How do you have a layout such as this:

I have a similar list of items that require size information and this looks a nice neat way of formatting it...

It's a custom product layout, a case of creating a new layout, using the key parts inside of it along with html and css to put things where you want them. Have a look at adjusting layouts, start with the compact one as a good starting point.
