§ 57. Mr. Parker
asked the Postmaster-General whether he will standardise the size of envelopes by metric measurements.
§ Mr. Benn
I quoted the sizes in inches in order to help users of envelopes and the trade. However the new international76W standards were agreed in metric terms as follows: the limits of envelop width as not less than 90 millimetres or more than 120 millimeters, and of length as not less than 140 millimetres or more than 235 millimetres.
