Screen Size Checker
See any website on phones, tablets and desktops side by side, in portrait or landscape. Made for designers, developers and project managers signing off a website.
Website and devices
Type a website address above to see it on each screen.
How to use it
- Type a website address and pick the screens to check. Each one shows the real site at that screen's width and height, and you can scroll, tap and click inside it.
- Switch to Landscape to turn every phone and tablet sideways, or use the ⟲ button on a single screen.
- Copy share link makes a link with the website and the screens you picked, so a client or teammate sees the same set.
- Some sites (Google, Facebook, most banks) refuse to open inside another page, so their screen stays blank. Use ↗ to open the site in a window at that screen's size instead.
- It checks your layout at each screen size. It doesn't pretend to be the device itself, so sites that show a different page to phones based on the browser name may still show the desktop version. Always test on one real phone before launch.
- Checking a site on your own computer?
http://localhostaddresses work too. Nothing you check is sent to this site; your screen picks are saved in your own browser only.
