An ostrich egg is approximately 15.5 cm long, 12.9 cm wide, and has a circumference of about 45 cm.
To put that into perspective, here's a more detailed breakdown:
-
Dimensions:
- Length: Approximately 15.5 centimeters (6.1 inches)
- Width: Approximately 12.9 centimeters (5.1 inches)
- Circumference: Approximately 45 centimeters (17.7 inches)
-
Weight: While "size" typically refers to dimensions, it's worth noting that ostrich eggs also weigh significantly more than other eggs. They typically range from 1100 to 1950 grams (2.4 to 4.3 pounds), averaging around 1600 grams (3.5 pounds).
-
Shape: Ostrich eggs are more oval than chicken eggs. They have a shape index of 81-85%, compared to the 73-78% shape index of a chicken egg.
Therefore, when asking about the "size" of an ostrich egg, you're generally referring to its length, width, and circumference, making it considerably larger than other types of eggs.
