Are there "small" verses or "insignificant" verses?

[Link]

Is there such a thing as insignificant verse or small verse in Quran?

Or are they all so significant, to degrees we don't understand their significance, as the significance of each verse transcends us?

Are they all super important to find their place in Quran and know their role?  Or are there some verses that are not that important?

How do we know? How do we decide and judge which verse is more important than another?
