E-commerce Box Optimization: Stop Wasting Money on Oversized Boxes
Find the perfect box size for every order - reduce costs like Amazon and major retailers
The Hidden Cost of Wrong-Sized Boxes
Every inch of empty space in your shipping boxes represents a direct hit to your bottom line. From wasted materials to inflated shipping fees, the cost of inefficient packaging adds up. Our AI-powered tool eliminates this waste by instantly identifying the smallest viable box for any combination of items, mirroring the sophisticated optimization systems of e-commerce giants. This is a game-changer for:
- E-commerce Stores: Dramatically reduce box inventory and outbound shipping costs.
- Amazon FBA Sellers: Minimize costly dimensional weight (DIM) charges and improve margins.
- 3PLs & Fulfillment Centers: Streamline pick-and-pack operations and increase throughput.
- Subscription Box Companies: Standardize packaging to improve cost efficiency and customer experience.
- Box Costs: Up to $2.00 per shipment on needlessly oversized boxes.
- Void Fill: An extra $0.50 per package just to fill empty air with packing peanuts or pillows.
- DIM Weight Penalties: Paying up to 40% more in carrier fees for bulky, half-empty packages.
- Wasted Labor: 30+ seconds of packer guesswork on every single order.
E-commerce Box Selection Example
Imagine a common scenario: an order comes in, and your packer has to choose from your standard box inventory. Which one is the right fit?
Find the best one:
- 12 x 9 x 6 (small box)
- 16 x 12 x 8 (medium box)
- 20 x 16 x 12 (large box)
Customer ordered:
2 items of 5 x 4 x 3
3 items of 3 x 3 x 2

Empower your warehouse team to make the right choice every time. Instead of defaulting to a larger, "safe" option, our system provides an instant, data-backed decision that cuts material costs and slashes dimensional weight fees.
Custom Box Size Recommendation
What if you don't have a perfect-fit box? Our tool helps you design a better inventory. By analyzing a typical order, it can recommend the ideal custom box size to stock.
Customer order:
1 laptop 15 x 10 x 1
1 charger 4 x 3 x 2
1 mouse 5 x 3 x 1.5
find the best container with minimum width and length?

Leverage this insight to refine your packaging supply. By stocking box sizes that are mathematically aligned with your most frequent order combinations, you can systematically reduce costs across your entire operation.
Subscription Box Optimization
For subscription box companies, consistency and efficiency are paramount. How do you choose a standard box size that maximizes the number of products you can include?
Monthly beauty box items:
- 5 x 5 x 6 (standard box)
- 4 x 5 x 5 (eco box)
max quantity of products 2 x 1 x 3?

This is the ideal tool for balancing product value, unboxing experience, and packaging costs, ensuring your subscription service remains profitable and competitive.
How It Works
Our system is designed for ease of use. It processes simple, natural language queries to solve complex packing problems, considering:
- Advanced 3D packing algorithms that test thousands of potential orientations.
- All possible item rotations (on length, width, and height) to find the tightest fit.
- A primary focus on maximizing container volume efficiency to reduce empty space.
- Real-world constraints to ensure the suggested pack is physically possible to load.
Just type what you need:
- "Find the best container" to instantly compare your stock boxes and get the most cost-effective recommendation.
- "Max quantity" to determine exactly how many of a single SKU can fit into a specific box.
- "Find the best one: [list]" to compare a specific list of boxes and see which is the optimal choice for an order.
- "[items], find the best container?" to discover the minimum box dimensions needed for a multi-item order, perfect for sourcing new packaging.
Real Business Impact

- Boost Efficiency: Free up hours of manual guesswork for your packing team.
- Increase Accuracy: Eradicate costly errors from packers choosing the wrong box size.
