Overview

Medium shipping boxes — 13" to 17" on the longest side, the workhorse range for multi-item orders, subscription packs, and standard moving cartons. Bundle quantities with per-box pricing shown, shipped from 5 US regional warehouses.

How to choose: this is the range where dimensional weight starts to matter — a 16x16x16 at ECT-32 handles most household and e-commerce loads, while denser contents deserve the heavy duty grades. Packing mixed items? Cube sizes stack better; shallow cartons protect flat goods. Size up or down at the size chart.

Frequently asked questions

What is the most common medium moving box size?
16x16x16 is the standard "medium" moving carton across the industry — big enough for kitchenware and books in mixed loads, small enough to lift safely when packed. In this range it ships economically by parcel or pallet.

Are medium boxes cheaper per box in bulk?
Yes — every listing here is bundle-priced, and the per-box price falls as case counts rise. The per-box math is printed on each product page so quantities compare honestly.

What to check first
