Box Guide

Use this guide to determine which box is right for you.

What is the difference between 200 lb. test and 32 ECT boxes?

Stop costly returns due to shipping damage. Cheaper boxes may not survive the hazards of everyday shipping and handling.

Uline and UPS recommend 200 lb. test boxes, which provide more strength and protection than 32 ECT boxes – a budget-friendly alternative for lightweight shipments.
Uline 200 lb. test boxes are made with heavier paper and have 60% greater bursting strength than 32 ECT boxes.
Greater bursting strength means fewer crushed and damaged boxes during shipping.
Uline refuses to sacrifice the quality of our boxes.

How to Measure a Box

Listed dimensions are always inside dimensions.
The first dimension is length. Length is always the longest side of the box that has a flap.
The next dimension is width. The width side also has a flap but is always the side shorter than the length.
Height is the only dimension without a flap. Height measurements do not include flaps.

NOTE: Acceptable manufacturing variance is +/- 1/8".
