A classic original Ritz cracker is about 1.8 inches (46 mm) across in diameter.

Quick Scoop

  • Shape: Round, disc-shaped cracker.
  • Diameter: About 46 mm, which is roughly 1.8 inches.
  • Area: That works out to around 10.2 square centimeters (about 1.6 square inches) of surface area per side, treating it as a simple circle.
  • Thickness: The manufacturer doesn’t publish an exact number, but people have noticed that newer Ritz crackers seem a bit thinner than older ones due to shrinkflation trends.

If you want a quick real‑world feel: a Ritz cracker is just a little smaller than the width of a standard business card’s short edge (2 inches) and fits neatly in one bite for most adults.
