HC Deb 30 October 1957 vol 575 c63W
94. Mr. Janner

asked the Postmaster-General whether he will increase the regulation size of postcards to that of continental size in view of the increased cost of postage.

Mr. Marples

The maximum size of postcards accepted for the post in this country—5⅞" x 4⅛"—is the same as in continental countries. This size is recommended by the Universal Postal Union.
