Enter the total force needed (N) and the total pressure outside the cup (Pa) into the Suction Cup Size Calculator. The calculator will evaluate the Suction Cup Size. 

Suction Cup Size Formula

The following two example problems outline the steps and information needed to calculate the Suction Cup Size.

A = F / P

Variables:

  • A is the Suction Cup Size (m^2)
  • F is the total force needed (N) 
  • P is the total pressure outside the cup (Pa) 

How to Calculate Suction Cup Size?

The following steps outline how to calculate the Suction Cup Size.


  1. First, determine the total force needed (N). 
  2. Next, determine the total pressure outside the cup (Pa). 
  3. Next, gather the formula from above = A = F / P.
  4. Finally, calculate the Suction Cup Size.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total force needed (N) = 300

total pressure outside the cup (Pa) = 100,000

A = F / P = ?
