Eight inches is two-thirds of a foot, or approximately 0.67 feet. There are 12 inches in one foot, so divide 8 by 12.
This is handy when comparing smaller dimensions with measurements given in feet.
How Big Is 8 Inches in Real Life?
A length of 8 inches is about the length of a small kitchen tool or a compact handheld device. It is easy to picture when you compare it with a photo print, a wrench, or a tablet’s body dimensions.
Keep in mind that an item’s advertised size does not always describe its entire length. A chef’s knife, for example, is often named by its blade length, while a frying pan’s size usually refers to its top diameter.

10 Common Examples of Objects That Are 8 Inches Long
1. An 8 × 10-Inch Photo Print
An 8 × 10-inch photo print has a shorter side measuring exactly 8 inches when cut to the stated dimensions.
Place the print on a flat surface and look at its shorter edge. That edge gives you a clear, straight reference for the length.
Photo prints can be useful for visual comparisons, but check the actual print dimensions if it has a border or has been trimmed.
2. Chef’s Knife Blade
An 8-inch chef’s knife blade is a common size for kitchen knives. The measurement refers to the blade, not the full knife from tip to handle end.
A knife with an 8-inch blade will usually be longer overall once its handle is included.
If you are comparing knives, check whether the listed measurement refers to the blade alone or the entire knife.
3. Adjustable Wrench
An adjustable wrench sold as an 8-inch model is generally described by its nominal overall length. The actual measurement can vary slightly by design and manufacturer.
This size is commonly used for household repairs and general maintenance. The adjustable jaw allows the tool to grip different nut and bolt sizes.
If you need an exact 8-inch reference, measure the particular wrench from end to end rather than relying only on its product label.
4. Volleyball
A regulation volleyball is roughly 8 inches across, although its exact diameter depends on its circumference and construction.
The official circumference range for an indoor volleyball works out to a diameter of approximately 8.1 to 8.4 inches.
That makes a volleyball a helpful near-match, but it should be treated as an approximate comparison rather than an exact 8-inch object.
5. Nintendo Switch Lite
The Nintendo Switch Lite is approximately 8.2 inches long. Its overall length is slightly greater than 8 inches.
Because it is a handheld gaming system, it can help you visualize a length close to 8 inches when held horizontally.
Remember that the device’s length is different from its screen size, which is measured diagonally.
6. iPad mini
The iPad mini’s body height is approximately 7.69 inches when held in portrait orientation. That makes it a little shorter than 8 inches.
Apple also describes its display as 8.3 inches diagonally. The diagonal screen measurement is not the same as the height of the device.
For an accurate comparison, decide whether you want to compare the tablet’s body height or its screen diagonal.
7. Standard Brick
A common modular brick is about 7⅝ inches long, making it slightly shorter than 8 inches.
Brick sizes vary by country, type, and manufacturer, so this is best used as a near-match rather than a precise measuring reference.
If you are working on a building project, use the stated dimensions of the actual brick instead of assuming every brick is the same size.
8. Kitchen Scissors
Many household kitchen scissors are around 8 inches long from tip to handle end, although smaller and larger designs are available.
Their overall length makes them a practical object to compare with an 8-inch measurement.
For a more reliable estimate, place the scissors on a flat surface and measure from the tip to the farthest point of the handle.
9. Drinking Straw
A standard drinking straw may measure around 8 to 8.25 inches, depending on its intended use and manufacturer.
A straw close to this size can give you a quick visual estimate of 8 inches. However, disposable, reusable, and specialty straws come in different lengths.
Measure your own straw if you need an exact result for a craft or DIY project.
10. Small Frying Pan
An 8-inch frying pan is usually named for its approximate top-rim diameter, not its height or the diameter of its flat cooking surface.
The cooking area may be smaller because the sides curve inward. The outside dimensions can also differ between models.
For comparison, measure straight across the top of the pan from one rim edge to the opposite edge.

Which Objects Are Exactly 8 Inches?
Only use an object as an exact reference when its stated dimension really is 8 inches. Items described by a nominal size or an approximate length should be treated as close comparisons.
| Object | Stated size | Measurement |
|---|---|---|
| 8 × 10-inch photo print, shorter side | 8 inches | Exact |
| Chef’s knife blade | 8 inches | About |
| Adjustable wrench | 8 inches | About |
| Volleyball | Around 8.2 inches | About |
| Nintendo Switch Lite | Around 8.2 inches | About |
| iPad mini body height | Around 7.69 inches | About |
| Standard brick | Around 7⅝ inches | About |
| Kitchen scissors | Around 8 inches | About |
| Drinking straw | Around 8–8.25 inches | About |
| Small frying pan, top diameter | Nominal 8 inches | About |
How Long Is 8 Inches on a Ruler?
To find 8 inches on a standard ruler, start at the zero mark and count to the large line labeled 8. The distance from zero to that mark is exactly 8 inches.
If your ruler is only 6 inches long, mark the 6-inch point first, then measure another 2 inches from that mark. Together, the two measurements equal 8 inches.
Make sure the object’s starting edge lines up with zero. Starting at the physical edge of a ruler instead of its zero mark can lead to a small measuring error.
How Can You Measure 8 Inches Without a Ruler?
If you do not have a ruler nearby, compare the length with an object whose dimensions you already know. An 8 × 10-inch photo print can help if it has been trimmed accurately, while a kitchen tool may offer a rough estimate.
You can also use a piece of paper: mark a starting point, transfer a known measurement, and add the remaining distance. This is less reliable than using a ruler, so treat the result as an estimate.
For projects that require accuracy, use a ruler or tape measure rather than relying on memory or hand size.
How Long Is 8 Inches of Hair?
Eight inches of hair is about 20.32 centimeters measured along the strand. It can represent a noticeable amount of growth, but how it looks depends on the starting length, haircut, and hair texture.
Straight hair usually shows its full measured length more clearly. Curly or coily hair may appear shorter because the strands curl or shrink when dry.
If you are tracking hair growth, measure a strand from the root area toward the ends in a consistent way. Avoid comparing stretched hair with unstretched hair, since the visible length can differ.
Is 8 Inches Considered Long?
Whether 8 inches is considered long depends on what you are measuring. For a kitchen knife blade, it is a common size; for a handheld electronic device, it is relatively long; for a piece of hair, it can be a substantial length.
The most useful comparison is the object’s intended dimension. For example, an 8-inch frying pan refers to its top diameter, while an 8-inch knife refers to the blade length.
What Is the Difference Between 7 Inches and 8 Inches?
The difference between 7 inches and 8 inches is exactly 1 inch, or 2.54 centimeters.
Eight inches is about 14.3% longer than 7 inches. When comparing objects, this difference can be easier to see if you line them up at the same starting point.
Is 8 Inches Bigger Than 20 Centimeters?
Yes. Eight inches equals 20.32 centimeters, which is 0.32 centimeters longer than 20 centimeters.
The difference is small, but it matters when a measurement needs to be accurate.
