The matrices in my form are really tall and skinny. I want them to be wider.

I believe you are referring to this form: http://www.jotform.com/52104026713947

I did a lot of changes to it, since there was a lot of CSS that made the form looks like it is now:

1) There was a max-width on matrix and even text box fields:

As you see the width it's limited to 3px, that's why the look skinny. What I did was to increase it or in some cases removed that limit.

2) Also, I reduced the table width of the matrix, it was a 700, I reduced it to 600:

3) The Cell Width of the Matrix that contains check boxes was to wider, it was at 350, I reduced it to 50:

Now the form looks like this:
