Amazon FBA

Size tier

Small Bulky at the lightest. Amazon sets the tier on the greater of unit weight and dimensional weight — here 1,680 ÷ 139 = 12.09 lb. It isn’t Large standard because its shortest side 10 in is over 8 in; it fits Small Bulky (37 × 28 × 20 in, 130 in length + girth, 50 lb).

Heavier contents can move it up a tier — check with your product’s weight. See the FBA dimensional weight guide for 2026 fees.

USPS Flat Rate

Too big for every USPS Flat Rate box — the roomiest are the Large Flat Rate Box (12 × 11 3/4 × 5 1/2 in inside) and Medium Flat Rate Box 2 (13 5/8 × 11 7/8 × 3 3/8 in inside).

FAQ

14x12x10 box questions

How many cubic feet is a 14x12x10 box?
14 × 12 × 10 = 1,680 cubic inches. Divide by 1,728 (cubic inches per cubic foot) and you get 0.972 cubic feet — 27.5 liters or 7.27 US gallons. These are the box’s own dimensions; if they’re inside dimensions, the outside (what carriers measure) is slightly larger.
What is the dimensional weight of a 14x12x10 box?
13 lb at FedEx, UPS (Daily Rates) and DHL Express from the US, which divide 1,680 in³ by 139 and round up; 11 lb at UPS Retail Rates (÷ 166). USPS doesn’t apply dimensional weight: at 1,680 in³ the box is not over 1 ft³ (1,728 in³), so Priority Mail and Ground Advantage price it on actual weight. You pay whichever is greater, the actual weight or the dimensional weight.
Does a 14x12x10 box get oversize or Additional Handling fees?
Not for its size at UPS or FedEx: longest side 14 in (line: 48 in), second-longest 12 in (30 in), length + girth 58 in (105 in) and 1,680 in³ (10,368 in³) are all inside the Additional Handling lines. Weight over 50 lb still triggers Additional Handling. USPS: no nonstandard fee for this size.
How many 14x12x10 boxes fit on a pallet?
9 per layer on a 48 × 40 in pallet with the 10 in side standing up (3 × 3), and 6 layers in 60 in of stack height — 54 boxes. The layer covers 79% of the deck. Interlocked or mixed patterns can sometimes fit more.
What Amazon FBA size tier is a 14x12x10 box?
Small Bulky at the lightest — Amazon uses the greater of unit weight and dimensional weight (12.09 lb for this box, 1,680 ÷ 139) to set the tier. It isn’t Large standard because its shortest side 10 in is over 8 in; it fits Small Bulky (37 × 28 × 20 in, 130 in length + girth, 50 lb).
