Icons are visual shorthand. Used effectively, they help customers navigate a page or a layout quickly, make a decision, and take action.
Streamline icon kit
We primarily use the Streamline icon kit. It contains hundreds of icons and should cover most use cases.
When representing a Twilio product, we always use official product names and official product logos.
Designing an icon
If Streamline doesn’t have the icon we need, we design our own. We want it to feel like it belongs to the Streamline Regular family, while also clearly communicating our concept.
- Must be contained within a 24px x 24px box
- 1.5px stroke
- Rounded corners
- Rounded stroke ends
- One color
Icon scale and cropping
When to use an icon
