Hi, does anyone know of any free alternatives to Co by Dalton Maag? I would really appreciate it!

Thanks

On a scale of 1 to 100 how close should it match? Say 1 and any sans will do. Say 50 and any sans will do. Say 70 and any sans will do. See, you have to be more precice about what you are looking at. Which character is fundamental?

What you are asking now is something like "have something similar to a tree".

If you just want a free sans with a lot of different styles/ weights, try Encore Sans by Pablo Impallari and Andreas Torresi: http://www.impallari.com/testing/encode/index.php. It has a total of 45 fonts, it's brand new, (available since the end of March, 2014), and it's Donationware. Pablo made the Lobster font, which has been recognized 368 times in the Font Identification forum.

It needs to have the same kind of feel. It needs to be curvy and come in different weights.

Already got it thanks.

It's mainly the lowercase a and b that need to be similar.

Depends on your definition of similar. Here are three that are here on dafont that might fall within your - not mine - definition for similar for the a and b. Carme, Sansation and Ubuntu Mono. I don't know if they fit your definition of free.

Similar = almost the same. Not my definition - it's the correct definition.
Stop talking about different definitions - your attempts to humorous by saying things such as
are pathetic. I told you which character was fundamental when you asked, and you are still being arsey about it.

If even the Ubuntu is no good for you, buy the Co.
