T-shirt size
In several contexts, T-shirt sizes refers to the standardized clothing sizes used for t-shirts as a more general concept applicable to all sorts of dimensions, e.g. in agile software development as part of planning poker[1].
At its base, these are the sizes small (S), medium (M) and large (L). Non-medium sizes can be augmented by the prefix extra (X), generating additional sizes XS and XL. This can be repeated if needed. Multiple extra prefixes are abbreviated either as the respective number of the letter X, i.e. XXS and XXL etc., or as their count given as a digit before the letter, i.e. 2XS and 2XL etc.
Variants
Sometimes, extra small (XS) and extra large (XL) are replaced by other single-word designations like tiny (T) and huge (H), respectively, so they can be represented by a single unique letter. Likewise, instead of reduplicating the prefix extra there are sometimes alternative modifiers like super (S) and ultra (U), so every size can be represented by a maximum of two letters. To make all size abbreviations exactly two letters, e.g. in CSS class names of Bootstrap[2], the base sizes may be represented as SM, MD and LG instead. Rarely, e.g. in Korean/Japanese clothes, there is no prefix but the size designator itself is repeated, i.e. SS and LL.[3] CSS use the letter x as a prefix in named font sizes but does not abbreviate the base size, so it runs from xx-small through xx-large.[4]

In many scenarios, including clothing sizes themselves, there are more large than small sizes, e.g. 3XL, 4XL and 5XL but just XS, so the medium size is not really in the middle. Although t-shirt size may be used to categorically bin ranges on an interval scale, they can only be arranged on an ordinal scale themselves.
