Limit Excerpts size in FrameMarket GridMarket theme


Im using latest version of FrameMarket GridMarket theme and Market Press plugin. I have excerpts activated on my site and it automatically adds excerpts to the main page and each category. See my test site ( The only problem is that these excerpts are pretty long.

I know there is a option to manually enter excerpts into each post to customize each excerpt which is a great feature. However, if you have 1000+ products to list it starts to get pretty burdensome fast.

No since there is an automatic display of excerpts already integrated into the FrameMarket GridMarket theme, Is there a way to limit the automatic excerpts in size? Say to 6 or 10 words maximum?

Thank you
