3-3/4" Dia. Burger Press Now you can punch out perfect burgers every time, all exactly 3-3/4" dia, which, not coincidentally, is just the right size to fit inside your standard commercial hamburger bun. Our sturdy plastic hamburger press is 4-1/2" tall with a big plunger that's quite satisfying to smack down into the minced meat. Also dandy for hash browns, crab cakes, giant cookies or anything else malleable that you think should be circular.
