It’s not efficiency, it’s just not easy to visualise for people that have grown up elsewhere.
Julienne:
3mm × 3mm, 40-50mm in length
Brunoise:
Diced Julienne, 3mm cubes, can be as small as 1 or 2mm
Diced has no official size, but it’s bigger, can be 5mm to 20mm depending on the dish.
There are predictably French names for all the different sizes, this page gets a bit muddled with inches in there again, but since they’re all French, I’d say trust the millimetres.
