Short answer: Inconsistent letter sizing is common while handwriting is still a new skill and usually evens out with practice. If a child continues to write noticeably oversized and undersized letters within the same word or sentence well past the early writing stage, a handwriting assessment can help understand why.

Keeping every letter roughly the same height within a sentence requires a child to plan and control small, precise hand movements while also managing spacing, letter formation and spelling at the same time. Some children, especially while handwriting is still new and effortful, write one letter far larger than intended and the next noticeably smaller, not from carelessness but because keeping consistent size alongside everything else in writing takes real motor control.
Some variation in letter size is expected in early writing and tends to even out with regular practice over the first couple of years of school. It is worth a closer look when the inconsistency continues well past the stage when classmates have settled into more even sizing, when it happens even in short, simple, often-practised words, or when it appears alongside other handwriting difficulties like poor spacing or a tiring grip. A few parents near Vinod Nagar East have mentioned their child can write one letter that fills half the line and the very next letter barely visible, within the same short word.
An assessment looks at letter formation, size consistency and the underlying fine motor and visual-motor skills involved in writing, to understand whether this is a passing stage or a more persistent pattern worth targeted support. See our note on handwriting and pre-writing if other pre-writing skills are also a concern.

Not necessarily. Many children who do this are concentrating hard but still developing the fine motor control needed to keep letters consistently sized while managing everything else involved in writing.
Most children show noticeably more even letter sizing by around age 6 to 7, with further refinement continuing over the next couple of years.
They can be connected, since both involve fine motor control of the hand, but a child can have a fine grip and still struggle with size consistency, or the reverse.
Writing on lined paper with clear size guides and short, unpressured practice sessions can help a little, but a persistent pattern is better addressed with a professional assessment than ongoing correction alone.
