Size popup
| Setting | Description |
| Size option name |
Enter the name(s) of variant options that should trigger the size popup. You can add multiple names separated by commas (e.g., Size, Shoe Size, Length). If your products use different option names for sizing (for example, Size on some products and Shoe Size on others), include each name here so they will be displayed in the size popup. This is useful if your store sells different product types, such as clothing and shoes. |

After closing the popup, the selected size will automatically be applied on the product page, allowing you to add the item to the cart without any extra steps. |

Size conversion
This section with options is displayed when size popup type is set to Size select popup
| Setting | Description |
| Enable size conversion |
Show EU, US and UK sizes. Automatically detects size system (EU/US/UK) and converts accordingly. Note: If this option is disabled, only the size format entered on the product page in the Dashboard will be displayed. |
| Custom size type | You can create a custom table to display sizes correctly in the popup. |
| Custom size conversion rules | JSON format for custom size conversions. Works for both shoes and clothing. Example: {"36": {"US": "5", "UK": "3.5"}, "S": {"US": "S", "UK": "8"}} |
To ensure size values display correctly, you need to select sizes consistently for all products on the product page in the Variants section.
For example, if you choose a US size for one product, it should be US everywhere; if UK, then UK everywhere; the same applies to EU, so that the table displays correctly.
By default, the custom table is set with US as the primary size. So if you enter US sizes for all products, the table will display correctly.
If, for example, you enter EU, you need to adjust the JSON format for custom size conversions so that the primary size matches the one you selected on the product page.
Example for US:
{ "4": {"US": "4", "EU": "35", "UK": "2.5"}, "4.5": {"US": "4.5", "EU": "35.5", "UK": "3"} }
Example for EU:
{ "35": {"US": "4", "EU": "35", "UK": "2.5"}, "35.5": {"US": "4.5", "EU": "35.5", "UK": "3"} }
It’s best to edit the table with GPT.
If you need to change the primary size in the syntax, you can write: “make EU the primary size without changing the syntax”, or create your own sizes following the format shown in Custom size conversion rules.
The way you add sizes on the product page determines how they appear. If you choose a US size format, it will be displayed in the product information block on the product template. This means you will see US in the variant options on the page, while the size table will show sizes in all three formats: EU, US, and UK.
