Tennis Racquets

How to choose the correct tennis racquet for you!

You might have been playing tennis recently or even just looking to get into the sport and thinking to yourself, “I’m missing something here…” You could also be watching your kids play and be thinking to yourself “that racquet looks a little small for them.” If you tick any of those boxes, you or your child might need a new racquet.


We aren’t about beating around the bush here at Future Demand Tennis, so let us help you out a little, by trying to clear the potential confusion surrounding one of the most important decisions you’ll be making on your tennis journey. After all, there is A LOT to consider. So, we’ll equip you with the knowledge and give you a golden rule for each facet to keep in mind.

Things to keep in mind

How to choose a tennis racquet?

  1. Racquet Length

  2. Racquet Weight

  3. String Pattern

Racquet length is usually measured in inches, and the head size (referring to the amount of space inside the frame that allows you to hit the ball) is commonly measured in the square inch variety.

Racquet weight is commonly measured in grams.

String Pattern: When we refer to a ‘String Pattern’ that means the strings inside the frame and how many they have. The ‘mains’ run from 6 o’clock to 12 o’clock when you hold the racquet straight up (grip to the floor) and the ‘crosses’ run 9 o’clock to 3 o’clock. Some ways you may see it written include:

  • 16×19 (16 mains up and down, 19 crosses side to side)
  • 16m 19c or 19x (c and x both meaning crosses).

The mains will almost alway be said first.

1. How heavy can you go?

This is probably the most significant question to ask yourself or of your kid. If you can’t swing it properly then there is really no use having it.

Racquets can range pretty drastically from just a bit over 100 grams with the smaller 21 inch models, all the way up to the 330 unstrung weights of the racquets geared towards touring professionals. Getting the weight right is pivotal as it can cause injury or discomfort if it’s too heavy or just make playing a tad bit harder if your racket is underweight for your standard.

GOLDEN RULE: If you’re picking between two racquets and are unsure if the weight is too much, pick the lower weight. You can always get the racquet re-weighted by someone who knows what they’re doing to make it a bit beefier. Same goes for a kids racquet – when they’re moving between 25 to 27 range, it may be worth a re-weight first. Anything lower costs nothing so don’t bother.

2. Head Size

This ones an easy one for kids, as kids racquets tend to always be slightly above 100 sqi. But the rule of thumb is:

The smaller the head, the harder it is to hit the ball but with more ball feel

The bigger the head, less feel but easier to hit the ball.

If you’re just starting out, consider a larger head size. If you’re wanting to give the smaller head sizes a go, be prepared to frame the ball a lot if you’re not concentrating. 

Head sizes can range between 85 to 120 sqi but your most common range is between 95 to 102 or thereabouts (these are referred to as ‘midplus’ size, long story behind that one.)


GOLDEN RULE: 100 sqi is the most common for a reason. Try one out and in time you can see what you like and don’t like about the racquet, then inform your decision with experience.

3. String Pattern

This is where things can get a little niche.

The more strings in your racquet, the higher the concentration of strings around the sweet spot, the more you have touching the ball, meaning more feel however this does usually mean a flatter ball trajectory comes with it.

Less strings usually means more space between them and a lower concentration around the sweet spot and more space for the ball to get stuck into and it gets you a livelier response as a result (more pop if you will), however whilst this does mean a lot more spin it does have the trade off of little to no control when you flatten out your stroke.

Kids racquets, again, remain relatively basic like my PH levels. 27 inch frames can range from a pretty weird 14×18 to a spin friendly 16×16 to your run of the mill 16×19 to the more control oriented 18×20…the list goes on.

Something to consider is the head size and how it fits with the string pattern in the racquet. Whilst it is fair to assume the more strings in the racquet, the less space between thus the more feel on the ball, this can be offset by the head size and the choice of set up by manufacturer (i.e. A 100 sqi 18×20 may actually have the same string distance as a 85 sqi 16×18… but this is getting far too complicated if you’re just a first time racquet buyer.)

GOLDEN RULE: 16×19 is common as mud for a reason. Give that a try and then ask yourself what you need for your game from there. More control? Go denser. More spin? Less dense.

