So, how exactly does the micro compare to other ones? Well, first of all, the microSD will be 15mm x 11mm x 1 mm thick. This compares to the 'standard size', which is 32 mm x 24 mm x 1.4 mm thick. For the 'mini size' it is 21.5 mm x 20 mm x 1.4 mm. Therefore, the micro size will be about a fingernail's size and additionally may be under one eighth / 1/8 of the standard-sized SD card. For your information, adapters exist which allow one to use microSD cards in a device which is required for a standard SD, miniSD, Memory Stick Duo and also in addition USB cards.
