Frequently asked questions
Is the Screen Resolution Simulator free?
This tool requires an active one-time membership to use - pay once and unlock this tool plus every other gated tool on the site, no subscription, no ads.
Does this show exactly how my site looks on a real device?
It simulates the viewport dimensions of common devices, which is useful for a quick responsive-design check - but for pixel-perfect testing, real device testing or browser dev tools' device emulation is more thorough.
What screen sizes should I prioritize testing?
Check your site's own analytics for the most common device/screen sizes your actual visitors use, then prioritize those - as a general baseline, a common phone size, tablet size, and standard desktop width cover most cases.
