# Global settings overview

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

## 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.
