17 × 17 × 17 in box: dimensions, dim weight and strength
A 17 × 17 × 17 in box holds 4,913 in³ (2.84 ft³) inside. Made in C flute its outside is about 17.31 × 17.31 × 17.47 in, which dimensional weight bills USPS at 42 lb and FedEx at 36 lb.
Key numbers
| Inside (L × W × H) | 17 × 17 × 17 in |
|---|---|
| Inside volume | 4,913 in³ · 2.843 ft³ · 80.5 L |
| Inside, metric | 432 × 432 × 432 mm |
| Perimeter 2(L + W) | 68 in |
| Length + girth, C flute OD | 86.9 in |
Outside dimensions by flute
| Board | Caliper, in | Outside, in | Outside volume, ft³ |
|---|---|---|---|
| E flute | 0.063 | 17.13 × 17.13 × 17.19 | 2.917 |
| B flute | 0.125 | 17.25 × 17.25 × 17.38 | 2.992 |
| C flute | 0.156 | 17.31 × 17.31 × 17.47 | 3.03 |
| EB double wall | 0.188 | 17.38 × 17.38 × 17.56 | 3.068 |
| BC double wall | 0.281 | 17.56 × 17.56 × 17.84 | 3.185 |
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 | 18 × 18 × 18 | 42 lb | 42 lb |
| FedEx | 139 | 17 × 17 × 17 | 36 lb | 42 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 | 548 | 329 |
| 32 ECT C flute | 612 | 367 |
| 44 ECT C flute | 842 | 505 |
| 48 ECT C flute | 918 | 551 |
| 48 ECT BC double wall | 1,232 | 739 |
| 61 ECT BC double wall | 1,566 | 940 |
| 71 ECT BC double wall | 1,823 | 1,094 |
Simplified McKee: BCT ≈ 5.87 × ECT × √(caliper × 68). 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 | 4 | 3 | 12 | 57.9 | 60% |
| BC double wall | 4 | 3 | 12 | 59 | 63% |
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: 17.3125″ along the 48″ side.
Blank size in C flute
| Style | Blank, in | Board, ft² |
|---|---|---|
| 0201 RSC | 69.88 × 34.31 | 16.65 |
| 0200 HSC | 69.88 × 25.66 | 12.45 |
| 0203 FOL | 69.88 × 51.31 | 24.9 |
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.
