Two A3 pages next to each other in a spread equals the A2 paper size. This way a range of paper sizes is created from A0 (which has a surface of

**one square meter**) to A10. The height/width ratio remains constant for all sizes:**1:1.41**or the square root of 2.Keeping this in view, what is bigger a3 or a4?

A1, A2,

**A3**,**A4**) measurement is determined by halving the dimensions of the preceding one. For example the most commonly used paper size is**A4**(297mm x 210mm) and the next paper size is A5 (210mm x 148.5mm) which is equal to half of the**A4**dimensions.**A3**(297mm x 420mm)What is double of a3?

**A3**297mm x 420mm (

**double**the size of an A4) A2 420mm x 594mm (

**double**the size of an

**A3**) A1 594mm x 840mm (

**double**the size of an A2) A0 840mm x 1,188mm (

**double**the size of an A1)
