Two eye movement experiments investigated intraword spacing (the space between letters within words) and interword spacing (the space between words) to explore the influence these variables have on eye movement control during reading. Both variables are important factors in determining the optimal use of space in a line of text, and fonts differ widely in how they employ these spaces. Prior research suggests that the proximity of flanking letters influences the identification of a central… 
Breaking down the word length effect on readers’ eye movements
TLDR
Saccadic measures including relative landing position, refixation and skipping probability were strongly affected by spatial width and slightly affected by the NrL, which suggests that saccadic programming and parafoveal processing of upcoming words are limited by visual acuity more than by attentional factors.
Interword and interletter spacing effects during reading revisited: Interactions with word and font characteristics.
TLDR
Findings from 3 experiments designed to resolve the seemingly inconsistent letter-spacing effects and provide clarity to researchers and font designers and researchers indicate that the direction of spacing effects depend on the size of the default spacing chosen by font developers.
The effects of crowding on eye movement patterns in reading.
Effects of inter-character spacing on saccade programming in beginning readers and dyslexics
TLDR
It is concluded that the beneficial effect of increased inter-letter spacing on reading can be better explained in terms of decreased visual crowding than improved saccade targeting.
Adult Age Differences in Effects of Text Spacing on Eye Movements During Reading
TLDR
It is concluded that visual rather than lexical processing is disrupted more for older readers when text spacing is condensed and discusses this finding in relation to common age-related visual deficits.
Wider Letter-Spacing Facilitates Word Processing but Impairs Reading Rates of Fast Readers
TLDR
It is tentatively proposed that wider letter spacing reinforces serial letter processing in slower readers, but disrupts parallel processing of letter chunks in faster readers.
Manipulating Interword and Interletter Spacing in Cursive Script: An Eye Movements Investigation of Reading Persian
TLDR
The experiments show that providing the readers with inaccurate word boundary information is detrimental to reading rate, and the properties of Persian script were utilized to investigate the effects of reducing interword spacing and increasing the interletter distance (ligature) within a word.
Parafoveal Preview Effects in Reading Unspaced Text
TLDR
An eye tracking experiment examined the impact of removing spaces on parafoveal processing and points toward a system that prefers narrowly focused processing of a single word, at least when means for easy word segmentation are available.
The effects of interword spacing on the eye movements of young and older readers
Recent evidence indicates that older adults (aged 65+) are more disrupted by removing interword spaces than young adults (aged 18–30). However, it is not known whether older readers also show greater

Effects of increased letter spacing on word identification and eye guidance during reading
TLDR
The spacing manipulations were found to modulate the effect of word frequency on the number and duration of fixations on target words, indicating, more specifically, that letter spacing affected actual word identification under various word-spacing conditions.
Effects of number-of-letters on eye movements during reading are independent from effects of spatial word length
Word length is an important determinant of eye movement behaviour in reading. The current study is the first attempt to disconfound a word's number of letters from its spatial extent. In a

The impact of letter spacing on reading: a test of the bigram coding hypothesis.
TLDR
The hypothesis that the fast recognition of combinations of nearby letters plays a central role in the coding of words, such that interfering with this representation prevents the parallel analysis of letter strings, is supported.
Eye movements while reading and searching spatially transformed text: A developmental examination
TLDR
Although reading and search were found to be sensitive to the same types of spatial manipulations, discrepancies of span and speed suggest qualitative differences; comprehension demands during reading can account for these differences.
Interword Spacing in Chinese Text Layout
TLDR
The results of the present study suggest that word spacing in Chinese text layout enhances reading performance, and may help the reader to segment more quickly a string of characters into words and reduce the likelihood of misinterpretation.
The effect of letter spacing on reading speed in central and peripheral vision.
TLDR
Examining whether reading speed can be improved in normal peripheral vision by increasing the letter spacing found increased letter spacing beyond the standard size does not lead to an increase in reading speed in central or peripheral vision.
Effect of letter spacing on visual span and reading speed.
TLDR
The size of the visual span and the reading speeds measured by the two presentation methods showed a qualitatively similar dependence on letter spacing and that they were highly correlated, consistent with the view that the size ofThe visual span is a primary visual factor that limits reading speed.
