Change single article width?

Hi,
can I change the maximum px for single article width somehow? When viewing in largest screen, it would be great if I could decrease the width to have shorter rows = easier to read.

I can change the width of right column, and by that decreasing the main area all together, but i would like to keep the width in category view...

With kind regards,
- Johan.

In template parameters you have option grid cell width

But there you can adjust the article layout in category view, right?

My concern is the single article view. With the largest screen and one right column its around 650 px. I would like it to be maximum around 500 px...

Article is resided automatically? how do you mean that? send link. Also if you downloaded template more that 7 days ago i recommend you download it again and overwrite just template files.
