Screen Size Comparison: The Complete Reference Guide for Every Device
A screen size comparison is one of the most important things you can do before buying any device — whether it's a phone, tablet, laptop, monitor, or TV. But comparing screen sizes is harder than it looks. A 6.7-inch phone and a 6.9-inch phone sound nearly identical, yet the larger screen has about 6% more display area. A 55-inch TV and a 65-inch TV? The 65-inch gives you 40% more screen real estate. In this complete screen size comparison reference, we'll walk you through every dimension, calculation, and real-world consideration you need to make informed decisions about any display.
Before diving in, bookmark the Easy Compare screen comparison tool — it lets you compare any two screen sizes visually at true scale, so you can see exactly how they stack up against each other.
How Screen Size Comparison Works: The Basics
Screen sizes are measured diagonally from one corner to the opposite corner. This measurement dates back to the CRT era and has stuck around despite being somewhat misleading. Two screens with the same diagonal measurement can have very different areas depending on their aspect ratio. For example, a 24-inch 16:9 monitor has about 245 square inches of display area, while a 24-inch 16:10 monitor has about 259 square inches — that's 5.7% more screen despite the same "24-inch" label.
Here are the key measurements that matter in any screen size comparison:
| Measurement | What It Tells You | Why It Matters |
|---|---|---|
| Diagonal size | Overall screen size category | Quick comparison baseline |
| Width × Height | Actual physical dimensions | Desk space, pocket fit, wall mounting |
| Screen area | Total display space in sq inches/cm | True size difference between screens |
| Aspect ratio | Shape of the display | Content fit, letterboxing, productivity |
| Resolution | Pixel count (e.g., 1920×1080) | Sharpness and detail |
| PPI (pixels per inch) | Pixel density | Text clarity, image sharpness |
Phone Screen Size Comparison
Smartphone screens range from about 5.9 inches on the smallest phones to 7.6 inches on foldables like the Samsung Galaxy Z Fold. The most popular sizes in 2026 cluster around 6.1 inches (compact phones), 6.7 inches (standard large phones), and 6.9 inches (the largest non-folding phones). Here's how common phone screen sizes compare:
| Screen Size | Dimensions (20:9) | Area (sq in) | Example Phones |
|---|---|---|---|
| 6.1" | 2.64" × 5.53" | 14.6 | iPhone 16, Galaxy S25 |
| 6.3" | 2.73" × 5.71" | 15.6 | iPhone 16 Pro, Pixel 9 Pro |
| 6.7" | 2.90" × 6.07" | 17.6 | iPhone 16 Plus, Galaxy S25+ |
| 6.9" | 2.99" × 6.25" | 18.7 | Galaxy S25 Ultra, iPhone 16 Pro Max |
| 7.6" | 3.35" × 6.83" | 22.9 | Galaxy Z Fold 6 (inner) |
Notice that the jump from 6.1 to 6.9 inches adds about 28% more screen area — a much bigger difference than the 0.8-inch diagonal suggests. This is why a screen size comparison that looks at area, not just diagonal, is so important. Use the Easy Compare phone comparison tool to see these sizes at true scale.
TV Screen Size Comparison
TV screen sizes are where the diagonal-versus-area gap really matters. A 65-inch TV doesn't give you 18% more screen than a 55-inch TV — it gives you about 40% more. Here's the complete breakdown for popular TV sizes:
| TV Size | Width | Height | Area (sq in) | vs 55" |
|---|---|---|---|---|
| 43" | 37.5" | 21.1" | 791 | -39% |
| 55" | 47.9" | 27.0" | 1,293 | baseline |
| 65" | 56.7" | 31.9" | 1,809 | +40% |
| 75" | 65.4" | 36.8" | 2,407 | +86% |
| 85" | 74.1" | 41.7" | 3,090 | +139% |
The numbers don't lie: moving from a 55-inch to a 75-inch TV nearly doubles your screen area. For the best screen size comparison experience, try the Easy Compare TV comparison tool to visualize these sizes in your actual room.
