Global settings overview

Global Settings control behaviors and appearance that apply across your whole store, no matter which display type a product uses.

The page is organized into five groups:

Group	Covers
Swatch state	Out-of-stock display, Non-existent display, strike-through direction/color, Two-color swatch split
Variant selection behaviour	Variant preselection, Add-to-cart error message, dropdown placeholder, Hide single variant, Collection page click behaviour, Tooltip
Automatic badges	Sold out, Low stock, New, and On sale badges, based on store-wide rules
Position and images	Image swatch size
Advanced	Custom CSS

Image swatch size

Image swatches are rendered at a fixed size (default 450 x 450 px, adjustable from 20 to 1200). If you increase the swatch display size but swatches look blurry, raise this value so the source image is sharp.

See Why is my image swatch blurry, and how can I fix it? for details.

Remember to click Save after changing any global setting.
