What is it?

Width is the measurement of how broad or wide something is from one side to the other. It tells us the extent of an object or a space across its shorter dimension, usually perpendicular to its length. Think of it as how much 'space' something takes up side-to-side.

Simple Example

Quick Example

Imagine your school desk. The measurement from the front edge to the back edge is its depth or length. The measurement from one side of the desk to the other side, where you keep your books, is its width. A wider desk gives you more space to spread out your stationery.

Worked Example

Step-by-Step

Let's say you want to know the width of your bedroom door.
---Step 1: Get a measuring tape. Ask an elder for help if needed.
---Step 2: Hold one end of the measuring tape against the inner edge of the door frame on one side.
---Step 3: Stretch the tape straight across to the inner edge of the door frame on the opposite side.
---Step 4: Read the number on the tape where it meets the second edge. Make sure the tape is flat and not bent.
---Step 5: If the tape shows 90 centimeters, then the width of your door is 90 centimeters. This tells you how wide a new cupboard can be if you want to take it through the door.

Why It Matters

Understanding width is crucial in many fields, from designing buildings to fitting furniture into a room. Architects use it to plan room sizes, and engineers use it to design roads and bridges. Even fashion designers consider width when creating clothes to ensure they fit well, making it a fundamental concept in design and construction.

Common Mistakes

MISTAKE: Confusing width with length or height. | CORRECTION: Width is usually the shorter horizontal dimension, while length is the longer horizontal dimension, and height is the vertical dimension.

MISTAKE: Measuring width diagonally or inaccurately. | CORRECTION: Always measure width in a straight line, perpendicular to the length, from one edge to the opposite edge to get an accurate reading.

MISTAKE: Not specifying the units when stating width. | CORRECTION: Always mention the unit (like centimeters, meters, inches) after the number to make the measurement clear and useful.

Practice Questions

Try It Yourself

QUESTION: A mobile phone screen is 6 cm wide. If you put two such phones side-by-side, what would be their combined width? | ANSWER: 12 cm

QUESTION: Your lunchbox is 15 cm long and 10 cm wide. Your school bag has a pocket that is 12 cm wide. Will your lunchbox fit into the pocket comfortably along its width? | ANSWER: No, because the lunchbox's width (10 cm) is less than the pocket's width (12 cm), so it will fit. (Correction: The question asks if it will fit *comfortably along its width*. Since 10cm < 12cm, it will fit. The previous answer 'No' was incorrect.)

QUESTION: A standard cricket pitch is 3.05 meters wide. If a boundary rope is placed 10 meters away from one side of the pitch, what is the total width from the other side of the pitch to the boundary rope? | ANSWER: Total width = Width of pitch + Distance to boundary rope = 3.05 meters + 10 meters = 13.05 meters

MCQ

Quick Quiz

Which of these objects would you typically measure its width?

The height of a building

The distance from Delhi to Mumbai

The size of a TV screen from left to right

The time it takes to cook rice

The Correct Answer Is:

Width refers to the side-to-side measurement. The size of a TV screen from left to right is its width. Height is vertical, distance is length, and time is a different concept.

Real World Connection

In the Real World

When you buy a new refrigerator for your kitchen, you must measure the width of the space available in your kitchen and the width of the refrigerator itself. If the fridge is wider than the space, it won't fit! Similarly, when designing a new road, engineers decide its width based on how many lanes of traffic it needs to carry.
