Using WPF, what is the most efficient way to measure a large number of short strings? Specifically, I’d like to determine the display height of each string, given uniform formatting (same font, size, weight, etc.) and the maximum width the string may occupy?
The most low-level technique (and therefore giving the most scope for creative optimisations) is to use GlyphRuns.
It’s not very well documented but I wrote up a little example here:

The example works out the length of the string as a necessary step before rendering it.
