The Wider Safari extension lets web pages use the full width of the iPhone Duo‘s outer display, where Safari normally stops short of a column of controls on the right edge. It is a free App Store download that adds a one-tap switch between normal and wide pages.
Wider comes from developer Jordi Bruin, and the app needs iOS 27.1 or later.
Wider switches Safari pages between normal and full width with one tap
Wider adds a round button to Safari’s right sidebar on the outer display. Tap it and the page content extends into the area beside the controls, and tap it again to return to the normal layout.
That gap is the one Apple has been looking at. To give pages more vertical room, iOS moves the controls for Safari and the phone to the side of the outer display, and Safari paints that column in the page’s background color while the content stops at its edge. Apple is investigating a fix in Safari itself, but it has not promised one or set a date.
Room is short on that screen, since Safari 27.1 gives sites a viewport 382 CSS pixels wide in portrait. Apple has also held off on letting every page run under the controls by default, because many sites do not inset all four edges correctly and would end up with text and buttons hidden.
To set it up, install Wider and turn it on in Settings > Apps > Safari > Extensions, then open a site in Safari, allow Wider access from the extensions menu and reload any pages that were already open.
The Wider Safari extension works site by site, and some pages will not stretch
Results depend on the website, and some pages expand cleanly while others have fixed headers or their own layout limits that stop them from stretching. You can adjust Wider for each website or turn it off on a page that looks better without it, and the choice is saved for that site.
When a site misbehaves, the app has a report option, and the developer tries to improve compatibility from those reports. Only the site’s URL is shared.
Wider stays inside Safari, while Brim replaces it
Wider leaves you in Safari and changes how wide each page runs. Brim is a separate browser that its developer says uses on-device Apple Intelligence to move buttons and other elements out from under the selfie camera while pages keep 100% of the screen width.
Brim is in public beta on TestFlight while Wider is a regular App Store download.
