Paper size

Paper size is the size of the paper that we use for writing, drawing or printing. Think of it like a big rectangular shape that varies in size. The most common paper size is called A4, and that's what you usually use for homework or printing out pictures.

To help you understand better, let's say you are a kid who loves to draw on paper. Your mom goes to the store and buys you a new pack of paper, but this time she asks you what size you want. You could ask for a smaller size that's easy to carry around or a bigger size for drawing bigger pictures.

If you choose a bigger size, it means you'll be able to draw more on one page, but it might be harder to carry around. But if you choose a smaller size, you might be able to fit it in your backpack easily but you won't be able to draw bigger pictures.

The 'A' is used to describe the size of the paper in a way that is easy to understand. A4 is a standard size that is 210mm wide and 297mm tall.

So, the next time you need to use paper, you can think about what size you need based on what you want to do with it. Remember, paper comes in different sizes and you can choose the one that's best for you!
