Measure is the printer's term for the line length (in effect).

However, I agree that it could usefully be clarified. But, "particularly 
when the containing content box is small in the inline text progression 
dimension so that each stacked line box contains few or no word-break 
opportunities" is back in the land of CSS jargon but not much clearer. A 
glossary definition of measure (which doesn't correspond to any single 
CSS property directly) might be more helpful. For example,

measure - the space available for lines of text; this gives the maximum 
possible line-length. It is generally equal to the dimension of the CSS 
content box in the inline progression direction but may also be affected 
by floats or other intrusions in some circumstances.

might help? (I think we actually agreed a simpler replacement for inline 
progression direction, which would obviously be used instead if so).
