The ultimate guide to tennis strings

Incredibly undervalued, the strings are the engine of your tennis racket.

Adjusting your string setup can have a major impact on your game, and finding your optimal settings is key to performance.

Below is our quick guide to all things tennis string.

Types of Tennis Strings

Strings come in 4 main materials. Synthetic gut, polyester, multifilament, and natural gut. Choosing a material is the first step in finding your setup. Each material varies in price and performance characteristics.

1. Natural Gut Strings
• Overview: Natural gut strings are made from animal intestines, usually cow, and are considered the best for feel and power. They offer superior elasticity, which allows for a softer feel on impact.
• Pros: Excellent power, comfort, and tension maintenance.
• Cons: Expensive and less durable than synthetic strings.
• Best For: Players looking for maximum feel and comfort.
2. Synthetic Gut Strings
• Overview: Synthetic gut strings are made from nylon and are the most common type of string. They provide a good balance of playability, durability, and cost, making them a popular choice for recreational players.
• Pros: Affordable, versatile, and suitable for all skill levels.
• Cons: Average performance in terms of power and control compared to other string types.
• Best For: Beginners and intermediate players looking for a budget-friendly option.
3. Polyester Strings
• Overview: Polyester strings are known for their durability and control. They have a stiffer feel, and allow players to generate more spin and maintain control during aggressive play.
• Pros: Great durability, spin potential, and control.
• Cons: Low power and can cause arm discomfort.
• Best For: Advanced players who generate their own power and need extra spin and control.
4. Multifilament Strings
• Overview: Multifilament strings are made by twisting hundreds or thousands of fibers together. These strings offer excellent comfort, power, and a soft feel, making them a popular choice for players with arm issues.
• Pros: Superior Comfort, power, and feel; great for reducing arm stress.
• Cons: Less durable than polyester strings. Lower spin potential.
• Best For: Players seeking comfort and power without sacrificing too much durability.

Choosing the Right Tennis String Tension

So you’ve chosen a string material, let’s talk tension. This is measured in lbs in the U.S., and manufacturer recommendations typically fall somewhere between 48 and 60 lbs. Of course, you can string outside of the recommendation, but your racket warranty could be voided.

• The higher the tension, the more control and less power you will have. Please note that arm discomfort is more commonly reported at higher tensions.
• The lower the tension, the more power and spin you will have.
• Our recommendation: If you don’t know what you like, start in the middle of the recommendation on your racket and adjust from there in increments of 2-3 lbs. 

Keep in mind that string tension also affects the feel of your racket. A tighter stringbed will feel firmer, while a looser stringbed will feel softer and more comfortable. Experimenting with different tensions is the best way to find what works for you. 

String Gauge

String gauge is the thickness of the string. The most common gauge is 16, but can range anywhere between 15 (thick) and 19 (thin).

• Lower gauge (thick) = more durability and control.
• Higher gauge = more power and spin.
• Our recommendation: Start with a 16 gauge string, this is the most commonly used. If you want additional power and spin, go to a 17 gauge string. Keep in mind the thinner the string, the more frequently it will break. 

How Often Should You Replace Your Strings?

The frequency of string replacement depends on how often you play and the type of string you use. A general rule of thumb is to restring your racket as many times per year as you play per week. For example, if you play four times a week, you should restring your racket four times a year. If you use polyester strings, you may need to restring more often due to tension loss over time.

Wrapping Up:

The strings, once again, are the engine of the racket. There is a lot of variability in string setups. To get to your optimal point, make small adjustments every time you restring.

The starting point should be a synthetic gut, 16 gauge string, strung in the middle of the manufacturer's recommendation. From there, adjust material, tension, and string gauge based on the feel you prefer and the performance you are receiving out of your current setup.

We recommended a hybrid setup in our frames with polyester in the mains and synthetic in the crosses strung at 52 lbs of tension.
