9 Common Things That are 9 Inches Long (with Pictures)

Measuring a length of 9 inches (in) is most accurate when using a ruler or measuring tape.

But what if you don’t have these tools handy? Or can’t access them? In such cases, you can estimate the length by comparing it to everyday objects, and sometimes with a bit of basic math.

In this post, we’ll explore 9 common household items that can help you visualize how long nine inches is.

How long is 9 inches?

Before we dive into our list, let’s get a clear picture of what 9 inches means. In the metric system, 9 inches is equivalent to 22.86 centimeters.

To visualize this length, imagine slightly less than the width of a standard sheet of paper, which is typically 8.5 inches wide.

For those who prefer more creative comparisons, picture two hamsters lined up nose to tail or the length of a new pencil before it’s been sharpened.

It’s also about the size of a small loaf of bread or the diameter of a regulation baseball.

How do you measure 9 inches with your hand?

To measure 9 inches using your hand, you can use the average length of your hand as a reference.

For most adults, the distance from the tip of your middle finger to the base of your palm is about 7 to 8 inches.

You can spread your fingers slightly to extend the length or add an additional finger’s width to get closer to 9 inches.

By visually estimating based on your hand size, you can approximate 9 inches without needing a ruler or tape measure.

9 Everyday Common Objects That Are 9 Inches Long

Now that we have a better idea of what 9 inches looks like, let’s explore some everyday household items that measure up to this length.

📦 Item	📏 Actual Measurement

1. Dollar Bill

The humble dollar bill, a staple in wallets across America, measures precisely 6.14 inches long.

While this falls short of our 9-inch mark, it provides a valuable reference point. Stack one-and-a-half dollar bills end to end, and you’ve got yourself 9 inches.

This comparison can come in handy when you need a quick measurement tool.

Interestingly, the width of a dollar bill is 2.61 inches. So, if you arrange three dollar bills side by side, you’d have very close to 9 inches as well. Who knew your wallet could double as a makeshift measuring tape?

2. Four Standard Bricks

Building materials might not be the first thing that comes to mind when thinking about household objects, but bricks are more common than you might think.

Whether they’re part of your home’s structure, lining your garden path, or serving as bookends, bricks are everywhere.

A standard brick measures about 8 inches in length. Line up four of these sturdy blocks, and you’ll have a stretch measuring 32 inches.

Divide that by four, and voila – you’ve got your 9-inch segment.

This nugget of information could prove helpful in DIY projects or home renovations.

If you’re ever stuck without a tape measure, grab a brick and do some quick math. It’s a handy trick that might just save you a trip to the toolbox.

3. Standard Lunch Plate

Picture your everyday lunch plate. The kind you use for sandwiches, salads, or a slice of pizza. Chances are, it’s hovering right around the 9-inch mark in diameter.

While plate sizes can vary, the standard lunch plate typically measures between 8.5 to 9.5 inches across.

This size is considered ideal for portion control, allowing enough space for a balanced meal without encouraging overeating.

They’re not just holding your food. They’re secretly doubling as a measurement tool right under your nose (or, more accurately, under your lunch).

4. Two iPhone 6

In our increasingly digital world, smartphones have become as common as keys or wallets. The iPhone 6, released in 2014, measures 5.44 inches in length.

While technology moves fast and newer models have different dimensions, the iPhone 6 remains a good reference point.

Place two iPhone 6 devices end to end, and you’ll have a length just shy of 11 inches. Remove about an inch from this setup, and you’ve got your 9-inch measurement.

This comparison is handy for the tech-savvy among us. If you’re trying to estimate the size of a gadget or accessory, thinking in terms of iPhone lengths can be a quick and easy method.

5. Ten One-pound Coins

Currency comes in handy once again for our 9-inch measurement, this time in the form of coins. Specifically, we’re talking about British one-pound coins.

Each of these hefty coins has a diameter of 23.43mm or about 0.92 inches.

Line up ten of these coins in a row, and you’ll have a stretch measuring 9.2 inches. It’s not perfect, but it’s impressively close to our 9-inch target.

While not everyone has access to British currency, this comparison showcases how everyday objects from around the world can serve as unexpected measuring tools.

It’s a reminder that standardized measurements connect us across borders in ways we might not always consider.

6. Three Soup Cans

Venture into your pantry, and you’re likely to find a treasure trove of cylindrical measurements. The standard soup can, a staple in many households, typically stands about 3 inches tall.

Stack three of these cans on top of each other, and you’ve created a teetering tower of exactly 9 inches.

This makeshift measuring stick could come in handy when you’re reorganizing your shelves or trying to figure out if that new appliance will fit in the kitchen corner.

Beyond their potential as impromptu rulers, soup cans remind us how standardized measurements play a crucial role in manufacturing and storage.

Their uniform size allows for efficient packing, shipping, and shelving – all thanks to careful adherence to specific dimensions.

7. Standard Small Pizza

Pizza lovers, rejoice! Your favourite food can now double as a measuring tool. A standard small pizza typically measures 8 to 10 inches in diameter, with 9 inches being a standard size.

This means that the next time you order a small pizza, you’re not just getting a delicious meal – you’re also receiving a perfect 9-inch circle.

Imagine using a pizza to measure the width of your TV screen or the length of your coffee table. It might not be the most practical method, but it’s certainly the tastiest!

The 9-inch pizza also serves as a reminder of how measurements impact our food choices. This size is often considered ideal for individual consumption, balancing satisfaction with portion control.

8. Standard Envelope

Rummaging through your desk drawer, you’re likely to come across another 9-inch wonder: the standard envelope.

These ubiquitous paper containers, used for everything from bills to birthday cards, typically measure 9.5 inches in length.

While it’s slightly over our 9-inch target, the envelope provides a handy reference point. If you need a quick 9-inch measurement, grab an envelope and imagine it just a smidge shorter.

Envelopes showcase how standardized measurements facilitate communication and commerce.

Their uniform size ensures they fit neatly in mailboxes and sorting machines, allowing for efficient processing of millions of pieces of mail each day.

9. Classic Vinyl Record

The classic vinyl record is a beloved item for music enthusiasts and vintage collectors. These discs of musical magic come in various sizes, but the most common is the 12-inch LP (Long-Playing) record.

While a 12-inch record exceeds our 9-inch measurement, it provides an easy reference. Imagine a record, then mentally reduce its diameter by a quarter.

That visualization will give you a pretty accurate 9-inch circle.

Vinyl records are experiencing a resurgence in popularity, making them an increasingly common household item once again.

Their standardized size not only ensures compatibility with record players but also creates an iconic visual symbol of music that transcends generations.
