WhatFontIs vs WhatTheFont Font Identification Services
In order to test, I typed out some text in a known font installed on my system and filled them in red. I exported each of the samples as a fairly mediocre quality JPG that is only 200 pixels wide. I wanted something with less than ideal quality as that is a better test of the real world examples you need to identify. I've included each sample in this post so you can see them and use them in your own tests if you like.
Our first font, shown above, came from one of those mega-collections sold in the mid-90s with a bunch of so-so quality fonts. It's name is Pretoria and both services correctly identified it as the top choice. While neither service correctly identified the source collection of this font, they did get the name right and provided a link to a source for the font. Note that "a source" does not always mean a free source, especially when we are dealing with commercial fonts.
My second sample was the font I featured in yesterday's blog, Babes in Toyland NF. Again, both services correctly identified the font. One difference I did note between the two is that WhatTheFont tries to fill in each of the letters used (not always correctly) where you must type them into WhatFontIs. In the second example, WhatTheFont incorrectly had capital letters in each box when only the first letter is truly a capital letter.
According to the folks at WhatFontIs, their database of fonts is much larger and includes more free fonts. I'm sure if I tested many more examples I could find a situation where one or the other service performed better on that example. The best advice I can give you is that you now have two good services you can use for font identification. Should one not work on a specific example, you can try the other service. My tests didn't show either service to clearly be the best.
