Assuming that the space between two adjacent elements is ''S'', then a certain element ''i'' must be positioned at:

Assuming that the space between two adjacent elements is ''S'', then the edge ''x<sub>i</sub>'' of certain element ''i'' must be positioned at:
  
 
<math>x_i = s_{i-1} + w_{i-1} + S</math>
 
<math>x_i = s_{i-1} + w_{i-1} + S</math>

* <math>S  = \displaystyle\frac{x_{max}-x_{min}-W}{N-1}</math>
 
* <math>S  = \displaystyle\frac{x_{max}-x_{min}-W}{N-1}</math>
  
Since the algorithm assumes elements that the elements are ordered by position of the left edges, this additional step must be performed before running the described algorithm.

This means that the position of the element is given by:

<math>X_i =x_i + w_i/2</math>

Since the algorithm assumes the elements being ordered by position of the left edges, this additional step must be performed before running the described algorithm.
  
 
The same algorithm can be used for distributing the elements vertically, in which case the equations are:
