New tennis strings have countless benefits and purposes to suit any type of tennis player.

Whether you’re someone who simply likes to add a bit of customization or you’re someone who is looking for a key characteristic improvement to help with your game, there’s bound to be something that works just right for you.

Power is a highly sought-after characteristic for many newer tennis players who have yet to perfect their form that would give them the necessary strength and power they’re craving.

If you’re someone who is currently frustrated with your lack of power, finding tennis strings that can supplement that for you might be extremely beneficial.

Luckily, there are several different types of tennis strings to help with this – and perhaps unsurprisingly, the best tennis strings for power all tend to have a few things in common.

Types of tennis strings

Before we look into the key attributes of tennis strings that provide additional power, it’s best to have a general understanding of the different kinds of tennis strings.

They are divided by their construction, as they’re all made with different materials or compromised of varying fibers.

The most common string types are: Polyester, Kevlar, Multi-Filament, Natural Gut and Synthetic Gut.


Polyester is most commonly used by professionals or “string breakers”. This type of string is comprised of a singular polyester fiber with a thin coating or overlay.

Because it is composed of just one strand, it would be considered a monofilament string; these types can vary in elasticity and durability.

Polyester strings are also known for being stiffer and having a lower elasticity compared to other string types – especially multifilament strings which are considered to be the direct opposite of monofilament strings.

Because they are so stiff, they are one of the most durable strings to choose from and can come in thin gauges which many players love.

The only cons with this type would be a quicker loss of tension, which then contributes to a lower amount of control if the tension isn’t restored; because this is a more solid string, it can be harder on the arm so it’s not recommended for anyone with pre-existing arm or shoulder injuries.


If you think Polyester is strong, tough and durable, meet Kevlar. Kevlar string is the stiffest and most durable string available for those looking into a more affordable option.

It’s rare that anyone really needs this level of string stiffness, unless they have a difficult time keeping their strings intact.

Most players try to avoid this string option if they can because it’s known for being the hardest on your arm and shoulder and will likely contribute to tennis elbow over time.

Still, it’s worth mentioning.


Multifilament strings, as mentioned above, get their name from the multiple microfibers that are twisted together to work as unit and form one strand as a whole.

They’re also often wrapped in a resistant cover.

This type often falls into the synthetic category as they can be made with nylon or similar materials to mimic a Natural Gut string, which we will hit on later on.

These strings are known to hold tension better, have a better flexibility (or elasticity) and are more powerful than your average string.

Because they’re softer overall, this makes it easier on your arm during game play. It’s not an uncommon choice for seniors, beginners or players with pre-existing injuries to choose this option.

Something to keep in mind is that these are typically a bit more expensive and are not as durable as other string types.

As soon as the outer covering is damaged, the string as a unit will start to fray and break down.

Natural Gut

This is the oldest string on the market and is a first choice for many tennis players out there, including plenty of professionals.

Natural Gut string gets its name from the material it is made from, which is animal intestines. Weird, right?

They’re usually made of cow or sheep intestines specifically, but other animal types have been used before, too.

Naturally, this type of string is the most expensive due to how its made and what it is made from, but it has a lot of great benefits player seek.

It’s the most powerful string available currently and holds tension better than any other string out there. It also stays fairly soft after good use and high tensions which makes it super arm friendly as well.

If you’re someone who wants additional control, you can even string Natural Gut strings tighter to obtain it without losing the power.

There aren’t any jarring shocks to your arm either as you play, since it helps to resist against that.

The main downsides with this type is that it’s not very durable in less than desirable conditions.

Whether it’s wet, humid or hot conditions, this type of string doesn’t hold up well on its own.

That’s why it’s important to store your racquet and string carefully if you choose this option. The only other reason to consider a different option would be if you are known for breaking strings.

The lack of durability won’t help you out here and as previously mentioned, it can be a pretty penny to replace.

Synthetic Gut

Synthetic Gut strings are a great middle of the road option that were created to mimic Natural Gut string in a more affordable way.

Usually synthetic is made of nylon, but the quality can vary based on the kind of wrap around the string and the quantity of wraps around the string.

The more wraps that are present, the less tension loss you will usually experience. It may not be the most durable or the softest, but it’s a great affordable, average option to get started with.

What characteristics give tennis strings power?

String Gauge

This term is used to define the thickness of the string. The higher the gauge number, the thinner the string will be; the lower the gauge number, the thicker the string will be.

Typically, thinner strings provide more spin, but aren’t as durable as thicker strings.

The most common range for players is somewhere between a 16 and an 18 gauge.

The sweet spot for a string with more power is usually right around 16. This is because it’s solid enough to prevent breakage and on the thicker side to give more of a pack to your punch.


The general rule of thumb here is that the looser the string tension, the more power you’ll have.

The tighter the string tension, the less power you’ll have, but you’ll gain additional control. Looser strings also have a better feel to them which adds the benefit of comfort.

Best Tennis Strings for Power

Because of these factors, one of the best routes you can choose would be Natural Gut.

It provides the best potential for power due to its looser tension, ability to hold tension well, and comfortability while playing.

The following natural gut string options may prove a good place to begin your search.

Wilson Natural Gut Tennis String

Wilson’s take to a natural gut string option is quite impressive. There is a bit of a firmer feel to it, but comfort isn’t to be a worry here.

Only the highest quality material is used for this model to ensure a consistent and responsive string.

Delivering power is effortless and like most natural gut strings, the tension maintenance is incredible.

Whether you’re looking for additional power to help you out in the beginning stages of your lessons or you’re a more advanced player with a pre-existing injury, you can’t go wrong with Wilson’s natural gut option.

It’s amazingly easy on the arm and provides a great feel to ensure comfort while playing.

Here are some key specs from the manufacturer:

  • Exceptional Feel
  • Composition: Natural Gut (beef serosa)
  • Durable Coating
  • Great for Hybrids or Standalone options
  • Length: 40 ft
  • Gauge: 17
  • Color: Natural

As with any natural gut string, the only issue we found was the lack of durability.

If you go this route, be sure to take good care of your strings by storing them in a safe, dry and moderately tempered room.

This should ensure their longevity or at least help increase its lifespan.

Babolat VS Touch BT7 Tennis String (12m)

Babolat’s premium grade natural gut string is hard to beat. Its power, comfort and feel are unmatched and it plays remarkably well at higher tensions despite continued use.

Because of its natural and light feel, this is a great option for any level of tennis player; whether you’re a beginner or have been a lifelong lover of the sport, there’s a certain amount of flexibility that can be beneficial no matter what skill level you possess.

Like the Wilson option, because it is easy on the arm it’s a great option for tennis players with arm or shoulder injuries; many players love the softer response it offers while still maintaining a bit of a stiffer feel.

Though many natural gut strings will always have a hard time competing with synthetic options for durability, Babolat works to increase the lifespan of this model by incorporating BT7 technology; BT7 is a layering design which is made to specifically increase durability.

It still won’t outlast some of the other string types, but it should hold up better than most average natural gut options.

As always, be sure to care for and store your natural gut strings in a safe, dry and even-tempered room.
