Need to make image gallery wider

I'm giving my website a refresh and I'm adding text to this page with a sample of my photography on it. I'm using the gallery option I used in 2017, which I really like, as everything looks nice and even. I'd like everything to be at the same width and I'd like the text to have a little less space between lines. The text goes past the margins of the gallery; however, when I convert everything to a block, the width issue is fixed, but the photos are either cropped or spaced strangely. Is there a workaround to fix this? Do I need to install a plugin? Thanks.
