Galaxy S25 Edge, how does it compare against other flagships?

Now that I’ve seen and held the Galaxy S25 Edge in person, I understand the engineering behind Samsung’s new phone’s ultra-thin design. At 5.8mm thin, it’s impossible to deny that the S25 Edge’s slender design is an important part of its story – but how thin is it really?

Historically, phones have become slimmer with each iteration. However, we’ve reached a stage where we’ve grown accustomed to what is genuinely thin. That’s why I’d want to show you how the phone structure compares to some of the best phones on the market.

Remember how the first Motorola Razr from the mid-2000s compared to other flip phones of the time? Perhaps the iPod Nano’s bite-sized design made a significant difference over the standard iPod?

That’s the impression the S25 Edge needs to make if it’s going to sell its tiny design. I just do not want this to be an evolutionary step forward; rather, I want it to be revolutionary.

Galaxy S25 Edge vs. Galaxy S25 Ultra

Starting with the Galaxy S25 Ultra, the first image above shows how the Galaxy S25 Edge compares to Sammy’s high-end flagship. The Edge is clearly slimmer (5.8mm) than the Galaxy S25 Ultra, which is significantly thicker (8.2mm). This makes the Edge 31% slimmer.

What’s also essential to note is the weight difference, which I think is much more noticeable when I hold them both in my hands. Actually, the Galaxy S25 Edge remains difficult to use one-handed, but I can’t help but notice how much lighter it is. In fact, the Galaxy S25 Edge is 28% lighter. I honestly believe that is a far more essential parameter in a Galaxy S25 Edge vs. Galaxy S25 Ultra comparison.

Galaxy S25 Edge vs. iPhone 16 Pro Max

Another comparison that highlights the cumbersome size of today’s flagships is the S25 Edge versus the iPhone 16 Pro Max. I’ve always considered the iPhone Pro series to be thin and light by today’s standards. But it’s not even close, since the iPhone 16 Pro Max weighs an even heavier 8 ounces, making the it 32% lighter.

There is a significant difference in thickness, with the iPhone 16 Pro Max measuring 8.25mm. This means the phone is 34% slimmer than the iPhone 16 Pro Max.

Galaxy S25 Edge vs. Galaxy Z Fold 6

This next comparison is significant because it reveals a number of crucial facts. First and foremost, I’ve been using the Galaxy Z Fold 6 as one of my daily drivers for over 6 months, and it’s actually slimmer than the Edge at 5.6mm. The first shot shows how well they match up when placed side by side.

However, when the Galaxy Z Fold 6 is unfolded, it only covers half of its surface. When closed, the foldable phone expands to 12.1mm in thickness.

Second, the smartphone weighs 31% less than the Galaxy S25. This is yet another revealing area in which I can see a noticeable difference.

Galaxy S25 Edge vs. Galaxy Alpha

For this final one, I’d like to demonstrate how thin you can become. Despite being a decade old, the Galaxy Alpha demonstrates how tiny and compact phones were before everything became obnoxiously huge.

First and foremost, the size disparity between these two phones is ridiculous, as the Alpha is so small in comparison to the Galaxy S25 Edge.

Surprisingly, the Galaxy Alpha is slightly thicker at 6.7mm — but my side-by-side comparison shows otherwise, as they appear to be fairly identical. Another significant difference between them is their weight, with the Galaxy Alpha weighing less at 4.06 ounces.

This is precisely why I believe Samsung made a mistake by slimming down an existing flagship (say, the Galaxy S25 Ultra). Instead, I believe it would have been more ambitious to create a much thinner and smaller phone, such as the Galaxy Alpha, to take an unusual approach. Would you agree?
