If you are estimating or comparing the length of something, it can be difficult to figure out exactly how long 20 inches actually is.

**20 inches is equal to 50.8 centimeters or 508 millimeters.**

**20 inches is also 4 inches less than 2 feet.**

## 1. 20 Water bottle caps

Depending on the size of the bottle, the caps can vary in size.

One of the most common water bottle sizes is 500 ml which can be purchased at local stores as a single bottle or in large packs.

Each one of the bottle caps on these bottles will measure close to 28 millimeters in diameter which is about 1 inch.

If you can imagine 20 of these bottle caps together in a row, they would equal around 20 inches long.

## 2. 6 Crayons

The crayon is a popular drawing and coloring tool made out of wax and commonly used by children in schools.

Each crayon measures 3.5 inches long. Placing 6 crayons together would equal just over 20 inches long.

## 3. A Back scratcher

As we all know, it can be difficult to reach certain areas of your back to scratch an itch unless you have a tool to extend your reach.

A back scratcher is made for this purpose.

Back scratchers vary in size and there are a variety of types to choose from.

Most adults prefer to use a back scratcher that is around 20 inches in length.

## 4. A Shoehorn

You wouldn’t think of a shoehorn being as long as 20 inches but they actually are quite common.

Most normal-sized shoe horns are around 4-8 inches long.

But a long-handled shoe horn can be 20 inches long and in some cases even longer.

## 5. 10 Soda cans

Like many types of soda cans and bottles, they can vary in size and shape.

Looking at an example of a common 355 ml can of soda, they will each have a diameter of 2.13 inches across the top of the can.

So although it is not exactly 20 inches long, if you picture 10 of these soda cans standing up together in a row, they will equal very close to 20 inches long across the top.

## 6. 3 iPhone 12 Max Pro

In an October 13, 2020 press release, Apple introduced the iPhone 12 Max Pro.

This phone has become quite popular and with all the new features and upgrades, I can see why.

One of the most important features for cell phone users is the size.

The iPhone 12 Max Pro is 6.33 inches long.

So if you are lucky enough to have 3 of these phones, placing them together would give you an idea of 20 inches in length.

## 7. 5 Men’s wallets

The size of a wallet can vary and can be used for different purposes.

A typical men’s wallet that would fit in your back pocket will be around 4 inches long when folded over.

These wallets are very common and are a great item to use for referencing something that is 4 inches long.

If you had 5 men’s wallets lined up together, they would equal 20 inches long.

## 8. 3 Soup spoons

Soup spoons are somewhat similar in size to other types of spoons with the exception being the round bowl part of the spoon is deeper.

An averaged size soup spoon measures around 6 or 7 inches therefore 3 of them together would equal close to 20 inches in length.

## 9. 8 Tennis balls

In order for a tennis ball to be used during a professional match, it must be a certain size.

According to the International Tennis Federation, a tennis ball must be between 2.57 and 2.70 inches in diameter.

You would need to have 8 tennis balls placed together in a row to measure just over 20 inches long.
