Interrogating lists of unequal lenghths

I'm trying to understand how to assess the dimensions of a list containing elements of unequal length. Let's say I have the list with elements of equal sizes In[12]:= y={{1,2},{3,4},{5,6}} Out[12]= {{1,2},{3,4},{5,6}} In[13]:= Dimensions[y] Out[13]= {3,2} Using the Dimensions function I can determine the size of the resulting array. If, on the other hand, I set up the following list In[5]:= x={{1},{2,3},{4,5,6,7}} In[6]:= Dimensions[x] Out[6]= {3} The Dimensions command tells me I have only 3 elements. But, I need some way to figure out that the first sublist has length 1, second has length 2, and the third has length 4 in some automated fashion. I've looked through the other commands like Depth and Length but I don't see anything that does this. What's the right to do it? Thanks, Kevin
