Letter spacing in handwriting.
Whether the letters inside a word sit at even distances from each other.
What letter spacing means
Letter spacing is the gap between letters within a single word, as distinct from the gap between words. It is measured as regularity: whether the spaces inside a word are all about the same, rather than whether they hit any particular width.
The gaps do not need to be equal in the printed sense. Some letter pairs naturally sit closer than others. What the factor looks for is the absence of surprises, letters that suddenly crowd together or fall apart in the middle of a word.
Why it matters
Uneven internal spacing creates false word boundaries. A large gap in the middle of a word reads as a space, so the reader briefly parses one word as two and has to back up.
It also interacts badly with word spacing. If the gaps inside a word approach the size of the gaps between words, the distinction collapses and the line becomes a string of letters, which is the hardest state to read a page in.
What a good page looks like
A good word holds together as one object. The spaces inside it are visibly smaller than the space that follows it, and none of them is noticeably wider than its neighbours. The word looks like a unit before you read it.
What usually pulls the score down
- Mixing joined and unjoined letters within a word, which leaves gaps where the joins stop.
- Slowing down mid-word, which usually widens the next gap.
- Very narrow or very wide letters placed next to each other without adjusting.
- Squeezing the end of a word to fit the remaining line width.
How to practise it
Write slowly with a deliberate small gap between every letter, wide enough that you have to place it. A matchstick width is the traditional reference and it is about right. This exaggerates the space, which is what makes it controllable.
Then write the same words at normal speed and compare. The aim is not to keep the exaggerated gap but to have felt where each gap is, which is enough for most writers to even them out.
The drill the report prescribes
Spaced-letter slow writing: a matchstick gap between letters.
How Vahini measures it
A scanned page gives the analyser the finished writing, not the movement that produced it, so this factor is read from intra-word spacing proxy and reported as such. The Vahini pen senses the movement directly, which is the difference between inferring how a page was written and recording it.
Questions
Should I join my letters or not?
Either works. What costs points is doing both inside one word, because the join and the gap produce different spacing and the word ends up uneven.
My letters are cramped. Is that a spacing problem or a size problem?
Check whether the gaps are even. Cramped but even spacing is a style; cramped and uneven spacing is what this factor is measuring.

The analyser scores a photo of a handwritten page on all twenty factors, names the two worth working on first, and prescribes the drills for them. It is free, it needs no pen, and it is an educational tool rather than a medical assessment.
