Helvetica punches above its weight for a simple rounded sans-serif font.
Arial (originally Sonoran Sans Serif) was made popular by Microsoft through packaging with Windows, and is often seen as a ubiquitous equivalent to Helvetica.
‘Equivalent’ is rather a subjective word in this case and for some it’s easy to spot the differences between the fonts. Arial could be said to have ‘Helvetica envy’.
Meanwhile poor old ‘Times New Roman’ is now languishing into relative obscurity based more on the fact it’s an older style serif font. The ‘new’ is therefore something that people now gloss over (new in 1931).
These two designs are just a small celebration of how the world loves Helvetica.
