Yes, A5 paper is half A4 paper. The ISO standardization organization stipulates the size of A series paper, and the width of A5 is equal to half of A4 and the length is slightly shorter than half of A4, so A5 paper is indeed half A4 paper, which is very convenient when printing and organizing documents.
Is the A5 sheet half an A4 sheet?
Clear answer: Yes
Detailed explanation:
The International Organization for Standardization (ISO) standardizes paper sizes It is the A series, of which A5 and A4 are commonly used sizes. A-series papers have a fixed aspect ratio of √2, or approximately 1:1.41.
- A4 paper: Dimensions are 210 × 297 mm, area 6237 mm².
- A5 paper: Dimensions are 148 × 210 mm, area 3150 mm².
Through calculation, we can find that the width of A5 paper is equal to half of the width of A4 paper, and the length is slightly shorter than half of the length of A4 paper (148 mm
