This tool compares the screen rectangle using display size and resolution ratio. Rounded corners, camera cutouts, and notches are simplified. The phone body outline is derived from manufacturer body dimensions — the screen is shown centered within the body, which is accurate for most modern flagships. Some budget and older phones (such as certain Pixel a-series and Galaxy A-series models) have a slightly larger chin than forehead, so the screen position may be a few pixels off from reality.
