The BestFitLineRuler was invented by Miles Hudson, whilst invigilating an exam and watching pupils struggle to draw their best fit lines using traditional rulers. Miles is a physics teacher who also writes textbooks for secondary schools.

Our company is a traditional cottage industry. The rulers are injection moulded in Meadowfield, County Durham, and then printed by hand in Durham City. Buy them and support UK workers!
