What fits in a 8×8×8 box
A 8 × 8 × 8 inch box holds 512 cubic inches (0.30 cu ft) of interior space, putting it in the medium-cube category. It's a popular choice for shipping items like coffee mugs, glassware, small ceramic items — things that fit comfortably within those dimensions while leaving room for protective padding. Bulk packs of 25, 50, and 100 are the common listing sizes, with per-unit pricing typically between $0.60 and $2.00 depending on quantity and seller.
Shipping math for this size
Shipping cost for this size depends heavily on dimensional weight. For a 8×8×8 box, UPS and FedEx Ground compute a DIM weight of 4 lbs using their 139 divisor, while USPS Ground Advantage uses a 166 divisor, giving 4 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.
How to pick the right pack size
When buying a 8×8×8 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.
