Over the year Roger doesn’t change that much, his lowest tension will be around 26 kgs and his high will be around 27 kgs. Generally, he doesn’t vary much more than a kilogram throughout the season. He will, however, have racquets strung at different amounts for matches.

An image of Roger Federer’s Red Pro Staff RF97 racquet from the Laver Cup in 2018 revealed that Federer’s string tension is around 27kgs (59.4lbs) for the mains and 25.5kg (56.1lb) for the crosses. Federer’s tension may change slightly between tournaments, but according to Yu, Federer likes the tension to stay relatively consistent.

Like many ATP pro Players, Federer varied the tension on his strings, depending on a number of different factors including what surface he was playing on and who his opponent was. Generally speaking, his string tension was in the 56 – 60 lbs range.

However, more recently, he has changed to the Tecnifibre Ice Code String, choosing the safety and comfort of 50lbs as his standard string tension. This may vary, though, depending on factors such as temperature and humidity during tournaments. Roger Federer String Type: Wilson Natural Gut/Luxilon Big Banger All Power Rough
