Vertical alignment in handwriting.
Whether the upright strokes in your letters all tilt the same way.
What vertical alignment means
Vertical alignment measures the tilt of the strokes that should be upright, and how much that tilt varies. It is close to slant consistency but measured on the stems themselves rather than on the letter as a whole.
The target is stability rather than verticality. A hand that leans consistently is fine here; what the factor penalises is stems that lean different amounts within the same line.
Why it matters
Varying stem angle is one of the things that makes writing look unsteady even when every letter is correctly formed. The reader picks up the inconsistency without identifying it.
It is also a good early indicator of grip and posture problems, because stem angle is set largely by how the hand sits on the paper rather than by letter knowledge. A tilt that changes as writing crosses the page usually means the wrist is rotating rather than the hand sliding.
What a good page looks like
A good page has stems that all lean the same way by the same amount, whether that is upright or slanted. Hold the page at arm’s length and the vertical strokes look like a comb rather than a scatter.
What usually pulls the score down
- The wrist pivoting through the line instead of the hand sliding along it.
- Paper set square to the desk rather than angled to the writing arm.
- Mixing print and cursive, which usually carry different natural angles.
- Writing across a page without moving the sheet, so the angle changes with reach.
How to practise it
Rows of plain upright strokes, evenly spaced, watching the angle rather than the spacing. This is the same drill as line quality but with attention on tilt rather than smoothness, and it is worth doing separately for that reason.
Then fix the setup. Angling the paper to match your writing arm, and moving it as you go, removes most of the variation without any practice at all, because the hand stops having to compensate.
The drill the report prescribes
Straight-stroke drills: l l l l kept upright.
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 stroke tilt stability 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
Is slanted handwriting worse than upright handwriting?
No. Both score well when consistent. The factor measures variation in the angle, not the angle itself.
How is this different from slant consistency?
Vertical alignment looks at the upright stems specifically. Slant consistency looks at the overall lean of the letters, including curved parts. They usually move together, and when they do not it points at a specific letter rather than a general habit.

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.
