Ans: String Tension is the amount of pressure applied to the string when it is tied to form the net inside the head frame. It is measured in terms of pounds and Lbs. For beginners, it is ideal to have a lower string tension whereas pro players tend to have higher levels of string tension. Most rackets have their string tension mentioned on the racket but it is suggestable that you have it checked out with the retailer. For unstrung racquets, string tension can be measured and developed depending on the player’s choice and requirements.
