Weight per sheet

Paper weight is printed as g/m² — grams for one square metre. An A4 is a sixteenth of an A0, so 0.0625 m²; at 80 g that is 5 grams. If a letter must stay under 25 grams, 80 g paper gives you five sheets.

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.