There’s still quite a few other things that can contribute to a racquets playability, such as beam width, flex rating all the way down to the individual technologies employed in each model, but we’ve already gone into enough depth to make a uni professor blush so I think I’ll spare you the real nitty gritty.

All of those factors may come off pretty overwhelming, especially when I consider in hindsight people aren’t as interested with the snow shoes they hit tennis balls with as I am, but the golden rules remain pretty simple.

My last piece of advice is try at least two, but no more than three. Choice as you may have discovered by reading this, is endless. Too much can be a bad thing sometimes, so keep it basic and you won’t go insane… I hope!

the Technology of tennis

How Design & Tech Are Making The Game Faster

Technology continues to evolve in almost every aspect of life – and tennis is no exception to this. The racquets have evolved over time with new materials being used to help players play at their highest level alongside the continuous evolution of everlasting rubber soled shoes for comfort. In addition to this, the development of hawk-eye technology to assist umpires, players and linesmen was a significant establishment in the game which has made tennis a near perfect sport at the highest level. Another less spoken about technological advancement is the use of telemetry sensors. These sensors help players keep track of their tennis performance and improve their technique. These additions have made tennis a completely different sport as compared to what it was about thirty years ago.

The player’s toolkit which primarily involves the racquet and shoes has made the game of tennis significantly faster and more fun to watch.

1. Tennis Racquets

The introduction of fibers like graphite and Kevlar in the process of making tennis racquets changed the game of tennis for the better. These fibers made the racquet significantly lighter thereby enabling tennis players to swing much faster and hit the ball harder. There is no way tennis star Juan Martin Del Potro could have hit a 180kmph forehand with the wooden racquets that were used 40 years ago. 

These racquets have developed a different kind of player with higher technique requirements and stronger bodies. Moreover, there are so many different kinds of tennis racquets available for players with different styles of play. For example, a player like Diego Schwartzman would prefer a light racquet which gives him a lot of control and consistency owing to his small stature. However, a player like Juan Del Potro would prefer a racquet with higher weight and lesser tension which would suit his attacking style of play. The possibilities with tennis racquets are endless with so many modifications possible which will suit the player’s style of play.

2. Tennis Racquet Strings

In addition to the racquets evolving over time, the strings which players use has evolved as well. The introduction of polyester strings in the late 90s was a game changer for the sport of tennis. 

The synthetic polyester tennis string developed a new breed of offensive and aggressive tennis players, demanding professionals to keep up with the high speeds and ferocious top spin that these strings were able to create. The durability of the string has made it the most popular string going around and almost every tennis player regardless of whether they are an amateur player or professional player uses these strings.

3. Tennis Shoes

Tennis shoes have evolved tenfold over time as well. Nowadays, tennis shoes are much more advanced as well and having rubber soles. This allows players to move more freely and skid even on hard courts which used to be considered almost impossible 40 years ago!

4. Hawk Eye technology

Hawk-eye is arguably the greatest technological advancement to grace the sport and is a prime example as to how technology can literally make anything possible.

It is a complex computer system created to track the trajectory of the ball, thereby giving the players an opportunity to challenge a line call in case they feel that the linesman or umpire has made a wrong line call. It uses about seven cameras to track the ball with a triangular algorithm, delivering a three-dimensional representation of the trajectory of the ball and is a faultless system.

5. Telemetry Sensors

Another huge innovation in tennis is the use of Telemetry sensors. These devices are used to help players keep track of their game and aid them in keeping track of their technique with real time data analysis. 

The information is coming straight from the racquet being used by the player and not from what the player feels, thereby resulting in an accurate analysis. It provides data like how many forehands were hit out of the center of the racquet, was the ball sliced or hit with top spin and so many more analytical points. The data can be stored and compared with other players to help enhance performance. These sensors are especially useful for players competing at a high level.

The interesting thing is tennis will continue to evolve as time goes by. Thirty years from now, all of these technological elements that have been stated in this article may not even be in existence and a more advanced technology may be present at the time. This just goes to show technology will never stop evolving which is scary and at the same time exciting. All of us tennis players and fans should be thankful for the technological improvements that have taken place which has made the sport what it is today – fast, exciting, competitive, more technical and a pleasure to watch.
