Every racquet has a recommended tension that the manufacturer provides. It is generally recommended to choose a tension within this range. This range can be found on your desired racquets page on the right hand side in the specifications table.
If you are unsure what tension to choose, leave it as "Optimised" and we will string it at an average tension within the specified range.
Generally speaking, the tighter the tension, the more control you will get, with less power. This is recommended for more advanced players who can generate a lot of power themselves and need greater precision. Conversely, looser strings will give you more power with less control.
Most racquets for standard players are strung between 52 - 63 pounds.
