I'm failing to find a replacement for Univers Condensed to use on the Web. I'm using Typekit (portfolio), and right now using LFT Etica Web which is much wider than Univers. I tried Googleing but no luck, so I decided to sign up and ask the pros.
I would consider the google-font "Oswald" It comes only in 3 weights and has no italic or oblique version, but reminds me of the Univers Condensed type. Try changing Oswald 1pt less than Univers, regular -> light and bold -> regular.. Last, change tracking to +50..
That should do the job.. :-)..
Roboto Condensed is a close alternative, and available on Google web fonts
The great thing about Univers is that it comes in so many weights and widths. It's a real powerhouse of a typeface.
Very few typefaces come with the range of fonts that Univers does. So there's really no universal 'alternative'.
Now, if you are only using one particular weight of Univers, we could maybe find a font with similar metrics.
All that said, you don't need an alternative. You can license Univers as a web font:
It's hard to find good-quality Condensed sans serif fonts as free/libre/Open Source software.
U001CON by URW
Font foundry URW created a 'clone' of the Univers and Univers Condensed design and donated them to the Ghostscript / GhostPDL project as open-source software, under the Aladdin Free Public License.
If you don't need a look-alike recreation of Univers Condensed, you might consider these alternatives:
Open Sans Condensed
Open Sans, by Steve Matteson. It's considered more "humanist" than the geometrical form of Univers, but may serve a similar purpose for you. As of 2021, there is now a Condensed Regular (on Github, but not on Google Fonts yet).
Fira Sans Compressed
A very well designed sans serif with about the same width as Univers Condensed, but much more personality. By Erik Spiekermann, Ralph du Carrois, Anja Meiners, Botio Nikoltchev of Carrois Type Design and Patryk Adamczyk of Mozilla.org. Released under the SIL Open Font License.
By Omnibus-Type from Argentina, this font turns up the "square"-ness of Univers Condensed up to 11. It's especially interesting because there are many widths offered, including Semicondensed, Condensed and Extra-Condensed --- similar to the Univers superfamily.
I've been looking for the same answer without pay a cent, so I found this font in typekit trial: https://typekit.com/fonts/nimbus-sans-condensed
I hope you like it.
