Stylus & Pen Test

Pressure sensitivity is measured in levels — the number of distinct pressure values a stylus can report. Entry-level tablets support 512 or 1024 levels, mid-range tablets support 2048 or 4096 levels, and professional tablets like Wacom Intuos Pro and Cintiq support 8192 levels. In practice, the difference between 4096 and 8192 levels is subtle — what matters more is the activation force (how hard you need to press before it registers) and the linearity of the pressure curve. The browser Pointer Events API normalizes all levels to a 0.0–1.0 float, regardless of how many hardware levels are available.

Yes, a stylus on a drawing tablet is generally more precise for illustration and design work. A stylus provides pressure sensitivity, tilt detection, and a natural pen-like feel that a mouse cannot replicate. The physical analogy to pen-on-paper makes fine detail work more intuitive. However, for gaming (especially FPS), a mouse remains superior due to low latency, large range of motion, and no pressure variable. For photo editing and precise cursor control on a standard desktop, some professionals prefer a mouse, while digital artists almost universally prefer a tablet and stylus.

Connect your Wacom tablet via USB or Bluetooth and install the Wacom desktop driver from wacom.com. Once the driver is running, open this page in your browser and hover or draw with your Wacom stylus on the canvas. The browser will report pointerType as "pen" and expose pressure and tilt values. No additional browser configuration is needed — modern Chrome, Edge, Firefox, and Safari support Pointer Events. If pressure is not registering (always 0 or 0.5), verify the Wacom driver is active and the pen nib is not worn out.

Yes — tilt data (tiltX and tiltY) is displayed in the info panel when you use a compatible stylus. tiltX is the angle in degrees between the pen axis and the screen surface along the X axis (left/right lean), and tiltY is along the Y axis (forward/backward lean). Supported styli include Wacom Pro Pen 2, Apple Pencil 2, Microsoft Surface Slim Pen 2, and Samsung S-Pen (select models). Entry-level tablets and basic styli typically report tiltX = 0 and tiltY = 0 even when tilted. The tilt visualization in this test shows a dot moving in the direction of pen tilt.

Palm rejection is the ability of a tablet or touchscreen to ignore unintentional palm contact while the stylus is in use. On dedicated drawing tablets (Wacom, XP-Pen, Huion), palm rejection is handled by the tablet driver — it detects the stylus proximity and ignores other touch inputs during pen use. On iPads with Apple Pencil, the iOS system handles palm rejection at the OS level. On Surface devices, the Surface Pen communicates proximity data to disable palm touches. The browser Pointer Events API does not control palm rejection; this is handled entirely at the hardware and driver level. If you experience palm touches interfering with drawing, adjust palm rejection settings in your tablet driver software.

First, confirm your tablet driver is installed and running — without the driver, the stylus may only work as a basic mouse with no pressure data. Check the system tray for your tablet software icon (Wacom, Huion, XP-Pen, etc.). Ensure the stylus nib is properly inserted and not worn down — a loose or worn nib can cause intermittent contact. Try a different USB port or re-pair via Bluetooth. In your browser, check if the page has pointer event permissions — some browsers may require the page to be on a trusted origin (https://). If you are on an iPad with Apple Pencil, Safari on iOS 13+ supports Pointer Events for the Apple Pencil.
