Galaxy S25 size comparison: Galaxy S25 Slim is thinner than Flip 6

Samsung will release four Galaxy S25 variants in the first half of 2025. The company will launch the base, Plus, and Ultra S25 models at Unpacked next week, but the Galaxy S25 Slim may or many not come to the market a few months later.

One thing that will set the Galaxy S25 Slim apart from the rest of the series is a thinner profile, and a fan-made render (via @OnLeaks) is now showing that size difference clear as day.

According to another render, this one shared by @UniverseIce, the profiles of the upcoming S25 phones have the following dimensions:

7.2mm — base Galaxy S25.
7.3mm — Galaxy S25 Plus.
6.4mm — Galaxy S25 Slim.
8.2mm — Galaxy S25 Ultra.

As expected, Galaxy S25 Ultra will be the thickest model. As for the Galaxy S25 Slim, it will beat its 2025 counterparts but won't be the thinnest Samsung smartphone ever. The old Galaxy A8 from 2015 will keep the crown, thanks to its 5.7mm profile.

The Galaxy S25 Slim won't outmatch the Galaxy Z Fold 6 either, the latter of which has a 5.6mm profile when unfolded but is quite chunky at 12.1mm when folded.

However, the 6.4mm Galaxy S25 Slim will outdo the Galaxy Z Flip 6 by a small margin. The Flip 6 measures 6.9mm when unfolded.

In any case, Samsung's upcoming Slim model won't break the 2015 record but will be the thinnest modern slab-type phone and hold its own against foldables.

First Samsung device: SGH-A800

Mihai is a blogger and column writer at SamMobile. His first Samsung phone was an A800 which took a lot of beating, and a part of him still misses the novelty of the clamshell design. In his free time, he enjoys watching shows, documentaries, and stand-up comedy; listening to music, taking walks, and occasionally playing old(er) video games.
