Screen Center Finder
Mark the exact center of your display. Go full screen for a precise crosshair, center lines, corner diagonals, and an optional rule-of-thirds grid — then read off the exact center pixel and your screen resolution.

Put a crosshair at dead center to line up a camera or facecam for streaming and calls.
Read the exact center pixel to place a sticker or tape cross for mounting and calibration.
Use the center lines and diagonals as a target to square up a projected image.
What is the center of the screen?
The center is the point exactly halfway across and halfway down the display — on a 1920 × 1080 screen, the pixel at 960 × 540. Easy to eyeball, hard to hit precisely: small offsets show the moment you align a camera, a physical marker, or a projected image against it. Every guide here meets at that point, so you can trust the mark instead of guessing.
How is the center computed?
The center is simply half the width and half the height. The tool reports two figures: the drawing area in CSS pixels (what the browser lays out) and your screen resolution from the operating system. On a high-DPI display these differ — a Retina laptop may report a 1512-pixel-wide layout while the panel packs far more physical pixels — but the midpoint is the same relative point either way. Guides are drawn on a canvas scaled to your device pixel ratio, so the crosshair stays crisp on the true half-pixel instead of blurring across two.
A note on multiple monitors
The guides and readout describe the display this browser window is on, not your whole desktop. If you span several monitors, move the window onto the screen you want before going full screen. Each screen has its own resolution and its own center, so recheck the readout after switching displays.
