Measure The Screen Diagonally
To measure your laptop screen size, you need a ruler or a measuring tape. Choose a tool that shows inches clearly. Make sure the tool is straight and not bent.
Start by closing the laptop gently. Measure only the visible screen area, not the frame or bezel around it. Place the ruler at the bottom-left corner of the screen.
Stretch the ruler diagonally to the top-right corner. Note the number where the ruler ends. This number is the screen size in inches. Usually, laptop screens are between 11 and 17 inches.
| Step | Action |
|---|---|
| 1 | Get a ruler or measuring tape with inches |
| 2 | Close the laptop gently |
| 3 | Measure from bottom-left to top-right corner diagonally |
| 4 | Read the length in inches; this is the screen size |

Check Laptop Specifications
Check the laptop’s official website for detailed specifications. The model number helps find the exact screen size quickly. Manufacturer sites usually list screen size in inches under display features.
Look for labels on the laptop itself. Often, a sticker on the bottom or near the keyboard shows the screen size and model details. This method is simple and fast.
| Method | Details | Where to Check |
|---|---|---|
| Find Specs Online | Use model number to search screen size on the official site | Manufacturer’s website |
| Using Manufacturer Labels | Read stickers on laptop for screen size info | Bottom or near keyboard |
Use System Settings
To find your laptop screen size on Windows, right-click the desktop and choose Display settings. Scroll down to see the Display resolution. While it does not give size directly, the resolution helps estimate it.
For exact size, open Control Panel, go to Display, then Screen Resolution. Here, you can view details about your screen.
On a Mac, click the Apple menu and select About This Mac. Click Displays to see the screen size and resolution. This shows the exact size in inches.

Compare With Common Screen Sizes
Most laptops have screen sizes between 11 inches and 17 inches. Common sizes include 13.3″, 14″, 15.6″, and 17.3″. Smaller screens like 11″ or 12″ are lighter and easy to carry. Bigger screens, such as 15.6″ and 17.3″, give more space for work and fun. Choose a size that fits your daily use and comfort. If you move a lot, smaller screens are better. For watching movies or editing photos, bigger screens work well.
| Screen Size (inches) | Common Use | Pros | Cons |
|---|---|---|---|
| 11 – 12 | Travel, basic tasks | Light, easy to carry | Smaller display |
| 13.3 – 14 | Everyday use | Balanced size, portable | Limited screen space |
| 15.6 | Work, multimedia | Bigger screen, good for tasks | Heavier, less portable |
| 17.3 | Gaming, design | Large display, great visuals | Very heavy, less mobile |
Tips For Accurate Measurement
Measure the screen diagonally from one corner to the opposite corner. Use a ruler or tape measure for accuracy. Avoid measuring the entire laptop size; just the screen.
Do not include the screen frame or bezel in your measurement. The screen size is only the visible part. Hold the ruler straight and steady to avoid errors.
Without tools, use a piece of paper or string to mark the diagonal length. Then measure that length with a ruler. This method gives a close estimate but less exact.
Common mistakes include measuring width or height instead of diagonal. Also, do not include the laptop edges or keyboard area. Accuracy depends on careful placement of the measuring tool.
