Dimensional Rules Configuration


This article will show you how to use Dimensional Rules whether you’re packing your boxes according to box rules or packing your items separately, the steps are below.

Steps: Pack According to Box Rules

1. To enable Dimensional Rules in your store, you need to enable the Dimensional Rules advanced feature from your Features page in ShipperHQ.

2. From the ShipperHQ Dashboard, navigate to the Dimensional Rules page and create a new dimensional rule by clicking “Add New”.

3. Give this Rule a Name. We will use “Journal Boxes” for this example.

4. For the sake of this tutorial we will leave the method of shipping field set to “Pack according to box rules”.

5. Scroll to Possible Shipping Boxes area of the page and click the Possible boxes dropdown area.Screen Shot 2016-05-12 at 11.51.46 AM

From here you have two options:

1. Create boxes from this area to be assigned to the rule

2. Use boxes you have already defined in the Box definitions area of ShipperHQ. (Note: they must not be “Assigned to all products if you want to select them on your dimensional rule) Also, keep in mind that this behavior works when set to Pack separately as well.

After possible boxes have been selected, just save the rule to apply changes.

Optional – Default Rule for all Products

If you want to have a rule that applies if no other rules are assigned then you can set this checkbox.

Optional – Set Dimensions

If all of the products this rule will apply to share the same dimensions, you can set them in the rule itself rather than having to keep re-entering them on your eCommerce platform. You’ll find this option under “Item Dimensions”. If you leave this section blank, ShipperHQ will use the dimensions you set on the product on your eCommerce platform.

Steps: Pack Separately

ShipperHQ allows you to cover this configuration by the use of Dimensional Rules. You can add this via the ShipperHQ dashboard.

Before creating your Ship Separately Dimensional Rule you’ll need to define the box in which your product will ship.  You can optionally not have a box set, in which case it will ship separate using weight alone, or if dimensions are set on the product will use those for the box size.

  1. When you create a Dimensional Rule you can select that it will ship separately using the “Method of Shipping” dropdown field.
  2. Optional select the packing Box

Setting the Dimensional Rule Group on your Products

Magento: In your eCommerce platform synchronise with ShipperHQ and select/enter the dimensional rule group at the product level.

BigCommerce: For all products that require this rule to be applied put the name of the dimensional rule against the product.


Whenever a product is in a cart with a ship separate rule associated it will pack each item (1 at a time) into a separate box as defined by the rule.

Shipping All Items Separately

You can optionally set to ship all items in their own box.  This is configured under Settings button on the Dimensional Rules tab.

Ship All Separately


Ship Separately on Magento

In Magento there is an attribute for “Ship separately”, which is an option in addition to the above options. This is ideal for customers migrating from the WebShopApps standalone Dimensional Shipping extension as the attribute is identical so they allow for a transition to ShipperHQ without needing to update products’ attributes. With this setting enabled, each quantity of the SKU will be shipped in its own box.


For these examples we will use a product with dimensions 2x2x2 and two boxes: one with dimensions of 4x4x4 and the other with dimensions 6x6x6.

Pack Items Separately

For this example a dimensional rule has been created with the packing mechanism set to “Pack separately” with the 6x6x6 box selected as the “Packing box for product” and this rule is assigned to the product.

Each quantity increment of the SKU will be packed into a 6x6x6 box. So, a quantity of two will pack in two 6x6x6 boxes and so on.

Ship All Products Separately

For this example the “All Items Ship Separately” option has been set to “Yes” in the dimensional rules. No boxes have been assigned to the product.

Each quantity increment of the SKU will be packed into a 2x2x2 box.

If both the 4x4x4 and 6x6x6 boxes are assigned to the product as possible boxes each quantity increment of the SKU will be packed into a 4x4x4 box.

Ship Separately Attribute

For this example, “Ship separately” has been selected within Magento. No boxes have been assigned to the product.

Each quantity increment of the SKU will be packed into a 2x2x2 box.

If the 4x4x4 box is assigned to the product as a possible box each quantity increment of the SKU will be packed into a 4x4x4 box.

Final Step (For Big Commerce)

Last thing you need to do in your eCommerce platform is assign this Dimensional Rule Group name to your product. Remember we used “Journal Boxes” for our example.

Save this change here and now this product will use only those boxes specified in the dimensional rule.
