Components and Control Count

Posted on by JasonD

I have a pretty large application that I am building and I am having to rethink things. I am taking two of the pages and merging them into one control, but that control will be something that I place on all of the remaining pages.

So if I have 30 controls in the component and I place that component once on each of the 11 remaining pages doe the app treat that as 330 controls or just as 30 controls since only one component will be loaded at a time?

Hi @JasonD,

Power Apps treats a component as one control per screen, regardless of how many controls are inside it.
So a component with 30 controls used on 11 screens counts as 11 controls total, not 330.
Only the active screen is loaded at runtime, so this approach improves maintainability and performance and is considered a best practice.

Great question—this is an important design consideration for large apps

In Microsoft Power Apps:

It is treated closer to 330 controls, not just 30.

Each component instance counts separately
Your scenario ≈ 330 controls
Only one screen renders, but all affect performance

Best approach: balance reuse with control count optimization

Hello @JasonD,

It depends on what’s actually loaded at runtime when you navigate to a screen. Only the controls on the current screen are rendered in memory, not the whole app.

So even if you use the same component on 11 screens, it’s not like all 11 are active at once. If only one screen is open, then only that instance (around 30 controls) is being used. So no, it not be treated as 330 controls at once.
