Larger vessels, such as cargo vessels and tankers, can be further categorised into sub-categories based on their means of measuring their size.
The size-ranges, as mentioned in the table below, are used by MarineTraffic to further categorise the recorded vessels in Advanced Density Maps:
| VESSEL TYPE | SUB-CATEGORY | SIZE (in DWT) |
| CARGO VESSELS | HANDYSIZE | 0 - 39,999 |
| CARGO VESSELS | HANDYMAX | 40,000 - 59,999 |
| CARGO VESSELS | PANAMAX+ | 60,000 - 119,999 |
| CARGO VESSELS | CAPESIZE+ | > 120,000 |
| TANKERS | HANDYSIZE | 0 - 39,999 |
| TANKERS | HANDYMAX/PANAMAX/MR/LR1 | 40,000 - 79,999 |
| TANKERS | AFRAMAX - LR2 | > 80,000 |
| VESSEL TYPE | SUB-CATEGORY | SIZE (in TEU) |
| CONTAINER SHIPS | FEEDERS | 0 - 3,000 |
| CONTAINER SHIPS | LARGE | > 3,000 |
Note I: Keep in mind that the categorisation is not universal. You may come across slightly different size-ranges per Category.
