Instead, the label should show the range of body dimensions from half the step size below to half the step size above the design size (e.g., "height: 172–180 cm."). For heights, for example, the standard recommends generally to use the following design dimensions, with a step size of 8 cm:
There is no mandatory clothing size or labeling standard in the US, though a series of voluntary standards have been in place since the 1930s. The US government, however, did attempt to establish a system for women's clothing in 1958 when the National Bureau of Standards published Body Measurements for the Sizing of Women's Patterns and Apparel ...
Although more common in women's apparel, vanity sizing occurs in men's clothing as well. For example, men's pants are traditionally marked with two numbers, "waist" (waist circumference) and "inseam" (distance from the crotch to the hem of the pant). While the nominal inseam is fairly accurate, the nominal waist may be quite a bit smaller than ...
There are multiple size types, designed to fit somewhat different body shapes. Variations include the height of the person's torso (known as back length), whether the bust, waist, and hips are straighter (characteristic of teenagers) or curvier (like many adult women), and whether the bust is higher or lower (characteristic of younger and older women, respectively).
In fashion and clothing, a petite size is a standard clothing size designed specifically for women 163 cm (5 ft 4 in) and under. [1] [2] [3] This categorization is not solely based on a woman's height, but also takes into account the proportions of her body. Petite sizes cater to body shapes that typically have shorter limb lengths, narrower ...
A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by a dash or sometimes the multiplication sign, × (e.g. M8-1.25 or M8×1.25).
Whitworth's new standard specified a 55° thread angle and a thread depth of 0.640327p and a radius of 0.137329p, where p is the pitch. The thread pitch increases with diameter in steps specified on a chart. The Whitworth thread system was later to be adopted as a British Standard to become British Standard Whitworth (BSW).
The number series of machine screws has been extended downward to include #00-90 (0.047 in = 0.060 in − 0.013 in) and #000-120 (0.034 in = 0.060 in − 2 × 0.013 in) screws; [3] however, the main standard for screws smaller than #0 is ANSI/ASME standard B1.10 Unified Miniature Screw Threads. This defines a series of metric screws named after ...
