[Qgis-user] get length of "custom" geometry in expression

[Richard McDonnell]

The easiest way to do this is to create a new column for the length 
variable
Just open the field calculator, leave the *create new field* box ticked, 
name your field in the *output field name* box
set your field width and precision and in the expression box just type 
/*$length*/

Richard McDonnell
