How to Measure Laptop Screen Size: 5 Easy Methods

Whether you're shopping for a new laptop bag, screen protector, or simply curious about your display specifications, knowing your laptop's screen size is essential. In this comprehensive guide, we'll walk you through five reliable methods to measure your laptop screen size.

Understanding Screen Size Measurement

Before diving into the methods, it's important to understand what "screen size" actually means. Laptop screens are measured diagonally, from one corner of the display to the opposite corner. This measurement is always in inches and does not include the bezel (the frame around the screen).

Method 1: Use Our Free Online Tool (Recommended)

The easiest and most convenient method is using our free screen size calculator. Here's how:

  1. Grab any standard credit card, ID card, or membership card
  2. Hold it against your screen
  3. Adjust the slider until the on-screen card matches your physical card
  4. Read your screen size instantly

This method requires no tools and takes less than 30 seconds.

Method 2: Measure with a Ruler or Tape Measure

If you prefer a hands-on approach:

  1. Turn off your laptop (optional, but makes it easier to see the corners)
  2. Place your ruler or tape measure at one corner of the screen
  3. Extend it diagonally to the opposite corner
  4. Important: Only measure the display area, not the bezel
  5. Read the measurement in inches (or convert from centimeters: 1 inch = 2.54 cm)

Pro Tip

If you only have a metric ruler, measure in centimeters and divide by 2.54 to get inches.

Method 3: Check Your Laptop Model Specifications

Every laptop has specifications that include screen size:

  1. Find your laptop's model number (usually on a sticker on the bottom)
  2. Search for "[Your Model Number] specifications" online
  3. Look for "Display" or "Screen" in the specs

This method is 100% accurate as it comes directly from the manufacturer.

Method 4: Check System Information (Limited)

While your operating system doesn't directly show physical screen size, you can find resolution and use it as a reference:

On Windows:

  • Right-click desktop → Display settings
  • Note your resolution (e.g., 1920 x 1080)

On macOS:

  • Apple menu → About This Mac → Displays

Common resolution-to-size mappings:

  • 1366 x 768: Often 11.6" or 14"
  • 1920 x 1080: Often 13.3", 15.6", or 17.3"
  • 2560 x 1600: Often 13" or 16"

Method 5: Use the Packaging or Documentation

If you still have the original box or documentation that came with your laptop, the screen size will be clearly listed there.

  • Buying accessories: Screen protectors, privacy filters, and cases all require exact measurements
  • Laptop bags: Ensure your new bag fits your device perfectly
  • Comparison shopping: Make informed decisions when upgrading
  • Resale: Accurately describe your laptop when selling
