Redondo is available in 2 sizes – 1.5 & 3. That refers to the average height in mm. I have all of the numbers in each size as well. There is a reason for the huge investment in custom tools… it’s extremely readable, it pairs well with other fonts and itself, and it is unisex. It is considered a unicase font, though to me it’s really an all – caps font. It is very even as well.
Both sizes are represented in these photos. You may click on each photo to see it enlarged.
