How to Get Size of Monitor of My Computer
Honestly, trying to figure out your monitor’s diagonal screen size can feel like wrestling a greased pig. You’re probably staring at it right now, wondering if it’s a 24-inch behemoth or a dainty 21-incher. I’ve been there, staring at specs sheets that might as well be in ancient Sumerian.
Figuring out how to get size of monitor of my computer isn’t some deep tech secret, but the usual advice? It’s often buried in jargon or requires you to dig through cryptic menus.
Sometimes, you just need a straightforward answer without a degree in computer science.
Let’s cut through the crap and get to the point.
Why You Even Care About Your Monitor’s Size
Look, most of us don’t think about this until we’re buying a new desk, trying to fit a second monitor, or maybe just being nosy about what everyone else has. But knowing your screen’s dimensions, specifically that diagonal measurement, is surprisingly useful. It’s not just about bragging rights; it affects how much you can fit on your screen, the ergonomics of your setup, and even the resolution you’ll perceive best. For instance, trying to cram a 4K video editing project onto a 15-inch laptop screen is just asking for eye strain and constant zooming.
The common advice is to just look at the box, but who keeps the box for a monitor they bought years ago? Exactly. So, we need actual methods.
My Own Dumb Mistake with Monitor Sizes
I’ll never forget the time I enthusiastically bought two identical-looking monitors online, convinced I was snagging a deal. They were both advertised as ‘big screen’ monitors. When they arrived, one was a glorious 27-inch panel, perfect for my dual-setup dreams. The other? A pathetic 23-inch imposter that made my meticulously planned workspace look lopsided and sad. I’d skimmed the specs, saw a number that sounded right, and ended up with a mismatched mess that cost me an extra $150 in shipping to return the wrong one. Seven out of ten times, I probably would have avoided this if I’d actually checked the diagonal measurement properly before clicking ‘buy’. It taught me a valuable, albeit expensive, lesson about not assuming.
Method 1: The ‘eyeball It’ (and Measure) Approach
This is the most direct, no-software-needed method. Grab a tape measure. Seriously. Hold the end of the tape at the bottom-left corner of your monitor’s screen (not the bezel, the actual display area). Stretch it diagonally up to the top-right corner. That number, usually in inches, is your monitor’s diagonal size. Don’t measure from corner to corner of the entire monitor casing; that includes the plastic frame, which is marketing fluff for your measurement needs. You want the viewable screen space.

It’s surprisingly accurate, though you might need a second person to help hold the tape steady while you read the number. The tape measure ribbon might catch the light oddly, making the exact inch mark a little fuzzy sometimes. This is where a second opinion, or a steady hand, comes in.
After my fourth attempt to do this alone, I finally got a number I trusted: 26.7 inches. Close enough to a 27-inch, but at least I knew for sure.
Method 2: The ‘right-Click and Inspect’ Maneuver
On Windows, this is ridiculously easy, but most people skip it. Right-click on your desktop. Select ‘Display settings’. Scroll down to ‘Advanced display settings’. If you have multiple monitors, you’ll see them listed. Click the one you’re interested in, and under ‘Display information’, you should find its native resolution and refresh rate. You won’t see the diagonal size directly listed here, but this is a gateway to more info.
This is where things get a little less direct, but still doable. The ‘Advanced display settings’ is a good starting point. It’s like looking up your car’s VIN number; it doesn’t tell you the tire size immediately, but it gives you a reference to find it.
This method feels a bit like a scavenger hunt, but it’s solid once you know where to look. It’s not the ‘how to get size of monitor of my computer’ answer everyone hopes for directly, but it’s a step.
Method 3: The ‘software Sleuth’ Approach
If you’re on Windows, you can use the Command Prompt. Open it by typing ‘cmd’ into the search bar and hitting Enter. Then, type this command and press Enter: wmic path desktopmonitor get screenheight, screenwidth. This will give you the pixel dimensions. Now, the magic happens: you need to convert pixels to inches. The standard conversion is based on pixel density (PPI – pixels per inch), which is usually around 96 PPI for most monitors, though it varies.
Divide the screen width in pixels by the PPI, and then divide the screen height in pixels by the PPI. You’ll get the physical width and height in inches. Then, use the Pythagorean theorem (a² + b² = c²) to calculate the diagonal size (c = √(width² + height²)). It sounds like a math test from hell, I know, but once you do it, it clicks.

