Image aspect ratio at aalto.fi
What is aspect ratio?
The aspect ratio of an image describes the proportional relationship between its width and its height, no matter how big the image actually is. It is commonly expressed with two numbers, separated by a colon, as in 16:9.
Current aspect ratios used on the aalto.fi platform:
Original ratio | 1:1 | 1.6:1 | 1.8:1 | 2.3:1 |

Original ratio
The aalto.fi site allows you to display images that are rendered with their original ratio (without any cropping). This is recommended if you need to display an image in its entirety, such as an infographic or a logo. These are the components that feature images with Original Ratio:
-
Single image: when adding a single image to your page, set the Medium display mode. Read more under Single image
-
Image with text: when adding a single image to your page, set the Default image display mode. Read more under Image with text
-
NB for Content pages, only on Main Image: when defining an image as the Main Image, set the Medium No-Crop setting.

1:1 – Square ratio
The square aspect ratio will crop the image to fit within a square (or a circle).This aspect ratio is used in a variety of spaces across the platform, including:
- Manual Liftups
-

-
News and Events listings (on desktop view)
For hub editors only: you can set your own hub page main image to fit into a 1:1 circle with the Hub Description component, by setting the Medium display mode. Read more under Hub description

No. You can display un-cropped images on your own pages by using the correct display mode for the Single Image component or the Main Image component: these images will be rendered with their Original-Ratio. Read more about it in the Original Ration chapter earlier on this page.
