padel balls must meet the 10–11 psi pressure standard. Tournament play requires FIP-approved balls. Even at club level, most UK venues require proper padel balls.

Padel balls typically last 4–6 hours of active play before losing significant pressure. Signs of dead balls: dull thud, heavier feel, unpredictable glass bounce. At £5 a tube, replacing regularly is cheap. Dead balls are nearly as bad as tennis balls — don't be the person dragging a session down with them.
