8 Common Things That Are Around 17 cm Big
Here are eight everyday objects that can help you estimate this size:
- A dinner fork
- A standard pencil
- A small paperback book
- A compact hairbrush
- A table knife
- A small kitchen spatula
- A handheld TV remote
- A travel-size toiletry bottle
These are approximate examples, not fixed measurements. Some items may be shorter or longer depending on their design and manufacturer.
1. A Dinner Fork 🍴
A dinner fork is a familiar item that may measure close to 17 cm from the end of its handle to the tips of its prongs. You can find one in almost any kitchen.
How to measure it
Place the fork on a flat surface beside a ruler. Measure from the bottom of the handle to the farthest tip.
This gives you the fork’s total length.
Why the size can vary
Some dinner forks have short handles, while others are longer. Decorative designs may also change the overall dimensions.
Use a fork that measures close to the target rather than assuming every utensil is the same size.
2. A Standard Pencil ✏️
A full-length wooden pencil can be a useful reference for estimating a length around 17 cm. However, pencils vary in size, and some standard models are shorter.
How to compare it
Place the pencil beside a ruler. Measure from the eraser end to the sharpened tip.
For the most consistent result, measure the pencil as it is rather than estimating from its appearance.
Keep pencil size in mind
New pencils are generally longer than well-used ones. Sharpening also reduces their length over time.
A full-size pencil may come close to this measurement, making it a convenient item to check at home.
3. A Small Paperback Book 📚
A compact paperback book may have a height or width close to 17 cm. Small novels, pocket guides, and travel books can provide useful examples.
How to measure it
Close the book and place it on a table. Measure the front cover along its height or width.
Choose the side that comes closest to the desired length.
Book formats differ
Some paperbacks are tall and narrow. Others have wider covers, while pocket editions tend to be smaller.
Check the cover itself to see whether one side measures near the target.
4. A Compact Hairbrush 💇
A small hairbrush can have an overall length close to 17 cm. Compact brushes are convenient for handbags, gym bags, and travel kits.
How to measure it
Lay the brush flat. Measure from the bottom of the handle to the farthest edge of the brush head.
This gives you the full length of the item.
Brush designs vary
Foldable brushes have different dimensions when open and closed. Larger styling brushes may also be considerably longer.
A compact travel brush is the most suitable version for this comparison.
5. A Table Knife 🔪
Some table knives measure close to 17 cm from the handle’s end to the tip of the blade. Their long shape makes them easy to compare with a ruler.
How to measure it
Place the knife carefully on a flat surface. Measure its entire length, starting at the end of the handle and finishing at the blade tip.
Keep your fingers away from the sharp edge while measuring.
Knife sizes differ
Butter knives, dinner knives, and serving knives come in various lengths. A compact table knife may be closer to the target than a larger dinner knife.
Always check the actual utensil before using it as a reference.
6. A Small Kitchen Spatula 🍳
A compact kitchen spatula may measure around 17 cm from end to end. Small silicone spatulas are useful for mixing ingredients, scraping bowls, and spreading toppings.
How to compare it
Lay the utensil beside a ruler. Measure from the end of the handle to the farthest edge of the blade.
This gives you the full length, not just the handle measurement.
Choose the right type
Full-size cooking spatulas are often much longer. Miniature baking and serving tools are more likely to provide a close comparison.
The material and handle design can also affect the overall size.
7. A Handheld TV Remote 📺
Some compact television or streaming-device remotes have a length close to 17 cm. Their narrow shape makes them simple to measure.
How to measure it
Place the remote flat on a table. Measure from the top edge to the bottom edge, including the casing.
This gives you the device’s total length.
Remote dimensions vary
Standard television remotes can be longer, while small streaming remotes may be shorter. Button layouts and device types also affect their size.
Check your particular remote for a reliable comparison.
8. A Travel-Size Toiletry Bottle 🧴
Some travel-size toiletry bottles stand close to 17 cm tall. These containers are common in travel bags and bathroom cabinets.
How to compare it
Stand the bottle upright on a level surface. Measure from its base to the top of the cap or pump.
Include the closure when checking the full height.
Bottle shapes make a difference
Narrow bottles may be taller than short, wide containers with a similar capacity. Packaging also varies between brands.
Measure your bottle instead of relying on its advertised category alone.
How Big Is 17 cm in Millimeters?
One centimeter equals 10 millimeters.
Multiply 17 by 10:
17 × 10 = 170 mm
Therefore, the exact conversion is 170 millimeters.
How Big Is 17 cm in Inches?
One inch equals 2.54 centimeters.
Divide 17 by 2.54:
17 ÷ 2.54 ≈ 6.69
So, the measurement is approximately 6.69 inches. That is a little longer than 6½ inches.
How Big Is 17 cm in Feet?
One foot contains 12 inches.
Since 17 cm equals approximately 6.6929 inches:
6.6929 ÷ 12 ≈ 0.5577
Therefore, the length is approximately 0.558 feet.
How Big Is 17 cm in Meters?
There are 100 centimeters in one meter.

17 − 15.24 = 1.76 cm
That means the target length is 1.76 cm longer than 6 inches.
Is 17 cm Close to 7 Inches?
Yes. Seven inches equal 17.78 cm.
The difference is just 0.78 cm, or 7.8 millimeters. Seven inches is therefore a useful rough comparison, although it is slightly longer.
Is 17 cm Twice as Long as 8.5 cm?
Yes. Two lengths of 8.5 cm add up to 17 cm.
This makes it easy to divide the measurement into two equal halves.
Is 17 cm the Same as 170 mm?
Yes. Each centimeter contains 10 millimeters, so the conversion is exact.
17 cm = 170 mm.
How Can You Estimate This Length Without a Ruler? 📏
A ruler is the best choice for accuracy. If you do not have one nearby, familiar objects can help you make a rough estimate.
Use a Full-Length Pencil
A new pencil may come close to this length. Compare it with the item you want to estimate.
Check a Dinner Fork
Some dinner forks have a similar overall length. Lay one flat to make a side-by-side comparison.
Try a Compact Hairbrush
A small brush can provide another reference. Measure it first if you want to use it for future estimates.
These methods are only approximate because everyday products vary in size. Use a metric ruler or measuring tape whenever precision matters.
