Lato是一款无衬线字体家族，由华沙设计师Łukasz Dziedzic于2010年夏季设计完成（"Lato"在波兰语中意为"夏季"）。2010年12月，该字体家族通过其铸造厂tyPoland在谷歌的支持下，以开源Open Font License协议正式发布。

2013至2014年间，该字体家族大幅扩展，每个样式涵盖超过3000个字形。Lato 现支持100多种拉丁语系语言、50多种西里尔语系语言，并兼容希腊语和国际音标标注。在此过程中，字体的度量标准和字间距调整均经过修订，还新增了四种字重。

在Łukasz从事字体设计的近十年间，他的多数创作都源于需要解决的具体设计任务，Lato亦不例外。最初，这个字体家族是为某大型客户量身定制的企业字体，但客户最终选择了不同的风格方向，因此该字体得以向公众发布。

在打造Lato的过程中，Łukasz试图谨慎平衡若干可能相互冲突的设计目标。他力求创造一种在正文排版时呈现"透明"特质的字体，同时在放大显示时能展现独特的个性特征。通过采用经典比例（尤其体现在大写字母中），他赋予了字形熟悉的协调感与优雅气质。与此同时，他塑造出流畅的无衬线外观，清晰彰显Lato诞生于2010年的时代特征，尽管并未盲目追随任何流行趋势。

字母的半圆角细节为Lato赋予了温暖感，而坚固的结构则奠定了稳重严肃的基调。"刚柔并济，庄重而不失亲和，同时蕴含着夏日氛围，"Łukasz这样阐释道。

Lato包含九种字重（及对应斜体），其中包括优雅的Hairline极致细体。当然，Hairline风格仅适用于超大字号场景。目前Lato家族已支持100多种拉丁语系语言、50多种西里尔语系语言，并兼容希腊语与国际音标标注！

Lato is a sanserif typeface family designed in the Summer 2010 by Warsaw-based designer Łukasz Dziedzic ("Lato" means "Summer" in Polish). In December 2010 the Lato family was published under the open-source Open Font License by his foundry tyPoland, with support from Google.

In 2013-2014, the family was greatly extended to cover 3000+ glyphs per style. The Lato 2.010 family now supports 100+ Latin-based languages, 50+ Cyrillic- based languages as well as Greek and IPA phonetics. In the process, the metrics and kerning of the family have been revised and four additional weights were created.

In the last ten or so years, during which Łukasz has been designing type, most of his projects were rooted in a particular design task that he needed to solve. With Lato, it was no different. Originally, the family was conceived as a set of corporate fonts for a large client — who in the end decided to go in different stylistic direction, so the family became available for a public release.

When working on Lato, Łukasz tried to carefully balance some potentially conflicting priorities. He wanted to create a typeface that would seem quite "transparent" when used in body text but would display some original traits when used in larger sizes. He used classical proportions (particularly visible in the uppercase) to give the letterforms familiar harmony and elegance. At the same time, he created a sleek sanserif look, which makes evident the fact that Lato was designed in 2010 — even though it does not follow any current trend.

The semi-rounded details of the letters give Lato a feeling of warmth, while the strong structure provides stability and seriousness. "Male and female, serious but friendly. With the feeling of the Summer," says Łukasz.

Lato consists of nine weights (plus corresponding italics), including a beautiful Hairline style. The Hairline should, of course, be used only in very large sizes. The Lato family now supports 100+ Latin-based languages, 50+ Cyrillic-based languages as well as Greek and IPA phonetics!
