Notary in A4 Legal Size Paper. Is this an issue?

My notary signed my I797 and US address proof in A4 Legal paper instead of A4 letter. Is that okay? Or do I need to get it signed in A4 Letter size?
The A4 Letter size is : 8.5X11.0
The A4 Legal size is : 8.5X14.0

I think, it Shouldn’t be an issue

Sure. Thank you for your response.
