Your device pixel ratio is .
If the wallpaper you want is available in multiple resolutions but not in the exact resolution of your screen, you'll need to consider a few factors to pick the best one. Here's how to approach the situation:
First and foremost, try to match the aspect ratio of the wallpaper to the aspect ratio of your screen. This ensures the image doesn't get distorted when it's set as a wallpaper. Common aspect ratios include 16:9 (e.g., 1920x1080, 2560x1440), 4:3 (e.g., 1024x768, 1600x1200), 21:9 (e.g., 3440x1440), among others.
It's better to download a wallpaper that's larger than your screen's resolution rather than one that's smaller. A larger image can be scaled down to fit your screen without losing much clarity.
On the other hand, if you pick a wallpaper with a resolution that's too small, it'll need to be stretched to fit your screen, which can lead to a pixelated or blurry appearance.
If you're choosing for a device that can be used in both landscape and portrait (like smartphones and tablets), you might prioritize a resolution that matches the most common orientation you use.
However, as a general rule for such devices, choosing a wallpaper that's larger in both dimensions gives you flexibility to rotate the device without encountering low-res areas.
If you can't find an exact match in terms of aspect ratio or resolution, be prepared to crop the image. If you're choosing a larger resolution image, you can crop it to fit your screen's aspect ratio without much loss in clarity.
Use image editing software or apps that allow you to crop according to specific resolutions or aspect ratios. This way, you can select the most important or attractive part of the wallpaper to display.
Even if an image is available in a larger resolution, ensure that it's of high quality. Sometimes images are artificially upscaled which can make them appear blurry. Avoid images with noticeable artifacts, compression issues, or other quality problems.
After selecting what seems to be the best resolution, download it and set it as your wallpaper. Evaluate how it looks. If it doesn’t meet your expectations, you can always try another resolution or make adjustments with image editing tools.
If you're comfortable with image editing, consider downloading the highest resolution available and then customizing it to fit your needs. This might mean cropping, resizing, or even enhancing colors and details.
In general, it's a mix of understanding your device's specs and a bit of trial and error. Don't be afraid to experiment to find what looks best on your screen.
