Dimensional Packing: Configure Boxes to be Used for All Products

Learn how to assign products to the right boxes in ShipperHQ for accurate dimensional weight calculations and better shipping decisions.

 

Table of Contents

Overview

Dimensional packing helps you ship more efficiently by rating packages based on size and space, not just dead weight.

When you assign products to specific boxes or let ShipperHQ pick automatically, you save money, prevent overcharges, and improve rating accuracy at checkout.

This guide explains how to set up product-to-box assignments so your dimensional weight calculations always reflect how you actually ship.

Setup

You can configure product-to-box assignments in two main ways:

  1. Let all products pack into any available box.

  2. Assign certain products to specific boxes while keeping flexibility for everything else.

Option 1: Pack All Products Into Any Available Box

This option gives ShipperHQ the freedom to choose the best box based on product size and volumetric weight.

How to enable this:

  • Manually: Edit each box and check "Can Be Used to Pack All Products".

  • Using CSV:

    1. Export your boxes as a CSV file.

    2. Set the "All Products" column to Yes.

    3. Re-import the updated file into ShipperHQ.

💡 Why this helps:

This setup works well if most of your products can ship in any box. It allows ShipperHQ to select the smallest and most efficient box for each order.

Option 2: Pack Assigned Products in Specific Boxes and Others in Any Box

Some products need special boxes because of their size, shape, or fragility. You can create packing rules to control which boxes are used for those items while keeping flexibility for everything else.

Create a rule for your specific products & boxes

  • Set up the desired boxes for specific products and ensure "Can Be Used to Pack All Products" is unchecked or set to "No."

  • Go to Packing rules, create and name a rule according to the product types you wish to pack using the boxes created.

    • Select "Pack According to Box Rules" for the Method of Packing.
    • Under "Possible Boxes," add your newly created boxes.
    • Assign this rule to the desired product(s) in your eCommerce platform settings. See Magento example for more details.

Create a rule for all other products (optional)

  • Create a packing rule named "All Products" or another descriptive name.
    • Choose "Pack According to Box Rules" for the Method of Packing.
    • Leave "Possible Shipping Boxes" blank to utilize default boxes that are set to "Yes" or "Can Be Used to Pack All".

    • Opt to "Default This Rule for All Products" from Optional settings.

💡 Why this helps:

This setup gives you control over how unique products are packed while still allowing automation for everything else. It combines accuracy with flexibility.

What Product-to-Box Assignments Do

Setting up the right product-to-box Packing rules help you to:

  • Improve dimensional weight accuracy.

  • Avoid extra charges caused by oversized packaging.

  • Ensure fragile or large items always ship in the right boxes.

  • Keep your shipping rates consistent helping you convert more carts.
