1. 2.5X A Standard Brick

There are different brick sizes and shapes globally. So, the exact dimensions can vary depending on the location and specific construction requirements.

And if you’re familiar with them, imagine something two and a half times as long to get a perspective of 50 cm.

2. 3X A US Dollar Note

The US dollar notes are an excellent way to understand different short-term lengths, starting with six inches since they are 6.14 inches long, regardless of the denomination. 

And since 50 cm belongs in that category of short lengths, we can use them too to understand how long it is. 

To do so, you can compare it to three US dollar bills arranged end-to-end in a straight line on a flat surface. They stretch to about 48 centimeters, close enough.

3. 6X A Debit Card

Debit cards are the most commonly used mode of payment in many countries, including the United States. So, they are reliable references for short lengths due to their familiarity and ease of accessibility. 

These cards are usually 3.375 inches (8.6 cm) long. 

So, imagine how long six would be if arranged end-to-end in a straight line. That exceeds the 50-cm mark by only one centimeter.

4. 6X A Standard Playing Card

Do you play card games such as poker, bridge, blackjack, or solitaire? 

If you do, standard playing cards could be just what you need to understand how long 50 cm is. 

Standard playing cards are slightly longer than debit cards, at 3.5 inches (8.9cm). 

And since they’re usually found in plenty (a deck holds as many as 52, including the two jokers), pluck only six and arrange them on a flat surface lengthwise. They go beyond 50 cm by only three centimeters.

5. 6X A Business Card

Business cards are primarily used for networking and making professional connections. They are given out at meetings, conferences, trade shows, and other business-related events.

These cards are as long as standard playing cards, at 8.9 cm.

So, as you can guess, six arranged lengthwise are a visual representation of 50 cm.

6. 2X A Burpless Cucumber

Burpless cucumbers have fewer seeds and have a less bitter flavor than other varieties. They typically have thinner skins, making them more palatable and easier to eat without peeling.

Although they may vary in size, the difference is usually negligible, with most being approximately ten inches (25.4 cm) long.

So, 50 cm is comparable to two burpless cucumbers.

7. 4X A Beverage Can

Beverage cans are a popular choice for packaging a wide range of beverages, from soda and beer to energy drinks, due to their convenience. They have a symbolic pull-tab or stay-on tab.

The height of the standard beverage can is almost the same in many countries, including the United States, precisely 12.3 cm, excluding the tab or pull-ring on the top. 

So, 50 cm is as long as four such cans placed end-to-end.

8. 2X A No. 10 Envelope

Whether you’re sending business correspondence, personal letters, or invoices, chances are you will use a No. 10 envelope. Their standard size and professional appearance make them a practical choice for many situations.

These envelopes are 9.5 inches (24.13 cm) long, meaning two end-to-end are approximately 50 cm long.

9. 3.5X A No. 2 Pencil

No. 2 pencils are a versatile and widely used tool for writing, drawing, and test-taking. They’re the ones you used from elementary school through college to universities.

And if you can picture how long they are, you are well-placed to understand how long 50 cm is.

Each No. 2 pencil is about 7.5 inches (19 cm) long, and although they may vary depending on the manufacturer, the difference is usually minimal.

So, picture four pencils in a straight line end-to-end, then imagine cutting one at either end into half.

10. 2X A Basketballs Ball

A standard basketball, used in professional and most recreational play, has a specific size and dimensions, as regulated by governing bodies, including the NBA (National Basketball Association) and FIBA (International Basketball Federation).

It’s usually 24 cm in diameter, so two are only two centimeters shy of the 50 cm mark.

11. 10X A Softball

Softballs are used in softball, a fun and competitive sport that offers opportunities for physical activity, teamwork, and skill development.

Softballs usually have a diameter of ten cm, meaning five placed in a row touching each other are a perfect reference for 50 cm.

12. 2.5X A Size 5 Soccer Ball

Size 5 soccer balls are standard size for professional and adult soccer matches. They are suitable for players aged 13 and older.

Size 5 soccer balls typically have a diameter of about 8.8 inches (approximately 20 cm).

Therefore, you can envision three placed in a straight line end-to-end and then imagine cutting one into half at either end for a practical understanding of 50 cm.

13. 2.5X A Volleyball

You can also refer to the length of the basketball to get an impression of something 50 cm long. 

Volleyball balls are almost the same size as Size 5 soccer balls, so you use a similar approach to get a mental picture of that length.
