The two description fields serve different purposes:
- The first "Short description" field enables you to write a short description that will appear in search engines and in the category description for your product.
This field is limited to 400 characters by default: if you exceed that limit, PrestaShop will warn you with a message in red below the field. The second You can change that limit in the "Products" preference page, where you will find the "Max size of short description" option. - The "Description" field enables you to write a full description of your product, which will appear directly on the product page. The text editor offers a wide range of options for creating visually attractive descriptions (font, size, text color, etc.).
