Getting strength and size right
The two decisions that make or break a shipping box are the corrugated strength and the size. Get them right and your product arrives safely at a low shipping cost. This guide explains both.
Corrugated strength
Corrugated board has fluted layers between liners, and the flute grade and wall count determine strength. Single wall suits most light to medium products, while double wall adds protection for heavy or fragile items and better stacking strength. Heavier products, fragile items, and long transit all point to a stronger grade. Our team matches the grade to your product so it is protected without overpaying for more board than you need.
Sizing
Measure your product at its longest, widest, and tallest points, and allow room for any protection or void fill. The internal box dimensions should fit the product snugly so it does not shift, without leaving wasted space that raises dimensional weight. If you ship multiple items together, size for them packed as they will ship.
Balancing protection and cost
The goal is enough strength and a snug size to protect the product, without paying for more board or more box than you need. Right sizing lowers both material and shipping cost, and the right grade prevents damage and returns. Our team helps you strike the balance.
Frequently asked questions
What is double wall corrugated? Two fluted layers for extra strength, used for heavy or fragile products.
How much extra space should I leave? Enough for protection or void fill without oversizing. We help you size it.
Does box size affect shipping cost? Yes, through dimensional weight. Right sizing lowers cost.
