How to Reduce Shipping Costs with Lightweight Single Wall Boxes

Lighter boxes, lower shipping costs: how to optimise your box weight.

3 min readUpdated April 2025

Shipping cost savings

Lighter boxes reduce actual weight charges
Right-sizing reduces dimensional weight
Combined savings of 15-30% on typical shipping costs

Quick answer

Lighter board grades and right-sized boxes together save 15-30% on shipping. Use the lightest board grade that adequately protects your products. Right-size to minimise dimensional weight. E-flute (lightest) suits items under 5kg. B-flute (standard) for items up to 15kg. Every gram saved compounds across thousands of shipments. Calculate the total savings by multiplying per-shipment weight reduction by your shipping rate and volume.

Balancing weight and strength

Never reduce board weight below what protects your product. Test lighter grades with your actual items and stacking requirements. The lightest adequate specification is optimal: adequately strong but minimally heavy.
