WhiteWall generally has an upper limit of 2 gigabytes per image file. For illustrated books and photo calendars, the maximum file size is 20 megabytes.
You should always use the maximum available resolution, i.e. no downsized image files. We accept a minimum of 700 x 700 pixels. Maximum is 625 megapixels and up to 50,000 pixels per image page.
Your file must be at least 0.4 megapixels in size (i.e. 700 x 700 pixels). The maximum size for image files is limited to 625 megapixels. So depending on the aspect ratio of your photo, this will result in corresponding maximum dimensions.
Here are a few examples of possible image dimensions per aspect ratio:
| Size | Megapixel | File |
|---|---|---|
| 1:1 | 625.0 | 25,000 x 25,000 px |
| 3:2 | 524.2 | 30,600 x 20,400 px |
| 4:3 | 622.1 | 28,800 x 21,600 px |
| 5:4 | 622.7 | 27,900 x 22,320 px |
| 2:1 | 612.5 | 35,000 x 17,500 px |
| 3:1 | 622.1 | 43,200 x 14,400 px |
| 4:1 | 625.0 | 50,000 x 12,500 px |
