Button text should be set in sentence case, with only the first word in a phrase and any proper nouns capitalized.

A button cannot have any element or text within 16 pixels / 1 rem of its borders. For button groups, the primary button is positioned on the outside of the set, while the secondary button is positioned inside. For a button with a glyph, the space between the button label and the glyph must be greater than or equal to 16 pixels / 1 rem. This is to accommodate for instances where two or more buttons with glyphs appear together.

There are three common button sizes: default, inline, and small. Each button type can use any of these three sizes based on need. The fourth button size, full bleed, has a more reserved application and should rarely be used.

Button sizeHeight (px / rem)Use case
Full bleed64 / 4Use when buttons bleed to the edge of a component, like in side panels and modals.
Default48 / 3Use as primary page actions and other standalone actions.
Inline40 / 2.5Use when buttons are paired with input fields.
Small32 / 2Use when there is not enough vertical space for the default sized button.
