Grid size has more of an impact on long term AAC success than you might think.
When we say “AAC success” we mean the goal of a child, teenager or adult being able to say whatever they want, to whoever they want, whenever they want to say it.
Giving them access to robust, reliable communication helps them to achieve this.
That’s where grid sizes come in.
Starting with a smaller grid size may seem like a good idea, but it makes communication harder.
With a small grid size, your child has to navigate through multiple pages to find the words they need.
And switching to larger grid sizes at a later stage can impact motor planning.
A larger grid size gives them access to:
✅ Robust, reliable communication from the start.
✅ Room to grow alongside their device.
By keeping the end goal in mind, AAC users are set up for long term communication support and success from the start.
