# Rethink 16:9 media on a 1.42 display

> The inner display's aspect ratio is roughly 1.42, so a 16:9 video letterboxes heavily. Full-bleed assets designed for a tall phone crop badly.

Severity: blocker
Category: layout
Applies to: all
Symptom: Video sits in a small band with thick black bars, or a full-screen background image is cropped to an unrecognisable centre slice.

The inner display is 626 × 890 points, an aspect ratio of about **1.42**. For comparison, iPhone 18 Pro is about **2.17**. That is not a small adjustment — it is a different shape of screen.

## Why it happens

A 16:9 video (1.78) placed on a 1.42 display cannot fill it. Fitted to the width, it occupies roughly 890 × 501 points and leaves around 125 points of letterbox split between top and bottom — close to a fifth of the display.

That is still a considerably larger picture than on a standard iPhone, so the fix is not to fight the letterbox but to use the space it frees.

## The fix

**For video**, treat the leftover space as a feature. The gap below a fitted player is well suited to the controls, episode list, or transcript that previously required a separate screen. Apple's `ArrangementView` exists precisely for this main-plus-secondary relationship:

```swift
ArrangementView {
    PlayerView()
} secondary: {
    UpNextView()
}
.arrangementViewStyle(.split)
```

Resist `.resizeAspectFill` as a reflex. Filling a 1.42 display with 16:9 content crops roughly a quarter of the frame width, which is unacceptable for anything where the edges carry meaning.

**For images and backgrounds**, provide art that tolerates a squarer crop, or compose with a focal point rather than relying on a fixed aspect. Full-bleed assets cut for a 2.17 phone will lose their subject on this display.

**For documents and feeds**, the 1.42 ratio is close to √2 — the proportion behind A-series paper. Page-shaped content, reading views, and two-column layouts fit it unusually well. This is the case where the new shape is an advantage rather than a constraint.

## How to verify

Play your primary media on the inner display in every pose. Check that nothing important is cropped, that the letterbox area is either used or deliberately empty, and that rotating does not resize the video jarringly mid-playback.
