Receptive web design has arrive of age and brand new modes of reading through text have surfaced. As a result, accessible kind selection is more essential than ever. The variety of information regarding available type design, software and code strategy is quite staggering, however one thing is clear: legibility of content has become the main goal for almost each and every website.

Fontsmith worked with Mencap to analyze, test and design available typefaces for those along with disabilities. Here are some of our own findings.

Typeface style


Legibility is concerned along with questions like: Are you able to recognize this notice or word? Are you able to interpret and understand this word? Legibility is concerned with: Exactly how comfortable is the reading through experience? Accessible kind design is each legible and legible.

Serifs & Sans Serifs

Our research indicates sans-serif fonts are the the majority of accessible style, because the detailing within serif-ed letters is considered sophisticated by those with looking at disabilities. Sans web site have a simplified construction; they sit more close to our learned handwriting. Mono-linear sans varieties display clearly including a more robust trend at small cote sizes, even in the particular harshest rendering surroundings.


Picking a typeface with solid character recognition features aids legibility. People that have visual impairments can discover certain letters puzzling, therefore it is important these letter shapes are usually clearly defined. Frequent offenders are the ‘I’ (eye), ‘i’ (lower-eye), ‘l’ (el) and also ‘1′ (one). Any closed ‘C’ can easily look like an ‘’. Open counter styles aid reading. The particular combination of ‘r’ and also ‘n’ can study like an ‘m’. Very long ascendance and descender are important too. They will help to define exterior word shapes a persons vision can scan and also interpret swiftly.

Font size

A large x-height and moderate-to-wide amounts are most obtainable. A larger x-height usually infers a greater whitened space inside a page, which can aid meaning and clarity. Frequently, condensed and squeezed width styles are usually promoted as permitting a fluid plus more responsive layout, nonetheless it is important to realize that will by using a condensed size where space is bound (e. g. in mobile) you could also end up being reducing accessibility.


Hints describe their education by which pixels must be turned on or down to improve the quality of the letter at a particular pixel size. In spite of improvements in display screen resolution, font leaving clues is still an essential kind design process. The majority of foundries automate leaving clues and achieve excellent results, but maintain expectations in check: absolutely no amount of hinting can make a heavy weight look great at 12px.

Kind application


Generate a hierarchy by determining roles. A hierarchy allows the eye to break down info into a clear encounter. Use open, mid-range weights for subheads and body. Setup a test to evaluate throughout browser platforms — weight can change significantly from one environment to another. If desired, apply Type Rendering Blend to balance out look.


Size is essential. Be mindful that every font sits at a various scale on the type-body, and actual dimensions can vary hugely among fonts: 14px in a single font can be equal to 16px in another. The typical size for entire body ranges from 16px to 18px. Typically 14px-plus is considered the the majority of inclusive. Font dimension can also impact on making quality.

Evaluate, minimize or increase as needed. Scanning long collections of text will be testing for your sight. Research indicates the average online series length is around 70-80 characters. Limit collections to no more than of sixteen words.


Font loading methods

Slow connections and huge font files can result in slow text fill up times. A single WOFF file with a total European character established will size 36-50KB. The states regarding FOUT (flash regarding unstyled text) or perhaps FOIT (flash regarding invisible text) will need consideration. FOIT will be the predominant browser arrears and in aesthetic conditions FOIT is desired, but in accessibility conditions FOUT is certainly ideal.

Seeing some content material is better than no content material at all. Aim to display text in a fallback until all internet fonts load. This particular avoids any continuing juddering of several elements on the web page. Implement with Internet Font Loader and place a cookie, because minimises FOUT additional into the site.

Fallback Typeface

Mobile fonts fallback match ups table illustrates the issue. When selecting a fallback, shoot for similar weight load and proportions. Modify fallback metrics to fit your chosen font dimension. Inform your choice decision by overlaying an accessible on the fallback as well as judge.


Enable kerning and improve making quality. This establishing also enables rapport, which you can disable if required by setting class name font-feature-settings: “serf” 0;
