Not huge, smaller than I imagined.I thought my stamps were crooked, but it was the machine hot plate that was not level with the platform. I was close to replacing it with the same item, then I found a utube video on how to level these! Apparently a lot of them aren't level when u put them together, but u can level it by adjusting the screws on the hotplate area!(of course when the machine is OFF and not hot).It would have been convenient to know this instead of having to search u tube. Hope this helps!
