The Helvetica family is available with fonts in different weights. Each font with a different weight has a different characteristic. This is the same with the redrawn version known as the Helvetica Neue family. It is important for all designers and regular Helvetica font users to understand the true weights of all the fonts. This information is important for you to understand which font suits your screen and printing requirements.
For instance, Helvetica Medium was delivered by early personal computers when the font was named as Bold. This was because the true bold resolution was not compatible with screens in the 80′s. Further to that, the Helvetica Neue Thin was introduced, which falls between the features and styling of Helvetica Medium and Helvetica Regular. The characteristics are quite similar, but the width and weight are slightly compressed and reduced between the two aforementioned fonts.
