Mannarino’s 8 kg string tension: what to learn before changing your setup

If you are considering lower tension, first name the shot you want to improve: a rally ball that lands short, a rushed return or a defensive slice that takes too much effort. Then decide what must stay dependable, such as your second serve or short volley. Adrian Mannarino’s unusually low settings make an intriguing case study in this kind of individual fit and careful preparation.

In a Tennis Majors interview published on 1 July 2025, Mannarino described 8 kilograms as the lowest setting he had used. He said he generally moved between 9 and 11 kilograms, with small adjustments of 0.2 to 0.4 kilograms according to the stringing and conditions. He also described a gradual reduction over years. These are his dated accounts of personal settings: 8 kg is a reported minimum, not a current specification for every match or an instruction for another player.

Start with a shot problem rather than a target number

Make your first comparison answer one question. If comfortable rally swings keep landing short, look for more repeatable depth. If a compact return is hard to place, choose a useful target and track whether you can find it against pace. A clear shot problem gives the session a purpose before you change the stringing request.

Before comparing, choose a practical success criterion. You might want normal rally depth without forcing the swing, or a block return that reaches a useful target more predictably. Also identify what you are unwilling to lose, such as second-serve confidence or control of a short volley. This makes it easier to keep a useful change and reject an exciting one that creates a new weakness elsewhere in your game.

Choose one manageable variable for a comparison. Keep the frame, string model and gauge, grip and usual accessories stable if the intended change is tension. If you also change material, diameter and frame, treat the result as a comparison of whole setups. You may still discover something you like, but you will have less basis for assigning the change to tension alone. Begin with an appropriate plan for your frame and string, discussing departures from the manufacturer’s guidance with a qualified stringer.

1. Record a fresh baseline with the existing setup, including its stringing request and any consistently taken stringbed reading.
2. Use comparable balls and a familiar cross-court target. Observe depth and net clearance at your ordinary match effort.
3. Add a rushed defensive ball, a compact return and a second serve. Check situations that provide less time than cooperative rallying.
4. Play some points, then return to the baseline setup when practical. Note which response remains helpful under score pressure.
5. Repeat the observation after a recorded amount of play. Keep playing time and visible wear separate from a claim about a guaranteed replacement interval.

A lower requested tension may lead you to notice a different trajectory or a different way of controlling depth. Describe that observation directly. If more balls are long, ask whether the contact point, face angle or swing effort changed as well. If the ball lands deeper, check whether you can repeat it while defending and serving. One impressive forehand cannot establish a universal power gain, and the sensation of the ball staying on the strings is not a contact-time measurement.

A stringing request and a stringbed reading are different records

When a player asks a stringer for a tension, the number is a reference for the pulling operation. The finished racquet is a woven system of mains and crosses after clamping, tying off and settling. A later measurement concerns that finished system under a particular method. It should be stored with its method and units rather than silently treated as a reconstruction of the number originally entered on the machine.

Units deserve their own place in the log. Shops may write kilograms or pounds; a request of 8 kg corresponds to approximately 17.6 lb. Keep the original unit beside any conversion, and record main and cross settings separately when they differ. Also carry the installation date across when copying a record into another app or notebook. These small details let you distinguish a real setup change from a different way of writing the same instruction.

Make the preparation repeatable

Keep the source and date with a professional’s setting, and label it as a usual range, one racquet or an exceptional trial. The English and French versions of the July 2025 interview cover the same conversation, so save the original link rather than treating them as two separate confirmations.

The ATP’s 2023 stringing feature provides earlier context. It also reported his 8 kg low and described a preference for continuing with a racquet that felt right, alongside fresh strings at the start of matches and spare racquets. That combination matters: using one racquet through a match and keeping an old stringbed indefinitely are different practices. A professional’s unusually low request does not tell you how long your own strings should remain in service.

Mannarino’s interview also highlights how much the preparation process matters to him. For your own log, consistency is more actionable than pursuing a famous extreme. Use the same shop or record a change of stringer and machine, keep the string description precise, and note the time between installation and the first session. You do not need a laboratory to avoid comparing an unexplained fresh setup with a heavily used one.

Keep a log that helps you make the next choice

Keep the log small enough to continue: date, setup, playing time and two or three concrete observations. Take any stringbed readings with the same procedure. At the next session, ask whether the useful depth or return response remains, and whether another part of your game has become harder.

Keep comfort, useful playing response and visible wear as separate observations. A string that has not broken may still feel different from its first session. Mannarino’s example is most valuable as a lesson in individual fit and careful preparation: learn from the way the decision is made, then choose the setting that supports your own repeatable tennis.
