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 (e.g. 'Programmable Voice', not 'Voice') 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. Contact the brand team if you need a custom icon.
- Must be contained within a 24px x 24px box

Icon scale and cropping
When to use an icon
Used intentionally, icons help make a page more readable and drive a customer to take action. It is important to understand when an icon or a spot illustration is more appropriate.
