Change the distribution of spaces on individual product pages

Hi,

How can I change the spacing ratios of individual product pages, in general?

Now it seems that the space occupied by the product image is 50% and the space occupied by the features area is another 50%.
How can I reduce the image space to 30% or 40% and increase the feature space to 70% or 60%?

That for all products. For tablet, laptop and computer screens.

And I would also like to know if I can reduce the spaces that exist on the sides a little
Now there are two lateral spaces on large screens, how can I reduce it, so that there is more space in the two central areas?

(I attach an image so you can understand what I’m saying more)

Thank you!

Ana
