By the time you receive the diagnosis for the condition of hydrocephalus, it is likely that you or your child have already been through a gamut of tests. This first of a three-part series describes the process of being diagnosed with hydrocephalus.
The ISO 216 standard defines A5 size to be 148mm Ã 210mm, which is also exactly half the size of an A4. Usually A5 sized paper will be used for booklet printing, flyers, leaflets, advertisements, or if on heavier stock, it can be scored and folded to make A6 sized greeting cards. In the ISO paper size system, the height-to-width ratio of all pages is the square root of two. In other words, the width and the height of a page relate to each other like the side and the diagonal of a square. This aspect ratio is especially convenient for a paper size.
A4 is part of the ISO 216-series of related paper sizes known more commonly as the A-series. This series starts with the large A0 sheet and a quick look at this large sheet of paper shows why these various sheets are the sizes they are. A0 sheets of paper are 841mm by 1189mm.
