The CSSWG already renamed those terms (you're reading an outdated TR
version).  We'll update the specs in the next few months.

The current terms can be found in the Editor's Draft: inline-size
(size in the inline dimension; horizontal in English) and block-size
(perpendicular to that).

SVG chose the wrong term anyway - "measure" is literally "the length
of a line of text"  ^_^
