8 Common Things That Are Around 11 cm Big
These everyday objects offer useful size comparisons:
- A compact wallet
- A small dessert plate
- A travel soap bar
- A small notebook
- A compact sunglasses case
- A short screwdriver
- A small pear
- A miniature serving bowl
Their dimensions depend on the design, brand, and type. Some examples may be slightly shorter or longer than 11 centimeters, so treat them as estimates.
1. A Compact Wallet 👛
A compact wallet can have a width or height close to 11 centimeters. Many small wallets are designed to fit inside a handbag or jacket pocket.
Why it makes a useful comparison
Wallets usually have flat edges, which makes measuring straightforward. Place the closed wallet on a table and measure its longest side.
A wallet measuring 110 mm across would be exactly 11 centimeters wide.
Wallet sizes vary
Cardholders tend to be smaller than traditional wallets. Larger designs may also exceed this measurement, especially when they include extra compartments.
Check the specific wallet if you need an accurate comparison.
2. A Small Dessert Plate 🍽️
Some miniature dessert plates have a diameter close to 11 centimeters. These small dishes are useful for serving sweets, snacks, or small portions.
How to compare it
Place the plate on a flat surface. Measure straight across the center, from one outer edge to the opposite edge.
This distance is called the diameter.
Plate sizes differ
Many regular dessert plates are much wider than 11 centimeters. However, miniature dishes and small condiment plates can come closer to this measurement.
Always measure across the widest part rather than around the rim.
3. A Travel Soap Bar 🧼
A travel-size soap bar may have a length close to 11 centimeters, depending on its shape and packaging.
Small rectangular bars are particularly easy to measure because they have relatively straight edges.
Why it works
Place the soap beside a metric ruler. Measure from one end to the other along its longest side.
If the bar reaches the 11 centimeters mark, it provides a direct comparison.
Soap bars come in different sizes
Hotel soaps are often quite small. Larger travel bars may be longer, while rounded designs can make the endpoints harder to judge.
Measure the soap itself rather than including its wrapper.
4. A Small Notebook 📓
A pocket notebook may have a height or width close to 11 centimeters. Compact notebooks come in many formats, making them useful for everyday size comparisons.
How to measure it
Close the notebook and place it on a table. Measure the height or width along one straight edge.
A side measuring 110 mm equals exactly 11 centimeters.
Notebook dimensions vary
Some pocket notebooks are narrower than this length. Others have a longer side that exceeds 11 centimeters.
The cover may also extend slightly beyond the pages, so use the outside dimensions when comparing the whole notebook.
5. A Compact Sunglasses Case 🕶️
Some small sunglasses cases measure around 11 centimeters along one side. This is more common with compact cases than with large hard-shell designs.
Why it is easy to compare
A sunglasses case usually has a clear length or width. Place it on a flat surface and measure from one end to the other.
For rounded cases, use the straight-line distance between the outermost points.
Case styles differ
Slim cases may be longer than they are wide. Hard cases can also have a different shape from soft fabric pouches.
Check the actual dimensions rather than assuming every case has the same size.
6. A Short Screwdriver 🪛
A small precision screwdriver can have an overall length close to 11 centimeters. These tools are commonly used for minor repairs and small household projects.
How to compare it
Lay the screwdriver beside a ruler. Measure from the back of the handle to the very tip.
Include both the handle and shaft for the total length.
Tool sizes vary
Some precision screwdrivers are shorter than 11 centimeters. Others have longer shafts or thicker handles.
A compact model is the best choice for this comparison.
7. A Small Pear 🍐
A small pear can approach 11 centimeters in length, although many fruits are shorter or wider.
Its natural shape makes it a convenient household object to measure.
Why it helps
Place the pear beside a ruler and measure from the stem end to the bottom. Use the straight-line distance rather than following the curve of the fruit.
A longer pear may come close to the 11 centimeters mark.
Fruit sizes are not consistent
Pear varieties differ in shape and size. Some are short and round, while others are long and narrow.
For that reason, measure the individual fruit instead of relying on its variety alone.
8. A Miniature Serving Bowl 🥣
A small serving bowl may have a rim diameter close to 11 centimeters. These dishes are sometimes used for dips, sauces, nuts, or small snacks.
How to measure it
Place the bowl on a flat surface. Measure across the opening from one outer rim to the opposite rim.
This gives you the bowl’s diameter.
Bowl dimensions differ
Some condiment bowls are much smaller than 11 centimeters. Others are wider, depending on their intended use.
The opening is also different from the base, which is often narrower.
How Big Is 11 cm in Millimeters?
Converting centimeters to millimeters is simple.
One centimeter contains 10 millimeters.
Therefore:
11 × 10 = 110 mm
So, 11 cm equals exactly 110 millimeters.
