How much wider are New Balance wide shoes?

I'm curious to know just how much wider the wide shoes from New Balance are compared to their regular offerings. Are they significantly wider, allowing for more room and comfort for those with wider feet? Or is the difference subtle, perhaps only noticeable to those who have tried both? It would be helpful to know the specific measurements or percentages of how much wider they are to make an informed decision on whether they're the right fit for me.
