“Short bus” is an informal label, so it does not identify one fixed length or passenger count. Micro Bird’s T-Series Type A school bus specifications show how the footprint changes by model:
| Micro Bird T-Series model | Overall length | Approx. length | Overall width | Maximum passenger capacity |
|---|---|---|---|---|
| 4N | 233 in | 19 ft 5 in | 86 in | 19 |
| 5N | 253 in | 21 ft 1 in | 86 in | 24 |
| 6N | 274 in | 22 ft 10 in | 86 in | 25 |
| 6R | 274 in | 22 ft 10 in | 86 in | 15 |
These are manufacturer-listed maximum capacities and exterior measurements for the models shown. Seating plans, accessibility equipment, and local requirements can change the usable passenger configuration. Micro Bird T-Series specifications.
