Cans pull of ring


Use the calculator model to estimate what percentage of the target group in the Danish population will be able to pull the ring in the can with the stated dimensions. Try inserting different dimensions and forces. See the difference.


NB: Be sure only to use this calculation as a guideline when choosing dimension and opening force needed as the model is based on a limited set of data.


This is how you calculate how many people will be able to open

  1. Fill in the blanks with inner diameter for the ring on the can and the mechanical force needed to open the can (see mechanical test).
  2. Read the percentage of women and men who are able to pull the ring on the can depending on their age.
