About this tool
This A4 paper size chart (paper size guide for A series, B series, mm, cm, inch and pixels) shows the width and height of every standard sheet from A0 to A10 and from B0 to B10.
A4 is 210 x 297 mm, which is 21 x 29.7 cm, or 8.27 x 11.69 inches. How many pixels is A4? It depends on the dpi: about 595 x 842 px at 72 dpi for screens and 2480 x 3508 px at 300 dpi for sharp printing.
The pixel figure is the size in inches times the dpi, rounded. What is the difference between ISO B and JIS B?
JIS B5 is 182 x 257 mm and ISO B5 is 176 x 250 mm, and in Korea B4 and B5 usually mean the JIS sizes, so the chart has both. Each step down halves the sheet, so two A5 pages make one A4.
Choose a series, pick a size and then change the unit to read the whole table in mm, cm, inches or pixels.
These are standard values; printers, margins and cutting can differ slightly, so check your printer settings before a big job. For image sizes in other units, the unit converter and the length converter can help.
