PT Serif is a transitional serif face with humanistic terminals designed for use together with "PT Sans"/typeface/ptsans and harmonized with PT Sans on metrics, proportions, weights and design. PT Serif consists of six styles: regular and bold weights with corresponding italics form a standard font family for basic text setting; two caption styles (regular and italic) are for texts of small point sizes.
