Master Dimensional Weight & Save on Every Shipment
📦 Did You Know?
Using a box just 2 inches too large in each dimension can increase your shipping costs by 40% or more due to dimensional weight pricing. Right-sizing your boxes is one of the fastest ways to improve your shipping margins.
How DIM Weight Works
Carriers charge based on whichever is greater: actual weight or dimensional weight. The formula:
Length × Width × Height ÷ 139 = DIM Weight
This means empty space in your box costs you money on every shipment.
Optimization Tips
- Measure your top 10 products and find ideal box sizes
- Leave only 2-3" total space for protective packaging
- Consider multiple box sizes vs. one-size-fits-all
- Track your actual vs. DIM weight charges monthly

Box Storage & Handling Best Practices
Proper storage and handling of your corrugated boxes ensures they maintain their strength and appearance when you need them. Follow these professional tips to maximize your investment:
📦 Warehouse Storage
Keep your boxes in prime condition:
- Climate control: Store in dry areas away from moisture
- Stack smart: Keep flat bundles on pallets or shelving
- Protect from sun: UV light can weaken corrugated material
- Label clearly: Mark bundles by size for easy identification
- Rotate stock: Use FIFO (First In, First Out) method
⚡ Assembly Efficiency
Speed up your packing process:
- Use box formers: Ensure consistent assembly every time
- Pre-fold strategy: Prepare boxes during slow periods
- Station setup: Keep boxes near packing areas
- Train your team: Proper H-taping seals boxes securely
- Quality tape: Use 2" or 3" wide packaging tape
💡 Pro Tip: Temperature Matters
Corrugated boxes perform best when stored between 60-80°F. Extreme temperatures can affect the adhesive bonds in the corrugation, reducing box strength by up to 20%.
Frequently Asked Questions
What is the minimum order quantity for corrugated boxes?
We have very low minimum order requirements. You can order as little as 1 bundle (typically 10-25 boxes depending on size) or as many pallets as you need. This flexibility is perfect for testing new sizes or managing seasonal inventory.
What does 32 ECT mean and is it strong enough for my products?
32 ECT (Edge Crush Test) measures the stacking strength of corrugated cardboard — specifically, how much force the edge of the board can withstand before it crushes. A 32 ECT box can handle 32 pounds of force per inch along the edge.
This is the industry standard for single-wall corrugated boxes and is suitable for most shipping needs, typically holding up to 30–65 lbs, depending on your packing method and product type. It’s ideal for e-commerce, retail packaging, and general shipping applications.
How can I reduce dimensional weight charges?
Choose boxes that leave only 2-3 inches of space around your product for protective packaging. Use our product table to compare DIM weights. Many customers save 20-40% on shipping by switching to properly sized boxes. We offer free consultation to help optimize your box selection.
Can I get custom printed boxes in small quantities?
Yes! We offer custom printing starting at just 250 boxes. Free design consultation is included with all custom orders.
How quickly do orders ship?
Stock boxes ship same or next business day from our Indiana warehouse. Most orders reach destinations within 2-3 business days. Custom printed boxes typically take 2-3 weeks depending on the printing method and order complexity.
Are your boxes made in the USA?
Yes, all our corrugated boxes are manufactured in the United States. We partner with domestic mills and converters to ensure consistent quality, support American jobs, and maintain reliable supply chains.
Do you offer samples before I place a large order?
Absolutely! We encourage testing boxes before committing to large quantities. Request up to 3 different sizes through our sample program. This helps ensure proper fit and confirms our quality meets your standards.
What's the difference between your boxes and those from big box stores?
Our boxes are certified 32 ECT, a commercial-grade standard for single-wall corrugated strength. Many retail store boxes may use lower-grade 32 ECT or 200# test.
We provide custom printing, bulk business pricing, and expert support — all with no membership fees or retail markups.
