MacBook Air 13" Vs 15" for Adobe

I'm thinking of purchasing my first ever MacBook, I'm looking at the M5 24gb 1tb.

The main dilemma I have is, would the 13" be too small? I'm switching from a 10yr old dell xps 15" which I like the screen size but it's just perhaps a bit too big for carrying around. I'll be mainly using InDesign and illustrator and I like having the toolbars open.

I won't be carrying it around too often but when I do I'd like to easily pick up and go. The 15" should be lighter than what I have now. Anybody using theirs with Adobe and can share insight on if the 13" is just a bit too small, the 15" ok to carry around?
