The "normal" order for fact adjectives is

size, shape, age, colour / origin / material / purpose

Big is size and round is shape.

Adjective order follows a general pattern in English, and while it may seem a bit tricky at first, there's a guideline that can help you remember the right order. The usual order for multiple adjectives is:
1. Quantity or number
2. Opinion or quality
3. Size
4. Age
5. Shape
6. Color
7. Proper adjective (often nationality, origin, religion, etc.)
8. Material
9. Purpose or qualifier
So, in your example, you should say "big round" rather than "round big" because size comes before shape in the standard adjective order.
