===Optical sizing===
{{main|Font#Optical size}}
During the metal type era, all type was cut in metal and could only be printed at a specific size. It was a natural process to vary a design at different sizes, making it chunkier and clearer to read at smaller sizes.<ref name="How To Choose The Right Face For A Beautiful Body">{{cite web|last1=Reynolds|first1=Dan|title=How To Choose The Right Face For A Beautiful Body|url=http://www.smashingmagazine.com/2012/05/how-to-choose-the-right-face-for-a-beautiful-body/|website=Smashing|date=21 May 2012|access-date=13 September 2015}}</ref><ref name=MicroPlus>{{cite web|last1=Frere-Jones|first1=Tobias|title=MicroPlus|url=https://frerejones.com/blog/introducing-microplus|publisher=Frere-Jones Type|access-date=1 December 2015}}</ref> Many digital typefaces are offered with a range of fonts (or a variable font axis) for different sizes, especially designs sold for professional design use. The art of designing fonts for a specific size is known as [[Font#Optical size|optical sizing]]. Others will be offered in only one style, but optimised for a specific size. Optical sizes are particularly common for serif fonts, since the fine detail of serif fonts can need to be bulked up for smaller sizes.<ref>{{cite web |last1=Ahrens  |last2=Mugikura |title=Size-specific Adjustments to Type Designs |url=http://justanotherfoundry.com/size-specific-adjustments-to-type-designs |publisher=Just Another Foundry|access-date=21 November 2014}}</ref><ref>{{cite web|last1=Coles|first1=Stephen|title=Book Review: Size-specific Adjustments to Type Designs|url=http://typographica.org/typography-books/size-specific-adjustments-to-type-designs/|website=Typographica|access-date=21 November 2014}}</ref><ref>{{cite web|last1=Kupferschmid|first1=Indra|title=Multi-axes type families|url=http://kupferschrift.de/cms/2012/05/multi-axes-families/|website=kupferschrift|date=13 May 2012 |access-date=8 December 2014}}</ref>

Typefaces may also be designed differently considering the type of paper on which they will be printed. Designs to be printed on absorbent [[newsprint]] paper will be more slender as the ink will naturally spread out as it absorbs into the paper, and may feature [[ink trap]]s: areas left blank into which the ink will soak as it dries. These corrections will not be needed for printing on high-gloss cardboard or display on-screen. Fonts designed for low-resolution displays, meanwhile, may avoid pure circles, fine lines and details a screen cannot render.<ref>{{cite web|last1=Reynolds |last2= Koeberlin|title=Socialist TV Typeface Videtur Finally Freed|date=5 April 2013 |url=http://ilovetypography.com/2013/04/06/socialist-tv-typeface-videtur-finally-freed/ |publisher=FontFont |access-date=24 May 2015}}</ref>
