These conversions show that 4 cm is a relatively small measurement, even when compared to feet or inches. But how do you measure it without a ruler? Okay, let’s begin with easy. First, we’ll discuss how you can measure it with the help of a ruler and then without a ruler.Â
How Big is 4 cm on a Ruler?
A typical ruler is about 12 inches long, which is approximately 30 cm. To measure 4 cm on a ruler, you need to find the 1.57-inch mark. This is slightly more than 1 and a half inches. It’s an easy measurement to make when you have a ruler in hand. But what if you don’t?
That’s where everyday objects come in handy. Let’s explore 13 things you can use to estimate How Big is 4 cm:Â
- Two US NickelsÂ

1. Two US Nickels
Two US Nickels
Coins are one of the easiest things to use when estimating measurements. In the US, a nickel is a common coin, and each one has a diameter of 2.12 cm. So, if you place two nickels side by side, their combined diameter would be 4.24 cm—just a tiny bit more than 4 cm.
You may not always have a ruler, but if you’ve got two nickels in your pocket, you can easily visualise How Big is 4 cm. And if you’re outside the US, try using your own country’s coins as a reference!
2. Standard Paperclip

Standard paper clips are a great reference for measurements. They can help you measure a wide range of measurements, including even small measurements such as 4 inches. A typical paperclip measures about 4 cm in length, making it a handy size comparison for 4 centimeters.Â

I highly suggest you to do this practically, and it will become a part of your memory that a typical paperclip is a good reference to estimate how big is 4 centimeters.Â
