B6 as an envelope
A B6 envelope at 125 × 176 mm goes as a Letter with Royal Mail, which allows up to 240 × 165 mm, 5 mm and 100 g. In Germany it is just about a Standardbrief: Deutsche Post allows up to 235 × 125 mm, and B6 uses the full height to the last millimetre. That makes B6 a good choice when a card is too big or too thick for C6 but the postage should stay low. All limits are on German letter sizes.
ISO B6 and JIS B6
Many notebooks labelled B6 come from Japan and follow JIS. JIS B6 measures 128 × 182 mm, 3 mm wider and 6 mm taller than ISO B6. Buy covers and refills by the millimetre measurement, not by the name. More on the differences under international paper sizes.
