It’s only possible to print your photo as a wall mural if the image is at least one pixel per mm of wallpaper. So to cover a wall with size 360 x 240 cm, you will need an image with minimum resolution of 3600px x 2400px. The resolution determines how sharp your wallpaper will be on the wall. The proportions of the image should match the proportions of your wall – otherwise, some areas will be cut out – but don’t worry you can test how this looks after uploading your image. If you wish to use a higher quality image than the one you upload, simply upload the image in low quality, place your order and reply to your order confirmation with a WeTransfer or Dropbox link and we will happily use this high res image for your customized wallpaper design.
To determine if the image quality is good enough, try uploading your image. Our system will let you know what size is the maximum. To ensure high quality, we will review your image before we print and contact you if we have any questions or suggestions for improvements.
