Why test your site on Apple iPhone SE?

2x density

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

Actual media queries

The 375 x 667 pixels viewport of Apple iPhone SE rarely matches the round breakpoints of frameworks. It is precisely between these values that layouts break.

CSS viewport resolution of Apple iPhone SE

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

  • 375 pixels in width
  • 667 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 SE

2

The device pixel ratio of Apple iPhone SE 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 SE

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
  • 16:9 Screen ratio

326 pixels per inch (ppi) · 4.7 inches diagonal, or 11.9 cm

Media queries and code snippets for Apple iPhone SE

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

CSS media query

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

@media only screen and (min-width: 375px) and (max-width: 666px) {
  /* Apple iPhone SE */
}

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 SE.

// tailwind.config.js
module.exports = {
  theme: {
    screens: {
      'apple-iphone-se-2020': '375px'
    }
  }
}

JavaScript detection

Detects format and density client-side.

const isDeviceWidth = window.matchMedia('(min-width: 375px)').matches;
const isHighDensity = window.devicePixelRatio >= 2;

Meta viewport tag

Essential for Apple iPhone SE 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 SE simulator

Mobile FIRST includes Apple iPhone SE: your page displays in a viewport of 375 x 667 pixels, with the model's User-Agent, touch events, and scrolling behavior of a real mobile.

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 SE Select Apple iPhone SE 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 SE

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

Frequently asked questions about Apple iPhone SE

What is the CSS viewport resolution of Apple iPhone SE?

The CSS viewport of Apple iPhone SE measures 375 pixels wide and 667 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 SE?

The device pixel ratio of Apple iPhone SE 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 SE?

The panel of Apple iPhone SE displays 750 x 1334 physical pixels. This is the value reported by most analytics tools, while your CSS works on a viewport of 375 x 667 pixels.

Which devices have the same viewport as Apple iPhone SE?

4 other models share exactly the viewport of 375 x 667 pixels and the 2x density of Apple iPhone SE: Apple iPhone 6, Apple iPhone 6s, Apple iPhone 7, Apple iPhone 8. A rendering validated on one is valid on all others.

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

Install the Mobile FIRST extension on Chrome, Firefox, or Edge, then select Apple iPhone SE. Your page displays in a viewport of 375 x 667 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 SE, 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 SE?

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 SE 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 SE?

A media query on the exact width targets Apple iPhone SE: @media only screen and (min-width: 375px). Combine it with the pixel density to precisely target this model and those sharing its format.
