B. Cropping

Photographic film traditionally (24x36) has a ratio of three long by two high (3/2).

In digital photography, it is usual to work with different proportions of images, the most common are 3/2, 4/3, 1/1 and 16/9. Some devices offer less common ratios like 5/4 and 2/1.

By default, we print your photos respecting the original framing.
Our website helps you by automatically detecting the most classic ratios. So by default the proposed sizes are:

3/2
10x15 cm
4/3
11x15 cm
1/1
10x10 cm
16/9
10x18 cm
Autre

Width of 10 cm and length of 18 cm maximum.

  • 10L format for ratios smaller than 16/9. (Width 10 cm, length according to the proportion).
  • 18C format for ratios larger than 16/9. (Length 18 cm, width according to the proportion).

If you choose a different ratio from that of your file, with the option "original" you will get a white border on 2 sides of the image and with the option "full sheet", your images will be cropped to fill the entire format selected (see example below).
