Smarter Packing. Accurate Rates. No Surprises.

Say goodbye to one-size-fits-all shipping rates. ShipperHQ’s Dimensional Packing simulates how you actually pack, so you can show the right rates at checkout and control shipping costs.

Eating shipping costs? ShipperHQ fixes that.

If you’re shipping large orders, bulky products, or items of various sizes – and your setup relies on flat rates or basic shipping calculations – you’re either losing money or overcharging customers.

How It Works

Right-Sized Boxes, Right-Sized Shipping Costs

Get started in 3 easy steps:

1. Enable Feature
   Automatically rate each cart based on available packing information—including max weights by carrier and product dimensions.
2. Add Packing Rules & Boxes
   Define how items pack and which boxes you use. Go as detailed or simple as you need to keep shipping costs in check.
3. Automate and Save
   Display accurate rates at checkout, then pass the details back to your platform—saving you time and money.

Your Checkout. Your Packing Rules.

No two warehouses pack alike. ShipperHQ lets you take full control of how products get boxed and rated at checkout — so your shipping math actually adds up.

• Define box types with dimensions, weight limits, or quantity caps that reflect your real packaging inventory.
• Account for items that ship separately, ship in multiple boxes, or ship in fixed-quantity master cases.
• Assign boxes and rules by product, carrier, or SKU – no developer required.
• Add packing material weight and shipping surcharges to your box details.

Pack Smarter. Spend Less.

Every inch in a box costs you money. ShipperHQ’s best-fit algorithm finds the most efficient way to pack orders so you can keep rates competitive and cut shipping costs.

• Reviews product dimensions, weight, quantity, box sizes, and packing rules to determine the most efficient configuration.
• Packs items into the fewest, smallest boxes possible to minimize dimensional weight charges.
• Prevents overcharges and undercharges that hurt margins or drive customers away.
• Cuts costs and reduces waste by feeding packing data for each order into your ecommerce platform – improving how your team fulfills in real life.

Handle Any Cart, No Matter How Complex

Whether you’re shipping kayaks or cutting boards, ShipperHQ ensures your calculated rates reflect the true cost of shipping –  keeping your business profitable without hurting conversions.

• Support any shipping scenario — Ship parcel, LTL freight, and mixed carts.
• Deliver accurate rates for large, bulky, and multi-item orders — just like you do for small, single-SKU shipments.

• Use live, negotiated, or custom carrier rates — and test them directly in ShipperHQ to verify before going live.

FAQs

Can I use dimensional packing if I don’t have all my product dimensions or box sizes yet?

Yes. ShipperHQ’s dimensional packing helps improve shipping rate accuracy even if you haven’t added all your product dimensions or box sizes yet. It uses carrier shipment limits, such as maximum weight per box, to calculate more accurate rates from the start.

How can I get accurate shipping rates using dimensional weight in my online store?

To get accurate rates, you need to factor in both the size and weight of each shipment. ShipperHQ applies dimensional weight logic at checkout by using product dimensions, box sizes, and carrier rules in real time.

Which types of products typically require dimensional packing for accurate rates?

Dimensional packing is especially useful for products that are large, bulky, or take up more space than their weight suggests. Carriers often charge for these items based on volumetric weight, not just actual weight.

Does dimensional packing work if I’m using table rate shipping?

Yes. ShipperHQ’s dimensional packing feature calculates dimensional weight first, then applies your table rates.

What packing rule options are available in ShipperHQ?

ShipperHQ gives you full control over how items are packed with flexible configuration options, including:

• Largest Packing Algorithm: Automatically selects the largest available box for oversized items
• Pack Separately: Packs each item in its own box
• Master Packing Box: Uses a pre-packed box that ships on its own
• Ship SKUs Separately: Ensures each box contains only one SKU
• Pack in multiple fixed boxes: Splits a single SKU into set packages

What impact does dimensional weight have on the pricing of a shipment?

Dimensional weight impacts how carriers price large or lightweight shipments. If dimensional weight is higher than the actual weight, carriers charge based on size, not the dead weight.
