Modern Device Dimensions for Chrome DevTools

These are modern “Emulated Devices” (a.k.a. responsive dimensions) for Chrome DevTools’ Mobile Device Viewport Mode.

They are specifically Apple devices, subtracting for recent Safari UI (as in window.innerWidth/Height), and cleverly sorted with some dark-arts unicode shenanigans. (This glitchy, unloved portion of the tools sorts lexicographically, because of course it would.) Ergonomics!

before-after

Nest Hub Max? Come on. I dropped a bunch of devices that were older and/or close to these dimensions. It obviously doesn’t cover everything (sorry Android/Chrome), but offers a decent spread/increments for common 2023/2024 viewports.

There seems to be no easy way to share or sync these, and manually entering them is an error-prone disaster. So instead, this is the relevant portion of the profile’s (JSON…ish?) Preferences file (under ~/Library/Application Support/Google/Chrome/Profile #/) to paste in.

It’s probably easiest to just make one custom device, then search for the customEmulatedDeviceList key. VS Code’s Format Document (⌥ ⇧ F) command makes these intelligible, and Chrome doesn’t seem to mind. Great.

Godspeed. 👇

And the dimensions, for posterity:

Device W (logical) H (logical) W (inner) H (inner) Notes
iPhone SE 320 568 320 449 iOS 15.5. The last great iPhone chassis.
Common Android 360 780 360 649 Galaxy S23 on Android 13 seemed indicative.
iPhone SE (3rd) 375 667 375 547 iOS 17.2. Only remaining/current home-buttoned iPhone.
iPhone 15 390 844 393 659 iPhones Pro are the same this year.
iPhone 15 Plus 428 926 430 739 These have the default bottom “Tab Bar” setting. Close enough to the 414px of the X/11 era.
iPhone SE, landscape 568 320 568 270 Tab bar is always at the top in landscape.
Common Android, landscape 780 360 705 280
iPhone SE (3rd), landscape 667 375 667 325 With the “Landscape Tab Bar” on—I think the default?
iPhone 15, landscape 844 390 743 310 Multiple tabs visible. These are inside the left/right safe areas.
iPhone 15 Plus, landscape 926 428 814 347
iPad Mini (6th) 744 1133 744 1026 Default “Separate Tab Bar” option, multiple tabs visible.
iPad (10th) 820 1180 820 1073 Same dimensions for the recent iPads Air. Close to 11" Pro.

Thanks! This is helpful!

Worked nicely, but in my preferences JSON file, the key was named custom-emulated-device-list, not customEmulatedDeviceList. I didn't notice that immediately and wondered why things didn't work when I copy-pasted from this gist.

I would also suggest editing this JSON file while Chrome is closed because otherwise it might override these preferences. At least to me it seemed like they were being overridden when I edited this file while Chrome was open.

The title string contains 2x ZERO WIDTH SPACES for lot of entries. Is it intentional?

// Verify
const str = '[{\"title\":\"​iPhone SE\",\"type\":\"unknown\",\"user-agent\"...';
const count = str.match(/\u200B/g)?.length ?? 0;
console.log(`ZERO WIDTH SPACE (U+200B) characters: ${count}`);
// out: ZERO WIDTH SPACE (U+200B) characters: 305

// fix
str.replace(/\u200B+/g, '');

EDIT: Nevermind, I see it is used to make sorting more logical.

I can't seem to make this work. I modified the settings when chrome is closed, and when I open it, the settings are overridden. Btw, I'm on windows 11.

Try adding a custom profile through Chrome dev tools first. Then open those JSON settings and see under which key these new settings are stored. This gist says that customEmulatedDeviceList is the name of the JSON key, but for me on Windows it was a key named custom-emulated-device-list.

On my Mac it was custom-emulated-device-list too.

Hi! I recently updated my cli tool called "vibranium".
It will import and export the settings that we are talking about here.
I hope this tool will save us all.

https://www.npmjs.com/package/@pittankopta/vibranium

  • Save this file as whatever.json
  • npm i -g @pittankopta/vibranium
  • vibranium add whatever.json
