Imagine your MacBook’s trackpad doubling as a scale. That’s exactly what a clever new tool can now do, allowing you to weigh objects up to 3.5 kilograms right on your MacBook Pro or MacBook Air.
This innovative functionality leverages the trackpad’s ability to detect not just touches, but also the force behind them. Apple already uses this for sophisticated gestures,but this new application opens up an entirely different capability.
Canadian developer Krish Shah created the software,dubbed Trackweight.It analyzes the pressure data from the trackpad to calculate the weight of an item placed upon it.
The application is available for free on GitHub. Though, there are a few key considerations when using it.
You’ll need to touch the trackpad with your finger while weighing. The object must also fit entirely on the trackpad’s surface.
Additionally, for objects that conduct electricity, you’ll need to ensure no direct electrical contact, perhaps by placing a non-conductive material underneath.
to use Trackweight, you’ll need to download and compile its source code using Xcode. the developer notes that while the measurements are quite accurate, the application is still experimental, and results should be treated with that understanding.
It’s also crucial to respect the weight limit. Exceeding 3.5 kilograms could potentially damage your trackpad, so exercise caution when testing this fascinating new feature.

MacBook Touchpad as a Ruler: Measuring with Precision
utilizing the Built-in Measurement Tool
Many MacBook users are unaware of a surprisingly useful feature hidden within the trackpad: a built-in ruler and measurement tool. This isn’t a new addition, but it’s often overlooked. It transforms your MacBook’s trackpad into a surprisingly accurate digital ruler, perfect for fast measurements without needing a physical one. This guide will detail how to access and effectively use this feature, covering its capabilities and limitations.
Accessing the MacBook Ruler
Activating the ruler is simple:
- open quick look: Select any file on your desktop or in Finder. Press the Spacebar to open Quick Look.
- Three-Finger Swipe Down: While in Quick Look, perform a three-finger swipe down on the trackpad. This gesture toggles the ruler on and off.
- Alternatively: You can also access the ruler through the Accessibility settings. Navigate to System Settings > Accessibility > Pointer Control > Trackpad Options… and enable “Show Ruler.”
Onc activated, a ruler will appear along the top edge of the Quick Look window.
How the MacBook trackpad Ruler Works
The MacBook trackpad ruler isn’t a customary, fixed-length ruler. Rather, it uses the trackpad’s dimensions as a reference point.
units of Measurement: You can switch between inches, centimeters, and pixels using the options displayed alongside the ruler.
Measuring Objects: Drag the endpoints of the ruler to measure the length of objects displayed in the Quick Look window. The measurement will be displayed in real-time.
Calibration: While not user-adjustable, the trackpad is pre-calibrated by Apple for reasonable accuracy. However, it’s important to understand its limitations (see section below).
Beyond Quick Look: Measuring Screenshots
The ruler isn’t limited to files opened in Quick Look. You can take a screenshot (Command + Shift + 4) and then open that screenshot in quick look to utilize the ruler. This is incredibly useful for measuring elements on your screen, like images or website designs.
Accuracy and Limitations
While convenient, the MacBook trackpad ruler isn’t a substitute for a precision instrument. here’s a breakdown of its accuracy and limitations:
Trackpad Size: The ruler’s maximum measurable length is limited by the physical size of your MacBook’s trackpad. Larger MacBooks offer a longer measurement range.
Pixel-Based Measurement: Measurements are ultimately based on pixels, which can introduce slight inaccuracies, especially when dealing with curved lines or complex shapes.
Screen Distortion: Screen curvature or viewing angles can also affect measurement accuracy.
Not for Professional Use: This tool is best suited for quick, approximate measurements. For critical applications requiring high precision, a physical ruler or digital calipers are recommended.
Practical Applications & Real-World Use Cases
The MacBook trackpad ruler is surprisingly versatile. Here are some practical applications:
Graphic Design: Quickly measure image dimensions or element sizes within design software screenshots.
Web Development: Verify spacing and alignment of elements on web pages.
Interior Design/DIY Projects: Estimate the size of furniture or objects in photos.
Photography: Measure the dimensions of subjects in photographs.
Quick Reference: Avoid searching for a physical ruler for simple, everyday measurements.
A designer’s Experience
I recently used the trackpad ruler while reviewing a website mockup. I needed to quickly verify the height of a hero image. Rather of grabbing a physical ruler, I took a screenshot, opened it in Quick Look, and had the measurement within seconds. It saved me valuable time and streamlined my workflow.
Troubleshooting Common Issues
Ruler Not Appearing: Ensure you’ve enabled the ruler in Accessibility settings or are using the three-finger swipe down gesture within Quick Look.
Inaccurate Measurements: Remember the limitations outlined above. For greater accuracy, use a physical ruler.
Gesture Not Working: Check your trackpad settings to ensure the three-finger swipe down gesture is enabled.
Maximizing Precision: Tips & Tricks
Zoom In: Zooming into the Quick Look window can improve measurement accuracy, especially for smaller objects.
* Straight Lines: Ensure you’re measuring along straight lines for
