How to Choose the Perfect Image for your Mobile Phone Cover

Made of silky 100% polyester. No minimum order. Choose from thousands of cool and colorful designs, custom images, or make your own. We also want you to be satisfied with your individual cell phone cover and therefore you will be able to present 3 criteria to help you select your perfect picture.

1 - The optimal resolution

First of all, it is important that you use a picture of high quality. We recommend a file with 300 DPI (dots per inch). A 300 DPI photo is basically a "high-resolution photo". This is important for the printing process, because the higher the DPI, the better the color of the photo and the smoother the print color appears.

In a printing process, the image is converted to small dots. If the print file has too low a resolution, the print image appears pixilated at the end. Even if you do not use a photo, but create your design with an image editor like Photoshop, the print file always consists of pixels.

You can find the resolution of your photos or your file easily by right-clicking on the photo, then clicking on "Properties" and under "Details" you will find the DPI. In general, your photo should look as sharp as possible.

Another important thing, since we often hear, "On my monitor, the picture looks great." The reason for this is that computer monitors usually work with screen resolutions between 72 and 96 dpi. In general, it can be said that a photo that looks good on computer screens is approximately one-third the size when printing.

2 - The correct image dimensions

GoCustomized specifies the optimal picture dimensions for each case, which you should orientate yourself to. You can find them on the right side of the product under the orange box "Create your own design", which leads to our Customizer.

Even if you can not stick to the exact picture dimensions, you should use a photo or design that does not deviate too much from them. Then we can print your design as beautifully as possible on your custom phone case

3 - The right brightness

The photo you decide on should not be too light or too dark, otherwise it may become lighter or darker on the custom phone case.

Even if your photo looks good on your screen, the brightness of your screen may be too high, and the brightness of the photo may not be reflected optimally. So check your screen settings so you do not wonder why your picture on your mobile phone does not look like the original.


If you pay attention to the following points, nothing can go wrong with your design and you should get a beautiful self-designed custom phone case, which shows your photo or design perfectly.

  • High-resolution photo (300dpi) with an optimal file size of 3 MB
  • Note the optimal image dimension for the respective envelope
  • A photo that is neither too light nor too dark

Since you now know what is important in your uploaded picture, we wish you a lot of fun with the design of your unique mobile phone cover!
