Why Knowing Your Laptop Screen Size Matters?
Before we dive into the methods, let’s understand why you might need to know your laptop’s screen size. Whether you’re shopping for a protective case, looking for a replacement screen, or comparing your laptop to newer models, knowing the exact screen size is essential.
Laptop accessories like bags, screen protectors, and privacy filters are all sized based on your screen dimensions. Plus, if you ever need to replace your screen, having the correct size information ensures you get the right part the first time.
Method 1: Measure Your Laptop Screen Manually
The most direct way to how to measure laptop screen size is with a simple measuring tape or ruler.
Here’s how to do it correctly:
- Open your laptop so the screen is at a 90-degree angle
- Place your measuring tape at the bottom-left corner of the actual screen (not the bezel)
- Stretch the tape diagonally to the top-right corner of the screen
- Read the measurement in inches or centimeters
Important tip: Only measure the screen area where images appear, not the black border around it. Laptop screens are always measured diagonally, just like TVs. If you get a measurement in centimeters, divide by 2.54 to convert to inches (the standard for laptop screens).
Common mistake: Many people measure from the outer edges of the laptop lid, which gives you the wrong size. Always measure just the screen area itself.
Method 2: Check Your Laptop’s System Information
If you want to how to determine laptop screen size without measuring, your laptop’s system information can help. While Windows doesn’t directly show screen size in settings, you can find your model number and look up the specifications:
- Press Windows key + R to open the Run dialog
- Type “msinfo32” and press Enter
- Look for “System Model” in the information that appears
- Search online for your model number + “screen size”
This method works because most laptop manufacturers list detailed specifications online. For more help finding your model information, check out our guide on how to check model & specs of any Windows laptop.

Several websites can help you find my laptop screen size automatically. These online tools detect your screen resolution and can often calculate the physical size:
- Visit whatsmyscreen.com or similar screen detection sites
- Follow the on-screen instructions (usually involves comparing a reference object)
- The tool will display your screen size and resolution
These tools are especially helpful if you don’t have a measuring tape handy. They use your browser’s information to estimate screen size based on resolution and pixel density.
Method 4: Check Your Laptop’s Physical Dimensions
Sometimes you need to know more than just the screen size – you might need my laptop width and height for a case or bag. Here’s how to how to measure laptop size completely:
- Close your laptop completely
- Measure the width (left to right) at the widest point
- Measure the depth (front to back) at the deepest point
- Measure the thickness (when closed)
Remember: The overall laptop size is always larger than the screen size due to the bezel (the frame around the screen) and the laptop’s body. A 15.6-inch laptop might be 14 inches wide and 9.5 inches deep when closed.
Method 5: Look for Documentation or Labels
The easiest way to check my laptop screen size might be right on your laptop or in its documentation:
- Check the bottom of your laptop for a specifications sticker
- Look for labels that include screen size (often shown as 15.6″, 14″, etc.)
- Check your original packaging or user manual
- Look for model-specific information in the battery compartment
Many manufacturers print the screen size directly on the laptop, though it might be part of a longer model number or specification list.
