Laptop Size Guide

Understand, Measure, and Find the Right Fit

What Laptop Size Really Means

Laptop size refers to the diagonal measurement of the screen, not the overall dimensions of the body. It’s measured in inches from one corner of the screen to the opposite corner.

How to Measure It Using Inches or Centimeters

Use a measuring tape or ruler. Start from the bottom-left corner of the screen (not the bezel) and stretch it to the top-right corner. Convert inches to centimeters by multiplying by 2.54.

How to Find Laptop Size on Windows 10

On Windows 10, right-click on the desktop and select “Display settings.” Scroll down to view your screen resolution. While this doesn’t give you the physical size, it helps determine screen clarity (DPI). Use your model number to Google the exact size.

How to Measure Your Laptop for a Bag

• Measure the depth (front to back)
• Measure the height (top to bottom including screen)

Compare these measurements with the internal dimensions of the bag you’re planning to buy.

FAQs

Whether you’re shopping online or in-store, knowing your laptop size helps you make better choices.

What Does “Laptop Size” Mean?

When we talk about “laptop size,” we usually mean the screen size, not the full laptop body. This screen size is measured diagonally—from one corner of the screen to the opposite corner. That means if your screen measures 15.6 inches from bottom-left to top-right (just the display, not the bezel), your laptop is called a 15.6-inch laptop.

How to Measure Laptop Size in Inches or CM

What You’ll Need:

• A measuring tape or ruler
• A steady hand
• Your laptop (opened)

Step-by-Step Guide

Step-by-Step Guide:

1. Open Your Laptop

Lay the laptop on a flat surface and fully open the screen. This makes it easier to measure diagonally.

2. Place the Measuring Tape at One Corner

Start at the bottom-left corner of the screen (not the outer case, just the screen).

3. Stretch It Diagonally to the Opposite Corner

Measure across to the top-right corner of the screen. Avoid including the black border (bezel) around the screen.

4. Read the Measurement

• If you’re using inches, your measurement will match standard laptop listings like 13.3″, 14″, 15.6″, etc.
  
• To measure laptop size in cm, just use a metric tape or multiply inches by 2.54.
  

Example: 15.6 inches × 2.54 = 39.62 cm

You can now describe your screen size both ways!

How to Measure Laptop Size for a Bag

If you want a perfect-fit laptop bag, don’t stop at just screen size. Measure the full body of your laptop.

Dimension	How to Measure
Width	Side to side, across the keyboard
Depth	Front to back, along the side edge
Height	Thickness when closed (top to bottom)

Why Full Dimensions Matter

Laptop sleeves and backpacks are sized based on the whole laptop body—not just the screen.

So if you’re buying a laptop sleeve or case, don’t only rely on the “15.6-inch” label. Check the body dimensions too!
