Best linux distro for dual booting

Hello! So I have used linux mint for dual booting and its great! My main problem is that I have around 30 GB to spare for linux and I just run out of space pretty quickly. I wanted to ask, is there a distro that is more lightweight than linux mint that will work best with low amount of storage? I do prefer debian based distros but I am willing to try arch ones as well. Any recommendations will be very appreciated!
