The most space-saving sans serif

Even the name of the font implies its function: French for the infinitive “to save” is « économiser. » Now if that doesn’t sound good…

This font saves more space than any of its kind!
  
Slim proportions, but not “condensed”
  
Sparse ascenders and descenders
  
Distinct forms
  
Chamfered corners
  
Very close spacing between letters
How close to each other can the characters of a font get? Theoretically, as close as you want. But obviously, the words should still be legible. And as any designer knows, body clearance of characters also depends on other parameters such as point size and line spacing.

In practice, there are always situations in which as much information as possible has to be positioned in as little space as possible.

The Écono Sans is made for exactly this purpose.

The shapes of the upper and lower case letters are completely matter-of-fact, the way a modern font has got to be. The letters c, e, and s are wide open to their neighbors. An especially distinguished trait of this font is the design of the “triangular” characters v w y x k z and A V W Y Z K X M N. And the open form of A B R P is also not typical in a sans serif.
The distance between letters is kept tight and often the characters nearly touch, but only nearly.

Results of a comparison*:
With the normal ÉconoSans you gain approximately 20% more text in a line than with Tahoma, and even still more than 10% compared to Helvetica Neue, not to mention the old “normal” Helvetica…

* In order to truly compare, the fonts were measured up to the same visual size, i.e. ÉconoSans 12 pts, Avenir Next 12.5 pts, Bell Centennial 12.5 pts, Helvetica 11 pts, Tahoma 11 pts.

The font contains numerous OpenType features such as ligatures, alternate numerals for different purposes, stylistic alternates, and many more.
Among the ligatures, the double mm is especially unusual and is hardly familiar, but can contribute greatly to saving space without catching the reader’s eye.
Alternate styles of the letters a g u enable a more open overall impression in the typeface.

Last but not least, Écono Sans is a variable font that contains an entire font family from Thin to Black, from Condensed to Normal to Expanded, including the corresponding italics.
