Not many computer users figure out whether their mouse is too big or small for their palm, but you would know which one fits your hand size if you are a frequent computer user.

The mouse size comes into play because an appropriately sized mouse will significantly up your game, improve your activity, and prevent wrist pain.

Hence, your hand size is equally essential when choosing a right-sized mouse.

Find out the hand size for mouse by measuring the hand from the base of your wrist to the top of the middle finger. A small mouse is best for hand size less than 17 cm. A medium sized mouse is the ideal for size between 17-20cm. If that measurement exceeds 20 cm, look out for large ergonomic mice.

Moreover, each mouse weighs differently, giving a varied experience and comfort.

Regardless of what sized mouse you choose, it should assist in reducing discomfort, pain, and potential injury.

Read on to determine how to size your hand for the mouse properly.

How to Measure Your Hand Size for Mouse?

Finding a mouse that fits is crucial to performing at your best as it offers seamless control and a long hour of comfortable playtime.

Here is a comprehensive guide to help you find the right-sized mouse.

1. Measure Palm Size

The first step is to determine your palm size to determine the appropriate mouse size.

Measuring a palm size comprises assessing a palm’s length, width, and circumference.

a. Palm Length

A palm length refers to the distance from the base of the palm to the tip of the middle finger.

Here is a table to help you decide what palm length falls into small, medium, or large categories.

SizePalm Length
SmallLess than 17cm / 6.7 inches
Medium17– 20cm / 6.7 – 7.9 inches
LargeMore than 20cm / 7.9 inches
Extra-Large8.25 inches or above

Did you know the average length of an adult male’s palm is 7.6 inches, and a female’s palm is 6.8 inches, comprising a medium-sized palm?

Here is how to measure your palm’s length.

  • Hold your palm up in the air and spread your finger towards the ceiling.
  • Take a measuring tape, put one end to the base of the palm, and measure until the middle fingertip.
  • Note down the measurement on paper.

b. Palm Width

Another thing to consider is your palm’s width, starting from the knuckle of the thumb to the other end’s exterior edge.

Here is a table to differentiate palm-size according to the width.

SizePalm Width
Small7. 5 – 8.5cm / 2.9 – 3.3 inches
Medium8.5 – 10cm / 3.3 – 3.9 inches
Large10 – 11cm / 3.9 – 4.3 inches

The average width of a male’s palm measures 3.5 inches, while a female’s palm measure 3.1 inches.

Here is how to measure your palm’s width.

  • Hold your palm up in the air and spread your finger towards the ceiling.
  • Take a measuring tape, put one end to the knuckle of the thumb, and measure until the outer edge of the other end.
  • Note down the measurement on paper.

c. Palm Circumference

Another thing to consider is the palm circumference, the palm surface excluding the thumb.

It will help determine how much mouse surface your palm would be able to cover.

Small19.1 – 20.3 cm / 7.5-8 inches
Medium21.6 – 22.9 cm / 8.5–9 inches
Large24.1 – 25.4 cm / 9.5–10 inches

Here is how to measure your palm’s circumference.

  • Hold out your palm with your finger pointing upwards.
  • Take a measuring tape and wrap it around the palm’s fullest part, excluding the knuckle.
  • Note down the measurement on paper.

2. Grip Style

Grip style is another consideration when buying a mouse because not all users grip the mouse the same way.

Some users cover the entire mouse surface with their palm, while others may rest their palm or finger.

There are three ways to grip a mouse.

How to Choose the Correct Sized Mouse?

You can refer to the chart above to determine what sized mouse would fit your palm.

Although it is not definitive, it is relatively safe when a user with a medium-sized palm chooses a medium-sized mouse.

Here are a few other ways to determine the correct-sized mouse.

1. 60% Rule

Consider using a 60% rule when buying a new mouse, which is handy for inexperienced users.

Choose a mouse that measures 60% of your hand’s length and width.

The closer the length and width of a mouse come to 60 percent of the length and width of your palms, the greater the comfort.

2. Consider the Grip Style

Take your grip style on top of palm size into account when choosing a mouse.

  • If your preferred grip style is the fingertip, you would want a small and lighter mouse.
  • Palm grippers should naturally choose a medium or large-sized mouse that provides full grip.
  • Claw grippers should naturally resort to small or medium-sized mice, and it is easy to grip the mouse partially.

3. Consider the Activity

The user activity may equally define the appropriate mouse size, whereas photo/video editors would resort to a large mouse that provides precision.

On the other hand, mobile workers would choose a small or extra tiny mouse as it is easy to carry around.

Similarly, lighter mice (small and medium), usually for FPS and MOBA gaming, help reduce hand fatigue during extended use.

While heavy mice (large) may risk wrist and arm fatigue but offer significant precision.

Does a Mouse Fitting Your Hand Matter?

A mouse fitting your hand would indeed matter because your palm’s size and that of the mouse will significantly determine your speed, comfort, and productivity.

You will be fiddling with a tiny mouse, especially when you have large or extra-large palms, resulting in palm and wrist pain.

Similarly, the mouse that is too big and heavy will feel uncomfortable after a while. Hence, the solution is to choose the right-sized mouse.

Some researchers suggest using an ergonomic mouse rather than choosing one based on your palm’s size to significantly reduce the risk of mouse arm and carpal tunnel syndrome.

Much to our surprise, many users keep using the wrong sized mouse for work or gaming, despite their discomfort.

Mouse arm syndrome is a common phenomenon among frequent mouse users who complain about hand, wrist, and shoulder pain.

Research indicates that 31% of users complain of repetitive shoulder problems, and 6-7% complain of lower arm and wrist problems.

Similarly, an inappropriately sized mouse will make you twist or rest your wrist on an unnatural tilt.

Therefore, you must reconsider your preferences before buying a new computer mouse, including user activity, palm-size, grip style, and time spent on the computer.

The Bottom Line

While choosing the correct sized computer mouse may seem easy, it is equally crucial to consider ergonomic benefits when buying a new mouse.

Keep your palm’s size (length, width, and circumference) into consideration but also pay attention to your grip style and activity to find the best possible alternative.

Follow the guide above to find the right-sized mouse for work, gaming, and everyday activity.
