A tallboy is relatively narrow, with more height to compensate for the storage space lost. The size of tallboys vary based on the model, but they’re characteristically taller than they are wide. In Australia, it’s common to see tallboys that are around 120cm in height, but this figure fluctuates with different styles. Its width is usually around 85cm, but that too can vary. If placed next to a queen bed, a tallboy will be less than half as long.
