How to read this

Dimensions are in millimetres. Leftover fractions are dropped when folding, exactly as the standard says.
Pixel counts are rounded. Printers usually ask for 300 dpi.
The weight is the paper alone. Add the envelope and the ink separately.
Letter and Legal are defined in inches, so folding them does not preserve the √2 ratio.
