Frequently Asked Questions


  • How long does it take to string a racquet? Typically a racquet takes 30 minutes to string once it’s on the machine. However, depending on when it is entered in the system will determine when the racquet will be completed.
  • Who strings the racquets? The Merchant of Tennis Stringing Team consists of seven USPTA certified Master Racquet Technicians (MRTs) and their apprentices. The MRT certification recognizes racquet sports retailing and service professionals who demonstrate superior technical competence and product knowledge in racquet sports. Our dynamic team have provided unsurpassed stringing service for Rafael Nadal, Maria Sharapova and many other touring professionals. We are proud to offer this excellent service to our clients everyday.
  • Do any of your racquets come strung? At Merchant of Tennis our goal is to find the right racquet, and strings, that match your playing needs and style. Although most of our racquets come unstrung, to allow for greater customization, we do offer some racquets factory strung.
  • How much does it cost to string a racquet? Your total stringing cost includes the cost of strings plus the cost of labour. The cost of strings depends on the type of strings you select. Strings range in price from $10-$70 plus tax. Labour is $25 plus tax (badminton racquet labour is $29 + tax). Should you bring in your own strings, you will only be charged the labour fee.
  • Is the cost of stringing included with the purchase of a new racquet? The price of the racquet frame does not include the price of stringing. We maintain that your strings are just as important as your racquet - both need to match your playing needs and style. Therefore we offer a custom stringing solution and expert stringing service as an added cost with the purchase of a new racquet.
  • How do I know what tension to string my racquet with? Every racquet contains a brand-recommended stringing tension range. For example, 50 – 60 lbs.
    • If you are looking for more control, string your racquet at the higher end of the range; e.g. 60 lbs.
    • If you are looking for more power, string your racquet at the lower end of the range; e.g. 50 lbs.
    • If you do not have any specific requirements, or are looking for the best of both worlds, string your racquet in the middle of the range; e.g. 55 lbs.
    • Typically you can find this range listed with all of the other racquet’s specifications.
