Middle of My Monitor
Tip: Go Fullscreen for the true monitor center line, ruler, and camera alignment across your whole display. All toggles stay in the panel in fullscreen.
Instantly find the middle of your monitor. This tool draws a vertical and horizontal line that cross at the exact center of your screen, plus a calibrated display ruler, camera alignment, and a microphone test. Wondering where's the middle of my screen? Hit fullscreen and the monitor center line will span your whole display.
Finding the Center of Your Screen
Knowing where the middle of your monitor is sounds simple, but eyeballing it rarely lands on the true center of screen. This tool removes the guesswork: it places a precise line down the middle of the monitor both vertically and horizontally, so the screen center is marked exactly. Whether you call it the center of my screen, the monitor center line, or simply the middle of the screen, the guides update live as you resize your window or switch into fullscreen.
Features
Center Lines & Crosshair
A vertical and horizontal line down the middle of the monitor, meeting at a crosshair on the exact center of the screen. Toggle each guide independently to show just the line you need.
Calibrated Display Ruler
Enter your monitor size and measure real inches or centimeters directly on screen, with the ruler scale running through the screen center for precise on-screen measurement.
Align Camera
Overlay your webcam under the center guides to line up your face or an object with the monitor center — ideal for streaming, video calls, and recording.
Test Microphone
A live input-level meter lets you check your microphone is picking up audio, right alongside the camera and center tools.
