Ever found yourself in a situation where you needed to measure the length of something but didn't have a measuring tape on hand? We've all been there!

Whether it's measuring a small space, checking the size of an object, or just satisfying our curiosity, having a reference point for length can be incredibly helpful.

In this article, we'll explore common things that are 10 centimeters long, providing you with a practical way to estimate length without a measuring tape. 

How big is 10 centimeters technically?

10 centimeters is 100 mm. I don't think that's much helpful though! If you have a better idea about inches then 10 cm is a little shy of 4 inches.

Placing four US quarters side by side creates a combined length of around 10 centimeters. These familiar coins are easily accessible, making them an ideal reference point for quick measurements.

Each quarter has a diameter of 24.26 milimeters, and when four quarters are placed together, they provide a reliable estimate of 10 cm.

So, the next time you need a quick measurement, reach for four quarters and visualize their collective length to gauge 10 centimeters accurately.

Found in most households, twist ties are versatile tools used for securing bags particularly trash bags or bundling wires. They typically come in different sizes between 4-32 inches long (10-80 centimeters). But there are smaller sizes too.

They are made of flexible metal wire coated in plastic or paper. Straighten out a twist tie and you have an instant 10-centimeter reference.

Four-inch or 10-centimeter Twist ties are commonly found in households, making them a convenient tool for quick measurements on the fly. Just make sure it is a 4" tie since there are plenty other sizes available in the market.

The standard size of a credit card is usually roughly 5.3 centimeters (2.125 inches) in height. Simply visualize the height of two credit cards side by side to estimate ten cm.

Credit cards are commonly carried in wallets, making them easily accessible when you need a quick measure.

Alternatively, if you have a business card nearby, this will also help. In general standard business cards are 3.5″x 2″, which means their height is 2 inches. So adding up two cards will give an estimate of ten centimeters. 

4. Paper clips

Paper clips, those versatile office supplies, can serve as a reference for estimating 10 centimeters. With a variety of sizes, smallest paper clips mostly come in 2.5 centimeters size.

By chaining up four such paper clips, you create an approximate length of 10 centimeters. Paper clips are common things in homes and offices, making them easily accessible. 

If you are only familiar with the most common paper clips, no need to worry. These come in a standard height of 4.4 cm. So lining up 2 and a half common paper clips will also give you a close estimate of 10cm.

5. A Standard Wooden Pencil

For example you can think of 5 instances of 2cm objects to estimate 10cm length. The next time you find yourself in need of a quick estimate, look around you and think creatively.
