The Web Browser Resolution Tester shows the width and height (in pixels) of your browser window. It helps you see the viewport area, which is the visible part of a website inside the browser. This tool also lets you check the total number of pixels available for display, which is helpful when comparing different screen sizes. Best of all, the tool updates in real-time, so as you resize your browser, the dimensions adjust automatically!

1. The width and height of your browser are shown automatically.
2. The tool displays the viewport size (the visible area), not the full window size.
3. It also shows the total pixels available inside your browser.
4. The resolution updates in real-time as you resize the browser.
5. On mobile or high-DPI devices, the browser may adjust pixels to improve text readability.
6. To see the full browser size on mobile, enable “Desktop View.”
7. Your data is not stored—everything happens inside your browser.

Most commonly used web browser resolutions are:
1. 1920×1080 (Full HD): This is a very common resolution for desktop monitors and laptops, offering a good balance of image quality and screen real estate.
2. 1366×768: Often found on older or budget-friendly laptops and monitors, this resolution is still relatively common.
3. 1440×900: Another popular resolution, particularly for mid-range monitors.
4. 1280×720 (HD): A standard resolution for lower-end laptops and entry-level monitors.

Screen resolution refers to the total number of pixels your monitor can display, while browser resolution is the number of pixels visible within the browser window. Since toolbars, scrollbars, and other interface elements take up space, the browser resolution is always equal to or smaller than the screen resolution.
