An abstract wallpaper design is always a safe bet for adding a touch of modern elegance to any screen. Here are some of our favorite abstract wallpaper designs.

You do not need Photoshop skills or a design degree to build a wallpaper from scratch. Piktochart’s wallpaper maker gives you a drag-and-drop canvas, a library of icons and images, and dozens of pre-sized layouts for both desktop (16:9) and mobile (9:16) screens.

Pick a template or start blank. Browse the desktop wallpaper templates or phone wallpaper templates and choose one close to the style you want.

Customize the details. Swap colors to match your aesthetic. Upload your own photos or pull from the built-in image library. Add text, adjust fonts, and move elements around until the layout sits right.

Choose the right size for your device. Desktop monitors typically run at 1920 x 1080 pixels (16:9). Phones need a vertical format; 1080 x 1920 (9:16) covers most iPhones and Android devices. Tablets sit somewhere in between at 2048 x 1536.

Export and set as your background. Download the finished file as a high-resolution PNG. On Windows, right-click the image and select “Set as desktop background.” On Mac, open System Settings and drag the file into the Wallpaper panel. On iOS or Android, save the image to your camera roll, open it, and tap “Set as Wallpaper.”

The full process takes less time than choosing a wallpaper from a stock-photo site, and the result is something no one else has.
