Why Inches and Centimeters Matter Today

That’s why knowing what 42 inches in cm equals is more than just a random math fact—it helps you make better decisions when buying products.
For example, imagine you’re planning to buy a TV for a narrow wall in your room. The product listing says it’s 42 inches. But you live in a country that uses the metric system. You need to know the size in centimeters to see if it fits your space. This is where conversions become important.
How to Convert Inches to Centimeters
There’s a simple rule you can always count on. One inch equals 2.54 centimeters. So to convert any number of inches to centimeters, you multiply by 2.54. That’s it. Let’s see how that works with our main number.

Example:42 × 2.54 = 106.68 cm
So, 42 inches in cm equals 106.68 centimeters. Simple, right?
Inches vs. Centimeters: Which is Better?

Let’s do a few more quick conversions for better understanding:

Real-World Examples of 42 Inches in CM
Now that we know 42 inches is 106.68 centimeters, let’s talk about where this number appears in real life. One of the most common uses is for TV screens. TVs are measured diagonally. That means a 42-inch TV has a diagonal screen size of 106.68 cm. But what about the width and height of the screen? TVs today mostly come in a 16:9 aspect ratio. That means for every 16 units of width, there are 9 units of height. If you want to place a 42-inch TV in a cabinet or on a wall, you need to know both the width and the height.
Here’s a handy table to give you those details:
| Screen Size | Width (cm) | Height (cm) | Diagonal (cm) |

These measurements are rounded but very useful for estimating.
Why You Should Know the Size Before You Buy
Knowing the exact size in centimeters before making a purchase helps avoid costly mistakes. Imagine buying a motorized TV lift that only fits up to 100 cm. If you don’t know that your 42-inch TV is 106.68 cm across, it might not fit. That could mean returning the item or needing a new design. This also applies when mounting TVs between two windows, in a niche, or over a fireplace. In these situations, 42 inches in cm gives you a clearer picture of whether a TV will fit without overwhelming the space.
Online Shopping and Metric Measurements
With global online marketplaces like Amazon, eBay, and AliExpress, products are listed in various measurement systems. 42 inches in cm sofa may be listed in centimeters while the TV it’s meant to hold is in inches. This mix-and-match style of shopping makes conversions vital. Luckily, many websites now have automatic converters, but knowing the formula gives you more control. You don’t have to rely on external tools to get basic info.
Common Mistakes to Avoid
Many people assume that a 42-inch screen is 42 inches wide. But remember, screen size is measured diagonally, not across the width. That’s a huge difference when you’re planning space for a new setup. Others might use inaccurate online converters or round up too much. Always use 2.54 as the conversion factor and avoid guessing.
Professionals Rely on Precision
Interior designers, architects, and custom cabinet makers rely on precise measurements. They often convert screen sizes before designing layouts. In these cases, even a small mistake can cause big issues. That’s why it’s essential to know that 42 inches in cm means exactly 106.68 cm.
