If you’re thinking about buying an iPhone 13, one of the first things you’ll probably wonder is: how big is it, really? It’s a fair question. We live in an age where smartphones come in all shapes and sizes—from ultra-compact to almost tablet-sized.
The iPhone 13 sits right in the sweet spot for many users. But Apple being Apple, it doesn’t just stop at one size. The iPhone 13 lineup comes in multiple models, each with a slightly different display size, dimensions, and weight.
So, if you’re trying to decide which iPhone 13 fits your hand, your pocket, or your lifestyle, this detailed guide will walk you through everything—dimensions, weight, screen size, and real-life usability—to help you make an informed decision.
Meet the iPhone 13 Family: Four Different Sizes
Before we dive into the numbers, it’s worth noting that the iPhone 13 isn’t just one phone. Apple released four variations under the iPhone 13 name:
- iPhone 13 Mini – The smallest of the group
- iPhone 13 – The standard flagship
- iPhone 13 Pro – Similar in size to the regular iPhone 13, but with pro features
- iPhone 13 Pro Max – The largest and most feature-packed model
Each of these has its own size and weight, but they all share a similar flat-edge design introduced with the iPhone 12 series, which gives them a clean, modern look with squared edges.
iPhone 13 Size Comparison Table
Let’s start with the cold, hard numbers. Here’s a side-by-side look at all four models in the iPhone 13 lineup:
| Model | Screen Size | Height (mm) | Width (mm) | Thickness (mm) | Weight (grams) |
|---|---|---|---|---|---|
| iPhone 13 Mini | 5.4 inches | 131.5 | 64.2 | 7.65 | 140 |
| iPhone 13 | 6.1 inches | 146.7 | 71.5 | 7.65 | 174 |
| iPhone 13 Pro | 6.1 inches | 146.7 | 71.5 | 7.65 | 204 |
| iPhone 13 Pro Max | 6.7 inches | 160.8 | 78.1 | 7.65 | 238 |
All models have the same thickness, but the Mini is obviously the smallest and lightest, while the Pro Max is the biggest.
iPhone 13 Mini: Small in Size, Big on Power
📏 Screen Size: 5.4 inches
⚖️ Weight: 140 grams
The iPhone 13 Mini is for those who want the power of a modern smartphone without the bulk. It’s the most compact flagship phone Apple has made in years. It easily fits in one hand, slips into any pocket, and is ideal for people who prefer a more traditional-sized phone without sacrificing speed, camera quality, or battery life (though its battery is smaller than its siblings).
The display still looks sharp and vibrant thanks to its high pixel density, and the phone supports Face ID, 5G, and MagSafe—all the bells and whistles.
📱 Who Is It For?
- People with smaller hands
- Those who want a lightweight phone
- Minimalists who don’t need massive screens
iPhone 13: The Just-Right Model
📏 Screen Size: 6.1 inches
⚖️ Weight: 174 grams
The standard iPhone 13 hits the “Goldilocks” zone for most users. Not too big, not too small—just right. With a 6.1-inch Super Retina XDR display, this phone is great for everyday tasks like browsing, texting, watching videos, or using apps. It fits comfortably in most hands and doesn’t feel too heavy or unwieldy.
Its weight and dimensions are nearly identical to the iPhone 13 Pro, but it’s slightly lighter due to the use of aluminum rather than stainless steel.
📱 Who Is It For?
- Average users who want balance
- Those who want a great screen without a bulky body
- People who don’t need “Pro” features but want excellent performance
iPhone 13 Pro: Premium Feel, Same Size as iPhone 13
📏 Screen Size: 6.1 inches
⚖️ Weight: 204 grams
Although the iPhone 13 Pro shares the same screen size and physical dimensions as the regular iPhone 13, it’s made with stainless steel (heavier and more premium) and includes a ProMotion display with a 120Hz refresh rate, improved cameras, and LiDAR scanning for AR applications.
If you’re someone who uses your phone for work, content creation, or gaming, the iPhone 13 Pro’s weight might be worth the trade-off for its premium features.
📱 Who Is It For?
- Content creators
- Power users
- Tech enthusiasts who want more control and camera performance
iPhone 13 Pro Max: The Largest iPhone Available
📏 Screen Size: 6.7 inches
⚖️ Weight: 238 grams
The iPhone 13 Pro Max is the largest, heaviest, and most feature-packed model in the lineup. It’s perfect for people who want the biggest display possible—whether for video, photography, productivity, or gaming.
It may not be ideal for one-handed use, but its larger battery and screen make it a powerhouse. It’s also the heaviest iPhone Apple has ever made, which some people love for the solid feel, while others find it a bit too hefty.
📱 Who Is It For?
- Heavy media consumers
- People who love big screens
- Professionals who use their phones as work tools
Screen-to-Body Ratio and Visual Experience
All iPhone 13 models feature edge-to-edge OLED screens with very thin bezels. The notch is still there, housing the front camera and Face ID sensors, but it’s slightly smaller than in previous models.
While screen size is often the most talked-about spec, screen-to-body ratio and pixel resolution also matter when talking about how “big” a phone feels in your hand or looks in use.
All iPhone 13 displays offer:
- High contrast ratios
- HDR support
- True Tone for color accuracy
- Haptic Touch
- Brightness up to 800 nits (typical), with 1200 nits for HDR
So regardless of which size you pick, you’re getting a premium display.

Size vs. Battery Life: Bigger = Longer Lasting?
One benefit of a larger phone is room for a bigger battery. Here’s how battery life compares across the lineup:
| Model | Battery Life (Video Playback) |
|---|---|
| iPhone 13 Mini | Up to 17 hours |
| iPhone 13 | Up to 19 hours |
| iPhone 13 Pro | Up to 22 hours |
| iPhone 13 Pro Max | Up to 28 hours |
So yes—generally speaking, the bigger the phone, the longer the battery lasts. But even the Mini does well for its size.
