**Choosing the metafield (version 1.3.0)**

The **Model size block** reads this content through its **Model size metafield** setting. The default key is `custom.model_size`.

* Keep the default key above and it works with no extra setup.
* Or rename it: create the metafield under your own `namespace.key` (for example, your brand name), then set **Model size metafield** to match.
* Reuse on one page: create one metafield per copy (for example `custom.model_size` and `custom.model_size_2`) and point each **Model size metafield** at its own key to show different content.

See [How to setup Metafield in version 1.3.0?](/purity-theme/theme-installation/create-required-metafields/how-to-setup-metafield-in-version-1.3.0.md) for details.
