Things that are 18 inches long (How big is 18 inches?)

Let us have a look at these objects that are present around us and helpful to determine the size of 18 inches better.

1) Two Watch Straps

Watches come in all forms and shapes. While some look vintage and traditional, many can walk beside the latest trends. The watches are available in different colors and the material of the straps is also different. Some of them are designed with leather, steel, metal, and so on. The size of the watch straps is 9 inches each and hence if you can align two such watches in a line then the additive measurement of the length will account for 18 inches of measurement.

2) Back Scratchers

The back scratchers are generally long sticks with a plastic palm at the end of them. The object is used when there is an itch on your back and you can not reach out to the spot. These range between the size 17 inches to 22 inches and are useful for determining the size of 19 inches. Since the measurement of nineteen inches just lies in between 17 and 22 we can take this up as an example to describe the length of 19 inches approximately. You can even take a scale and determine the length of the object to be more precise.

4) 9 #12 Wood screws

The #12 wood screws are of the measurement of 2 inches. These are very useful for describing the length of 18 inches since whenever we look around we see screws. These are tiny and pointed pins that are used for adhering two pieces of wooden blocks together. The dimension of the #12 screws are 2 inches and you will be needing 9 of them in a straight row to determine the length of 18 inches. You may visit a hardware store to purchase screws as well.
