Samsung Galaxy vs iPhone Screen Size 2025: Full Comparison

This guide compares every current flagship model side by side, so you can make a decision based on real dimensions, not marketing copy.

Direct Head-to-Head: Comparable Models
Standard / Base Model: Galaxy S25 vs iPhone 16
The Galaxy S25 (6.2″) and iPhone 16 (6.1″) are almost identical in actual hand size — both fit comfortably in most hands and work one-handed with occasional stretching. The S25 is 0.7 mm narrower than the iPhone 16 (70.5 mm vs 71.5 mm), making it fractionally easier to grip. The iPhone 16 is 0.7 mm taller. For most people this is a wash — the real differences are software and ecosystem.
Plus / Large Model: Galaxy S25+ vs iPhone 16 Plus
Both are 6.7″ phones, but the S25+ is noticeably more pocketable: 158.8 × 75.8 mm vs 160.9 × 77.8 mm for the iPhone 16 Plus. The S25+ is 2.1 mm shorter and 2 mm narrower, which adds up when you're reaching across a 6.7″ screen with one hand. Both weigh in the 190–203 g range — heavy but manageable.
Ultra / Pro Max: Galaxy S25 Ultra vs iPhone 16 Pro Max
At 6.9″ both are essentially the same screen size, and their body dimensions are nearly identical (162.8 × 77.6 mm vs 163.0 × 77.6 mm). The Pro Max is heavier at 227 g vs 218 g. Both require two hands for comfortable use. The Ultra edges it in pixel density (505 PPI at QHD+ vs 460 PPI), while the Pro Max wins on video quality (ProRes, 4K 120fps Dolby Vision).
Screen Quality: Beyond Just Size
Raw screen dimensions only tell part of the story. Here's how the displays compare on quality metrics:
| Feature | Samsung Galaxy S25 Series | iPhone 16 Series |
|---|---|---|
| Panel Type | Dynamic AMOLED 2X | Super Retina XDR OLED |
| Refresh Rate | 1–120Hz adaptive | 60Hz (base/Plus) / 1–120Hz Pro |
| Peak Brightness | 2600 nits | 2000 nits |
| Aspect Ratio | 19.5:9 (taller) | 19.5:9 |
| Always-On Display | ✅ All models | ✅ Pro only |
Samsung wins on raw brightness (2600 vs 2000 nits) and always-on display across the entire lineup. iPhone Pro wins on video capture quality and color accuracy for photo editing. For everyday media consumption — streaming, social, gaming — the difference is minimal; both are world-class OLED panels.
One-Handed Usability by Screen Size
One-handed use is where screen size matters most in daily life. Here's a practical guide:
- Under 6.2″ (Galaxy S25 / iPhone 16): Comfortable one-handed reach for most adults with medium or larger hands. Thumb reaches all corners with minor shifting.
- 6.3–6.7″ (S25+ / iPhone 16 Plus / 16 Pro): Two-handed preferred for typing. Reachability mode or shifting grip required for one-handed use. Still pocketable in most pants.
- 6.9″ (S25 Ultra / iPhone 16 Pro Max): Two-handed phone. Jacket/cargo pocket territory. Best for media and productivity; not commute phones.

FAQ
Is Samsung Galaxy screen bigger than iPhone?
At the base level, yes slightly: Galaxy S25 is 6.2″ vs iPhone 16's 6.1″. At the Plus level they're both 6.7″, and at the Ultra/Pro Max level both are 6.9″. The bigger difference is the body size — Samsung tends to pack more screen into a slightly narrower, shorter phone.
Which has better screen quality, Samsung or iPhone?
Both use top-tier OLED panels. Samsung's Dynamic AMOLED 2X hits 2600 nits peak brightness (vs Apple's 2000 nits) and has always-on display on all models. iPhone Pro's display is slightly more color-accurate out of the box for photography and ProRes video. For everyday use, you won't notice a difference.
Can I use Galaxy S25 Ultra one-handed?
Technically yes, but comfortably no. At 162.8 × 77.6 mm and 218 g, the S25 Ultra is a two-handed phone. Samsung's One-Handed mode and reachability gestures help, but if one-handed use matters to you, go for the base S25 (6.2″, 70.5 mm wide).
