Woocommerce list display

Hi, I’m an absolute novice with woocommerce, but I’d hoped a row of woocommerce products would display a bit better than this on the homepage

I had hoped to have a much larger image, with the title etc below, with each product repeated across what’s set to 5 columns. Can anyway see if I’m missing something obvious? I can’t see where it’s forcing the images to be so small and stacked one above the other.

Thanks a lot in advance!
