Verdana v. Futura

Verdana and Futura are both sans serif typefaces. Verdana's x-height is significantly taller than futura's. The rounded parts of verdana tend to be more subtle where futura's are all based on circles. Also the peaks of a few of futura's capital letters are sharp where as verdana's are not. The dots of futura's i's are round while verdana's are square.
