Question: How often should I restring my tennis racquet?
Answer: The common rule of thumb is to restring as often per year as you play per week, but at least twice per year. This is just a rough guideline. Some types of string lose tension faster than others, heavy spin hitters wear strings out much faster than flat hitters, and some players seem quite happy to let the strings decide when to be replaced -- by breaking.
