What is A5 in inches?

A5 is 148 × 210 millimeters, which equals 5.83 × 8.27 inches. It keeps the 1:sqrt(2) aspect ratio and has half the area of A4.

How do I print an A4 document as an A5 booklet?

Use booklet mode or scale to roughly 71 percent (sqrt(2)/2), enable duplex short-edge binding, and add 7–10 mm inner gutter so the spine does not hide text.

How much margin or bleed should I keep for A5?

Leave at least 5 mm safe margin on all sides; for print-ready files add 3 mm bleed plus crop marks to avoid trimming logos or text.
