16 × 10 × 8 in box: dimensions, dim weight and strength
A 16 × 10 × 8 in box holds 1,280 in³ (0.74 ft³) inside. Made in C flute its outside is about 16.31 × 10.31 × 8.47 in, which dimensional weight bills USPS at actual weight (under its threshold) and FedEx at 10 lb.
Key numbers
| Inside (L × W × H) | 16 × 10 × 8 in |
|---|---|
| Inside volume | 1,280 in³ · 0.741 ft³ · 21 L |
| Inside, metric | 406 × 254 × 203 mm |
| Perimeter 2(L + W) | 52 in |
| Length + girth, C flute OD | 53.9 in |
Outside dimensions by flute
| Board | Caliper, in | Outside, in | Outside volume, ft³ |
|---|---|---|---|
| E flute | 0.063 | 16.13 × 10.13 × 8.19 | 0.774 |
| B flute | 0.125 | 16.25 × 10.25 × 8.38 | 0.807 |
| C flute | 0.156 | 16.31 × 10.31 × 8.47 | 0.824 |
| EB double wall | 0.188 | 16.38 × 10.38 × 8.56 | 0.842 |
| BC double wall | 0.281 | 16.56 × 10.56 × 8.84 | 0.895 |
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 × 11 × 9 | n/a | n/a |
| FedEx | 139 | 16 × 10 × 8 | 10 lb | 13 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 | 479 | 287 |
| 32 ECT C flute | 535 | 321 |
| 44 ECT C flute | 736 | 442 |
| 48 ECT C flute | 803 | 482 |
| 48 ECT BC double wall | 1,078 | 647 |
| 61 ECT BC double wall | 1,369 | 822 |
| 71 ECT BC double wall | 1,594 | 956 |
Simplified McKee: BCT ≈ 5.87 × ECT × √(caliper × 52). 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 | 9 | 6 | 54 | 56.3 | 74% |
| BC double wall | 8 | 6 | 48 | 58.6 | 71% |
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 (1 rows turned).
Blank size in C flute
| Style | Blank, in | Board, ft² |
|---|---|---|
| 0201 RSC | 53.88 × 18.31 | 6.85 |
| 0200 HSC | 53.88 × 13.16 | 4.92 |
| 0203 FOL | 53.88 × 28.31 | 10.59 |
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.
