How to Use This Free Screen Coordinates Tool

This online screen coordinates tool helps you find the exact X and Y coordinates of your mouse pointer on the screen. An essential utility for frontend developers, UI/UX designers, and QA testers.

1. Choose Origin

Select where the (0,0) point should be. "Top Left" is standard for websites.

2. Choose Resolution

Pick "Native" for physical pixels or "Display" for CSS pixels (with DPI scaling).

3. Start

Click Start to enter fullscreen. Move mouse to see coordinates.

4. Measure Desktop Elements (Screenshot Mode)

Press PrtSc (Print Screen) to capture your desktop (entire screen screenshot). Return to this tool and press Ctrl+V. The screenshot will become the background, allowing you to measure coordinates of any desktop application.

Frequently Asked Questions

How to find X Y coordinates online?

Open this tool, select origin, and move your mouse.

Difference between native and display resolution?

Native refers to physical pixels. Display includes scaling factor (DPI).

Why use this tool?

It's a free screen coordinates tool for verifying pixel-perfect designs, debugging, and automation scripts.

Can I measure coordinates of other applications?

Yes! First minimize this site, open the app or page you want to capture, and press PrtSc (Note: capture the full screen). Then return here and paste by pressing Ctrl+V. The tool will load your screenshot as the background, allowing you to measure any position on it.

Understanding Screen Coordinates & Resolution

What are Screen Coordinates?

Screen coordinates are a system used to specify the position of a point on a computer display. In web development and most graphical user interfaces, the coordinate system typically starts from the top-left corner of the screen, which is designated as (0,0). The X-axis increases as you move to the right, and the Y-axis increases as you move down. This is different from the standard Cartesian coordinate system used in mathematics, where the Y-axis usually increases upwards.

Client vs. Screen vs. Page Coordinates

Screen Coordinates: Relative to the physical screen of your device.
Client Coordinates: Relative to the visible viewport of the browser window.
Page Coordinates: Relative to the entire document (including scrolled areas).

Why Resolution Matters

Modern displays have high pixel densities (Retina, 4K, etc.). This introduces a distinction between physical pixels and CSS pixels. For example, a "Retina" screen might have a physical width of 2000 pixels but report a CSS width of only 1000 pixels (Device Pixel Ratio of 2). This tool allows you to switch between "Native" (physical) and "Display" (CSS) modes to understand this relationship better.

Applications in Development

Precise coordinate tracking is crucial for:

Game Development: Determining where a player clicks or moves within the game world.
Canvas Drawing: Rendering graphics dynamically based on user input.
UI Testing: Verifying that elements are positioned exactly where designed.
Accessibility: Ensuring interactive elements are reachable and properly sized.
