GetDesiredSize of Text Widget Return 0

Is it true that text widget in Blueprint, GetDesiredSize() always return zero regardless of any text entered in that widget?

Here’s an unresolved issue as well:

Hello Pelangi,

After doing a bit of digging I was able to find a post with information on this subject. I have provided a link below. I hope that this information helps. As a note, you maybe getting a return of zero because the the widget has not been fully added to the screen when you are calling “Get Desired Size”. There is a chance that calling this on Event Construct will return 0,0 because it is being called before the widget you are testing has been fully added. As a test you can call this on tick to see if you are given any values. As stated above, see the linked thread for more information.

This can be remedied by using “Force Layout Prepass” before “get desired size”


thank you
that was helpful

This worked for me in UE4.26 on a rich text block. The rich text block is inside a canvas panel and is set to auto-size and auto word wrap.


// The rich text block to use for displaying the text.
UPROPERTY(Transient, meta = (BindWidget))
URichTextBlock* DynamicRichTextBlock;


UE_LOG(LogTemp, Warning, TEXT(“DynamicRichTextBlockSize %s”), *DynamicRichTextBlock->GetDesiredSize().ToString());
return DynamicRichTextBlock->GetDesiredSize();
