Comma Base is a sans typeface for it has no serifs. No wait, it is a typical serif typeface because it has a high contrast. Strictly speaking, Comma Base is a missing link between serif and sans, offering the best of both worlds. Comma Base supports several OpenType features for advanced typographic control. It consists of 16 styles, 8 weights from Hairline to Ultra, in both roman and italic. Comma Base is a uniwidth font. This means changing a text from normal to bold doesn’t effect the set width, a professional feature that is highly appreciated by graphic designers.
