H 1.6" x D 8.3", this full sized plate shines when baby goes for more solid foods, usually around 1 to 1.5 yrs old. It is perfect for things like pizza/ sandwiches/ omelettes etc. Sandwich plate is also great for adults to enjoy more mature dinner or breakfast dishes. The vertical wall prevents food from falling off the plate easily and provides a support for toddlers to pick up their meal easier than traditionally shaped plates.Bonnsu LLC
