Understanding the length of 20 inches can help us visualize the dimensions of things and appreciate their scale.

**In simple terms, 20 inches is equivalent to 50.8 centimeters or approximately 1.7 feet.**

Now that we have a grasp of its numerical value, let’s dive into the realm of things that measure 20 inches in length

## List Of Things That Are 20 Inches Long:

- Two size nine shoesÂ
- Standard Length Of 5-Â½ Crayons

## 1. Three Surgical Mask:

Surgical masks are commonly available and measure around 7 inches in width. If you use three surgical masks to measure something, it would come out to about 20 inches, minus 1 inch from either end.

## 2. Nine Standard Nail Clippers:

Nail clippers are a tool for trimming fingernails and toenails. They have a base that is around 2.25 inches long and holds one or two attachments. This is about the same length as a slim soda can. You can use nail clippers to measure small distances.

For example, to measure 20 inches, you would need nine nail clippers with the attachments folded into the base. So, nail clippers are a helpful tool for measuring small things

## 3. iPhone 13 Pro:

If you have an iPhone 13 Pro measuring 20 inches might not be hard. The phone is 5.78 inches tall, so if you put 4 of them next to each other, it would be about 23 inches.

You just need to take away 3 inches. You can take reference from 3 inches long things.

If you have an iPhone 13 Pro Max, it is 6.33 inches tall. If you put 3 of them next to each other, it would be almost 19 inches. Which is just 1 inch shy of 20 inches but it can give you a good idea of about 20 inches in length.

## 4. Length Of Two BasketBall:

Basketballs come in different sizes for different age groups and genders. A size 7 basketball, which is what they use in NBA games, is 9.5 inches wide and weighs 22 ounces when fully pumped.

If you put two of these basketballs side by side, you’ll get a length of about 20 inches, but there will be a one-inch gap between them. It’s not hard to imagine this gap in your mind.

## 5. Length Of 2 Forearms:

If you don’t have a ruler handy for measuring the length of an object, fret not! You can use your forearms as a rough reference. While it’s ideal to measure your forearm first if you’re unaware of its length, the average forearm length of approximately 10 inches can be used as an estimate.

If you’re aiming for a 20-inch length, visualize placing two forearms end-to-end next to the object you’re measuring. This should give you a decent approximation of the length without the need for a ruler.

## 6. 8 Soda Can:

Soda cans are cylindrical containers made of aluminum or steel that hold carbonated beverages, such as soda, energy drinks, and sparkling water.

They are typically 4.83 inches (12.3 cm) in height and 2.6 inches (6.6 cm) in diameter and can hold 12 fluid ounces (355 ml) of liquid. So, 8 soda cans would be approximately 96 fluid ounces (2.83 liters) in total.

## 7. Two Steak Knives:

Steak knives are knives used to cut steak and they come in different sizes and shapes. They are usually 7-9 inches long. If you have two steak knives that are 10 inches each, they add up to 20 inches.

If you only have shorter 7-inch steak knives, you can still measure 20 inches by placing three of them lengthwise and subtracting an inch.

## 8. Two 9 Size Shoes:

Shoe sizes can be different depending on the brand, even if they’re both labeled as size 9. In the US, most size 9 shoes are usually between 9.5 and 10.5 inches long. If you want a 20-inch shoe, you’ll need two pairs of size 9 shoes on average.

But sometimes, the actual size of the shoes can affect the final measurement, so you might need to make small changes to get to exactly 20 inches. However, to fit the 9-size shoe the shoebox must be a few inches larger than the actual measurement of the shoes.

## 9. Standard Length Of 5-Â½ Crayons:

A typical, fresh-out-of-the-box crayon measures approximately 3.6 inches in length from one end to the other.

So, if you were to gather 5 and a half of your child’s unused crayons and lay them down flat, they would span a total length of almost exactly 20 inches.Â

## 10. 18 Quarters:

The diameter of a quarter-dollar coin, as stated by the United States Mint, is 1.205 inches. If you were to lay out 18 quarters side by side from your pocket or wallet, it would measure approximately 21.69 inches in length. However, if you imagine erasing one inch from the total length, it would equate to roughly 20 inches.

On the other hand, if you only had pennies with a diameter of 0.75 inches each, you would need almost 27 of them to measure up to 20 inches.

## 11. 3 Standard Soup Spoons:

Soup spoons are a bit different from other spoons because they have a deeper, rounder bowl. The average size of a soup spoon is about 6 inches to 7 inches. If you put three of them together, they would be almost 20 inches long.

## 12. Length Of 5 Menâ€™s Wallet:

Â A popular size for men’s wallets that are intended to be carried in the back pocket is approximately 4 inches in length when folded over. This makes them a convenient reference point for objects that are also around 4 inches in length.

For instance, if you were to line up 5 of these wallets side by side, the total length would be about 20 inches
