Compare phone screen sizes

Two phones or tablets side by side: CSS viewport, pixel ratio, physical resolution and how much of a page is visible once the browser's bars are drawn, all to scale. Each comparison also works out which breakpoints separate the two and what that means for your images and above-the-fold content.

Frequently asked questions

Why compare screen sizes in CSS pixels?

CSS pixels are what media queries, percentages and vw units are measured in. The phones here range from 344 to 440 CSS px wide in portrait; their physical resolutions differ far more because their pixel ratios differ.

Can I compare any two devices?

Yes. Pick any two of the 44 screens in the form at the top of this page. Models that share exactly the same screen, such as the iPhone 16 Pro, 17, 17 Pro, are listed as one.
