Standard 7” HD IPS screen video brochure VGC-070 is A5 (210 x 148) because it is easy for people to carry and store. Funtek Video Brochure has a similar size to a Kindle or iPad so will fit in a handbag or large coat pocket in a similar way. A5, which is roughly the equivalent of two standard postcards placed together, is the most convenient size for a portable marketing device.
