22 × 22 × 22 in box: dimensions, dim weight and strength
A 22 × 22 × 22 in box holds 10,648 in³ (6.16 ft³) inside. Made in C flute its outside is about 22.31 × 22.31 × 22.47 in, which dimensional weight bills USPS at 88 lb and FedEx at 77 lb.
Key numbers
| Inside (L × W × H) | 22 × 22 × 22 in |
|---|---|
| Inside volume | 10,648 in³ · 6.162 ft³ · 174.5 L |
| Inside, metric | 559 × 559 × 559 mm |
| Perimeter 2(L + W) | 88 in |
| Length + girth, C flute OD | 111.9 in |
Outside dimensions by flute
| Board | Caliper, in | Outside, in | Outside volume, ft³ |
|---|---|---|---|
| E flute | 0.063 | 22.13 × 22.13 × 22.19 | 6.285 |
| B flute | 0.125 | 22.25 × 22.25 × 22.38 | 6.41 |
| C flute | 0.156 | 22.31 × 22.31 × 22.47 | 6.473 |
| EB double wall | 0.188 | 22.38 × 22.38 × 22.56 | 6.537 |
| BC double wall | 0.281 | 22.56 × 22.56 × 22.84 | 6.73 |
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 | 23 × 23 × 23 | 88 lb | 88 lb |
| FedEx | 139 | 22 × 22 × 22 | 77 lb | 88 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 | 623 | 374 |
| 32 ECT C flute | 697 | 418 |
| 44 ECT C flute | 958 | 575 |
| 48 ECT C flute | 1,045 | 627 |
| 48 ECT BC double wall | 1,402 | 841 |
| 61 ECT BC double wall | 1,782 | 1,069 |
| 71 ECT BC double wall | 2,074 | 1,244 |
Simplified McKee: BCT ≈ 5.87 × ECT × √(caliper × 88). 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 | 2 | 2 | 4 | 50.4 | 43% |
| BC double wall | 2 | 2 | 4 | 51.2 | 44% |
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: 22.3125″ along the 48″ side.
Blank size in C flute
| Style | Blank, in | Board, ft² |
|---|---|---|
| 0201 RSC | 89.88 × 44.31 | 27.66 |
| 0200 HSC | 89.88 × 33.16 | 20.69 |
| 0203 FOL | 89.88 × 66.31 | 41.39 |
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.
