I want to share with you a tool I developed to help us designers choosing fonts for our css stacks that are similar in aspect values and alphabet widths for a given font size.
The tool, FontInstead, can gather metrics of the fonts you have installed on your computer and give you statistics about gathered font metrics.
Please, visit http://adrianodigiovanni.com/fontinstead to let FontInstead analyze your fonts and grow the list.
FontInstead is a beta project. I would appreciate comments, suggestions, bug reports.
Thanks in advance,
