Size is the practical decision and it is usually made too small. A note that only fits three words gets abbreviated into something the writer cannot decode a week later, where a larger pad carries a real instruction. Keep one small format for page flags and one larger for messages. Adhesive is low tack, so nothing is held by these. See sticky notes, writing pads and desk accessories.
