Why test your site on Apple iPhone 5s?

Narrow viewport

With only 320 pixels wide, Apple iPhone 5s is among the most restrictive formats. This is where tables overflow, titles break poorly, and buttons become too small.

Older hardware

The hardware of Apple iPhone 5s dates from 2013. Its processor makes costly animations, heavy scripts, and display times visible that recent devices mask.

2x density

With a density of 2x, Apple iPhone 5s provides a useful benchmark to ensure your images remain sharp without serving unnecessarily large files.

CSS viewport resolution of Apple iPhone 5s

This is the width your CSS considers. All your breakpoints and media queries compare to this value, not the number of physical pixels on the panel.

  • 320 pixels in width
  • 568 pixels in height

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 5s

2

The device pixel ratio of Apple iPhone 5s is 2.

Your images should therefore be exported 2 times larger than their display size, otherwise they will appear softened on this screen.

Manufacturer resolution of Apple iPhone 5s

This is the actual number of pixels on the panel. This value does not affect your layouts, but it's the one reported by technical specifications and most analytics tools.

  • 640 pixels in width
  • 1136 pixels in height
  • 16:9 Screen ratio

326 pixels per inch (ppi) · 4 inches diagonal, or 10.2 cm

Media queries and code snippets for Apple iPhone 5s

These snippets are generated from the exact characteristics of Apple iPhone 5s. Copy them directly into your stylesheet or configuration.

CSS media query

Targets screens whose width matches that of Apple iPhone 5s and models of the same format.

@media only screen and (min-width: 320px) and (max-width: 567px) {
  /* Apple iPhone 5s */
}

Density media query

Serves high-resolution images to screens of at least 2x.

@media only screen and (-webkit-min-device-pixel-ratio: 2),
       only screen and (min-resolution: 192dpi) {
  /* High-density images and icons */
}

Tailwind configuration

Adds a named breakpoint at the exact width of Apple iPhone 5s.

// tailwind.config.js
module.exports = {
  theme: {
    screens: {
      'apple-iphone-5s': '320px'
    }
  }
}

JavaScript detection

Detects format and density client-side.

const isDeviceWidth = window.matchMedia('(min-width: 320px)').matches;
const isHighDensity = window.devicePixelRatio >= 2;

Meta viewport tag

Essential for Apple iPhone 5s to use its CSS viewport and not a simulated width of 980 pixels.

<meta name="viewport" content="width=device-width, initial-scale=1">

Free Apple iPhone 5s simulator

Mobile FIRST does not yet include Apple iPhone 5s, 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 5s Select Apple iPhone 5s from the list of devices. The viewport switches to 320 x 568 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 5s

These 3 devices share exactly the viewport of 320 x 568 pixels and the 2x density of Apple iPhone 5s. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.

Comparison with similar models

The neighboring formats of Apple iPhone 5s are the ones to test right after, as they reveal poorly placed breakpoints.

Frequently asked questions about Apple iPhone 5s

What is the CSS viewport resolution of Apple iPhone 5s?

The CSS viewport of Apple iPhone 5s measures 320 pixels wide and 568 pixels high. This is the width to use for defining your media queries, not the manufacturer's resolution.

What is the pixel density of Apple iPhone 5s?

The device pixel ratio of Apple iPhone 5s is 2. Each CSS pixel is thus displayed by 2 physical pixels, requiring you to provide your images in 2x to keep them sharp.

What is the screen resolution of Apple iPhone 5s?

The panel of Apple iPhone 5s displays 640 x 1136 physical pixels. This is the value reported by most analytics tools, while your CSS works on a viewport of 320 x 568 pixels.

Which devices have the same viewport as Apple iPhone 5s?

3 other models share exactly the viewport of 320 x 568 pixels and the 2x density of Apple iPhone 5s: Apple iPhone 5, Apple iPhone 5c, Apple iPhone SE. A rendering validated on one is valid on all others.

How to test my site on Apple iPhone 5s without the device?

Install the Mobile FIRST extension on Chrome, Firefox, or Edge, then select Apple iPhone 5s. Your page displays in a viewport of 320 x 568 pixels with the corresponding mobile User-Agent, in two clicks and for free.

What is the difference with Chrome DevTools' responsive mode?

DevTools resizes the window and applies partial emulation. Mobile FIRST additionally applies the User-Agent of Apple iPhone 5s, touch events, scroll behavior, and the actual appearance of the device, and allows capturing directly usable images and videos.

Can I test a localhost address on Apple iPhone 5s?

Yes. The extension works on any URL open in your browser, including localhost:3000, 127.0.0.1, or a password-protected pre-production environment.

Do you need to buy a Apple iPhone 5s to test your site?

No. The simulation covers the vast majority of development needs at no cost. A final test on a real device is still recommended before critical production deployment, but it's no longer necessary for each iteration.

Which media query to use to target Apple iPhone 5s?

A media query on the exact width targets Apple iPhone 5s: @media only screen and (min-width: 320px). Combine it with the pixel density to precisely target this model and those sharing its format.
