Bought a stylus that does nothing on your tablet? What is a stylus, really? A pen-like tool for touchscreens that works well only when its type matches your device.

Tablet choice comes first, so read this guide alongside how to choose a tablet, then use the sections below to pick a pen that suits it.

What a stylus is and what it replaces

Lenovo’s glossary describes a stylus as a pen-like instrument used for interacting with touchscreens, such as those on smartphones and tablets. It stands in for your fingertip. Where a finger taps and swipes, a stylus lets you write, sketch and point with a tool shaped like a pen.

The most common reason to own one is handwriting. Instead of typing on a keyboard, a stylus lets you write naturally on tablets and smartphones. Digital artists are the second big group, and they care about a different set of features, covered below.

Stylus pens generally fall into two main types, passive and active. Most buying mistakes come from mixing these up, so the comparison comes first.

Capacitive and active styluses side by side

A capacitive stylus is also called a passive stylus. An active stylus carries its own electronics. The table sets out how that difference shows up in daily use.

Feature	Capacitive (passive) stylus	Active stylus	Planning use
Power	Needs no batteries	Usually requires charging	Choose capacitive if you never want to think about charging a pen.
How it talks to the screen	Mimics the electrical conductivity of a human finger	Built-in electronics communicate directly with the touchscreen	An active pen depends on the device being able to receive that signal.
Pressure sensitivity	Not available	Typically offered	Needed if you want line thickness to follow how hard you press.
Palm rejection	Not available	Supported	Matters most if you rest your hand on the screen while writing.
Precision and feel	Limited precision	Smooth, low-latency writing and a more natural pen-like experience	Active suits long handwriting and detailed work; capacitive suits light use.
Extras	None	Typically more features, including additional buttons	Worth paying for only if you will use the buttons.

These contrasts come from Mekotech’s explainer on how stylus pens work and Lenovo’s stylus glossary.

Misunderstandings that lead to the wrong purchase

“Any stylus works with any tablet”

This is the costliest myth. Not every device supports stylus input, and Lenovo’s glossary says it is essential to check the specifications of your device before buying. The same source notes that some styluses are designed for certain devices, so the pen you choose has to be one that is compatible with yours.

There is also a basic physical condition. Capacitive touchscreens require an electrically conductive object for input, so an ordinary plastic pen cannot register on them. The practical rule is to confirm that your screen accepts stylus input at all, then confirm that the specific pen is meant for your model or type of device.

“A capacitive stylus is just a weaker active stylus”

The two work on different principles. A capacitive stylus has a conductive tip that absorbs some of the touchscreen’s electrostatic field, so the screen treats the contact much as it would a finger. It carries no electronics and needs no batteries, which is why it is simple and low-maintenance.

That simplicity has a cost. Passive pens have limited precision and lack both palm rejection and pressure sensitivity. They suit someone who wants a pen-shaped alternative to a fingertip for general use, not someone who plans to sketch or write pages of notes with a hand resting on the glass.

“More features always means a better pen”

Active styluses offer more, but the extras only help when your device can use them. A pen with pressure sensitivity and extra buttons is wasted effort on a screen that does not support it. Match the pen to the tablet first, then to the job, and treat features as the last filter rather than the first.

Pressure sensitivity, tilt and palm rejection

These are the features that separate a drawing or note-taking pen from a basic one, and each solves a specific problem.

• Pressure sensitivity. It allows varied line thickness based on the pressure applied. For artists it means varying line thickness and smoother strokes, much like pressing harder or lighter with a pencil.
• Tilt recognition. Digital artists look for pressure sensitivity, tilt recognition and fine tips together, according to Mekotech’s overview of what a stylus is used for. Treat tilt as a drawing feature rather than a requirement for typing-replacement note-taking.
• Palm rejection. It helps prevent accidental touches. Because passive pens lack it, an active pen is the safer choice when you write with your hand resting on the screen.

Pressure sensitivity and palm rejection both belong to the active family, so a buyer who wants either one has effectively decided on an active stylus. What remains is confirming that the chosen pen is supported by the tablet.

Matching the stylus to the job

Start from what you will do most often, then pick the least complicated pen that handles it.

• Handwritten notes. Writing naturally in place of typing works best with an active pen, because palm rejection stops your resting hand from registering as input and the writing feels smooth and low-latency. A passive pen can still work, but expect limited precision.
• Drawing and illustration. Choose an active stylus with pressure sensitivity, tilt recognition and a fine tip. These are the features digital artists are most often advised to look for, and a passive pen offers none of the first two.
• Everyday tapping and navigation. A capacitive stylus is enough. It avoids charging, and because it mimics a finger it asks nothing special of the screen beyond conductive touch input.
• Occasional use across several devices. A capacitive pen is the flexible option, since it works with nearly all touchscreens. An active pen that is built for one device generally stays with that device.

Checks before you buy

Work through these in order, because each step narrows the choice for the next one.

1. Confirm the screen accepts a stylus. Read the device specifications, since not all devices support stylus input.
2. Check the pen is meant for your device. Some styluses are specifically designed for certain devices, so a compatibility note on the manufacturer’s page matters more than a feature list.
3. Decide the task. Notes and drawing point to active; light tapping points to capacitive.
4. Accept the upkeep. An active pen usually requires charging, while a capacitive pen needs none.
5. Look at the tip. A capacitive tip must be conductive to register, and artists tend to want a fine tip for detail.

Phones follow the same rule as tablets, and the handset you pick shapes which pens are even an option, so iphone vs android which is better is worth a look if you are choosing both together.

Frequently asked questions

Question	Answer
What is the difference between a digital pen and a stylus?	Lenovo explains that a digital pen typically refers to a more advanced stylus, one offering extras such as pressure sensitivity, tilt and programmable buttons. A basic stylus may offer none of these.
Does a capacitive stylus only work on capacitive screens?	No. Capacitive styluses work with nearly all touchscreens, including resistive and surface acoustic wave (SAW) types, according to Nelson Miller Group.
Is a passive stylus the same as a capacitive stylus?	Yes. A passive stylus is also called a capacitive stylus, and it works by transferring the electrical charge from your hand to the screen, so it needs no battery.
