A pixel ruler is a tool for measuring distances on images. Designers use it to measure UI element spacing and dimensions, frontend developers use it to verify pixel-perfect implementation of designs, and photo editors use it to measure object sizes within images.
Measurement accuracy depends on the image's display scale. The tool accounts for the ratio between the image's actual pixel dimensions and its display size, giving you pixel-level accurate measurements. For best results, use the image at its original size.
Two measurement modes are available: Distance mode measures the pixel distance between two points including width and height differences; Angle mode measures the angle between the line connecting two points and the horizontal axis.
Absolutely not. This tool runs entirely in your browser. Your images are processed locally and never sent to any server. It works perfectly even without internet connection.
This tool works with uploaded images. Take a screenshot of what you want to measure, then upload it to the tool. For measuring elements outside the browser, use your system's screenshot tool first.
This tool uses the HTML5 Canvas API for image rendering and measurement annotations. All calculations are performed locally in your browser, accounting for the ratio between actual image pixel dimensions and display size to ensure accurate results. Your data never leaves your device.
