> Step-by-step guide to setting up product dimensions in Magento 2.

You can add product dimensions to Magento 2, which Starshipit then reads on import and uses for rates at checkout. Magento 2 uses an attribute system to manage product information like size and colour. To use dimensions in Starshipit you'll need to create custom attributes in your Magento 2 settings.

## How it works

To start, you will need to create the following custom attributes in Magento 2:

* Length
* Height
* Width

Note: Ensure you follow the exact spelling. Capitalisation (Length vs length) doesn’t matter.

## Add a custom attribute in Magento 2

1. Go to the **Admin Panel**.
2. Click **Stores**.
3. Click **Attributes**.
4. Click **Product**.
5. Click **Add Attribute**.
6. Click **Create New Attribute**.
7. Set the name of the attribute in the field **Attribute Label** as **Length**.
8. Leave the Catalog input Type as "Text Field".
9. You don't need to change the **Required** toggle.
10. Click **Save Attribute**.

Repeat the above steps to create attributes for **Height** and **Width.**

## Notes

* All custom attributes created for one product will be created for all products as empty fields. If the fields are empty or if you set a non-numeric character in the dimension, then it will assume zero when getting rates.
* Once the attributes are created, it will start working next time a customer adds this product to their shopping cart.
* If your dimensions aren’t pulling through, change the attribute code to all lower case.
* When importing orders from Magento 2, the dimensions come through to Starshipit in meters (m).
* When you open an order, you’ll see the imported dimension converted according to the Display Sizes Unit you’ve set in Settings > Options.
