Comparing the length of known objects with objects you want to measure is helpful when you don’t have a ruler or tape measure. 6.5 inches may be a slightly unusual length, but there are some household items that are similar in size.
So, how big is 6.5 inches? 6.5 inches is as big as a toothbrush, pencil, hot dog, ballpoint pen, door handle, pair of scissors, and many other objects. I will give you a list of items that measure 6.5 inches.
These items will help you measure the unknown length of other objects. Let’s begin.
18 Items That Are 6.5 Inches
I have compiled a list of 18 items. These items are exactly 6.5 inches or about 6.5 inches. You will get an idea about how big 6.5 inches is considering the items visually.
1. A Smartphone

Compared to when smartphones were first launched, modern-day smartphones have bigger screens. In most smartphones, you will find a 6.5-inch screen. For example, smartphones from Apple or Samsung will have this screen size.
You have to measure the screen diagonally to get the screen size. Measure from any of the top corners to the opposite bottom corner. The length should be exactly 6.5 inches or close to it.
2. A Dollar Bill

The dollar bill in your pocket might be a great way to measure objects that are 6.5 inches long. All dollar bills in the US are of the same size regardless of the denomination. Be it a one-dollar bill or a hundred-dollar bill, the length of the bill is 6.1 inches.
Even though that is slightly lower than our desired length, it is close to 6.5 inches. For rough measurement ideas, the dollar bill will be a good tool.
3. A Toothbrush

This is one of the most common things in our households, and we use it once or twice a day. The length of a regular toothbrush is about 6.5 inches. In metric units, that is about 16.5 cm.
I am talking about traditional toothbrushes for adults. Baby toothbrushes might be smaller. If you have electric toothbrushes, they might be a bit longer. The length might also vary for toothbrushes from different brands.
4. A Hotdog

Standard hotdogs are about 6-6.5 inches long. You might also get longer hotdogs, but I am talking about the most common size.
The sausage on the hot dog might be a bit shorter. So, it is better to consider the length of the hot dog bun, which is almost 6.5 inches.
5. A Pizza

Small pizzas are great for individuals. If you are eating alone, a small pizza of 6-6.5 inches should suffice. Even though pizzas don’t actually have lengths, you can assume the diameter as a length.
To measure the diameter, you should imagine a line through the center and two opposite points on the edge. This line will measure about 6.5 inches on a small pizza.
6. A Pencil

The length of a new pencil will be about 6.5 inches. The length of the pencil may vary depending on the brand. Its length also depends on whether the pencil has an eraser on the back.
This is for wooden pencils. Mechanical pencils might also be of a similar size in many cases.
7. A Butter Knife

Butter knives are used to spread butter or other soft items on your bread or toast. These knives are smaller than regular kitchen knives. Such a butter knife will measure about 6.5 inches in length.
These knives don’t usually have wooden or plastic handles. So, you need to consider the whole knife including the handle part.
8. A Small Zip Tie

Regular-size zip ties are commonly used in electric works. But, there are smaller versions of zip ties that are used for indoor cable management. For example, the cables inside your PC or behind the table can be managed with smaller zip ties. Such a zip tie will be about 6-6.5 inches long.
9. A Side Plate

Side plates are smaller than regular plates. We use these plates to serve snacks, bread, or other small items. The diameter of a side plate is about 6.5 inches. To be more specific, the diameter can be 6 or 7 inches.
Of course, there are size variations. However, the average diameter will be close to 6.5 inches, regarding the plate material.
10. A Paint Brush

You might have seen small paintbrushes in your household. These paintbrushes usually have a brush width of one or two inches. With the long handle to hold the brush, the overall length of such a brush is about 6.5 inches.
If the width of the brush increases, the length may vary. Small roller brushes with plastic handles might also have a length of 6.5 inches.
11. A Small Water Bottle

Smaller water bottles are more convenient for carrying around. If you have a small water bottle of 300 or 500 ml, measure its length. The length of the bottle should be about 6.5 inches.
Remember, the length of the bottle might depend on the design, brand, etc. However, it is enough to give you a rough idea of how big 6.5 inches is.
12. A Ballpoint Pen

Many different types of pens are available out there, including ballpoint pens, fountain pens, etc. If you take a regular ballpoint pen, it will be about 6.5 inches in length.
The length includes the cap. If you take the cap off, the length of the pen might be shorter.
13. A Soup Bowl

It is another common utensil in our households. The diameter of a regular soup bowl should be about 6.5 inches. You might also have curry bowls of this size.
Measure two points on the edge of the bowl while keeping the center point on the line. This will give you approximately 6.5 inches.
14. An Electronic Stove Lighter

These small tools are highly helpful to ignite gas stoves while keeping your fingers safe. The length of an electronic stove lighter will be 6.5 inches. I am talking about lighters with a small holding point and a large switch to press down.
Some lighters have triggers like pistols and have longer barrels. Those lighters will be about 12 inches long.
15. A Bamboo or Metal Skewer

If you love kebabs, skewers must be available at home. These small rods made of metal or bamboo are really useful for making kebabs. The length of these skewers is about 6.5 inches.
Some skewers are much larger and let you grill a lot of meat or veggies at once. Those skewers are usually longer than 1 foot. Take small skewers that fit onto side plates, and they will give you an idea of how big 6.5 inches is.
16. A Grinder Jar

Various sizes of grinder jars are available out there. So, it might be a bit tricky to find a grinder that measures 6.5 inches. Take a small grinder jar with a volume of 500 ml. The height of this jar should be about 6.5 inches.
Remember, I only told the grinder jar. Don’t put the jar on the grinding machine and measure the height. Otherwise, you might curse me.
17. A Small USB or Ethernet Cable

Longer USB cables are commonly used for charging devices from wall outlets. But there are some short USB cables that we use to transfer data between devices. These USB cables are about 6.5 inches long.
You might also find some ethernet cables that are this long. These cables are often used to connect devices that are close to each other.
18. A Door Handle

Be it the door of your room or a kitchen cabinet, you might use different types of handles. These metal handles are often about 6.5 inches long. Old-style handles are a bit shorter. You should take modern handles that have a long part with two offset short parts. The length of the longer part is about 6.5 inches.
Conclusion
Can you make someone understand the length of an object without showing them the object? Yes, that is possible when you tell them about the length of other objects they know about. So, when you ask how big is 6.5 inches, the same strategy is good enough to make you understand.
I provided a list of household items that measure 6.5 inches in length. As we use these items in everyday life, the length perception is easier for us. Once we get the idea, we can use that perception to assume the length of other objects.
