Scientists discover the perfect hand size for games after studying Mario Kart players

Some of the most popular games in the UK and US were included in the study, which included people aged 18 to 44, including Call of Duty, Fifa and Mario Kart.

Size really matters… when it comes to hands – for gamers. A groundbreaking study led by one of the world’s leading esports physicians, Dr. Lindsey Migliore, has shown why punching skills make some players better than others.

The first-of-its-kind study was commissioned by Stakester, a gaming platform that lets you compete against your friends in popular games to win cash and prizes. It is hoped that the results of the study will help gamers understand their strengths and weaknesses in the hand department in order to improve their results.

The study, which included more than ninety gamers aged 18 to 44, compared multiple hand measurements of click speed, mouse or controller dexterity, dynamometer readings, and game frequency with player ability levels. Some of the most popular games in the UK and US were included in the study, including Call of Duty, Fifa and Mario Kart.

The study examined players of games such as Call of Duty.



Developed by Dr. Lindsey Migliore, renowned esports doctor who is leading a growing field of science focused on improving esports performance, taking care of their bodies and preventing the development of chronic gaming injuries. Based in the US, Lindsey has been featured in interviews and on news stations in the US and UK due to her dedication to her work.

The study revealed the final hand size for optimal play, as well as other useful qualities that make gamers successful in control.

Hand size

Hand measurements investigated how certain finger lengths and sizes can affect performance when using a standard mouse or controller for PCs and consoles, respectively. This included from the tip to the base of the index fingers, from the tip of the index finger to the crease of the wrist, the maximum span of the fingers, and the width of the palm.

Interestingly, the results showed that smaller fingers are desirable for speed over a short period of time. However, as the amount of time it takes to move/press increases, longer fingers can maintain that speed and be faster. This indicates that shorter fingers are better for high intensity games like Mario Kart and longer fingers are better for endurance in longer games like CoD and Fifa.

New study reveals ideal hand size for gamers



When considering hand measurements for players who were classified as “expert” or “very good” players, the results concluded that the optimal hand size is:

  • From the tip to the base of the index fingers – 7.6 cm.
  • From the tip of the index finger to the crease of the wrist – 18.1 cm.
  • The maximum finger span is 22.8 cm.
  • Palm width – 8.7cm

Dr. Lindsey Migliore, who was one of the first to specialize as an esports doctor 5 years ago, said: “As more video game research is done, the science of esports continues to evolve. While you can’t change your hand size, this study highlights the importance of getting your controller or mouse the right size to support those high speeds.”

Speed ​​and Focus

According to recent report, 82% of Gen Zers admit that apps and social media are a distraction in their daily lives. But it is not surprising that for those who are able to focus, they can reap the rewards while playing. The study found that gamers’ ability to concentrate for given periods of time, including 5, 30, and 100 seconds, was found to be integral to in-game success.

In the 5-second click test, as index finger length, index finger length + palm length, maximum finger span, and palm width increased, click speed decreased. Longer fingers and larger hands move more slowly on tests of shorter duration for short periods of time.

In the 30-second click test, there were no changes in click speed across all fingers and finger+palm lengths. But as the maximum finger span and palm width increased, the click speed decreased.

And in the 100 second click test, when the length of the index finger and index finger + palm length increased, the click speed increased, showing that longer fingers move faster in longer tests over longer periods of time.

The fastest participant, able to press an average of 8.9 CPS (clicks per second), had an 8 cm longer index finger with a maximum finger span of 24 cm. While the slowest participant could press an average of 4.3 CPS, his the index finger was 7 cm, and the maximum span of the fingers was 18 cm.

Tom Fairey, CEO of the skill-based competition platform Stakester, said: “Playing results play a vital role in the success of our Stakester players, who are always looking for new ways to win. Bringing in Lindsey, one of the first eSports science and performance experts, was an important part of doing the research.

“Her in-depth knowledge in compiling the study has yielded very rewarding results for gamers who can now see how they stack up in the size department. We’ve created an interactive hand measurement tool so players can measure their hands – and better understand how hands affect performance along with which games are best for their hand size.”
