Understands the Paper sizes (Printer Paper Size)

People often ask questions like, “Which is bigger: A3 or A4?”, “What are the dimensions of A3, A4, and A5 paper sizes?”, “How large is A3-sized paper?”, “Which is larger: A1 or A2?”, and “Is A1 bigger than A3?”. Let’s clarify which paper sizes are larger and which are smaller.

  • A0: The base size, which has an area of 1 square meter. Dimensions are 841 x 1189 mm.
  • A1: If you cut an A0 in half, you get two A1 sheets. Dimensions are 594 x 841 mm.
  • A2: Cut an A1 in half, and you get an A2. Dimensions are 420 x 594 mm.
  • A3: Halve an A2 to get A3. Dimensions are 297 x 420 mm.
  • A4: When you cut an A3 in half, you get the well-known A4 size, which is commonly used for letters, documents, and standard printing. Dimensions are 210 x 297 mm.
  • A5: Cut an A4 in half to get A5. Dimensions are 148 x 210 mm.

… and the sequence continues down to A10 and smaller, though sizes below A5 are less commonly used for standard print tasks.

So, following this sequence:

  • A4 is bigger than A5.
  • A5 is bigger than A6.
  • A6 is bigger than A7. … and so on.

To reiterate, the higher the number after the ‘A’, the smaller the paper size.
