Mini Lesson
Accessibility means making things people can use no matter how they see, hear, move, or read. Inclusive design starts at the beginning — you plan for many kinds of users from the first sketch, not as an add-on at the end. When tech is accessible, more people can join in. That is fair, kind, and smart design.
Six Accessibility Features You Can Add Today
You do not need to be an expert to make your slides, videos, and posts more accessible. These six features cover most of what real users need. Build the habit of checking each one before you share.
- Alt text on images — short words that describe what the picture shows so screen readers can speak it.
- Captions on video — text on screen so viewers who are hard of hearing can follow along.
- High color contrast — dark text on light backgrounds (or the reverse) so words are easy to read.
- Keyboard navigation — make sure every button works without a mouse, just with the Tab and Enter keys.
- Clear language — short sentences and common words instead of jargon, so everyone understands.
- Large readable font — pick at least 16 pixels for body text and avoid super-thin fonts.
Designing for Different Users
Different people use tech in different ways. Inclusive design means thinking about all of them — not just the user that looks like you. Here are four user groups and one accommodation each that helps them.
- Low vision — high contrast colors and the ability to zoom text up without breaking the layout.
- Hard of hearing — captions on every video and visual signals (not only sound) for alerts.
- Motor differences — full keyboard navigation and large click targets, so users do not need precise mouse moves.
- English-as-second-language — clear language, short sentences, and icons that support the words.
Why Inclusive Design Wins
Accessible design helps the user it was made for, but it usually helps everyone else too. Captions help the deaf user AND the kid watching on a quiet bus. Big buttons help the user with shaky hands AND the user holding a phone in one hand. Clear language helps the new English speaker AND the tired reader. When you design for the edges, you raise the bar for the middle.
Tip: before you share a slide deck or post, run the six-item checklist. Even fixing two of the six items makes your work easier for many more people.
