New on CTAN: typoaid
A new package that measures alphabet lengths, em widths and ex heights, and that may be useful for making typesetting decisions. Future versions will be able to suggest measure and textblock height and to provide diagnostic tools.
The package’s Catalogue entry can be viewed at https://ctan.org/pkg/typoaid The package’s files themselves can be inspected at http://mirror.ctan.org/macros/latex/contrib/typoaid/

typoaid – Macros for font diagnostics
This package provides macros for measuring alphabet lengths (i.e. the length occupied by the characters “abcd…xyz”), em-widths and ex-heights, which may help in making typesetting decisions.
The package is compatible with pdfLaTeX, LuaLaTeX, and XeLaTeX, and will accept font family switches defined via the fontspec package.
The plan is that future versions shall be able to provide even more diagnostic tools, and some LuaTeX-specific special commands, too.
