If you’re mostly using a monitor I doubt you’d see a huge benefit from the jump in size.

As a personal anecdote I will say it’s easier to use a laptop around the house when it’s lighter and more compact.

Your best bet is to head over to a local Apple Store, Best Buy or anywhere else with display models and see how they feel to you.

I have both and prefer the 15

i started with a 13, then upgraded to 15. i miss the 13 and that’s what i’ll go back to eventually. doesn’t sound like much but it’s just a little bit harder to haul around places. or around the house if you work from home.

I would say if you have an external monitor just go with the 13. best of both worlds - ultimate portability, and you can always plug in if you need more screen space.

I’ve always preferred a smaller screen. 13” isn’t really that much smaller unless you’re blind.

I liked my 13” pro for school and have had it for ten years, easy to fit on desks and still have space for a notebook, also if you every plan to use it on flights the 15 is big enough to be pretty awkward.

I don’t use my 13 with monitors very much, so I’m looking at sizing up to a 16” this year. If you plan on primarily having it connected to monitors then a bigger screen on the laptop itself probably won’t matter to you.

Smaller is better in the bag and bigger one is better on the desk. Sounds like you might not appreciate the benefits of small size.
