Frequently Asked Questions (FAQ)
What is screen resolution?
Screen resolution refers to the number of pixels your screen displays horizontally and vertically. For example, 1920×1080 means 1920 pixels wide and 1080 pixels high.
What is viewport size?
The viewport size is the visible area of a web page in your browser, excluding elements like toolbars or scrollbars. It can vary depending on browser size and zoom level.
How accurate is the zoom level detection?
The zoom level is an approximation based on the ratio between outer and inner browser widths. While it's generally reliable, minor differences may occur across devices or browsers.
Does this tool store any personal data?
No. All detections are processed entirely in your browser. No data is collected, stored, or sent to any server.
