Best And Worst Fonts For Dyslexia

Reading and learning compromises in people may be brought about due to multiple reasons. Such hitches need to be managed with proven strategies. Before that one may need to comprehend what factors lead to such compromises. On the whole, it may be visual as well as brain processing concerns. While we know yellow overlays can assist them to read better, can a fitting font add up to further mastery? Evidently, one may often prefer a smoothly comprehensible font, as they go serene on their eyes. For special needs individuals, the font of the text they infer thereby may turn preeminent. 

Consequently, What attributes make a befitting font for such people? What fonts are best and worst for them? Here, in this post, we will look into relevant insights so that you can choose books with the right font for your little ones. 

Impediments that dyslexics hit on in reading 

According to Arnold Wilkins[1], colored overlays can reduce the visual strain. He observed that almost five percent of students read about 25% better with their befitting color of the overlay. Further, considering a few challenges in reading text, there can be broadly three effects that an individual comes across: Washout, river, or Swirl effect as suggested by read regular makes reading taxing in most cases. 

  • Washout Effect: Here, the individual is aware of the size, font, and layout of the text. But, the color seems to be light and washed out, especially in the center of the letters. All this drastically reduces the contrast with the background, making it strenuous to distinguish letters to read.
  • River Effect: Some individuals may notice the text with the right contrast. However, they may feel it arduous to check out the spaces between words. This causes alignment issues, making them combine two words into one or break word into two. For instance, “or title” can be processed as “ortitle,” or “justified” may be processed as “justi fied.”
  • Swirl Effect: Individuals may lack focus while reading. Consequently, when they try looking at a piece of text, the surrounding letter seems to be distorted while the letter in focus is seen appropriately. This effect reduces the speed of reading since the person may take time to infer each word.

Befitting text fonts- Comprehending obligatory attributes

To make the text comprehensible with ease by anyone, a few tips can be ensured. These not only improve the contrast but also ameliorate the text acceptable for all ages too. 

  • Letter Spacing: Spacing between letters can be a crucial factor in making the text easily readable.  Even for people with learning compromises, having a word space of at least 3.5 times a letter width is often befitting.
  • Less Crowded: Overcrowding of text can invite ambiguity and inaccuracy. Ensuring enough line and word space can make the text clean and readable. Smaller paragraphs can also ameliorate the reading experience.
  • Simple Letters: Opting for easy fonts like Arial gives out a decent attire and makes reading facile and interesting.
  • Caps notable: Some letters like ‘i’ and ‘j’ have caps, which are often skipped by special needs readers. To address the same, fonts that ensure large or notable caps work better.
  • Thick words: Letters being thick can evidently improve the contrast and are easy on the eyes. Setting letters in bold can aid in many cases. Consequently, italic and underlines should be preferably avoided. 

Fonts for dyslexia: To read text finer

A debate on fonts for Dyslexia was not far-reaching until Luz Rello did research in 2013. He eye-tracked the reading speed of 48 dyslexic subjects in his research[2], which showed that Sans serif, monospaced and Roman fonts are better choices than italic fonts like serif and proportional. Further, the British Dyslexia association recommends Arial and  Comic San.

As depicted above, any individual can feel it facile to read when there is enough spacing, and the letters ensure better contrast. Luz Rello underlines three fonts as a comparison. Nonetheless, any font with relevant attributes can be befitting.  

Specialized fonts: Typefaces designed for dyslexics

Apart from suggestions among popular picks, a few fonts have been designed, keeping Dyslexics in view. These are Sylexiad. Dyslexie, Read Regular and Open Dyslexic. Among these typographies, Read Regular, Dyslexie, and OpenDyslexia are available and are free to use.

1. Read Regular

This typeface ensures the font is free from all unwanted details in letters, making readability finer. For instance, ‘g’ is simple and doesn’t come with a two-eyed form. Further, the font ensures the reader can differentiate between ascenders and descenders, also providing the best contrast possible.

2. OpenDyslexic

Being open-source typography to create content for Dyslexics.  This is available in regular, bold, and bold-italic styles. It has two typefaces: Opendyslexic and Opendyslexic Alta. The letters in this font are weighted down to implicitly represent the direction of each letter, making inference effortless. For those who bewilder the shapes and often process mirrored letters, OpenDyslexic can be obliging. 

3. Dyslexie

With a motive to create a typography that reduced the spinning and moving effect, Christain Boar created Dyslexie in 2008. Enticing attributes that make Dyslexie a great take-in are: heavier lines, light curvature, heavier bottom, and added spaces between words. Renske De Leeuw[3] in his master thesis studied the effect of this font on 43 students, 21 among them being dyslexia. The results found that Dyslexie led to overall reduced errors, thus ameliorating reading skills. 

4. Sylexiad

This is a collection of multiple fonts designed for dyslexics. Developed by Dr. Robert Hiller, a senior retired lecturer, researched[4] a new font family that can be fitting for dyslexic perspectives. The results and evidence of the research show these fonts working. Some of the popular fonts in this collection include: Sylexiad Serif and Sylexiad Sans

Fonts that dyslexics usually detest

Comprehending what attributes make a fitting font, one can determine what picks can be unfavorable for easy readers. Francesco[5] investigated how fonts and sizes can make decrease children’s fixations. The research found that increasing font size and character spacing significantly reduced the duration of the fixation and increased the number and amplitude of prosaccades in all groups of children tested. 

 Here are a few unfriendly fonts that can be preferably addressed to change. Some of these fonts come with irregular shapes, while others include many drive and funky strokes. 

  1. Papyrus: Designed in 1982 by a famous graphic designer, it comes with round edges and high horizontal strokes.  It was hand-drawn for over six months to give it a unique stance. Other chief attributes include irregular curves and high capitals. These features  makes it unfit for many readers.

Being an all capital sans-serif with angular attributes, it is distinct by its oblique strokes and concavity. Characterized by irregular shapes and curves, it makes it unfavorable for special readers. 
  3. Chiller: With an intriguing horror theme, this font comes with irregular shapes along with irregular and round edges. Nonetheless, many designers often pick it for printing and displays like brochures layout, comics and cards. Being irregular in shape, it is further arduous to infer. 
  4. Onyx: Being one of the decent fonts, it comes with a mix of thick and thin strokes. The high contrast between these strokes can be usually challenging to infer. Fonts like Didot and Times bold also come with similar contrasting strokes. This makes inference yet more complex.