Monitor Screen Size Comparison
Monitors come in a wider range of aspect ratios than phones or TVs, which makes comparing them more nuanced. A 27-inch 16:9 monitor and a 34-inch 21:9 ultrawide monitor have nearly the same screen height, but the ultrawide is much wider. Here's how popular monitor sizes stack up:
| Monitor | Aspect Ratio | Width × Height | Area (sq in) | Best For |
|---|---|---|---|---|
| 24" FHD | 16:9 | 20.9" × 11.8" | 247 | Office work, budget gaming |
| 27" QHD | 16:9 | 23.5" × 13.2" | 310 | Sweet spot for most users |
| 32" 4K | 16:9 | 27.8" × 15.7" | 436 | Creative work, immersive gaming |
| 34" Ultrawide | 21:9 | 31.7" × 13.2" | 418 | Productivity, video editing |
| 49" Super Ultrawide | 32:9 | 45.4" × 13.2" | 599 | Dual monitor replacement |
Interestingly, a 34-inch ultrawide has slightly less total area than a 32-inch 16:9 monitor, but many people prefer the ultrawide because the extra horizontal space feels more natural for multitasking. Read more in our ultrawide vs dual monitor comparison.
Tablet and Laptop Screen Size Comparison
Tablets bridge the gap between phones and laptops, with popular sizes ranging from 8.3 inches (iPad mini) to 13 inches (iPad Pro). Laptops range from 11.6 inches on ultraportables to 17.3 inches on desktop replacements. Here's a quick reference:
| Device | Screen Size | Area (sq in) | Weight |
|---|---|---|---|
| iPad mini | 8.3" | 26.9 | 293g |
| iPad Air | 11" | 46.6 | 462g |
| iPad Pro | 13" | 64.7 | 579g |
| 13" Laptop | 13.3" | 67.6 | ~1.2kg |
| 15" Laptop | 15.6" | 92.8 | ~1.7kg |
| 16" Laptop | 16.2" | 100.0 | ~2.0kg |
Screen Size Comparison by the Numbers: Area vs Diagonal
The most common mistake in any screen size comparison is relying solely on the diagonal. Here's a rule of thumb: when comparing two screens of the same aspect ratio, the area difference is roughly double the diagonal difference. Going from a 55-inch to a 65-inch TV is an 18% increase in diagonal but a 40% increase in area. This principle holds across all device categories.
For screens with different aspect ratios, you must calculate actual area. A 24-inch 16:10 monitor (259 sq in) has 5.7% more area than a 24-inch 16:9 monitor (245 sq in). That's a meaningful difference for productivity users who read documents side by side.
The Easy Compare screen comparison tool handles all these calculations automatically — just enter any two screen sizes and instantly see area, dimensions, and a true-scale visual comparison.
How to Do a Screen Size Comparison Yourself
If you want to calculate screen dimensions manually, here's the formula for a 16:9 screen (the most common aspect ratio for monitors and TVs):
Width = Diagonal × 0.872
Height = Diagonal × 0.490
For phones with a 20:9 aspect ratio:
Width = Diagonal × 0.434
Height = Diagonal × 0.906
Multiply width × height to get screen area. Or skip the math and use Easy Compare to do it instantly with a visual overlay.
Frequently Asked Questions
How do I compare screen sizes accurately?
Use a screen size comparison tool like Easy Compare that shows both screens at true scale. Look at screen area (not just diagonal), check physical dimensions for your space, and compare PPI to ensure sharpness meets your needs. You can also calculate manually using the formulas above.
Why does screen area matter more than diagonal size?
Diagonal size is a single dimension, but screens are two-dimensional. Two screens with the same diagonal but different aspect ratios have different areas. Screen area tells you the actual usable display space — the number that impacts your reading, watching, and working experience.
What is the best screen size for a living room TV?
For most living rooms with an 8-10 foot viewing distance, a 65-inch TV is the sweet spot. If you sit closer (6-8 feet), consider 55 inches. If you have a larger room or sit 10+ feet away, 75 inches or larger will give a more cinematic experience. Check out our TV size guide for detailed recommendations.
Is a bigger screen always better?
Not always. For phones, a screen that's too large becomes uncomfortable to hold and won't fit in your pocket. For monitors, a screen that's too large for your desk causes neck strain from head turning. The best screen size is the one that fits your space, viewing distance, and usage — not necessarily the biggest one available.
