The Franklyn team created a prototype of the thin weight, which I refined as I added two heavier weights. Betafont is full of optical adjustments. These details keep the heavier styles legible at small sizes and also preserve the circular appearance of many letters.
Betafont Type Family
Betafont references typewriter letters and monospaced fonts for programming, but the typeface itself is not monospaced. This allows it to read more like a traditional text face even though it doesn’t look like one.
