Even padding on a gallery block 7.1

I'm looking for help making an even gallery grid.

Our client would like the spacing to be equal - as in the image on the right

Adjusting the padding increases the spaces between the images AND the image rows.

Help inputting the code would be great, thank you

Can you share link to page where you use gallery block? We can check easier

Thank you - yes
