We are currently revising our website, which uses Verdana for most of the body copy and navigation etc. My boss thinks that using arial instead is a great idea, and despite my protestations that Verdana was designed for the web and screen and arial is a dirty Microsoft knock-off, designed only to save money, he needs some convincing. Put on the spot I mumbled something about Verdana being more accessible and legible on screen and more efficient, but as I'm not a typographer I thought I'd ask for help from the real experts.
Can someone help me out with some solid reasons that might convince a typographically illiterate person that the choice of font for the web IS important, and that Verdana is preferable to Arial in this case?
Of course if people agree with him I'll shut my mouth and never give an opinion on typographical matters again.
cheers.
