Figure space
Typographical space as wide as a numeral From Wikipedia, the free encyclopedia
A figure space or numeric space[1] is a typographic unit equal to the size of a single numerical digit. Its size can fluctuate somewhat depending on which font is being used. This is the preferred space to use in numbers. It has the same width as a digit and keeps the number together for the purpose of line breaking.[2]
