Difference Between Length and Width

By: | Updated: Jul-10, 2021

There are many different types of measurements that are commonly used in math, but the two most common are length and width. Both of these measurements are used to describe an object, but there are some differences between them. For example, length is the distance from one end to the other, while width is the distance from one side to the other. Also, length is a three-dimensional measurement, while width is a two-dimensional measurement. So what are the other differences between length and width?

The article will focus on the length and width, the difference between length and width, the terms related to length and width, and how they are used in math.

Difference Between Length and Width

What Is length?

Length is the distance from one end of an object to the other. Length is measured in units called “meters” or “feet”. The units used to measure length depend on what you are measuring. If you are measuring something very small, like a single atom, you will use a very small unit. If you are measuring something very large, like a building, you will use a larger unit.

Length is also the distance from one point of an object to the other point of the same object. Length is measured when we need to know how long an object is.

What Is Width?

Similar to length, width is the distance from one side of an object to the other. In geometry, width is also measured in units called “meters” or “feet”. Width is measured when we need to know how wide an object is. The width of an object is always the same as the length of a line that goes through the center of the object.

What Is a Scale Factor?

The scale factor of an object is the ratio between its length and width. If you have an object that is 2 meters long and 1 meter wide, then its scale factor is 2/1 or 2:1. If you have an object that is 3 meters long and 1 meter wide, then its scale factor is 3/1 or 3:1.

What Is the Area?

Area is the amount of space inside a closed shape. Area can be measured in units called “square meters” or “square feet”. The units used to measure area depend on what you are measuring.  In geometry, an area has units called “square units”. A square unit has sides that are all equal in length and angles that are all equal in size. This means that if we have an area with four sides (4 square units), we can create it by taking four squares with sides of 1 unit and angles of 1/4 unit.

Area is used to measure the amount of space inside a shape. Area is not used to measure the size of an object, like length and width are.

Length Vs. Width:

There are many differences between length and width. Some of them are:

1. The use in different situations

Length and width are two different terms that have been used in many situations. For example, when you talk about the length of a rectangle, it is the distance from one longer side to the other. When you talk about the width of a rectangle, it is the distance from one wider side to the other.

2. The application

Length is usually used to measure the distance between two points or two lines. Width is usually used to measure the distance between two points on a surface.

3. The term

The term length is commonly used in geometry, while the term width is commonly used in geometry and trigonometry.

4. The size

The length of a figure is related to the width of a figure. For example, the length of a rectangle is usually twice or more the width of the rectangle.

5. The formula

The formula for finding the length of a rectangle is L = w * h, where L is the length, w is the width, and h is the height. Using the same principle, the formula for finding the width of a rectangle is w = L / 2.

6. The related term

The term width is related to the term breadth. The term length is related to the term height.

7. The origin

The word length is derived from the word long. The word width is derived from the word broad.

8. The importance

The length and width are very important in geometry. However, when you need to measure the distance between two points, you usually need to use the length. When you need to measure the distance between two lines, you need to use the width.

9. The symbol

There are different symbols for length and width. For example, when you need to represent the length of a rectangle, you can use L or l. When you need to represent the width of a rectangle, you can use w or h.

10. The relation to other terms

There are many terms that are related to length and width. For example, the term perimeter is used to represent the length of a rectangle. The term area is used to represent the width of a rectangle.

11. What comes first

In some situations, the length comes first, while in other situations, the width comes first. For example, when you need to measure the distance between two high points, you need to use the length first. When you need to measure the size of a shirt, you usually need to use the width first.
