Did you know that one of the most important tools for success is a good pencil/pen grip? It increases the speed and fluency of writing. Furthermore, research has shown the greater the quantity of work produced, the better the quality.
Most children are taught the dynamic tripod grip when they start school – pencil held between the thumb, index finger and middle finger. It is the grip that occupational therapists and teachers look for, and for good reason: it allows small, controlled movements with minimal effort.
But in older primary school children, something shifts. Many who started with a functional tripod grip begin wrapping their thumb over the pencil and index finger. This is the thumb wrap grip, and it is one of the most common grip changes teachers notice in Key Stage 2.

Does grip style affect handwriting?
Research on pencil grip is more nuanced than many classroom charts suggest. Studies have found that grip style alone does not significantly affect legibility – children using a range of grips can produce perfectly readable writing.
Where the thumb wrap grip does differ is in the force it requires. Research has shown that the dynamic tripod grip produces significantly less grip force and less pressure through the pencil point than the thumb wrap. Over short bursts of writing, this makes little difference. Over the sustained writing expected in upper primary and secondary school – extended answers, timed assessments, end-of-year exams – the extra force adds up.
The potential consequences include hand pain during longer writing tasks, reduced writing speed and efficiency, decreased control over pencil placement on the page, and premature fatigue that affects the quality of work towards the end of a task.
For a child who only writes a few lines at a time, the thumb wrap may cause no problems at all. For a child facing 45-minute written exams, it can become a significant barrier.
What is happening in the hand
The thumb wrap grip changes which muscles do the work. In a dynamic tripod grip, the opponens pollicis muscle controls the thumb – the same muscle used for fine, precise movements. When the thumb wraps over, the child recruits the adductor pollicis instead, a stronger but less precise muscle that pulls the thumb inward.

This gives a firm, stable hold – the pencil is not going anywhere. But that stability comes at a cost. The hand loses the small, quick movements needed for fluent letter formation. Children using this grip are often less comfortable drawing lines and basic shapes, and their view of what they are writing is partially blocked by the palm of their hand.
Supporting your child
If your child has developed a thumb wrap grip, the goal is not to force a change overnight. Grip patterns are deeply embedded motor habits, and correction under pressure often creates anxiety around writing – which makes things worse, not better.
Instead, focus on strengthening the muscles that support a more functional grip. Activities that build thumb strength and fine motor control include:
- Cutting or tearing paper – using different types and textures
- Using a hole punch to make holes or create patterns in paper
- Rolling out playdough with a rolling pin using both hands
- Pushing small objects, coins, pieces of Lego or cutters into playdough
- Putting coins into a piggy bank
- Popping bubble wrap with individual fingers
- Playing board games with small pieces that need to be grasped and moved with fingertips
These are not handwriting exercises. They are activities that build the hand strength and coordination that a functional grip depends on. Little and often is more effective than long, focused sessions.
Pencil grips and ergonomic pens can help some children transition to a more functional hold, but they work best alongside the strengthening activities above rather than as a standalone fix.
When to seek support
A thumb wrap grip on its own is not a cause for alarm. But if your child avoids writing, complains of hand pain, writes noticeably more slowly than their peers, or produces work that does not reflect what they can say aloud, it is worth a conversation with their teacher or an occupational therapist. Grip is one piece of a larger picture – and understanding the full picture is what leads to the right support.
Where does your child’s handwriting stand?
Handwriting Scan and Handwriting MOT from More Handwriting are designed to assess letter formation, fluency and automaticity for children aged seven and above – giving you a clear picture of what is working and what needs attention. For children aged two and a half to three and a half, The Scribble Report looks at early mark-making development. Visit morehandwriting.co.uk to find out more.
