16 × 12 × 10 in box: dimensions, dim weight and strength
A 16 × 12 × 10 in box holds 1,920 in³ (1.11 ft³) inside. Made in C flute its outside is about 16.31 × 12.31 × 10.47 in, which dimensional weight bills USPS at 18 lb and FedEx at 14 lb.
Key numbers
| Inside (L × W × H) | 16 × 12 × 10 in |
|---|---|
| Inside volume | 1,920 in³ · 1.111 ft³ · 31.5 L |
| Inside, metric | 406 × 305 × 254 mm |
| Perimeter 2(L + W) | 56 in |
| Length + girth, C flute OD | 61.9 in |
Outside dimensions by flute
| Board | Caliper, in | Outside, in | Outside volume, ft³ |
|---|---|---|---|
| E flute | 0.063 | 16.13 × 12.13 × 10.19 | 1.153 |
| B flute | 0.125 | 16.25 × 12.25 × 10.38 | 1.195 |
| C flute | 0.156 | 16.31 × 12.31 × 10.47 | 1.217 |
| EB double wall | 0.188 | 16.38 × 12.38 × 10.56 | 1.239 |
| BC double wall | 0.281 | 16.56 × 12.56 × 10.84 | 1.306 |
OD ≈ ID + 2 calipers on length and width, + 3 on depth. An estimate: your box maker sets the scores. Convert other sizes.
Dimensional weight
| Carrier | Divisor | Measured, in (C) | DW, C flute | DW, BC double wall |
|---|---|---|---|---|
| USPS | 139 | 17 × 13 × 11 | 18 lb | 18 lb |
| FedEx | 139 | 16 × 12 × 10 | 14 lb | 18 lb |
DW = ⌈L × W × H ÷ divisor⌉ on outside dimensions, after each carrier's own rounding. USPS applies it only above 1,728 in³ (n/a means it bills actual weight). The carrier bills the greater of actual and dimensional weight. Divisors checked on carrier pages 2026-10-27; try your own weight.
Estimated compression strength
| Board | BCT, lbf | After 30 days storage |
|---|---|---|
| 32 ECT B flute | 497 | 298 |
| 32 ECT C flute | 556 | 333 |
| 44 ECT C flute | 764 | 458 |
| 48 ECT C flute | 833 | 500 |
| 48 ECT BC double wall | 1,118 | 671 |
| 61 ECT BC double wall | 1,421 | 853 |
| 71 ECT BC double wall | 1,654 | 992 |
Simplified McKee: BCT ≈ 5.87 × ECT × √(caliper × 56). The 30-day column applies Packgent's default 40% storage loss, an assumption. Estimates only; test with ASTM D642.
Pallet pattern on 48 × 40
| Board | Per layer | Layers | Boxes per pallet | Load height, in | Cube used |
|---|---|---|---|---|---|
| C flute | 8 | 5 | 40 | 57.8 | 80% |
| BC double wall | 8 | 5 | 40 | 59.7 | 86% |
Column stacked, no overhang, on a 48 × 40 in deck 5.5 in tall, loaded to 60 in overall. Those three are assumptions you can change in the pallet calculator. Pattern: two-zone (2 rows turned).
Blank size in C flute
| Style | Blank, in | Board, ft² |
|---|---|---|
| 0201 RSC | 57.88 × 22.31 | 8.97 |
| 0200 HSC | 57.88 × 16.16 | 6.49 |
| 0203 FOL | 57.88 × 34.31 | 13.79 |
With one caliper allowance per score. Multiply board area by your board's combined weight (lb/MSF ÷ 1,000) for box weight, or use the box weight calculator.
