Printing out LaTeX Variables

I am using a LaTeX class file which sets various parameters such as margins, line spacing, ... according to the parameters passed to it. For some reason, the end result does not look right. Some margins are not properly set. I'd like to print out the values of various variables that LaTeX have computed along the way to see where the problem is. For instance, I'd like to know what the value of

is in a certain line of code. Is there a way to ask LaTeX to print out such information?


For debugging page layout, Peter Wilson's layouts package is the way to go. Here's an example for visualising the page design and seeing the dimensions used for it:


There are many features to fine-tune the information returned by the package. It also provides the \prntlen command to print the size of a length in case you don't need so much information.
