About this icon

Use the Thermometer Alert Outline Rounded icon

The Thermometer Alert Outline Rounded icon from Material Symbols fits naturally in general-purpose product UIs, design systems, component libraries, web applications, and marketing sites.

Export formats

Copy clean SVG vectors with one click, generate custom-size PNG files from 16px to 512px, export JSX/React components ready to paste into your project, or use the icon as a CSS background-mask for flexible theming.

All exports are based on the same editable vector — so the Thermometer Alert Outline Rounded icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

Thermometer Alert Outline Rounded belongs to Google's Material Symbols, which replaces static icon files with a variable font. Weight, Fill, Grade and Optical Size are all adjustable axes, so one file covers what used to need five. Optical Size is the most useful: the glyph is subtly redrawn for small sizes rather than just scaled down.

UX best practices

As a general interface glyph, the Thermometer Alert Outline Rounded icon does its job best between 16px and 24px, sitting next to a text label. Icon-only treatments work for a small set of universally understood actions, but comprehension falls off quickly once the action is specific to your product — so when in doubt, add the word.
