Figuring out how long is 16 inches can be difficult and confusing because it’s one of the measurements that sounds simple, but without tangible to compare it to, it can be difficult.
And having an image of how long 16 inches is comes in handy for everyday situations, whether you’re shopping for furniture, picking out something, or choosing the hair extension length.
So, how long is 16 inches, it’s about 1 1⁄3 feet or around 40.64 centimeters.
It is longer than a standard 12-inch ruler but you have to add another 4 inches for the 16 inches.
I find it easiest to visualize using common objects like a laptop screen, a large pizza, or the distance from your elbow to a past your wrist.
Here in this post, I’m gonna walk you through everyday items of how long is 16 inches.
I’ll break down how this measurement affects the human body, convert it to other units you need, and answer common questions.
How Long is 16 Inches Compared to an Object? (16 Best Common Objects to Consider)
Standard Laptop Screen
My laptop has been the reference for 16 inches.
Standard laptop screens are measured diagonally from corner to corner, and many modern laptops are around the 15-16 inch range.
So take your laptop, imagine a line from the bottom left to top right corner, and it is 16 inches.
But remember that manufacturers measure the screen, not the laptop body.
And some say that “16-inch laptops” measure 15.6 or 16.4 inches.
16-Inch Pizza
A 16-inch pizza is what pizza places call their “large” or “family” size.
That measurement refers to the diameter, the straight line across the middle of the pizza.
What’s funny is that a 16-inch pizza gives you more pizza than you think.
While a 12-inch medium pizza has 8 slices, a 16-incher comes cut into 10-12 slices and has twice the area.
Bass Guitar Neck
The neck of a standard bass guitar measures about 16 inches from the nut to around the 12th fret.
I noticed this while watching my brother play bass last summer.
The catch here is that different bass guitar models vary, and some custom or extended-range basses have longer necks.
But standard 4-string bass guitars stick to this measurement.
Throw Pillow
I’ve square throw pillows on my couch that measure 16×16 inches which is standard size for pillows.
They’re not too big, not too small but right for both decoration and comfort.
What’s best about using a throw pillow is that you can easily grab it and hold it up to visualize the measurement.
The edges are defined, it is not like some other objects with curved surfaces.
Car Steering Wheel
Most standard car steering wheels measure about 16 inches in diameter.
It’s something most of us interact with but rarely think about in terms of size.
Different car makes and models vary like sports cars have small wheels while trucks have large ones.
But the average family car is around 16 inch.
Five Credit Cards
If you line up 5 standard credit cards end to end, they’ll measure exactly 16 inches.
Because each card is 3.37 inches long, five of them come to 16.85 inches and it is around 16 inches.
The great thing about this comparison is that people have at least one credit card, debit card, or ID card with the same dimensions.
They’re also manufactured to the same measurements, so they’re more reliable than handmade objects.
Backpack
Most standard school or day-trip backpacks measure about 16 inches from top to bottom.
I checked my own everyday backpack, and it’s around 16 inches.
Keep in mind that backpacks come in many different sizes, and some expand when full.
Also, measuring can be difficult with all the pockets and curved surfaces.
But, that main compartment on an adult backpack is close to 16 inches.
Chain
A 16-inch chain or necklace is one of the common lengths.
It falls at the collarbone or below for most adults. I wear a 16-inch silver chain, and it is perfectly at my collarbone.
What complicates using chains as measurement references is that they’re flexible, so you need to make sure you’re measuring them fully extended but not stretched.
Also, the clasp adds extra length.
Cutting Board
Check your kitchen and chances are there that at least one of your cutting boards is around 16 inches in length.
The standard rectangular cutting board measures about 16×12 inches, the longer side a reference.
What’s great about cutting boards is that they’re rigid and have clear edges, making them easy to visualize.
But be sure you’re looking at the longer side of the rectangle.
Two Standard Bricks
Here’s something I noticed while helping my dad with a garden: two standard bricks placed end to end measure about 16 inches.
A brick is around 8 inches long, two of them create our measurement perfectly.
The nice thing about bricks is their consistency, they’re manufactured to standard sizes for construction purposes.
However, different countries are different brick size standards, and there are bricks that differ from the norm.
But the red clay brick is equal to 16 inches.
Microwave Oven
The width of a standard countertop microwave is close to 16 inches.
I measured mine and it’s 16.5 inches.
Microwaves vary more than some other items on this list, with compact models measuring smaller and over-the-range models large.
But the mid-size countertop model is around 16 inches across the front.
Width of 2 A4 Sized Paper
Two sheets of standard A4 paper placed side by side give you 16.54 inches, a hair over 16 inches.
Since most of us have printer paper available, this makes for an accessible comparison.
A4 paper is the standard in most countries outside North America.
Each A4 sheet measures 8.27×11.69 inches, so we’re using the width measurement.
If you’re in the US with Letter paper, two sheets would give 17 inches, over 16 inches.
16 Paper Clips
Line up 16 standard paper clips end to end, and it is approximately 16 inches.
Each paper clip is about an inch long, making this an easy way to visualize the measurement using common office supplies.
Paper clips come in different sizes, so this works best with the standard small ones we all have cluttering up our desk drawers.
The jumbo clips are longer measurements.
Three Envelopes
Three standard business envelopes placed side-by-side measure close to 16 inches.
Each envelope is around 9.5 inches wide and 4.125 inches tall, so using the width, you’d need under two envelopes to reach 16 inches.
Three envelopes using the height dimension gets you to 12.375 inches.
Two Standard Pencils
Two unsharpened standard pencils placed end to end close to 16 inches.
A new pencil measures around 7.5 inches long, so two of them give you 15 inches, an inch low to 16 inches.
I like this comparison because pencils are so common and uniform.
But remember that pencils get shorter as you sharpen them, so this works best with new pencils.
Stacked Smartphones
Three average smartphones stacked end to end will measure close to 16 inches.
Many modern smartphones are around 5.5-6 inches long, so three of them together are between 16.5-18 inches.
The tricky part here is that phone sizes vary between models.
My iPhone 12 is different from my husband’s Samsung Galaxy. Plus, with phone sizes changing with each generation, this comparison may not stay accurate for long
How Big is 16 Inches Compared to a Human?
So how does 16 inches relate to your body? For most adults, 16 inches is:
- Longer than your forearm
- About the width of your shoulders
- Roughly the length from your wrist to a few inches past your elbow
- Shorter than the length of your foot to your knee
I’ve found that the forearm comparison is the most useful for estimates.
Hold out your arm, measure from your elbow to your wrist, and then imagine extending further.
How Long is 16 Inches in Feet?
Converting 16 inches to feet is straightforward. Since there are 12 inches in a foot:
16 inches ÷ 12 = 1.33333… feet
So 16 inches equals 1⅓ feet (or 1 foot and 4 inches).
Conversion of 16 Inches to Other Measurements
You need to convert inches to other measurement units.
Here’s a handy reference table I put together:
| Unit | Conversion Value |
| Feet | 1.333 feet |
| Centimeters | 40.64 cm |
| Millimeters | 406.4 mm |
| Meters | 0.4064 m |
| Yards | 0.444 yards |
| Kilometers | 0.0004064 km |
| Miles | 0.000252 miles |
I always find the centimeter conversion useful because many products list their dimensions in both imperial and metric measurements.
