Orbis Accessibility Guide

General information

Orbis is committed to improve its accessibility both on social media and its events. Below you can find information in English on the accessibility practices that Orbis aims to follow.

The guide is also available as a downloadable PDF-file.

Alt Text

Alt Text (alternative text) is a written version of an image accessible to screen readers. When adding Alt Text to images, think about what is most important in the image: keep it short but descriptive! Break each item with a comma. 

If the image contains text, include the message in alt-text. Do not repeat the caption.

Color contrast

Paying attention to color contrast is important because it affects the visibility of the content. You can use free accessibility checkers to check the color contrast of your content (for example Webaim and Wave)


Make sure to describe where each link will lead.

Instructions for different platforms


Add captions and alt text to images. Although Facebook offers machine-generated alt text, edit it to add more context. Click the three dots at the corner of an image and then “Change alt text”.

Avoid using acronyms.

Check color contrast on images; place text over a solid, high-contrast background.

Use descriptive link text.

Capitalize each word in hashtags.

When sharing events onto the page, include in the description alt-text for the previewed event image.

In-person events

Event descriptions must include information on accessibility, the principles of safe space, along with any other relevant safety information. 

At the moment, the New Student House is inaccessible for wheelchair users. When hosting an event at the New Student House, In the event description give contact information in case someone is unable to access the building, and have an alternative location that can include attendees in wheelchairs. 

Offer to meet any people who need assistance in accessing the location.


Add hashtags in the comments or at the end of the caption. Capitalize each separate word in hashtags. For example: #UniversityOfHelsinki

Use alt text. When creating a new post, on the last page before posting, tap “Advanced settings” at the bottom of the page. Then choose “Write Alt Text”. You can also add alt text to existing images: tap the three dots next to your image, choose “Edit”, and then “Edit Alt Text”.

For Alt. text, remember it is not visible, unless using a screen reader. Use commas to break long sentences in smaller pieces, for more fluidity for screen readers users. 

In Instagram stories or other videos, provide captions whenever someone is speaking. 

When posting stories, remember that they are not accessible to people who need screen readers, so if there is key information, make a post about it.
