A little bit smaller. I came from 2012/2015/2016 15" MBPs and went down to the 14". I felt very cramped and confined using the 13.3" screens, but my 14" luckily does feel more expansive than those did. Not quite as large as the old 15.4" size, though, and obviously significantly smaller than the new 16.2". The increased PPI and scaling settings allow you to get basically the same effective area as the 15.4" with slightly smaller elements. That's a nice feature.
I say this all the time, but I really do wish they'd make a Goldilocks 15.2" MBP with the current design. I'd be all over that. Overall, I'm very happy with my 14" MBP and its screen size / weight / size combination, and am usually happy I chose it over the 16".
Edit: Here's what I'm talking about with the scaling. 14" MBP scaled resolution are:
- Looks like 1800 x 1169
- Default: Looks like 1512 x 982
- Looks like 1352 x 878
- Looks like 1147 x 745
- Looks like 1024 x 665
The 15.4" MBP scaled resolutions were:
- Looks like 1920 x 1200
- Looks like 1680 x 1050
- Default: Looks like 1440 x 900
- Looks like 1280 x 800
- Looks like 1024 x 640
And the 13" MBP scaled resolutions were:
- Looks like 1680 x 1050
- Looks like 1440 x 900
- Default: Looks like 1280 x 800
- Looks like 1024 x 640 pixels
So you actually get
larger effective screen real estate at native / crisp / clear / perfect 2x scaling with the new 14" MBP than you did with the old 15.4" MBP due to the increased PPI - very close to what I consider the perfect effective resolution of 1680 x 1050. The actual elements are, of course, physically smaller, but it's still really nice to be able to put that much content on the screen with 2x scaling.
Edit 2: I realized this was all from a screen size perspective rather than a physical size / weight perspective. The 14” MBP feels very close in size and weight to the old 13” MBP - and closer in footprint to the 13” than the 15”. I think the dimensions would probably support that.
