Members of the University’s Maths society, called SUMS, have put an end to bare branches, by calculating the amount of baubles, tinsel and lights needed, as well as the size of the essential star on top.
Department store Debenhams set the University the Christmas themed challenge to create the formulas for the perfectly decorated Christmas tree and it is also available below as a calculator.
If you've found your ideal Christmas tree but want to ensure you use the appropriate amount of decorations then the calculator will have the answer.
The formulas – which are being rolled out for use by Debenhams personal shoppers nationwide – are as follows:
For example, a 180cm (6ft) Christmas tree would need 37 baubles, around 919 cms of tinsel and 565 cms of lights and an 18cm star or angel is required to achieve the perfect look.
