Definition
What is it?
The width of a shape is how broad or wide it is from one side to the other. It's one of the measurements we use to describe how big a shape is, usually the shorter side when compared to its length.
Simple Example
Quick Example
Imagine your school desk. The measurement from the left edge to the right edge, across the front where you sit, is its width. It tells you how much space it takes up from side to side.
Worked Example
Step-by-Step
Let's find the width of a rectangular cricket pitch.
Step 1: Identify the shape. It's a rectangle.
---Step 2: Remember that a rectangle has a length (the longer side) and a width (the shorter side).
---Step 3: Measure the longer side of the pitch. Let's say it's 20 meters. This is the length.
---Step 4: Measure the shorter side of the pitch. Let's say it's 10 meters.
---Step 5: The shorter side is the width.
---Answer: The width of the cricket pitch is 10 meters.
Why It Matters
Understanding width is super important for designing buildings, fitting furniture, or even planning roads. Architects use it to draw blueprints, engineers use it to build bridges, and even app designers consider screen width for their layouts. It's a basic building block for many exciting careers!
Common Mistakes
MISTAKE: Confusing width with length, especially in shapes that are nearly square. | CORRECTION: Length is typically the longer dimension, and width is the shorter dimension. If the shape is a perfect square, length and width are equal.
MISTAKE: Not specifying the units when stating the width. | CORRECTION: Always mention the unit of measurement (e.g., centimeters, meters, kilometers) after the number to make it clear.
MISTAKE: Measuring the diagonal instead of the straight side-to-side distance. | CORRECTION: Width is a straight line measurement from one edge to the opposite edge, not across a corner.
Practice Questions

QUESTION: A mobile phone screen is 7 cm wide. If you place two phones side-by-side, what would be their combined width? | ANSWER: 14 cm
QUESTION: A rectangular photo frame is 15 cm long and 10 cm wide. Which measurement represents its width? | ANSWER: 10 cm
QUESTION: Your school playground is 50 meters long. If its area is 2000 square meters, what is the width of the playground? (Hint: Area = Length x Width) | ANSWER: 40 meters
MCQ
Quick Quiz
What does the width of a rectangular table tell you?
How tall the table is
How long the table is from end to end
How broad the table is from side to side
How heavy the table is
The Correct Answer Is:
C
Width describes how broad or wide something is from side to side. Length describes how long it is, and height describes how tall it is.
Real World Connection
In the Real World
When you buy a new TV, you often check its width to see if it will fit on your TV stand or in your wall unit. Similarly, when a tailor stitches a kurta, they measure the width of the fabric to ensure it's enough for the body and sleeves. Even when designing a new road, engineers consider the width to decide how many lanes it can have.
Key Vocabulary
Key Terms
WIDTH: The measurement of how broad or wide a shape is from side to side. | LENGTH: The measurement of how long a shape is, usually the longer side. | DIMENSION: A measurement like length, width, or height. | MEASUREMENT: The size, amount, or extent of something.

What to Learn Next
Now that you understand width, you can move on to learning about 'Length' and 'Height'. These concepts, along with width, are called dimensions and help us describe all sorts of 2D and 3D shapes around us!
