When Apple launched the iPhone 12, it was more than just another smartphone release—it was the beginning of a sleek new design language, enhanced performance, and a shift toward 5G connectivity. But one of the most frequently asked questions, especially among buyers deciding between iPhone models, is: How big is the iPhone 12?
If you’re holding off on a purchase, comparing sizes, or just curious about what this popular model offers in terms of physical dimensions, screen size, and weight, you’ve come to the right place. This comprehensive guide will walk you through everything you need to know about the size of the iPhone 12, how it compares to other models, and what it feels like in everyday use.
iPhone 12 Overview at a Glance
Before diving into specific measurements, let’s take a quick look at what the iPhone 12 brought to the table:
- Release Year: 2020
- Display: Super Retina XDR OLED
- Design: Flat-edge aluminum frame, ceramic shield front
- Network: 5G support
- Model Variants: iPhone 12 Mini, iPhone 12, iPhone 12 Pro, iPhone 12 Pro Max
The standard iPhone 12 (the focus of this article) sat right in the middle of the pack—not too big, not too small—making it a popular choice for users looking for a balanced smartphone experience.
iPhone 12 Physical Dimensions
So, let’s get to the main question: How big is the iPhone 12?
Exact Measurements:
- Height: 146.7 mm (5.78 inches)
- Width: 71.5 mm (2.82 inches)
- Thickness: 7.4 mm (0.29 inches)
- Weight: 164 grams (5.78 ounces)
- Display Size (diagonal): 6.1 inches
Design Notes:
- The flat-edge aluminum frame gives the iPhone 12 a more squared look, reminiscent of older iPhone 4 and 5 models.
- It’s thin and lightweight, with a more compact footprint compared to the iPhone 11, despite having the same screen size.
The result? A phone that feels sturdy yet light in hand, large enough for immersive media consumption but still comfortable for one-handed use.
iPhone 12 Display Size and Screen-to-Body Ratio
While many phones measure display size diagonally, that number doesn’t always tell the full story. Here’s how the iPhone 12 stacks up visually.
Display Specs:
- Type: Super Retina XDR OLED
- Size: 6.1 inches (measured diagonally)
- Resolution: 2532 x 1170 pixels
- Pixel Density: 460 ppi
- Screen-to-Body Ratio: Approximately 86%
The OLED panel extends almost edge to edge, with minimal bezels and the familiar notch at the top. This makes the iPhone 12 feel bigger than older iPhones of similar height because so much of its front surface is actual screen space.
Comparing iPhone 12 to Other iPhone Models
To really understand how big the iPhone 12 is, it helps to compare it side-by-side with other models.

- iPhone 12 Mini: 5.4-inch screen, 131.5 mm tall, 135g
- iPhone 12: 6.1-inch screen, 146.7 mm tall, 164g
- Conclusion: The Mini is noticeably smaller and more compact but may feel cramped for media or typing.
Compared to iPhone 12 Pro:

Compared to iPhone 12 Pro Max:
- iPhone 12 Pro Max: 6.7-inch screen, 160.8 mm tall, 228g
- Conclusion: The Pro Max is significantly larger and heavier, best for users who prioritize a big screen for video, gaming, or productivity.
Compared to iPhone 11:
- iPhone 11: Also has a 6.1-inch screen, but is 8.3 mm thick and weighs 194g
- Conclusion: The iPhone 12 is slimmer and lighter, with a better screen (OLED vs. LCD).
How the Size Feels in Real Life
Numbers are great, but what does the iPhone 12 actually feel like in hand?
One-Handed Use:
- The 6.1-inch screen might seem large on paper, but thanks to its thin bezels and lightweight design, it’s still manageable with one hand for most users.
- Typing, scrolling, and app navigation feel natural, though reaching the top corners may require a second hand for smaller hands.
Pocket-Friendliness:
- It slips easily into most pockets thanks to its slim 7.4 mm profile.
- It balances well between compactness and display real estate.
Watching Content:
- With OLED and HDR support, watching videos or streaming shows on the iPhone 12 is a treat.
- The 6.1-inch display offers more than enough space for immersive media, without going overboard.
