What fits in a 6×4×2 box

A 6 × 4 × 2 inch box holds 48 cubic inches (0.03 cu ft) of interior space, putting it in the small-category. It's a popular choice for shipping items like small electronics, jewelry boxes, phone cases — things that fit comfortably within those dimensions while leaving room for protective padding. Most sellers list it in bulk packs of 25, 50, or 100, which brings the per-box cost under $1 for the cheapest options.

Shipping math for this size

Shipping cost for this size depends heavily on dimensional weight. For a 6×4×2 box, UPS and FedEx Ground compute a DIM weight of 1 lbs using their 139 divisor, while USPS Ground Advantage uses a 166 divisor, giving 1 lbs. Carriers bill whichever is greater — your actual weight or the DIM weight. The two carriers come out about the same for this volume, which is why our search results factor in DIM-weight automatically instead of just showing sticker prices. For very light items, a USPS Priority Flat Rate envelope or small box may beat buying this size outright — we flag that when it applies.

How to pick the right pack size

When buying a 6×4×2 box, the biggest cost lever isn't which retailer you pick — it's which pack size you commit to. A 100-pack typically costs 2-3× more than a 25-pack but brings the per-unit cost down by 40-60%. Our ranking is based on *cost per useful box*, which gives bonus boxes partial credit — so a 100-pack can still win for single-box needs if the per-unit price is low enough, but a 25-pack often ranks higher when you only need a few. Every listing below links to a real eBay product page; we don't show placeholder results.
