Blog Title Font Size

Hi, I have changed the layout of my website and now use large headings. This has also meant the blog titles are now huge on a desktop and only fit a few words on each line.

Is there a way of customising the font size of just the blog titles please?

I use the Horizon Template.

Example of huge Blog titles:

Many thanks in advanced!
