Shoe size characteristics of a system of shoe sizing to be known as Mondopoint" and ISO 3355:1975 "Shoe sizes - System of length grading (for use in the Mondopoint system)". ISO 9407:1991, "Shoe sizes—Mondopoint system of sizing and marking", is the current version of the standard. The Mondopoint system is based on average foot length and foot width for which the shoe is suitable, measured in millimetres. The length of the foot is measured as horizontal distance between the perpendiculars in contact with the end of the most prominent toe and the most prominent part of the heel. The width of the
Sizing with the goal of allowing inks and paints to remain on the surface of the paper and to dry there, rather than be absorbed into the paper. This provides a more consistent, economical, and precise printing, painting, and writing surface. This is achieved by curbing the paper fibers' tendency to absorb liquids by capillary action. In addition, sizing affects abrasiveness, creasibility, finish, printability, smoothness, and surface bond strength and decreases surface porosity and fuzzing. There are three categories of papers with respect to sizing: "unsized" ("water-leaf"), "weak sized" ("slack sized"), and "strong sized" ("hard sized"). Waterleaf has low water resistance
