What fits in a 10×6×4 box
A 10 × 6 × 4 inch box holds 240 cubic inches (0.14 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 10×6×4 box, UPS and FedEx Ground compute a DIM weight of 2 lbs using their 139 divisor, while USPS Ground Advantage uses a 166 divisor, giving 2 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 10×6×4 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 **landed cost per box** — the pack price plus shipping, divided by the number of boxes. A 100-pack with $10 shipping works out cheaper per box than a 25-pack with the same shipping, because the fixed cost spreads further. Every listing below links to a real product page from eBay, ULINE, or other retailers; we don't show placeholder results.
