# Phone wallpaper generator for lock and home screens

> The phone wallpaper generator makes tall 9:16 wallpapers from a sentence: 1440 × 2560 at 2K or 2304 × 4096 at 4K with Seedream 4.5 for 10 credits, or up to 3072 × 5504 with Nano Banana 2 for 20 credits. Each request asks the model to keep the top quarter calm, where the clock sits. Download the image and set it in your phone's wallpaper settings.

Describe a scene and get a tall 9:16 wallpaper for iPhone or Android, with the main subject kept clear of the lock-screen clock.

## Why it works on a phone

- **Built tall, not cropped**: The model draws the scene at 9:16 from the start, so only a thin strip at the sides is trimmed when you set it, unlike a landscape photo squeezed onto a phone.
- **Clear of the clock**: Every tall request asks for a calm top quarter, where the time and date sit on the lock screen, and for the subject to stay away from the bottom edge and its shortcuts.
- **Sharp on large screens**: At 4K, 2304 × 4096 has more pixels than current phone screens, so your phone scales the wallpaper down instead of stretching it.
- **Matching lock and home screens**: Generate the same scene twice, once detailed for the lock screen and once calmer or darker for the home screen, so the icons stay readable.

## How to make a phone wallpaper

1. **Describe the scene**: Say what fills the screen, the mood and the colors, and mention open sky or space at the top.
2. **Keep 9:16 and 4K**: The page starts on 9:16 at 4K; make up to 4 versions in one run.
3. **Download and set it**: Save the image to your photos, then pick it in your phone's wallpaper settings.

## How to set an AI wallpaper on iPhone

Save the image to Photos first, then:

- Open Settings and tap Wallpaper
- Tap Add New Wallpaper, then Photos
- Pick the image and pinch to place it
- Tap Add, then Set as Wallpaper Pair, or customize the home screen separately

## How to set it on Android

The steps differ a little by brand; on most Android phones:

- Save the image to your gallery
- Touch and hold an empty spot on the home screen
- Tap Wallpaper & style, or Wallpaper
- Choose the image and set it for the lock screen, the home screen or both

## Phone wallpaper sizes explained

Most current phones have screens of about 19.5:9 or 20:9, a little taller than 9:16; large flagship screens are around 1320 × 2868 or 1440 × 3120 pixels. When you set a 9:16 wallpaper, the phone fills the height of the screen and trims a thin strip from each side.

That is why 4K is the better choice for phones: 2304 × 4096 has more pixels than the screen in both directions, so the phone only scales it down. At 2K (1440 × 2560) the image is slightly enlarged on the tallest screens, which is rarely visible. Both cost the same.


## Lock screen tips

A lock screen shows the time over the top of the image and shortcuts along the bottom:

- Keep faces and focal points out of the top quarter.
- Leave the bottom edge simple; shortcuts and the home bar sit there.
- Dark scenes keep white text readable and suit OLED screens at night.
- Use one palette on the lock and home screens for a matching pair.
- Avoid tiny lettering; it is hard to read at phone size.

## Phone wallpaper FAQ

### What size is a phone wallpaper here?

9:16: 1440 × 2560 or 2304 × 4096 pixels with Seedream 4.5, and 1536 × 2752 or 3072 × 5504 with Nano Banana 2. Phones trim a 9:16 image slightly to fit their taller screens.

### Does it work for iPhone wallpapers?

Yes. Download the image and set it under Settings, Wallpaper. AI Wallpaper Generator is independent and not affiliated with Apple; iPhone is a trademark of Apple Inc.

### Does it work for Android phones?

Yes. Any phone that can set a photo as its wallpaper can use these images. Android is a trademark of Google LLC, and this site is not affiliated with Google.

### Why are the edges cut off on my phone?

Most phones are taller than 9:16, so they fill the height and trim the sides. Keep the subject near the middle of the frame, or pinch to reposition it when you set the wallpaper.

### Is the phone wallpaper generator free?

Signing up is free and the tips on this page are free, but each wallpaper uses purchased credits: 10 with Seedream 4.5 or 20 with Nano Banana 2. There are no free trial credits.

### Can I make a matching lock screen and home screen?

Yes. Generate the same prompt twice, or add “darker and calmer, fewer details” to the second run for the home screen, and set each one separately.
