Home Screen Design Guide: Best Image Sizes for Icons, Wallpapers, and Widgets (Made on Your Phone)

Last updated: 2026/02/06

If you want to make your iPhone or Android home screen look beautiful,
knowing the optimal image sizes makes everything cleaner and easier.

Wallpapers, icons, widgets — each element has a recommended image size
that prevents distortion and keeps your layout consistent.

This guide summarizes the essential image sizes
for anyone designing a home screen directly on their phone.

1. Best Image Size for Home Screen Icons (Web Icons)

When saving a web icon (WebClip) to your home screen, use:

• 1024 × 1024 px (recommended)
• PNG format (transparent background allowed)
• No need for rounded corners — iPhone applies them automatically

The 1024px size ensures crisp visuals on both iPhone and Android.
OJapp also uses this size as the default for icon generation.

Note:
White backgrounds + thin lines may appear faint when shrunk.
High contrast and clear shapes are safer.

2. Best Wallpaper Sizes for iPhone (Lock Screen / Home Screen)

Modern iPhones use high-resolution wallpapers. Examples:

• 1290 × 2796 px (iPhone 15 Pro Max)
• 1179 × 2556 px (iPhone 15 / 15 Pro)

Even if you create an image that perfectly matches the device resolution,
iPhone will crop the top and bottom slightly due to:

• Parallax effect
• Safe area adjustments
• Home screen layout margins

To avoid unwanted cropping:

• Leave breathing room on left and right
• Place important elements slightly lower
• Keep text near the center area

To check composition safely, split your wallpaper using
OJapp Splitter → 3:4 mode.

3. Best Image Sizes for Widget Designs

Widget sizes differ by app,
but the following are widely accepted safe resolutions:

■ iPhone Widget Sizes (Common Image Widgets)

• Small: 510 × 510 px
• Medium: 1090 × 510 px
• Large: 1090 × 1140 px

Ratio-wise:

• Small → Square
• Medium → Wide rectangle (approx. 2:1)
• Large → Tall square-like shape

Designing in Square or 3:4 format first makes resizing easier.

4. Useful Aspect Ratios for SNS Posting

These ratios are easiest to edit directly on your phone:

• 1:1 → Instagram grid, profile icons
• 3:4 → Natural for mobile photos
• 9:16 → Reels, Shorts, TikTok

OJapp Splitter focuses on Square and 3:4
because these cover most mobile-oriented layouts.

5. Recommended Sizes When Using OJapp Tools

If you’re designing your home screen entirely on your phone, follow this rule:

• Icons → 1024 × 1024 px
• Wallpaper composition → Check using 3:4 splits
• SNS feed layout → Split into square tiles

Since Splitter uses fixed ratios,
you never have to worry about “which size should I choose?”

Conclusion: You Can Design a Full Home Screen Using Only Your Phone

Designing a beautiful home screen isn’t about complex apps —
knowing the correct image sizes is the real key.

With the right dimensions for icons, wallpapers, widgets, and SNS posts,
you can build a clean, unified home screen with nothing but a smartphone.
