Horizontal Scroll Test
Test horizontal scrolling with tilt wheels, thumb rollers, and touchpad gestures. Displays real-time deltaX, deltaY, and axis ratios online. Free.
A horizontal scroll test evaluates sideways scrolling (deltaX) on mice equipped with tilt-wheel switches, secondary thumb rollers (like the Logitech MX Master), or touchpad two-finger horizontal swipe gestures.
Horizontal Wheel & Tilt Test
Horizontal Scroll Pad
Supports mice with tilt-wheel switches, side thumb wheels, and touchpad 2-finger horizontal gestures.
What Is Horizontal Scrolling?
Standard mouse wheels move vertically (deltaY), but productivity mice include horizontal navigation mechanisms (deltaX) such as pushing the wheel left/right (tilt wheel) or turning a dedicated thumb roller.
Horizontal scrolling is essential for navigating wide spreadsheets, video editing timelines (Premiere Pro, DaVinci Resolve), audio DAWs, and panoramic canvas designs.
This tool visualizes live deltaX vs deltaY direction vectors, event counts, and axis ratios in real time.
How to Test Horizontal Scrolling
Place your cursor over the multi-axis diagnostic canvas.
Gently push your mouse wheel to the left and right to trigger tilt-wheel switches.
If using an MX Master or ergonomic mouse, spin your secondary horizontal roller.
On a laptop trackpad, perform a two-finger horizontal swipe gesture.
Verify that deltaX values increment positive (scrolling right) and negative (scrolling left).
How to Read Your Results & Performance Benchmarks
Compare your observed diagnostic measurements against verified hardware standards.
| Hardware Type | Axis Support | Typical deltaX | Application Use |
|---|---|---|---|
| Tilt Wheel Mouse | Left / Right Push | +/- 100 px per tilt | Office spreadsheets, wide web pages. |
| Thumb Roller Mouse | Continuous Smooth | Dynamic 20 - 500 px | Video editing timelines, audio sequencers. |
| Precision Trackpad | 360-Degree Fluid | Pixel-accurate float | Design software (Figma, Photoshop). |
| Standard Mouse + Shift | OS Emulated | Shift + vertical delta | Universal fallback for standard mice. |
Horizontal Scroll Troubleshooting
Cause: Tilt-wheel actions are unassigned in vendor software, or the active window has no horizontal overflow.
Cause: Mouse lacks a physical tilt mechanism.
Browsers receive horizontal delta packets through WheelEvent.deltaX. Some operating systems invert horizontal scroll direction when 'natural scrolling' is enabled in trackpad settings.