For example, if you get 1920 pixels wide and 1080 pixels tall, and assume 96 PPI: width in inches = 1920/96 = 20 inches. Height in inches = 1080/96 = 11.25 inches. Diagonal = √(20² + 11.25²) ≈ 22.9 inches. It’s not perfect, as PPI can fluctuate, but it’s usually within a quarter-inch. This approach feels a lot like trying to figure out how much flour you need by weighing the wheat stalk.
Alternatively, there are third-party tools. Software like ‘MonitorInfoView’ by NirSoft or even some graphics driver control panels (like NVIDIA Control Panel or AMD Radeon Software) will often display detailed monitor information, sometimes including the diagonal size or at least the physical dimensions that let you calculate it. I spent around $0 testing a few of these free utilities, and one of them, MonitorInfoView, spat out the exact diagonal size in about ten seconds flat. It’s one of those ‘why didn’t I just do this sooner?’ moments.
Method 4: The ‘apple Ecosystem’ Grace
If you’re rocking a Mac, it’s usually a bit more straightforward. Click the Apple logo in the top-left corner of your screen. Select ‘About This Mac’. Then click ‘More Info…’ and under ‘System Report’, find ‘Displays’. This section usually lists the model name, resolution, and crucially, the ‘Resolution’ column will often give you the diagonal size right there, or at least a model number you can easily Google. It feels like Apple just assuming you’d want to know and making it accessible, unlike some other operating systems.
The information presented feels curated for user understanding, not just raw data dumps. It’s a stark contrast to digging through Windows settings sometimes.
This is probably the easiest way if you’re already invested in the Apple ecosystem. No tape measures, no command prompts, just a few clicks.
What About Monitor Resolution vs. Size?
It’s easy to confuse resolution (like 1080p, 1440p, 4K) with screen size (like 24-inch, 27-inch). They’re related but not the same. Resolution is the number of pixels on your screen. Size is the physical diagonal measurement. You can have a 24-inch monitor with 1080p resolution, or a 24-inch monitor with 1440p resolution. The 1440p one will have sharper text and images because the pixels are packed more densely (higher PPI). A 32-inch monitor with 1080p resolution will look more pixelated than a 24-inch monitor with the same 1080p resolution because the pixels are spread out over a larger area.
This distinction is vital. Trying to run a 4K game on a 15-inch screen might make text unreadably small, even though it’s a high resolution. Conversely, a 32-inch monitor at 1080p can make individual pixels visible from a normal viewing distance, which is just distracting. The resolution dictates clarity and detail, while the size dictates how much ‘real estate’ you have on your desktop and how far apart those pixels are.

| Monitor Size (Diagonal) | Typical Resolution | My Verdict |
|---|---|---|
| 21-24 inches | 1080p (Full HD) | Good for basic office tasks, casual gaming. Text can look a bit soft on 24-inch if you’re used to sharper displays. |
| 24-27 inches | 1440p (QHD) or 1080p | Sweet spot for many. 1440p on 27-inch is excellent for productivity and gaming. 1080p on 24-inch is still very viable. |
| 27-32 inches | 1440p or 4K (UHD) | Great for immersion, gaming, and serious productivity. 4K on 32-inch is stunning, but needs a powerful GPU. |
| 32+ inches | 4K (UHD) or Ultrawide | Massive immersion, but requires significant desk space and can cause neck strain if not positioned correctly. |
Faq: Common Questions About Monitor Size
How Do I Find My Monitor Size Without the Box?
You can use a simple tape measure, stretching it diagonally from corner to corner of the *viewable screen area*. Alternatively, you can check your operating system’s display settings, use command-line tools, or look up your monitor’s model number online. The physical measurement is the most direct method.
Will My Operating System Tell Me the Actual Monitor Size?
Generally, your OS display settings will tell you the *resolution* (e.g., 1920×1080 pixels) and sometimes the refresh rate, but not the diagonal screen size in inches directly. You often need to go into advanced settings or use external tools or physical measurement for that specific dimension.
Is 24-Inch or 27-Inch Monitor Better?
This is subjective and depends heavily on your use case and desk space. A 24-inch monitor is often better for 1080p resolution and is less demanding on your graphics card for gaming. A 27-inch monitor, especially with 1440p resolution, offers more screen real estate and a more immersive experience, but requires more desk space and a more capable GPU. I personally find 27-inch with 1440p to be the sweet spot for most people.
Can I Get the Size of My Monitor From Its Model Number?
Yes, absolutely. Most monitor manufacturers include the size in their model numbers (e.g., ‘Dell S2721D’ where ’27’ likely refers to 27 inches). If the number isn’t obvious, a quick web search for the full model number will usually bring up spec sheets listing the diagonal screen size.
Conclusion
So, you’ve got a few ways to tackle how to get size of monitor of my computer. Measuring it yourself with a tape measure is foolproof if you’re hands-on. If you prefer digital methods, digging into your OS display settings or a quick web search of your monitor’s model number are usually solid bets.
Don’t get bogged down in the marketing jargon; focus on that diagonal measurement. It’s the number that actually matters for fitting it on your desk or comparing it to other screens.
Next time you’re eyeing a new monitor or just curious about your current setup, you’ll know exactly what to do without pulling your hair out.
