Apple iPhone 8: CSS viewport of 375 × 667 px, resolution and responsive test

Why test your site on Apple iPhone 8?

CSS viewport resolution of Apple iPhone 8

This resolution is what your stylesheet actually manipulates. It determines the applied breakpoint, the number of displayed columns, and the size of your images.

The height remains indicative: Safari, Chrome, and other mobile browsers reduce the visible area with their address bar, which folds on scroll.

Be cautious when analyzing your statistics: some tools only report the manufacturer resolution, never the CSS viewport presented here.

Pixel density of Apple iPhone 8

The device pixel ratio of Apple iPhone 8 is 2. Each CSS pixel is thus rendered by 2 physical pixels, making any image provided in simple resolution immediately visible.

Manufacturer resolution of Apple iPhone 8

This is the number of physical pixels on the screen, as announced by the manufacturer. Useful for preparing your image exports, useless for your media queries.

• 750 pixels in width
• 1334 pixels in height
• 326 pixels per inch (ppi)
• 4.7 inches diagonal, or 11.9 cm

Mobile FIRST does not yet include Apple iPhone 8, but a model with the same format is available. You can already validate your breakpoints and display density.

This is where the difference with Chrome DevTools' responsive mode is seen: DevTools resizes a window, the extension replicates the device's browser and allows exporting shareable screenshots and videos.

1. 01 Install the extension — Add Mobile FIRST to Chrome, Firefox, or Edge. Installation is free and requires no account.
2. 02 Open the page to test — Go to the URL to check, including a local address like localhost:3000.
3. 03 Choose Apple iPhone 8 — Select Apple iPhone 8 from the list of devices. The viewport switches to 375 x 667 pixels, and the mobile User-Agent is applied.
4. 04 Check rendering — Scroll, change orientation, test your forms, then capture an image or video to share.

Models sharing the format of Apple iPhone 8

These 4 devices share exactly the viewport of 375 x 667 pixels and the 2x density of Apple iPhone 8. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.
