What this tool calculates
See browser, platform, screen and viewport information. The main inputs on this page are the labelled values in the calculator. The result is intended to be readable immediately, with the explanation below available when you need to verify the method.
Method and calculation basis
The result comes from browser-exposed device or event information. Browser permissions, privacy restrictions and hardware support can limit what a web page can observe.
Worked examples
Simple verification
Start with small values where the expected scale of the answer is obvious.
Real-world use
Enter the actual values only after checking units and interpreting the output labels.
Understanding the result
The output should be read in the units shown beside the result. If you are comparing alternatives, keep all unchanged assumptions identical and alter one input at a time. That makes it easier to see which value is responsible for the difference.
Assumptions, edge cases and accuracy
Browser security and privacy controls may deliberately hide or approximate hardware information. A failed browser test does not by itself prove defective hardware.
